LAVFilters don't seem to deinterlace this video.
I tried mpv vlc kodi mpc-be and they all deinterlace it properly.

Hi

Latest version used, I'm trying to open .avs file in Windows Media Player and GraphStudio (using LAV Splitter Source). If AVISynth installed I can open .avs file without any issues.

So, maybe it's bug, maybe I'm doing something wrong, but as I see in changelists AVISynth file is supported.

Script is very simple

DirectShowSource("c:\samples\video.mp4", fps=25).ConvertToRGB32()

Sample: https://www.sendspace.com/file/54t8z2

No matter how "Use Stream Aspect Ratio" in LAV Video is set, it will always use 160x120, not the 1000x130 set in the mkv container (crazy value for testing purposes).

With the latest drivers from nvidia on my 960gtx i get very low framerate for hevc main10 300mbps (crowd video). With 361 everything works fine. (Win10 x64)

I`m trying to compile ffmpeg with build_ffmpeg.sh under cygwin in windows 7 amd64, but getting:

Building ffmpeg in GCC x86_64 Release config...
ERROR: libspeex not found

libspeex.a is in ../thirdparty/lib64(lib32), cant realize, what im doing wrong.

RGB32 color space vertically flipped output option is missing, and some player and input format combinations produce upside-down video image.

All .exe files are blocked - compressed formats are allowed.

Suggest a version in either .7z or .zip is created to bypass blocking of .exe files.

K-Lite Codec Pack 11.8.0 (MPC-HC 1.7.10.40 + LAV Filters 0.67.0.30)

Usually, I uninstall the old version, before installing the new one. The installer should not remove the settings or should ask if it should remove the existing settings when uninstalling LAV Filters, or it should ask the user if it should reset the settings when installing. I don't know what case it is, out of these two.

Selecting CUVID in LAV Video Decoder within MPC-HC prevents videos from playing when SLI is enabled. The behavior is prevented if SLI is disabled or DXVA is selected instead.

A similar ticket was opened here: ysh1101/lavfilters#545

I'm using Lav Splitter Source on my project, but there is a problem.
I create a IAMTimelineObj to load a mp3 audio clip, next I set the Lav Splitter Source Filter on the timeline using the SetSubObjectGUID method.

Everything works fine, and if I load the audio clip and play a part of it (using IMediaSeeking.SetPositions on the renderer) the audio starts and stops correctly, but when the audio ends, the mediacontrol is blocked. I can't receive the complete event, and if I try to stop the Graph, the mediacontrol hangs on stop function.

Am I doing a something wrong? Or is there a bug on the splitter source?

LAVvideo.ax won't register on Windows XP SP2.

Hello.
My media player allows user to see two separate subtitles simultaneously (useful when learning language, for example) - http://puu.sh/orbtZ/1e0e4eb740.jpg, but currently I use modified MPC-BE codecs as internal codecs (so user don't have to install anything) to make it work.
But, due to inconsistent updates of MPC-BE codecs, I want to switch to LAV Filters.
So, I would like to ask you: can you please add support for two subtitles pins? So I don't have to keep two copies of LAV Filters - mine and your master, and merge it, because otherwise users became dependent on how frequently I will update LAV Video and they will be not be able to use your official version.

Regards, Dmitry

MPC-HC settings:

LAV Video:

[x] treat 25p movies as 24p (requires Reclock or VideoClock)

madVR switches the monitor to 24 Hz when playing PAL video (http://mir.cr/0TO7HKQ7) and to 30 Hz when playing NTSC video (http://mir.cr/0JGNT9O8). It causes dropped frames.
If we perform YADIF deinterlacing with ffdshow madVR behaves correctly (doesn't switch when playing PAL video 'cause there's no 48 Hz mode and switches to 60 Hz when playing NTSC video).

Hi, I am using LAV Video Decoder version 0.67.0.69-git with a Nvidia 840M GPU on Windows 10. The CUVID acceleration would show as "avcodec" when CUVID is selected and a video is playing. On my other machines running on the same LAV versions, Windows 10, and same Nvidia driver versions (Newest Stable drivers frim NVIDIA), the CUVID acceleration would work fine, and those 2 machines are using a GTX 770 and GT 430.

Any Suggestions?

LAV video decoder outputs bad frames with dotted mosaic-like blocks when decoding some interlaced h264 videos in dxva2n mode

GPU in use is Intel HD Graphics 3000 (sandy bridge) with latest driver (9.17.10.4229)

Latest version of LAV video decoder that would work in dxva2n mode with those interlaced h264 videos is 0.64.0

Hi there,

I would like to get some filters setup to allow my OS to play MKV files, but in testing LAVFilters I found something worrying. Every time I launch an application using the filters it attempts to connect to the Internet. I am confident this is related to the filters, since the application never requested Internet access in the past. The filters attempted to connect to the IP addresses 23.64.171.27, 23.4.59.27,
and 23.65.11.27 in the three times I tested it. The addresses seem to resolve into symcd.com domains. There were many warnings of viruses and trojans on Google searches of the IP addresses that seemed to be related to this domain.

I cannot see anything in the settings regarding checking for version updates or anything that would explain why the filters are attempting to go to the Internet. I can't be bothered to setup a sniffer right now, but perhaps someone here can explain to me why the software is attempting to communicate on the Internet instead of simply decoding the videos?

Thanks,
Eglin

LAV Source show incorrect stream's name. Stream's name store in Cyrillics(CP 1251).

I just discovered that playing HEVC using CUVID decoder crashes MPC-HC.
I don't know if it's caused by CUVID, MPC or LAV (Video decoder), but I suppose I can start here.

In the past I did set it up to play 1080 and 4k using the GPU via CUVID, and it di play the test vids.
Now I used a HEVC encoded file and MPC-HC just crashes; I discovered I can play the file with CPU decoding, but not with the GPU (CUVID).

My GTX660 is supposed to be able to play 1920x1080 HEVC video so I'm puzzled.
Here's a dump: https://drdump.com/UploadedReport.aspx?DumpID=5713660&SecondVisit=1

It seems to point to some CUVID thing, and being LAV Video decoder the only thing that uses it I suppose it's a bug? I hope it's something that's possible to fix...

(Windows 7 64bit, NV Drivers 359.00, MPC-HC 1.7.10.28 (0115ec4), LAV 0.67.0.3-git, madvr 0.89.17)
If you need other data just ask.

I noticed that when setting decoding mode to DXVA copy back, selecting output format to YV12, and decoding HEVC 10bit video files, I got grayscaled magenta picture.

NV12 is working fine. AVC is fine.

Reproduced on Win10 x64, GTX 950, MPC-HC / DirectShowSource2.

This problem started in version 0.66. Audio in some TS files with a Dolby E track (broadcast lossless audio format) is not detected. Only MPEG audio and other common formats show up under the audio track selection tab.
I am using Media Player Classic 1.7.9. If I go back to LAV version 0.65, the audio track is detected and I can bitstream it to an external decoder perfectly.

This is a TS file with this problem: https://drive.google.com/folderview?id=0B09XfeCqRrZbYjlWTUQzUzZjd3c&usp=sharing
And this are 2 TS files with working Dolby E audio: https://drive.google.com/folderview?id=0B09XfeCqRrZbY0JyNnVhQkFTczg&usp=sharing

I had run into an issue where mp4's were just loading black, rather than playing the video.

Installing LAVFilters through the exe linked here: http://forum.doom9.org/showthread.php?t=156191 and then adjusting codec settings via Win7DSFilterTweaker 5.9

Running the batch install files in an admin shell (Windows 10) the same issue with an mp4 just showing as black was present, even after setting the preferred codes in Win7DSFilterTweaker 5.9.

Just installed a K-Lite Codec Pack 12.01 and I have an issue playing an MP3-file through in-game player of some game.

So, I have two types of MP3 files:

• First:

  Audio
  Format                      : MPEG Audio
  Format version              : Version 2
  Format profile              : Layer 3

• Second:

  Audio
  Format                      : MPEG Audio
  Format version              : Version 1
  Format profile              : Layer 3

When I play both of them through MPC, the LAV Audio Decoder and ffdshow Audio Decoder are used and LAV is saying that input codec is mp3float. When I play both of them through the in-game music player, only the LAV Audio Decoder is used and is saying that input codec is mp1float.

When I play both of them through MPC, no issues happen. When I play the first one through the in-game music player, also no issues happen. But when I play the second one through the in-game music player, I hear loud high-pitch whistling for about half a second.
If I go to LAV Audio Decoder's Properties -> Formats and disable it for mp2 and mp3 file types — no issues happen anymore.

Also, I've found that some people had been experiencing similar issue with another game back in October, 2012.

If I play a dash mp4 file downloaded from youtube I can't jump to a specific time with MPC-HC or MPC-BE anymore. If I use the built in Filters of MPC-BE it works.

I don't know what you need, so all info that I can get from MPC HC.

What is going? File open in the MPC HC, but stuck on 0:00:00, it says it are playing, but nothing are playing and absolutely none progress on GUI.

All other video in various formats plays fine, but not it.

Edit: Oh fine, it occurs on 0.67.0.3-git and 0.67 stable as well.

When LAVVideo.ax is registered as Filter in Windows 10 x64 v1511 build 10586.36, it is not possible to open create Graph Filter because it crash on expanding DirectShow Filter tree in "Insert Filters".
When LAVVideo.ax is unregistered, GraphEdit is working correctly.

when using ILAVVideoSettings.SetHWAccel(LAVHWAccel.HWAccel_QuickSync), decoder leaves unreleased HDC handles. Im not sure, if the problem is in QuickSync (latest version) or in its initialization/deinitialization on LAV side.
RuntimeConfig settings have no effect on the leak.

problem orrurs, when you use LAV+QuckSync multiple times (like playing short spots/movies in a loop)

Hi ,

I'm currently using Potplayer (64-bit) with LAV filters 0.66.0. However, I experienced constant program crash when I try to open a MKV file with two HDMV/PGS (SUP) tracks. I'm almost certain that the problem is about LAV Splitter and the PGS track, because (1) the problem is solved as soon as I removed the PGS tracks from the video file using MKVMerge 8.4.0 64-bit version, and (2) the problem is also solved without removing the PGS tracks when I switch to another splitter (ffmpeg splitter is the one I tried). I hope this problem can be fixed in future updates because I don't want to switch to another splitter every time I watch this video.

P.S. I just did a further research and removed only one of the two PGS tracks. The crash didn't occur. So it seems that LAV Splitter has trouble handling MULTIPLE PGS tracks.

P.P.S FURTHER research. I examined further by removing the DEFAULT track but leaving the secondary track. Initially the program crashed. Then I examined the flags in MKVToolNix, I found the difference is that the "default track" flag for the previous secondary track (now only and primary track) is marked as "determine automatically". I changed it to "yes" and remux the file, and guess what, it now works. The program doesn't crash now. So further conclude all previous experiments, it seems that LAV Splitter has trouble handling PGS tracks with a "determine automatically" "default track" flag.

Hello,
firt of all...good work nevcairiel! LAV filters are my favourite.
I play regularly short 4k or HD clips on my tv in my living room for deco reasons, using a small Haswell miniITX computer and a r7 radeon and VVVV software. I noticed that after a long time the VVVV patch suddenly closed always, and tracked the problem due to a shortage of memory. I then reproduced the problem playing them in MPC, and had the same results. The problem is when VVVV or MPC loads a new/different video, it's ram footprint get bigger and bigger (maybe 500kb or 1 MB each new video). This ony occurs if QuickSync HW acceleration is enabled. I also want to point out that the intel iGPU does not render as the TV is plugged to the radeon. And that I use Haali Splitter and Mkv/H264 videos, some with audio and no subtitles at all.
Attached is Graph I use and some other info I got from my computer. I tried LAV filter 0.65 and 0.66.
If you need any other info please tell me.

Thanks for making these awesome filters.

Then put that info on your website and put it in the installer and put a check in the installer instead of letting it trip all over itself and fuckup at the end of install!

When the episode was played, I could view the video track of the segmented chapter, but the audio wouldn't play. When I tried to play the segmented chapter itself, it would play perfectly, both video and audio track.

Also, I tried to use Haali Media Splitter instead of LAV Splitter (but still using LAV Filters), and the segmented chapters wouldn't appear at all on the player. But for another track which had the same audio codec for its segmented chapters, they'd load just fine.
I also tried using a portable VLC, but surprisingly the segmented chapters played just fine, both video and audio, despite the audio having different codec.

Example files here:
The main track: An episode of an anime
The segmented chapters: First segment: opening of the episode, Second segment: ending of the episode

For convenience, LAV Audio should fallback to decoding if bitstreaming fails

Hi there, I've been doing a lot of tests, And I found out that when I'm using LAV Video, I got freezes on some x264 videos on some parts of the video on seeking. If I change the video to MPC-HC Internal, even keeping LAV Audio and LAV Splitter. No more freezes. I've test the video on VLC and it play fine too. (I've CCCP installed)
I've tested changing seek options on MPC-HC, but nothing, I changed to Kawai codec, and the problem existed too. So I'm preety sure the culprit is Lav Video.
I've tested with all LAV Filters since: 0.60.1 till the last one 0.67, and in all versions the problem exist :/

With 0.58.2 -The freeze doesn't exist but it appears this bug: http://i.imgur.com/sJU9gnd.jpg
With 0.59.1.26 - The bug above is gone, but it begins the freezing, but it has a lot of freeze way more then on 0.60.1 above, since on 0.6x versions I just see 1 or 2 "keyframes" that freezes.

I though it could be about x264 settings. but I have 2 videos with the same settings, and the problem just exist in one of the videos -.-

And I encoded an mp4, and the original one doesnt have the freezing. -.- But I I've many encodes of mines with the same settings and the problem doesn't exist. :s

If you need more information about this, please ask.

LAV Splitter should allow to select the active program in MPEG-TS and other formats that expose them.
Programs are also used in HLS streams for different variants.

I have some weird sound distortions bug with OPUS encoded on very low bitrate
Decoding opus with opusdec gives normal sound. No distortions. So it definitely something with LAV Audio Decoder
on 2 chanels it's start from < 48kbps
on 6 chanels it's start from < 224kbps
here is samples
http://www.mediafire.com/download/tiab1o4w6wtb6j3
encoding on high bitrates is not an option since opus is designed for low bitrates (better then to use aac for compatibility)
also 0.62 version doesn't have this bug, so I fall back LAVAudio.ax to it and it's sounds OK

PS: yea.. now there is "issues" section finally :)

MPC-BE developers added just recently support for WebVTT subtitles in r1405.

Hello!
It seems like LAV video decoder has troubles with decoding some old quicktime files.
Decoded frames look like this:

Instead of this:

Fisrt picture is taken when video is decoded with LAV 0.67, second picture is taken when video is decoded with internal MPC-BE decoder.

H264 MKV not decoded by DXVA hardware, but by processor unity.

1° option: DXVA2 COPY BACK. (not working)
2° option: none

Native DXVA2 always never work before. Other codecs work fine. Other LAV ancient versions work fine.

Hello, I had to rebuild a computer and am pretty sure that I had it working this way before. I make MP4 Files with three audio tracks. AC3, AC3-Passthrough, and DTSHD-Passthrough. I do this to make the files compatible with 360 Extenders, Android, and also to get the best audio when played in my basement home theater which is the computer I have the issue with. If I select to bitstream all of the formats the files do not play. If I uncheck all the bitstreaming options they will play. Previously, I believe LAV would select the best audio and bitstream if applicable and not bitstream if not applicable. I don't remember EVER having a file that wouldn't play on the computer. Am I doing something wrong? Has something changed? I want LAV to select the best audio (HD if available and bitstream to my receiver). Thanks in advance. Forgot to mention....for kicks, I ripped a bluray with ONLY a HD track and it played brilliantly with all the boxes checked.

Hi,

I have Surface Pro 4 with Intel HD Graphics 520 and while trying to play a movie:

Video: HEVC 3840x2160 29.97fps [V: hevc main, yuv420p, 3840x2160]
Audio: AAC 48000Hz stereo 194kbps [A: aac lc, 48000 Hz, stereo, 194 kb/s]

with:

MPC-HC (Nightly, 64-bit)

Build information:
Version: 1.7.10.130 (6d03440)
Compiler: MSVC 2015 Update 1
Build date: Apr 2 2016
LAV Filters:
LAV Splitter: 0.68.0.0
LAV Video: 0.68.0.16
LAV Audio: 0.68.0.16
FFmpeg compiler: MinGW-w64 GCC 5.3.0
Operating system:
Name: Windows NT 10.0 (build 10586)

Hardware:
CPU: Intel(R) Core(TM) i5-6300U CPU @ 2.40GHz
GPU: Intel(R) HD Graphics 520 (driver version: 20.19.15.4380)

with QuickSync hardware acceleration then processor usage is at 100%:

but when switched to DXVA2 then usage is on around 7%:

I have tried 3 diffrent drivers versions and 0.67 and 0.68 LAV Video Decoder versions and have same issue.

Maybe it is a issue with QuickSync in LAV Video Decoder?

Best regards,

I have a file with E-AC-3 audio that when played, has no sound. I can play the E-AC-3 track fine in VLC media player. Also, If I switch LAV Splitter to use the alternate stereo AAC audio track, the audio plays.

This looks off to me as the media type does not indicate E-AC-3 but instead show only AC3. Also, the number of channels, sampling rate, and bit rate are way off.

This sample has artifacts when HEVC DXVA. The problem occurs on Nvidia and Intel.

LAV Video Decoder 0.67.0.30-git.

The source/splitter filter isn't reporting progress properly for .265 files.

Hi!
I use the "advanced" options in LAV splitter for selecting subtitles in MPC-HC and it works fine. However, it'd be great if the advanced subtitle rules would be re-evaluated when I switch audio streams.

E.g. an MKV (containing English and German Audio, English and German normal subtitles plus English and German forced subs) starts with English audio and LAV correctly selects the English forced subs according to my rule:

eng:eng|f ger:ger|f :|d

But when I then switch to German audio in MPC-HC, I'd expect the subtitle selection to switch to German forced subtitles automatically. This does not happen. It still uses the English ones that were activated when the player started.

So obviously, the only thing missing here is the option to re-check the LAV splitter subtitle options when the audio track is changed. Would be nice if this could be implemented!

Thanks!

I am using LAV video decoder to decode mpeg-2/h264 streams received from network (multicast).
It seems that there is a memory leak problem while decoding h264 streams.

Memory leaks are especially strong when loss of input packets present. For test purposes, I stream video from VLC to my application that uses directshow graph. When I insert some "spoiling" of input stream (for example changing the playing position in VLC) memory consumption significantly increases. I was not sure that memory leak is in the decoder, but I did some testing with deleting filters from the graph manually and found that when I free up the decoder, almost all allocated memory is freed.

I aslo did some testing with VS2015 memory profiler (using LAV .pdb files). The picture below shows signiicant memory increase after several changings of playing position in VLC. (snapshot 2). Snapshot 1 - heap before "spoiling" input stream with VLC. Snapshot 3 - another, smaller portion of "spoiling".

Unfortunately, I can't see where exactly this leak appears, maybe because I don't have enough .pdb for all components of LAV filter. Blocks with leaked memory have "undetermined" type, and the module with leak is undefined too (VS 2015 shows the module with memory leak as "External"). Pictures below show it:

I don't use any HW acceleration for video decoding.

When I do same things with mpeg-2 compressed video, I don't observe such problems.

I can't play this file -> I get so sound.
VLC media player can play it.
