"How do I insert every 10 or 15 minutes?"

Hello.
Uses latest x9k3 and threefive. H264 working ok, but Mpeg2 splits with different segments duration(not 2 default seconds). It happened on file or live UDP streams. Looks like it cannot found i-frames in stream.

when Udp stream contains scte35 stream, hls shows some jerks and glitches. whereas when udp stream without scte35 is used it run smoothly. @futzu please help.

When x9k3 is restarted it could keep media-sequence going on - it would reread last index.m3u8. If developer want's to reset mediaseq it could just delete index.m3u8 before start.

Reason: if we run x9k3 on LIVE and sidecar.txt gets big, we can't delete sidecar.txt without breaking clients. (when sidecar.txt is deleted x9k3 crashes).

Alternative could be to allow to receive sidecar txt lines using TCP/UDP just to leave sidecar.txt out.

I'm new to the stream business, I still don't understand it very well, I have a hls stream http://localhost:8787/live/stream-1080p.m3u8 and I want to send a commercial ad signal inside it, what would that be like? this would be for the person to overlap this stream with their commercial

I'm using tsduck to inject SCTE35 Markers with
...
<splice_insert splice_event_id="0x00000001" out_of_network="true" splice_immediate="true" unique_program_id="0x0001">
<break_duration auto_return="true" duration="2,150,000"/>
</splice_insert>
...
However, the ad breaks runs forever:

#EXT-X-CUE-OUT-CONT:825.560/23.888889
#EXTINF:3.840,
seg1796.ts
#EXT-X-CUE-OUT-CONT:829.400/23.888889
#EXTINF:3.840,
seg1797.ts
#EXT-X-CUE-OUT-CONT:833.240/23.888889
#EXTINF:3.840,

I'm a total python newbie, but looking at the code, the _auto_return is never called / tested. Where should I insert the auto-return test?

Great tool, btw! Adds the last missing piece to the ffmpeg / tsduck eco system.

hi my brother.
you have PayPal account? or BTC/ETH ?
I need to sent some Christmas gift

I am new to the field of video production, and I was attempting to use x9k3 to solve a problem, but I am not certain if it is the correct tool. I was hoping I might be able to contact you via email or even jump on a phone call.

I am working with a company that produces live streamed events. We save the video stream from those events, and then also make them available as VOD on different platforms. I would like to integrate with google ad manager, but google requires "preconditioning" the videos. In particular, I would like to do server-side ad injection (SSAI, also often called DAI) using a stitcher. I see that google ad manager can accept an MRSS feed (which has a google-specific namespace to identify cue-points) or they can accept files from BrightCove.

My goal is to allow my content editors to create a new piece of content (maybe an edited live stream or even a highlight reel pieced together from many streams). I would then like the editors to be able to place ad breaks (maybe cue-points, maybe SCTE 35 markers, I'm not sure) into the video at any points they choose. I attempted to do this with your x9k3 tool and adbreak tool, but it seemed as if the resultant m3u8 file was not re-encoded (but rather just split on the nearest I-Frame) - I say this because it appeared that the cue-out was not at the offset I had configured, but somewhat close.

I would like my users to be able to place ad breaks at specific locations and then have google ad manager respect those locations - possibly by having an MRSS feed that google ad manager can ingest. I am somewhat shaky on the details since it seems redundant to me that I should need cue-points in the MRSS feed but then also need the m3u8 file to reflect those same cue points.

In short, I would be very grateful for any assistance you might be able to provide to help me solve this problem. If you know how to add ad breaks to existing videos so they work with google ad manager server-side ad injection, I would love to learn how. I am also happy to compensate you for any assistance, or I would be grateful if you could refer me to another person if you are not familiar with this particular situation.

Thank you.

Hello

I'm testing x9k3 to obtain a live signal with multiple scte35 cues. I've installed using the instructions, and tried to run the replay mode with a ts file to generate a live content.

I run as follows and added a LOOP trace to validate:

python3 x9k3.py -i ../sample.ts -r -o ../out
phosy@DESKTOP-FHL6Q1U:~/DEVEL/x9k3/x9k3-main$ python3 x9k3.py -i ../sample.ts -r -o ../out
LOOP
../out/seg0.ts:   start: 1.480000   end: 4.520000   duration: 3.040000

../out/seg2.ts:   start: 7.560000   end: 10.600000   duration: 3.040000
../out/seg3.ts:   start: 10.600000   end: 13.640000   duration: 3.040000
../out/seg4.ts:   start: 13.640000   end: 16.680000   duration: 3.040000

deleting ../out/seg12.ts
LOOP

The problem is that the segments end when the sample video ends and I don´t see that it starts again. I've observed in the code that the while true loop is working but it seems the threefive decode stops

The sample I used is the following: https://www.dwsamplefiles.com/?dl_id=396

Any ideas? Thank you

As I mentioned on other issues, I open a new one clarifying the behavior I get when trying to use the tool to play on a native player (IOS 15) and the replay mode.

I have an input file that is an MPEG.TS generated with ffmpeg with the following characteristics:

Input #0, mpegts, from '../live.ts':
  Duration: 00:00:48.02, start: 1.458667, bitrate: 1790 kb/s
  Program 1
    Metadata:
      service_name    : Service01
      service_provider: FFmpeg
    Stream #0:0[0x100]: Video: h264 (High) ([27][0][0][0] / 0x001B), yuv420p(progressive), 1280x720, 25 fps, 25 tbr, 90k tbn, 50 tbc
    Stream #0:1[0x101]: Audio: aac (LC) ([15][0][0][0] / 0x000F), 48000 Hz, stereo, fltp, 4 kb/s

I execute x9k3 with the following arguments:

x9k3 -i live.ts -o out -t 6 --replay -c

In a first pass, the playlist is generated correctly, segmenting the file and adding them into the playlist. The number of segments for this input file is 8 (with t=6 seconds, from 0 to 7). The throttling is working correctly. The playlist for the last segment is this:

#EXTM3U
#EXT-X-VERSION:3
#EXT-X-TARGETDURATION:7
#EXT-X-MEDIA-SEQUENCE:3
#EXT-X-DISCONTINUITY-SEQUENCE:4
#EXT-X-X9K3-VERSION:0.2.01
#EXTINF:6.000000,
seg3.ts
#EXTINF:6.000000,
seg4.ts
#EXTINF:7.000000,
seg5.ts
#EXTINF:6.000000,
seg6.ts
#EXTINF:4.960000,
seg7.ts

After the duration of the input file has passed, the tool re-decode the input file to start over again for the replay functionality. Now, current segment will be 8. The generated playlist file is the following:

#EXTM3U
#EXT-X-VERSION:3
#EXT-X-TARGETDURATION:7
#EXT-X-MEDIA-SEQUENCE:8
#EXT-X-DISCONTINUITY-SEQUENCE:4
#EXT-X-X9K3-VERSION:0.2.01
#EXT-X-DISCONTINUITY
#EXTINF:6.000000,
seg8.ts

As you can see, all the previous segments are removed from the playlists, and only the new "first" segment is present in it. This breaks the play of this m3u8 in an HLS player (tested with hls.js and native player). This breaks the buffer status in the player. For this to work safely for players, the playlist for the segment #8 should be like this:

#EXTM3U
#EXT-X-VERSION:3
#EXT-X-TARGETDURATION:7
#EXT-X-MEDIA-SEQUENCE:3
#EXT-X-DISCONTINUITY-SEQUENCE:4
#EXT-X-X9K3-VERSION:0.2.01
#EXTINF:6.000000,
seg4.ts
#EXTINF:7.000000,
seg5.ts
#EXTINF:6.000000,
seg6.ts
#EXTINF:4.960000,
seg7.ts
#EXT-X-DISCONTINUITY
#EXTINF:6.000000,
seg8.ts

It should remove remove seg3.ts from the playlist, and should add a Discontinuity tag (as the PTS in the input file restart to 0 and the player needs to be aware of) and continue the live flow with the segment. This change has been tested to play correctly in hls.js and native IOS 15 player.

Hope it helps.

Hi futzu

FIrst i want to say is Merry christmas and happy new year! and scte35-threefive is amazing projects

i am working on splicing segments to insert cue points.
i use simple example from readme file
x9k3 -i segment11.ts -s sidecar.txt

the segment11.ts is a 6 seconds segment with 25fps and GOP of 25 and ffprobe output for the segment with iframe information
Input #0, mpegts, from segment11.ts:
Duration: 00:00:06.07, start: 66.116444, bitrate: 3159 kb/s
Program 1
Stream #0:0[0x101]: Audio: aac (LC) ([15][0][0][0] / 0x000F), 48000 Hz, stereo, fltp, 99 kb/s
Stream #0:1[0x102]: Video: h264 (High) ([27][0][0][0] / 0x001B), yuv420p(tv, bt709, progressive), 1280x720 [SAR 1:1 DAR 16:9], 25 fps, 25 tbr, 90k tbn`

1:frame,I
26:frame,I
51:frame,I
76:frame,I
101:frame,I
126:frame,I

and inside my sidecar file i have this
68.191111, /DAWAAAAAAAAAP/wBQb+AF2lcAAAYGVbDg==

i want x9k3 to splice this segement into 2 segments with first one 2 seconds and second one 4 seconds
but it always give me 3 segements in 2 seconds duration. any ideas it is possible with x9k3 or am i using tool wrong.

here is the segments and sidecar file
https://github.com/cisiwen/x9k3_help_needed/tree/main

thanks

Winston

When running x9k3 with "replay" x9k3 stops on last segment and does not anymore update index file, or write new segment .ts files.

If I fully understand --replay it should keep "faking" continous live stream with updated index.m3u8 and (?maybe) new created .ts files. Everything seems OK until last segment.

x9k3 started with:
x9k3 -i longb.ts --replay
No sidecar / scte35 injection or anything similar was used.

Used version:

x9k3 --version
0.1.57

After some time (approxy 150 seconds) last index.m3u8 was created:

#EXTM3U
#EXT-X-VERSION:3
#EXT-X-TARGETDURATION:3
#EXT-X-MEDIA-SEQUENCE:27
#EXT-X-DISCONTINUITY-SEQUENCE:0
#EXTINF:5.338,
seg27.ts
#EXTINF:5.339,
seg28.ts
#EXTINF:5.339,
seg29.ts
#EXTINF:5.338,
seg30.ts
#EXTINF:5.339,
seg31.ts

This fill remained static after that - no further changes occured to index.m3u8.

This are last moments of x9k3 (I waited until index.m3u8 stopped changing, then after a few seconds I pressed CTRL-C)

Hello. I try to use x9k3 segmenter but have no success.

First problem - its not create .m3u manifest file.
OS enviroment - Win7. I try to use Pypy3 or Python3, with admin rights - no success. Any suggestion?
Also its possible to select target directory for m3u and ts segments?

Second - it crash after some time with the same error.

Thank you.

Say something.

I am open to suggestions.

Is supported to make HLS with SCTE-35 from TS with audio only (radio station) with x9k3?

I am not sure if the below command is correct or not. My requirement is to insert SCTE35 marker to multi-bitrate livestream content generated from ffmpeg.

When I tried with this x9k3 always generating a index.m3u8 file with single bitrate. I want a master file and that should linked to resolution specific child manifest. Example,

master.m3u8

segment-1.ts
segment-2.ts
segment-n.ts
stream.m3u8
media-2
segment-1.ts
segment-2.ts

Hi Mate,

Looking for your latest development release.

Regard
Gaurav

I tried generate m3u8 from test xaa.ts video with scte35 stream inside, but found no x_cue tags in result:

#EXTM3U
#EXT-X-VERSION:3
#EXT-X-TARGETDURATION:3
#EXT-X-MEDIA-SEQUENCE:0
#EXT-X-DISCONTINUITY-SEQUENCE:0
#EXT-X-X9K3-VERSION:0.1.89
#EXTINF:2.002000,
seg0.ts
#EXTINF:2.002011,
seg1.ts
#EXTINF:2.002000,
...
seg27.ts
#EXTINF:2.002011,
seg28.ts
#EXT-X-ENDLIST

I used bin from Dockerfile with cmd: x9k3 -i /src/xaa.ts --output_dir /results

Also it sometimes inserts wrong negative EXTINF values

#EXTM3U
#EXT-X-VERSION:3
#EXT-X-TARGETDURATION:3
#EXT-X-MEDIA-SEQUENCE:0
#EXT-X-DISCONTINUITY-SEQUENCE:0
#EXT-X-X9K3-VERSION:0.1.89

The hls standard states that:

An SCTE-35 splice out/in pair signaled by a pair of splice_insert()
commands SHOULD be represented by one or more EXT-X-DATERANGE tags
carrying the same ID attribute, which MUST be unique to that splice
out/in pair.

https://datatracker.ietf.org/doc/html/draft-pantos-hls-rfc8216bis#section-4.4.5.1.1

This tool generates that pair with different ids for each scte command.

I'm using x9K3 to insert SCTE 35 data and I'm using index.m3u8 to transmit but it suddenly stops and doesn't continue transmission

OS: Debian 12
Comand: sudo x9k3 -i /usr/share/ffplayout/public/live/stream.m3u8 -s sidecar.txt -l

Hey @futzu I cant tell you how useful your tools are specially this one X9K3.
recently I tried to use standard input stream as input to x9k3 and It is not working,

here is my command :

TS file i downloaded from https://so.slo.me/longb.ts

cat longb.ts | x9k3 -l

output:

No Stream Found.

however with
x9k3 -i longb.ts --live
it is working fine.

I appreciate your response.
Thanks

I've found that the current implementation is always inserting EXT-X-DISCONTINUITY tags in the m3u8 file with the segments when a CUE occurs. When you try to playout the generated playlist, this makes the play to freeze or halt at those points, as the player is trying to resync the play because it is expecting a change in the stream. (this is a guess). I've tested it with hls.js, VLC and native iPhone player with similar results

But if you remove the tags from the playlist, the playout works like a charm with the same segments.

I've not found any documentation that requires that EXT-X-DISCONTINUITY is needed when inserting the CUEs in the playlist. This is needed only when, in the Ad Insertion scenario, the original segments are replaced with a new content that requires to be signalled to the player with the EXT-X-DISCONTINUITY.

I wonder if the usage of EXT-X-DISCONTINUITY could require that the segments generated in those points by the segmenter includes some information that permits to play out that correctly, or just to remove te EXT-X-DISCONTINUITY tags by default.

I have tried below command

import x9k3
x9 = x9k3.X9K3('media-1/segment-0.ts')
x9.run()

Its stuck and I could not find any reason behind this.

Could you please suggest if I am doing this in correct way or not?

Thank You

I am new to SCTE and need help on creating SCTE messages like below. I need to understand what does these string means and how I can create and use with this package.

• /DAxAAAAAAAAAP/wFAUAAABdf+/+zHRtOn4Ae6DOAAAAAAAMAQpDVUVJsZ8xMjEqLYemJQ==
• /DC+AAAAAAAAAP/wBQb+W+M4YgCoAiBDVUVJCW3YD3+fARFEcmF3aW5nRlJJMTE1V0FCQzUBAQIZQ1VFSQlONI9/nwEKVEtSUjE2MDY3QREBAQIxQ1VFSQlw1HB/nwEiUENSMV8xMjEwMjExNDU2V0FCQ0dFTkVSQUxIT1NQSVRBTBABAQI2Q1VFSQlw1HF/3wAAFJlwASJQQ1IxXzEyMTAyMTE0NTZXQUJDR0VORVJBTEhPU1BJVEFMIAEBhgjtJQ==

Note: I have copied these messages from your examples.

I am able to insert them my livestream output using this package piping with ffmpeg.

Any help is highly appriciated.

Thank You

I have 5 ts file such as
test_1.ts
test_2.ts
test_3.ts
test_4.ts

I want to pragmatically parse each ts file but my output should be in one directory and one index.m3u8 should created. It like appending to one file.

Below is the sample code but its not working as currently I don't know how to do this.
import x9k3 for ts in multiple_ts: x9 = x9k3.X9K3(ts) x9.args.output_dir="output/" x9.run()

Thank you

I'm trying to put an m3u8 input, with 4 resolutions but x9k3 won't work in this case I have 1080p, 720p, 540p and 360p and master.m3u8 that goes to 4 resolutions

After adding the -c option to being able to continue a previously generated m3u8, the replay option included this option by default.

IMHO replay is an option that implies the usage of one file to produce a live feed. Not necesarily that means the previous content in the output directory is meaningful.

I would suggest to decouple --replay and -c, so if someone needs it for replay, can add it explicitely

Hi Adrian,

I think because of latest changes there is a bug where If I try to add Cue marker immediately with
below sidecar data it is not working.
printf '0,/DAhAAAAAAAAAP/wEAUAAAAJf78A/gASZvAACQAAAACokv3z\n' > sidecar.txt

Where as if replace 0 with Time that is less than next_start it is working.

I think bug is somewhere here if I am not wrong.

Hello.
x9k3 not show CUE-OUT=YES/CUE-IN=YES messages, only binary decoded SCTE messages.
In version 1.21 we get string like that -
#EXT-X-SCTE35:CUE="/DAgAAAAAAAAAP/wDwUAAAAAf/9+AAAAAAAAAAAAAD4xJP8=",CUE-OUT=YES
In version 1.23 and latest string always show as
#EXT-X-SCTE35:CUE="/DAgAAAAAAAAAP/wDwUAAAAAf/9+AAAAAAAAAAAAAD4xJP8="
I think its related to discontinuity control in your script.

Hi Adrain,
We are using udp feed from playout Engine. i would like to check the if that udp is vaild and can be used with x9k3 for hls creation.

We have tested x9k3 solution for stream coming via elemental and it works fine.whereas udp from playout creates problem while playing.

I am very sure there is problem in udp only. But i tried to meet same parameter tested by ffprobe but issue remains the same.

Any help is Great.
