I could not add a .mov video produced with a phathom 4

When an elevation model is set, the video footprint is not projected correctly. It is still projected on the target elevation plane instead of the DTM.

The map should be automatically centered on either the footprint or the UAV every second.

Use QGIS Standars https://docs.qgis.org/testing/en/docs/developers_guide/codingstandards.html

Save frame with burned annotations(points,lines....)

In some case a video is split in several mpeg or ts files. So it is interesting that the video manager can behave like a playlist and play videos seamlessly one after one.

It can be as simple as an "autoplay" toggle button in the video manager.

TypeError: isinstance expected 2 arguments, got 1

line 612 QgsFmvUtils dst_ds.SetGeoTransform(geotransform)

Using the new geotransform matrix not work GeoreferenceFrame method

I think we should use geotransform.to_affine()

It is more common and clear to display a layer with the axis of view instead of only a frame center point layer.

If the vertical view axix comes near horizon, then don't draw the footprint. Only draw the axis of view.

Can play the sample videos, but does not plot flight path or footprint. Log file error below.

Hi,
This may be related to #19 (comment).
I tried all possible way of installing the plugin: From the manager and via the folders.
With and without installing the dependencies first. Only the first time when I installed from the manager I was asked for my password, but nevertheless every time I try to load the plugin QGIS crashes. I have even reinstalled QGIS completely, but it did not help.
When I start qgis from the terminal an than load the plugin this happens:
➜ ~ qgis lav filters QGIS died on signal 11Could not attach to process. If your uid matches the uid of the target process, check the setting of /proc/sys/kernel/yama/ptrace_scope, or try again as the root user. For more details, see /etc/sysctl.d/10-ptrace.conf ptrace: Vorgang nicht zulässig. No thread selected No stack. gdb returned 0 [1] 17637 abort qgis

I have no idea how to troubleshoot this and would be thankful for any help.

On-the-Fly Raster Mosaicking

Although the installation has improved a lot I think it might be a good idea to create a windows installer

Metadata callback run always in bakground!

for check is simple,not delete the layer when close dialog and we see how the layers continue to be updated

Additional context
Video and data file extracted from Mavic Phantom Pro. I've attached the original

Any assistance would be fantastic, my python knowledge is extremely limited I'm afraid.

Thank you in advance

Buffer size not work in large videos.

For reproduce it:
Open a video
advance 1 or 2 minutes using the slider

And the metadata not show,the buffer has not arrived yet I think.

Use this video for test DJI_0047_MISB_F.mp4 (sample folder)

When a video comes in the video manager, it's location should be written in a specific column. We can use a reverse geocoding service for this.

enable RTP streaming functionality

In particular docx. Please use the standard doc system for QGIS, based on rst and sphinx.
Thanks.

Some VsCam creates videos with 2 data streams, the first one may not contain KLV Data, but second one does.
For those kind of video we may need to check every data stream before we can read the good one.

Actually we read KLV with -map 0:d

We may need to try other data stream with: -map 0:d:0 or 0:d:1 as well.

Possible implementation for streaming in QGIS FMV.
We did some research and tests to support rtp streams, following changes would be necessary for a first implementation.

1. QTMultimedia and FFMPEG need to listen on different ports. Therefore we need a Splitter in front of the stream to separate AV and Data.

                                                                 |-> A+V on port 8889          --> QMediaPlayer 
   

rtp stream [port 8888] -> FFmpeg Splitter |
|->KLV to output stream --> Data Parser

2. The Splitter can be implemented with FFMPEG as follow:
   example: Receive AV+Data on port 8857. Forward AV on 8858 and return KLV to output stream.

ffmpeg -re -i rtp://127.0.0.1:8857
-vcodec copy -acodec copy
-map 0:0 -map 0:1
-f rtp_mpegts "rtp://127.0.0.1:8858"
-map 0:2
-f data -

3. Bind QMediaPlayer to port 8858

4. Read KLV from in Memory Buffer

video recording does not preserve metadata

Hello,
Thanks in advance for your answers:
under win10 64b using Qgis3.4.9 LTR.
Plugin show (finaly) no message, Installation of dependencies show no erreur.
However i still get "not Misb" in status and "Start location not available" when opening uploded files that assumed to be MSIB compliant.

Any ideas ?
Regards

Draw Frame center point on the map.

I have a video recorded with DJI phantom and it has a metadata attached to it. But when I load the video this error pops up. The status shows "Not MISB"

It's so strange but metadata buffer not work with this video samples http://samples.ffmpeg.org/MPEG2/mpegts-klv/
Can you please just look at this issue?

the transformation is not performed correctly on the edges of the video.
