Compliant file from video and telemetry

[All4Gis]

Hi

I haven't tried your library, but I wanted to know if it allows you to create a compliant file from video and telemetry.

I develop this project and getting that is my achilles' heel.
https://github.com/All4Gis/QGISFMV
At the end I "simulated" the MISB creation

Thanks and good job

Thanks Fran. Absolutely, that is a use case jmisb was designed to support. I think what you'd want to use is VideoFileOutput- there's an integration test showing how to use it.

Note that we haven't thoroughly tested compliance with any particular tool, at least not yet. @bradh is testing with CMITT and has reported issues #97, #102, and #103, so work still needs to be done. Please report back here if you have questions or can share any findings. Thanks!

Concur. If the integration tests are a problem, I have some generator code that I could clean up a bit and push to github. Its from the integration test code, just does it as standalone.

There is sample data available from MISB, but its not redistributable (also, its old, and some of it is possibly broken). There are two useful samples in https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/issues/642 - one for sync, and a second for async metadata.

I think #97 is an accuracy problem, but a decoder probably won't hit that. There are more CMITT problems in my tests, but I'm not sure if they are real or not yet.

Good news then. About sample data, i have a lot of videos in this folder, is public https://drive.google.com/open?id=1-B2uaW7_cfYZohZYFozrgBhIaztI1MSP
I'll test what it says if it works and try to replicate it in python.

If you are generating files, and want me to test them, feel free to push whatever you want. I can email you back the CMITT HTML output.

@All4Gis is anything further required on this issue?

[All4Gis]

Nope, thanks, you can close it.

Just one last thing, I see that ffmpeg is used, do you have any idea how to do the same as VideoFileOutput but using command line?How create a packet or merge packets etc?From what I understand with ffmpeg, it can't be done

@All4Gis - sorry I missed this question. But I am in the same boat, I have not seen any examples of muxing MISB metadata with the ffmpeg CLI. Doesn't mean that it can't be done, of course.
