Processing h264 video/audio stream
1er mars 2024, par DinamoI have separate audio and video streams from a camera that I'm trying to merge to a single file.


Video processing


I have
JVT NAL sequence, H.264 video, main @ L 31data, I had the frames separated and I appended (concat) the frames to one file.

here is the
ffprobeoutput of the data :

the file is being played on vlc, however the video is played like it is on fast forward (every 2 seconds of the video should be about 1 second)


The video should run at 15fps (not sure about that because of the mentioned avi file)


here is
ffprobeoutput of working avi file that contain the video stream :

Input #0, avi, from 't.avi':

I tried this command
ffmpeg -i frame_data.h264 -filter:v fps=15 test.h264but the video is still playing like its on fast forward

pkt_ptsandpkt_dtsare missing in the raw data, maybe that is the reason the video plays on fast forward ? in the working (processed) avipkt_dts,pkt_dts_time,pkt_duration_timeare not missing.
pkt_duration_timeis always 0.033333
pkt_dtsalways jumps by 2 (there is no oddpkt_dts)

Audio processing


I have raw pcm audio of the video :


here is an output of
ffplay -f s16le -ar 16k -ac 1 frame_data2.h264on the raw data



The raw audio does not playing well using this command.


I guessed the parameters (incorrectly ?) from working avi file that contains the pcm data :


Stream #0:1: Audio: pcm_s16le ([1][0][0][0] / 0x0001), 16000 Hz, 1 channels, s16, 256 kb/s


here is frame info from working (processed) avi file

[/FRAME]


I'm trying to understand how should I process the video and the audio so that they will play well (merge them myself with the right av processing to avi/mp4 file)


I also find this extra data that was included for each frame :
I suspect the first column is a sequence number maybe related to dts somehow, second column is a timestamp (milliseconds ?) (maybe you can help me parse it)

Concat video/audio files downloaded from mpd dash manifest

I manage to download all the files (init file + 10 segment files) and put them in an array


File[] files = downloadSegments();

So I have :
[0] -> file-0.m4v (which is the init file)
[1] -> file-1.m4v (1st segment)
... and so on.


My question is how can I concat/append all these files into another file (final_segment.m4v) ?


I looked around a lot and am now using 'com.arthenica:ffmpeg-kit-video:4.5.1-1'
I've last tried :


FFmpegSession session = FFmpegKit.execute("-i file-0.m4v -i file-1.m4v ... -c copy final_segment.m4v");


Is there something I'm missing ?


Also I assume that I'll have to do the same for the audio segments. So I will have 2 files (final_segment.m4v and final_segment.m4a) that I will have to merge/mix together.


If you could help me with some piece of code, that would be great.
