How to preserve data stream with none codec from a video while compressing it using ffmpeg ?
5 octobre 2022, par rj_7I'm using the following command to compress a video of size 1.5GB to 80 MB.


ffmpeg -i input.mp4 -copy_unknown -map_metadata 0 -c copy -c:v h264 -b:v 5000k -c:a aac -b:a 48k -map 0:v -map 0:a -map 0:d output.mp4


The problem I'm facing is - it doesn't copy the data stream to the output video even when I explicitly mention it via mapping. If I don't use the -map options for each kind of stream, it just process the video and audio as expected. But I also want the data stream in my output video.


The logs for the above command are -

I've also tried mapping the streams via number, that doesn't work either (shows same logs as above).

So, essentially my question is - How to preserve data stream (packed) with none codec from a video while compressing it using ffmpeg ?

Playback FFmpeg stream through UDP
11 juillet 2020, par Andrew RaleighI'm using the following command to send ffmpeg data :


./ffmpeg -i "" -pix_fmt yuv420p -tune zerolatency -preset ultrafast -f mpegts udp://127.0.0.1:23000

I then transmit and receive it to another computer through the srt protocol, and read it back on the end-point.


I play back with
.\ffplay.exe -i udp://127.0.0.1:23000 -loglevel 40and don't see a video. I can see data coming in from WireShark though. This is the log output :

FFPlay and FFProbe both output the above. Usually FFPlay would show the video playing back, but in this case I get nothing. Any thoughts as to why ?
