Hi,
I have one question about data stream for mpegts/flv:
If I encoded some private data, such as metadata in PES in some private stream
in mpegts, I will send the private data at the fixed interval. Then, ffmpeg can
probe the unknown stream with unknown codec.
I use the following ffmpeg command, but fali to copy private data. How can I
copy the private stream directly into flv file?
ffmpeg -i input.ts -map 0:2 -c copy -bsf:a aac_adtstoasc -copy_unknown -f data
-f flv output.flv
