[FFmpeg-user] User data extraction in FFMPEG

[rohit khali]

Hi,

I want to extract raw "user data" for Mpeg2 and H264 streams. Is there any
FFMPEG API which returns the user data as a buffer.
My application will handle "user data" on its own to get information like
EIA-608/708.

My idea was to call this API before calling decode API.

Thanks,
