There should be a scale option too since the matrix encodes that

This duration is equal to the longest duration in all track's tkhd atoms, which
may be comprised of the sum of all edit lists in each track. Empty edit lists
in tracks represent start_time, and the actual media duration is stored in the

c11fb46731 led to a regression whereby the return code for missing

hence not conveyed in the exit code.

Hi.
Over the years, I have promised quite a few enhancement to FFmpeg's API,

(JSON, XML, etc.), a way to exfiltrate data from filters and other
componen
They are already synced generically in update_context_from_thread()
