[FFmpeg-devel] [PATCH] lavd/lavfi.c: Set time_base for 608 cc to container time_base.

2021-06-20 Thread Thilo Borgmann

Hi,

when transcoding 608 cc, the cc stream frame pts is set to the same value as its 
container frame's pts. However, the time_base is always set to 1/9 (default) 
in the initialization stage. Which causes timing issues when the container 
time_base is actually not 1/9.
