[FFmpeg-user] Use force_key_frames to obtain keyframes at exactly the same positions as in the input stream?

[Haris Zukanovic]

Hello,
Can I use force_key_frames in some way to produce keyframes (IDR, not 
I-frames) at exactly the same PTS in output streams as they are found in 
the live input stream? Both input and output are h264 and live streaming.

Something analogous to using 2 pass encoding for VOD and in the second 
pass keyframes are inserted exactly where they are recorded in the first 
pass... Is that something like that even theoretically doable for live 
streaming?



thanx
