Hi,
I build dvbcut-cvs-14 against current ffmpeg sources.
When re-encoding, I always get the warning:
"rc buffer underflow".
I believe this is due to the AVContext's rc_initial_buffer_occupancy
parameter being uninitialized.
In the patch below, it is initialized like in ffmpeg.c,
with this the warning goes away (and in fact recoded pictures
differ slightly).
Regards,
Wolfram.
