H264: First 12 frames are grey #43

Closed nschlia closed 4 years ago

nschlia commented 4 years ago

Only with mp4 format the first 12 frames are simply grey, the next 2-3 frames are blurred. Happens with the H264 codec only, other codecs are not affected (mp4 and ts output format).

Obliviously the crf option can be helpful:

Garbled frames are gone. Also the overall quality is much better now.
