[FFmpeg-devel] FFMPEG Quantization

[shailender]

Hello,


I am an expert in the JPEG files processing. I am looking for mechanism where i 
can set customised quantization table for different frames. I understand there 
is an option for bitrate in FFMPEG. However, i am exploring  the option to use 
customized quantization table. Is it feasible in FFMPEG


Thanks

[FFmpeg-devel] Adding option B does not work

[shailender Jain]

Hello,


I am trying to ensure that a specific number of B Frames should be used by 
FFMPEG. I am running the following command


ffmpeg -i Rediff.mp4  -vstats_file stats.txt -c:v libx264 -bf 16  -crf 28 
Rediff2.mp4


However, when i look at the stats.txt, i cannot see 16 B-Frames. Is there any 
way this can be done? I want to find a way by which i can enforce if a frame 
will be B-Frame or P-Frame or I-Frame. Is this feasible? If not, then please 
help me identify  the source code where i can update the code


Thanks

Shailender Jain
