Hello John,

Sorry I am not talking about the command line option of qscale in ffmpeg.

Please refer the below link about the H264Context Struct Reference.

https://www.ffmpeg.org/doxygen/2.4/s...64Context.html

This structure has a variable qscale and below link is about Picture Structure which has qscale_table.

https://www.ffmpeg.org/doxygen/3.1/structPicture.html

These variables were filled while decoding each pixel of a macro block (in fill_filter_caches method of h264.c )
