Comment (by atorp):


 Inside the H264RawVUI struct it's defined:

     uint8_t overscan_info_present_flag;
     uint8_t overscan_appropriate_flag;

 So, to add support for the "--overscan" parameter it's sufficient to mod
 the function "h264_metadata_update_sps()" in the
 "libavcodec/h264_metadata_bsf.c" source.

 I hope some developer will add support for it. As it's the only solution
 to use HARDWARE encoding and set this flag.

 Thank you!
