 Summary of the bug:

 The "libx264" encoder has the parameter to set the overscan flag using "--
 overscan <string>".

 However, when using any of the H.264 HW encoders, all of them forget the
 option to set the overscan flag.

 Futhermore, the "h264_metadata" filter can be used to set (or unset) some
 Video Usability Info parameters of the H.264 bitstream. For example:

 - video_format
 - video_full_range_flag
 - colour_primaries
 - transfer_characteristics
 - matrix_coefficients
 - chroma_sample_loc_type

 But it lacks the "--overscan" flag.
 So I request to include support for this flag in the h264_metadata BSF.

 Thank you!
