mpeg2_metadata

Modify metadata embedded in an MPEG-2 stream.

display_aspect_ratio

Set the display aspect ratio in the stream.

The following fixed values are supported:

4/3

16/9

221/100

Any other value will result in square pixels being signalled instead (see H.262 section 6.3.3 and table 6-3).

frame_rate

Set the frame rate in the stream. This is constructed from a table of known values combined with a small multiplier and divisor - if the supplied value is not exactly representable, the nearest representable value will be used instead (see H.262 section 6.3.3 and table 6-4).

video_format

Set the video format in the stream (see H.262 section 6.3.6 and table 6-6).

colour_primaries

transfer_characteristics

matrix_coefficients

Set the colour description in the stream (see H.262 section 6.3.6 and tables 6-7, 6-8 and 6-9).
