sei_user_data Insert a string as SEI unregistered user data. Note that some sizes may notīe representable if the chroma is subsampled or the stream is interlaced These values will replace theĬurrent ones if the stream is already cropped. crop_left crop_right crop_top crop_bottom Set the frame cropping offsets in the SPS. The framerate is exactly half the tick rate, but the exact meaning isĭependent on interlacing and the picture structure (see H.264 sectionĮ.2.1 and table E-6). fixed_frame_rate_flag Set whether the stream has fixed framerate - typically this indicates that This is the smallest time unit representable in the stream, and in manyĬases represents the field rate of the stream (double the frame tick_rate Set the tick rate (num_units_in_tick / time_scale) in the VUI parameters. chroma_sample_loc_type Set the chroma sample location in the stream (see H.264 section E.2.1 andįigure E-1). colour_primaries transfer_characteristics matrix_coefficients Set the colour description in the stream (see H.264 section E.2.1 and video_format video_full_range_flag Set the video format in the stream (see H.264 section E.2.1 and tableĮ-2). overscan_appropriate_flag Set whether the stream is suitable for display using overscan or not (see Sample_aspect_ratio Set the sample aspect ratio of the stream in the VUI parameters.
