Expand description

Finds the minimum H.264 level that can handle the given video parameters based on the constraints defined in H.264 specification Annex A.

§width

the video width in pixels

§height

the video height in pixels

§fps_n

the video frame rate numerator

§fps_d

the video frame rate denominator

§bitrate

the video bitrate in bits per second (0 if unknown)

§max_dec_frame_buffering

the max size of DPB (0 if unknown)

§profile_idc

the H.264 profile idc value (e.g., 66 for Baseline, 77 for Main, 100 for High)

§Returns

the GstH264LevelLimits for the minimum level matching the parameters, or None if no suitable level is found.
