ProRes codec registration

Description

The Apple ProRes video codec, as specified in SMPTE RDD 36.

Codec ID

EncodedPacket data

The packet's data must be a frame() as defined in SMPTE RDD 36.

EncodedPacket type

Since ProRes is intra-frame-only, every packet is a key frame and its type is therefore always 'key'.

• 'ap4x' - ProRes 4444 XQ
• 'ap4h' - ProRes 4444
