Bitrate per component

[bioleyl]

Hello,

We can easily get the maximum bitrate with the asdcp-info -r options but can we get the max bitrate per color component ?

As the smpte:
For a frame rate of 24 FPS, a 2K distribution shall have a maximum of 1,302,083 bytes per frame
(aggregate of all three color components including headers). Additionally, it shall have a maximum
of 1,041,666 bytes per color component per frame including all relevant tile-part headers.

As I understand, we can test with your tool the overall bitrate but not the "per color". Is that right? Are you planning to add that feature?

Best regards

The number of bytes per component (aka "color") can be parsed from the TLM marker contained in the J2C header. The TLM marker lists the number of bytes per tile part. For 2K files, there is 1 tile-part for each component. For 4K files, there is 1 tile-part for each 2K component and 1 tile-part for each 4K component.
