The quicktime spec says "This is a mandatory extension for all uncompressed Y´CbCr data formats”. It doesn’t clarify if the clap atom is recommended or not in mov files that are not “uncompressed Y´CbCr”, though it would make sense if the video container needs to store cropping data. I think constraining the change for only “uncompressed Y´CbCr” would be more cautious though. I’ll revise my patch to include the condition and resubmit. If the patch only impacts “uncompressed Y´CbCr” would any fate updates be needed?
