qtmux: Don't write Sync Sample Atom for ProRes
Last modified: 2017-01-16 17:29:50 UTC
Created attachment 343559 [details] [review] qtmux: Don't write Sync Sample Atom for ProRes 'sync' should only be true for I-frame codecs, so set it to false when muxing ProRes.
But ProRes is I-frame-only, so every buffer would be sync=true? Or am I missing something here? You could omit the flag completely from the sample in theory, by storing that information in the default sample flags in one of the other boxes.
Ups, comment was wrong. Other way round: sync should be false for I-frame codecs and true for Long-GOP. Same is done for other codecs, like jpeg or dv.
