Last October, kernrj and I commited a series of patches to add a53cc support to the videotoolbox encoder.
In using that feature over the past few months, I've discovered that the generated streams can sometimes contain random/intermittent errors. This only appears to occur on some Macs and not others. These corrupted files cause errors when used with any of Apple's decoders, including Safari, Quicktime, and mediastreamvalidator. The file can be decoded with ffmpeg, although it prints out the following error when encountering the corruption: [NULL @ 0x7fbcce800600] sps_id 32 out of range [h264 @ 0x7fbcd0000000] sps_id 32 out of range Here are two sequential sample segments generated by the videotoolbox encoder (when used with -f hls). They were generated one after the other from the same source; the first is fine, but the second contains the corruption. https://s3.amazonaws.com/tmm1/stream57.ts https://s3.amazonaws.com/tmm1/stream58.ts I'd like to fix this bug, but have been stuck trying to narrow it down. Hoping someone can point me in the right direction.
