tandberg 4/5 have large codec delays because of misordered frames, and the delay jumps randomly within the file. We don't preroll well enough to know the correct delay in advance and so at each point where we return a frame too far ahead in the future, we drop the preceeding frames once we get around to decoding them because we've already passed that point in units returned to the application. The correct solution for these would be to increase delay dynamically whenever we encounter a gap until either we're at max-delay, or until we've resolved the gap. almost certainly, max-delay should be settable in user applications so we can disable it for live/low-latency purposes. Q: should we return old frames also? The user may want to reorder himself (although this doesn't make much sense). Fate currently uses -strict 1 as a workaround for these samples, which simply forces codec-delay to 16. This is not the correct solution.

Although FATE can appear green, in fact many of the samples in FATE are not bit-exact.

The following samples are not bit-exact.

H.264

tandberg 4/5 have large codec delays because of misordered frames, and the delay jumps randomly within the file. We don't preroll well enough to know the correct delay in advance and so at each point where we return a frame too far ahead in the future, we drop the preceeding frames once we get around to decoding them because we've already passed that point in units returned to the application. The correct solution for these would be to increase delay dynamically whenever we encounter a gap until either we're at max-delay, or until we've resolved the gap. almost certainly, max-delay should be settable in user applications so we can disable it for live/low-latency purposes. Q: should we return old frames also? The user may want to reorder himself (although this doesn't make much sense). Fate currently uses -strict 1 as a workaround for these samples, which simply forces codec-delay to 16. This is not the correct solution.
