It appears the exact definition of "keyframe" or "successful decoding" is codec- and application-specific. Since the only thing the nut format does with keyframes is to optimize seeking to them, and since it does _not_ specify how codecs or applications should behave when decoding, I think it would be good idea if the definition doesn't rely on the meaning of "successful decoding". In other words, a muxer uses a keyframe when it wants a demuxer to be able to seek to it, but the determination of whether a frame can be a keyframe is left up to the encoder/muxer. Regards, Clemens
