Oliver Woodman f7fb4d4c35 Optimize NAL unit search. ... I'm not really a fan of micro-optimizations, but given this method scans through every H264 frame in the HLS case, it seems worthwhile. The trick here is to examine the first 7 bits of the third byte first. If they're not all 0s, then we know that we haven't found a NAL unit, and also that we wont find one at the next two positions. This allows the loop to increment 3 bytes at a time. Speedup is around 60% on Art according to some ad-hoc benchmarking.		2015-02-12 12:46:58 +00:00
