MPEG TS reader: require more consecutive packets, ignore h.264/h.265 start codes In an earlier commit I introduced a workaround for h.264/h.265 files being mis-detected as MPEG transport streams. That workaround was used when the first bytes in a file were a valid h.264/h.265 start code. Unfortunately this prevents the detection of valid MPEG transport streams if they do indeed contain such a start code. The fix is to remove the aforementioned workaround. Instead mkvmerge now requires 333 KB of consecutive MPEG transport stream headers inside the first 1 MB of the file, which amounts to ~1680 consecutive headers. This reliably prevents the mis-detection as h.264/h.265 and still allows for detection of real transport streams even if they start with a h.264/h.265 start code. 2017-05-10 14:30:57 +00:00			`#!/usr/bin/ruby -w`
