Parse fails for h264 ES file
I've found a proper .h264 ES that fails to parse using mkvmerge
$ mkvmerge -o fail.mkv mkvfail.h264
mkvmerge v8.8.0 ('Wind at my back') 64bit
Fel: The demultiplexer for the file 'mkvfail.h264' failed to initialize:
The file could not be opened for reading, or there was not enough data to parse its headers.
