i get a blocky picture from timestamp ~119 minutes on with a mkv
file(one videostream mpeg 2; original from dvd, one audiostream
orignal ac3). filesize = 5,5 GB!
in the irc they told me to report this bug to this emailadress.
what i did: (all on windows XP SP2)
1) ripped the dvd "Star Wars: Episode III - Revenge of the Sith"
wiht dvd-decryptor to my harddisc. (7 vobs) it is s german pal-dvd.
2) used dgmpgdec146 to get ac3 and m2v file (save project and demux
video), did this also with Vobedit06.
3) merged audio and video (wihtout rekrompression) with MKVtoolnix
(mkvtoolnix-unicode-1.6.5-setup.exe) to an mkv file.
4) when i play it wiht vlc or media player classik, or via
MatroskaSplitter.exe in a regular media player the video gets
blocky from minute 119 on. if i play the original videofile only
(the *,m2v) it is not blocky!
if i cut out 5 seconds of the video behind timesamp 119 min, it
stays blocky on playback (my mediaplayer plays it, vlc doesn't play
if i make a mkv without audio the prbolem stays the same.
i have cut out a 5mb chunk that shows the error, i can mail it if
i asume that mkv has a problem with large mpeg2 streams.
