opening blu-ray playlists - audio delay #70

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
when opening blu-ray playlists containing of more than 1 main .m2ts file (e.g. 
a playlist of a documentary which plays all single parts after another), there 
seems to be an issue with audio delay, as soon as one part ends and the next 
one begins. (gaps?).

this doesn't happen when you skip over this spot and jump to a position when 
the next part has already begun.

the audio of the next part seems to start to early, before the video of the 
former part finished playing.

(note: this was not tested with a real seamless branching movie, but a 
documentary. there might also be problems with those movies in which the audio 
really needs to be on spot in regards to sync)

Real seamless branching movies work perfectly.
It must be something special about chaining multiple episodes together.

the problem seems to be that this there is one of those small .m2ts files of 
which eac3to for example cannot detect the source format, that follows after 
each main movie file, before the next one begins. (so its main file, small 
file, main file, small file, main file, small file for the complete playlist)

in case of normal seamless branching movies, all m2ts files which belong to the 
main movie of course include video and audio, thats why I guess there are no 
problems

the only task this small file has is to prolong the time the BBC logo at the 
end of each episode is shown. thats why it doesnt seem to include no 
video/audio (or only such eac3to & mediainfo cannot detect) and thats why there 
seems to be a problem with video and audio behaving differently: the video of 
the next main m2ts file waits for the duration of the small file to be over, 
but audio starts at once --> delay
