Hello everyone!
First of all I have to say thank U, becouse I have learned everything about videos from this forum.
And the question:
I'm experimenting to create SVCD with SVCD subs and add a text subtitle stream (.sub or .srt) to the CD to be able to watched on my computer. Then just open the mpeg file on the disc with eg. media player and use dvobsub to display the sub from the text file. On the stanalone player the SVCD subs can be played.
The only problem that the subs from the .srt file does not work with the mpeg. I can see them, quality is ok, but it desync!
The SVCD was created from avi:
AVI 23,976 (checked with GSpot)
SVCD created with 29,97 fps. (plays back with 23.976)
original sub works good with the avi, but not with the mpeg, however I cut 2 seconds from the beginning of the sub, such as DVD2SVCD does with the movie.
In the beginning it is OK, but later it is faster than the film progressively.
I have already tried the folowing:
To be sure about the timing of the subs, I adjusted it to the times displayed in the Winsubmux log file (In the DVD2SVCD output library). After this, nothing has changed: progressive desync still appeares.
Checked CPU usage during PBC, it was about 60%, never higher than 70%.
During playback I opened dvobsub menu from the icon, displayed on the taskbar, and found something strange: the mpeg codec window shows the average fps. It was about 23.96 and not 23.976 as in the txt sub. Tried to solve this problem with converting the sub to SubRip (thougt it wont be effected, becouse it does not use frames). Problems remained.
I have no more idea, but suspicious about the mpeg codec(?).
Thanks in advace for any useful ideas
