#1933 closed defect (invalid)

Seeking breaks ASS/SSA support

ASS/SSA subtitles work like this:
mencoder inputfile.mkv -o vid.mpeg -nosound -ovc lavc -vf fixpts=fps=60000/1001,ass,fixpts -ass

But as soon as you try to seek to any position, they don't work:
mencoder -ss 1.0 inputfile.mkv -o vid.mpeg -nosound -ovc lavc -vf fixpts=fps=60000/1001,ass,fixpts -ass

ASS/SSA subtitles used to work just by using -ass (without the fixpts stuff) but that was broken over a year ago.
The last version I have seen that had working ASS/SSA support was r30369.
In that version, the following works perfectly:
mencoder -ss 1.0 inputfile.mkv -o vid.mpeg -nosound -ovc lavc -ass

P.S. There was a new version of libass released in May that maybe you missed because it was inactive for a long time:

do -demuxer mkv then
thats pretty much the only change i can think of that broke anything
would be making -demuxer lavf default for mkv...

Hi compn, are you suggesting that adding -demuxer mkv would fix the bug? I tried it and it didn't work, using the following:

mencoder -ss 1.0 inputfile.mkv -o vid.mpeg -nosound -demuxer mkv -ovc lavc -vf
fixpts=fps=60000/1001,ass,fixpts -ass
