Hi there
For a long time I have had the feeling that DVB-T subtitles timing in our broadcasts here in Denmark were off, when using MediaPortal. When I compare a broadcast shown on our "normal" Sony DVB-T TV, the subtitle timing is way better than in MediaPortal.
There are actually two problems:
1. Some of our H.264 broadcasts (channel: DR HD) show subtitles too early and too short
2. On one of our MPEG2 broadcasts (channel TV2), the subtitles "hangs" until a new set is shown. <-- This is a minor problem.
I have uploaded two samples from DR HD to the MediaPortal FTP-server, one where the timing is fine (Imposter 60 MB.ts) and one where it is to early (Echelon Conspiracy 60 MB.ts).
The files are here:
http://cm3.dk/dvbsubs/
The recording plays fine in VLC Media Player, when I enable subtitles (DVB Subtitles - [Dansk]) they arrive at perfect timing and stays as long as they should.
Please ignore the "bad data" or "bad signal" thing in the beginning, my recording hard-drive had to spin up from sleep, so MediaPortal got stuck for a few seconds.
I have also attached debug-logs from playing both samples in MediaPortal. First I played "Imposter" and then "Echelon Conspiracy".
I tested out building my own DVBSub filter from the repository. If I set m_currentTimeCompensation = 0; (in DVBSub.cpp ~ line 321) the recordings with early subtitles works fine. The side-effect is that the good ones suddenly have to late subtitles.
My theory is that the delay is either wrong from TSReader (audioPin.cpp?) or that there is a timing issue in the subtitle filter itself.
Even if you don't use TV with your MediaPortal installation, you can test the recordings by putting them in your "Videos" folder. TS-files will play with DVB-Subtitles etc. if you enable them in MediaPortal Configuration.
Any help is appreciated!
I would also like to hear from Danish DVB-T users that regularly uses subtitles and their experience with them.
EDIT: I added one more recording from 2 days ago with same symptoms (early subs). I put the files on my own server because the TS-Dump server seems to be having trouble with my files (they cannot be downloaded again).
