RTSP VOD will not count playback position

Postby matejdro » 15 Sep 2013 13:48

I have a problem with playing VOD streams from my IPTV provider (streams are RTSP).

Video timer will not go up, it will stay at 00:00 with regular playback. It will only go up when seeking (for example if you seek to 15:00, timer will change to 15:00), but again stay at that time.

That would not be problematic, if it would not break relative seeking with keyboard (Ctrl + Left etc.). That means that for example if you start watching and watch until 15:00 and then want to seek 10 minutes ahead, VLC will seek to 10:00 instead of 25:00, because it would think you are still at 00:00.

I realize problem is probably on server side or at least compatibility between server and VLC, but I can't really affect that because server is not mine (it is from IPTV provider). Is there a way I could solve it client-side? Maybe by somehow tricking VLC into counting time manually on client side instead of trusting server?

I can't really give you any examples (RTSP streams only work inside network of my provider), but I can provide any other info. I pasted logs below, anything else should I include?

Yep, this is a limitation of the TS demuxer.

Probably not, except finishing the code.

I'm seeing the same issue here (in v2.1.0). Wondering if there are any plans to address this?
