B series has problems keeping time with transcoded files

This is a bit of an odd one, but I think I've found a bit of a pattern.

When I'm watching some files (particularly long transcoded files (DTS to AC3 MKVs)), my Samsung B Series TV seems to not keep time properly. It seems to count the seconds slow, and over the time of a movie it'll end up way behind. i.e. the movie will be at say 1h15m and the TV is displaying progress as 40m.

If I skip backward or forward, it takes me back to the 40 minute mark, then if I scan forward, it's fine.

It gets confused toward the end of the movie and sometimes I have to stop, start and fast forward back to that point.

Samsung PC Share Manager doesn't seem to have these issues. I'm wondering if Serviio is not feeding some form of time correctly to the TV.

This issue also doesn't seem to be apparent on short files that don't need to be transcoded (eg. TV eps)

It's related to FFmpeg and the way it remuxes into mpegts. This only happens with transcoded files.

Thanks Zip, I tried to hunt down to see if there is a bug for this in FFmpeg and/or when they're going to fix it, but I couldn't find anything, do you know if they're going to fix that?

No, last time I checked was this thread: http://www.listware.net/201006/mplayer- ... specs.html

They need to implement m2ts (Bluray mpegts) muxer, hopefully that one will have timestamps correctly defined.

Thanks, yeah, I saw that thread (followed the link from your bug). I did some more searching but couldn't find anything.

Hopefully they implement that soon.

That looks promising, but I'm not sure if it's been added to the code base yet.
