Bug #1313
Problem skipping/advancing on TS recording
0%
Description
Hi there,
I am now using git 3.3.16~gaa5c84e on a QNAP NAS.
Everynow and then a successful TS recording will play from start to finish in XBMC, but will bail out from playback when you click "skip ahead" or "advance". I have experienced this with the earlier TVH TS work (ericV), but I never really got to the bottom of it. The file documented below ill play fine from start to finish if I dont skip ahead.
I'm not sure if this is an XBMC playback of TS bug, or if there is something wrong with the TS output file from TVHeadend. Hopefully someone who knows the inside of TVHeadend can have a look?
The log at crash for XBMC is here (line 201, time slice 21:16:22 is where i clicked to skip ahead)

The file recorded has these properties in mediainfo (it recorded successfully by TVHeadend)

I'm going to go out on a limb and say the problem is the client. TVH essentially dumps the stream as it receives it (there is a bit more to it than that, but not a lot).
But one thing I would like to check, are you playing back via the PVR (HTTP) interface or are you playing the file by some other means, local disk, NFS/SMB share etc..
If you've not tried the later then please try that first, if that works then it could indicate an issue with the TVH HTTP interface rather than the file or client.

Wow, that was quick.... 
I am playing the file over NFS, and I just tried it over PVR/HTTP and it crached in a similar manner.
So, am i best to log an issue at XBMC for this?

Yeah I would say that if the combination of file+client doesn't work (without TVH in the loop) then its a bug in XBMC.
TS is supposed to be good for skipping etc.. because it doesn't require a file header (per se) and therefore should work well for things like broadcast where data might go missing.
It's not impossible that TVH has done something wrong in the file (like cocked up PMT/PAT maybe?) however it seems unlikely and I don't think XBMC should crash!
If XBMC guys say the file is crap then feel free to re-submit.
