Sudden crash when watching TV (Teletext / PESDecoder error?) (1 Viewer)

[Dragy]

MediaPortal Version: 1.3.0

Description
This happened for the second time since I use 1.3.0. I have no idea why, the error log says something about teletext buffer.

Steps to Reproduce:
Watch TV (Argus TV?)
Wait

seems to have something to do with the PESDecoder header, but no idea what that means...

According to you 'Steps to Reproduce' i assume you are using Argus TV? And does this problem happen @ random or can you reproduce it every time because debugging would be hard if we'll have to 'wait' for the error to show up.

Yes I'm using Argus TV, but with the MP TV Server.

I can reproduce this every time, but it happens at random.

Need someone with TV part knowledge to look into this. Maybe @michael_t has an idea?

Hello @Dragy

I've seen and fixed problems like this before, but I'm not 100% sure if the problem is in the Argus TV plugin or the MP core.
Probably the underlying cause is that TV Server thinks certain streams contain teletext/subtitle data when they really do not.
Could you please:

• supply *full* log files (need the TV Server log files as well)
• supply a TS dump file (http://wiki.team-mediaportal.com/1_MEDIAPORTAL_1/18_Contribute/4_Development/Debugging/TS_Dumps)
• tell us what channel the problem is seen with

Thanks,
mm
