[confirm] Crash if HDMI signal is lost while playing Live TV (1 Viewer)

[kkozma]

This is very easy to re-produce on a system where the TV is connected to the PC via HDMI. Start playing Live TV and turn your TV off. MP will crash every single time without fail. I do not have videos configured in my MP install but I do have moving pictures set up so I tested the internal player with that. MP does not crash while playing a video, but it hangs indefinitely and I had to stop the task to get out of MP.

This is not the first time I've seen a very similar issue. It goes all the way back to MP 1.0. Tourettes fixed it for me back then by creating a new core.dll which stopped playback in the event that the HDMI signal was lost.

The logs titled with the suffix of DEBUG MODE were created with no plugins installed and should show where mp crashed when I switched inputs. The logs titled with SKIN MODE as a suffix is what happens when playing a video.

Not reproduceable here with nvidia graphics and philips hdtv via hdmi for picture\sound, with playing anything, tv, video or music.

Could this be related in any way read quake2rambo answer as I'm just guessing you may be a ATI user, thats why it would be nice if you fill in the my system and enable it in usercp.

I did fill all that stuff out but I didn't realize it had to be enabled.

I'll do that now, but for the sake of the discussion, this is purely an Intel machine. Core i3 530 Clarkdale for graphics and sound.

I experience the same here!
My girlfriend often goes to bed later than me so I thought she did something wrong, until I noticed that everytime MP had crashed the next morning, a frozen tv frame was showing.
So this post here made me realize that that is the case with me too. When we go to bed we always turn off the tv with the button on the tv (so no juice anymore for my tv). If my amp is still on you can hear the sound thats playing when a piece of hardware is detached.
If MP is still running live tv when turning the tv off, the next morning it's crashed and frozen on a tv frame.

I noticed that both of us are using SAF for TV whereas Ray is using the Microsoft codec... I wonder if that makes a difference? I can't test right now, but I will after work.

The graph in your logs say M$ for video, ffdshow for audio.

Not sure what is happening, but if it only ever happens when TV is turned off, then it may well be hardware\driver related or its windows service, if it has one.

Your mediaportal log just dies whilst disposing graph without shutting down as normal, last thing tverser log shows is

Which I take is the frozen picture seen.

There is no error log and even tvserver error log is empty

I figured it out! It's ffdshow audio causing it. I have mine configured for HD audio passthrough of DD, DTS, TrueHD, DTS MA, etc etc. If I disable that and my HDMI signal is lost, MP behaves as expected in that playback is stopped.

So, I'm pretty sure this won't have much to do with MP itself more than a bug with ffdhsow, although I could be wrong maybe there's a more graceful way of stopping playback or something.

I'm going to load the latest SAF and see if this is something that's been addressed. If not, I'll head over to doom9 and report it there.

No dice on the latest version of SAF...

maybe also report it in the SAF forum section? Maybe they can figureout a workaround
