MediaPlayer crashes when seeking

Description (last modified by )
When seeking a video file which contains an audio track encoded with Mpeg 1 Layer 3, mediaplayer crashes. The correct way to reproduce is to click on the slider bar, keep the mouse button pressed, and move the mouse. It crashes 100% of the times. If just clicking on the slider once, it doesn't crash, and seeks correctly. I'll provide a backtrace soon. This is in hrev32060, gcc4 hybrid.

I think there is something in the Audio Out Control of MediaPlayer that might be corrupting memory. I have a number of different media files that crash in various places but the common factor all seems to be the Audio Out Control is the thread that crashes.

Seems to be fixed. At least, I can't reproduce this anymore. Will recheck with other files before closing, though.

jackburton: Do you mean since my round of fixes during the BeGeistert Coding Sprint? Or something else?

I've tried with other files, and unfortunately it still crashes.

Can I have an example file please.
And what revision are you running, I checked in a small fix for mp3_decoder recently that might have helped.

The MP3Decoder has code to "resync" itself after a seek. If the file plays through without seeking, then the error is almost guaranteed to be in the resyncing code inside the MP3Decoder.

The MP3 decoder has been disabled in favor of the FFmpeg plugin's support for MP3. So far I have not seen a single seeking crash with MP3 streams anymore.
