#5 Crash on Video Start

[Anonymous]

I'm having exactly the same crash issues as found here: http://www.gossamer-threads.com/lists/mythtv/users/530079?page=last

Unfortunately, I didn't note the last version number that worked before upgrading. All recent versions greater than 0.25.2 have done exactly the same thing. This is using the 32-bit build, on Windows 7 64-bit, Intel Core i5.

How else can I help debug this?

as always a log file of the frontend would be useful. you can use the -l command line parameter.

I would suggest also trying mythavtest - both just by double click (livetv) and by giving it a recording on the command line.

another question: what cpu is this running on and what features does it have? (sse etc)

I found there is also a windows 32bit buld of mythtv build here
https://sourceforge.net/projects/mythtv/
I downloaded mythtv-v0.25.2-3-gf0e2ad8-w32.exe and installed that and it is working, including playback of recordings.
That install also included some plugins, although I do not need them.

This bug (and 3576340) does not appear in x86-0.25-59-gae7ac79. I will try to identify when the bug first appeared and get log files. My CPU is a Core i5 with intel graphics.

I managed to reproduce this, and I think it's just compile problem; gcc is very hard to get right sometimes, especially in cross compile environments. (it is possible the working ones were compiled with gcc 4.5.3 whereas these ones as 4.5.4)

Until I get it sorted, try copying libavformat from a working tarball and it should hopefully keep you going.

Thanks demonioardente. I'll give this a try tonight.

I forgot to mention. I got as far as 0.25.1 and it was still working. I got interupted at that point and haven't gotten back to it.

I had to copy both libmythavformat-52.dll and libmythavcodec-52.dll from 0.25.1 to make this work, but it's running now. The changes to Sourceforge caused the name change. Thanks for your help Xander. Let me know if you want me to test anything else.

So I'm getting the same crash as above.
I installed with no problem at all. The video was looking very dark so I tried messing with the video playback settings to change the rendering engine. After that every time I try to launch a HDTV recording it instantly crashes. If I load a SD recording or a video from the videos section it plays perfectly. I was so excited about this project Finally I could watch my shows in the computer room with out booting into Linux. I tried getting rid of the saved profile in app data but that didn't do any good. Is it possible that my LinHES 7.4 backend is saving my settings somehow? Any questions please ask. I'm stuck.

I never really managed to work out how to fix it, and now that 0.25 is EOL i doubt it will ever get fixed (unless its my toolchain causing it)
