Thanks. Please, can you provide debug log from Frodo 12.3 with same movie? Just for compare.

I have only one idea. Problem is what dxva decoder initiated twice and for radeon HD it's fatal behavior. Why? I don't know. Need summon @FernetMenta or/and @elupus to this thread.

Beta 4 still broken.

Doing some debugging of this, it looks like the issue is somewhere in ffmpeg, and the DVXA implementation of getformat. IE this code:
https://github.com/xbmc/xbmc/blob/master/xbmc/cores/dvdplayer/DVDCodecs/Video/DVDVideoCodecFFmpeg.cpp#L98
It appears that GetFormat is called twice from ffmpeg. I'm not sure where or why, as the windows build of ffmpeg doesn't have symbols in a useful form for visual studio.
I suspect something like this:
https://github.com/cg110/xbmc/commit/315032321ab805d3692fff04811077c49271f382
might workaround the issue, as it'll close the current dxva decoder before asking for another one. However, I've no idea how to make a release build for others to try, as I tend to do debug builds.

I will build windows version with your workaround. It take a while.
RE: DXVA problems in Gotham Beta 1/2/3 with Radeon HD3400? - nille02 - 2014-04-21
Sounds plausible since the HD3XXX and below cards can only decode one stream at the same time.

nille02, please try this build https://drive.google.com/file/d/0B42OdYa12czTVWJZOWNwRVFJS3M/edit
If it also doesn't work correctly, please provide a debug log.

Thank you very much, it works.

Awesome! I'll create a PR at github.com.
RE: DXVA problems in Gotham Beta 1/2/3 with Radeon HD3400? - cg110 - 2014-04-21
Note that there's also a follow up change I found by making opendecoder randomly fail:
https://github.com/cg110/xbmc/commit/2f7984da53e09cba3fd1106b144bc8300f11da9b
It's the likely cause of the access violations in the debug logs.
If opendecoder works once, then avctx has the hw hooks set, if subsequent calls fail the hooks are left in place, but the hardware context is null, and so it causes access violations.

@cg110 @afedchin i want to thank you both for your patches and everyone else who helped. I have now Build my own Beta 4 with the Patch from cg110's https://github.com/cg110/xbmc/commit/6829556b35762b5df366d0ce5fd7b4065fa85843 . This runs very well on my HD3200, HD4200, Mobility HD 3650, HD 3850,HD5770, HD7850, Intel HD 2500 and Nvidia GTX760 (i don't have more Cards to test, only a ATI xpress 200m, and a S3 Savage DDR but both don't have a video decoder and the last one has is not xbmc capable because of opengl 1.4).
This is my Build with the Gotham Final Source and cg110's Patch

@nille02, can you try this build of xbmc.exe https://drive.google.com/file/d/0B42OdYa12czTZlFvcjdzWWM5a3c/edit with an other small workaround for your issue. just replace XBMC.exe from beta4 to this new one.
