WMA2 / libavcodec unhandled exception

Postby neutronscott » 18 Jul 2009 06:05

Log has nothing after libavcodec initialized except unhandled exceptions.

I tried older versions, I tried nightly trunk, no dice. Thought I found solution was browsing in http://www.videolan.org/developers/vlc/NEWS I saw "* New WMA v1/2 fixed point integer decoder", so I disabled all the CPU features (and restarted!). Still errors.

Is there some sample file you could share to us?

anything that uses libavcodec, so it's redundant to post a file. i ran it inside Windows Debugger. seems to be a "fucomi" instruction. it's a VIA C3 Nememiah, which is somewhat a i686 but lacking on some instructions I guess. Does the libavcodec even listen to the CPU features I set in the GUI?

Where can I get a libavcodec_plugin.dll that is compiled without i686 optimizations ?? I tried a FFmpeg avcodec-52.dll renamed and VLC doesn't load it. I not sure if i wanna try to get a build environment setup on this lil PC ...

You have to compile it by yourself or ask someone to do it.

AFAIK libavcodec has two methods (forced and auto runtime detection) but I don't know which one is used in VLC.

That was me asking, I'm trying to setup this build environment now. Kill 2 birds with 1 stone. It's not the CPU detections fault, it's the CPU :)
I wanna fix the a=control in the rtsp server to use relative urls anyway, think it's the cause of my streams not playing on my nokia.
