I will try rebuilding the ffmpeg dll's from scratch after downloading the code again. Perhaps setting a asm int 3's inside of avcodec dll to see if I can see what is going on.
Thanks for the help. -- Rich From: richard winterton <[email protected]> Date: Thu, Jul 9, 2009 at 5:14 PM Subject: Re: [chromium-dev] Re: Chromium HTML 5 Integration using avcodec.dlls Yes the name of the dll is avcodec-52.dll as you suggested. But one think I did notice is that the build left the other dependent dll's unlabeled such as the avutil-.dll There isn't a version tag from the build that I have. I got the source from the suggested site but perhaps I left out a step or the the ./configure parameters weren't right and the version isn't set up correctly. (as meantioned I did a disabling of mmx to get it to compile). I will rebuild ffmpeg and see if I get the versioning and test the instructions you have set up again. So not to waste alot of your time do you know why the version information didn't get placed in the util dll? If I rename the avutil-.dll to avutil-52.dll Chromium complains it can't find avutil-.dll so I know the avcodec-52.dll is being loaded.
