Andrew,

I'm not sure I have the libx264 thing working - with this option I end up creating an .mp4 that won't load into quicktime. As i understand it from the documentation to bet 264 working I have to replace 4 dll files in the idl /bin directory. I did this - but I'm not sure it is correct.

One issue - replacing these files:

avcodec-53.dll
avformat-53.dll
avutil-51.dll
swscale-2.dll

I searched for windows ffmpeg builds and can find these files - but the 53 and 51 are now really old versions. I used the latest versions (55 I think) but then idl doesn't like them - complains that it can't find avutil-51.dll (because mine is avutil-55.dll). I went back through older builds of ffmpeg and found the 53/51 versions - these were from January 2012. Am I doing this right ? It all seems like a right hack !!

Is there somewhere I can get builds of these .dll files that definitely work ?

Cheers - still plugging away.....

George.
