Now that I've compiled FFMpeg it seems that isn't working correctly...
Is this something we can help you with ?
Another user (Daniel, CCed) has reported me privately that he built
FFMpeg with cegcc, and that loading it from an MSVC app wasn't
working. My guess is that the cegcc.dll isn't being correctly
initialized. There was a thread about that a few months ago, about someone
loading a cegcc based dll into a MSVC app, and that resolved into a
patch being integrated into cegcc. I can't find that
thread in my archives, but the symptoms were very close. Anyway, with
current mingw32ce from trunk and with the attached
patch I could build ffmpeg with the following options.
../ffmpeg-checkout-2007-01-21/configure \
--enable-mingwce \
--cross-compile \
--cross-prefix=arm-wince-mingw32ce- \
--arch=arm \
--target-os=WinCE \
--disable-static \
--enable-shared
The new math stuff is needed because ffmpeg is calling llrint.
I didn't try building with any plugins enabled. Nuno, Daniel, could you
try this?
I have no idea if it runs or if it runs correctly. I never used FFMpeg
before. Any hints on how to test it?
I think I may take a stab at building VLC with this. Should be a smooth
re-port, since it used to build with
the VLC mingwce toolchain (Looks like the nightly builds for WinCE
stopped a year ago).
Anyway, if this is reported to work, I will clean a bit the errno stuff
(perhaps introduce AV_ENOMEM, etc.) and
post a patch upstream.
Cheers,
Pedro Alves
