configured ffmpeg(0.6.1) with below command (with x264-snapshot-20101228-2245 snapshot) with Gcc version : gcc (GCC) 4.3.4 20090804 (release)
./configure --enable-shared --disable-static --enable-pthreads --enable-libx264

bash: sudo: command not found
I checked lot of links showing same error but no solution has been provided. Anybody has any clue who already build ffmpeg on cygwin?
Solução
This is fixed in FFmpeg GIT by using av_
prefix for bswap
macros. You should update to the latest git HEAD
.
