Attaching a patch. We don't have a release in tree yet, but it fixes building with -9999. It's not backwards compatible!
Created attachment 199009 [details, diff] For ffmpeg versions above 0.5.
ffmpeg 0.5 pix_fmt.h has: #if LIBAVUTIL_VERSION_INT < (50<<16) #define PIX_FMT_UYVY411 PIX_FMT_UYYVYY411 #define PIX_FMT_RGBA32 PIX_FMT_RGB32 #define PIX_FMT_YUV422 PIX_FMT_YUYV422 #endif so i applied a different, backward compatible patch.
