-bitexact expects an argument. Use -bitexact 1.
Thank you very much, this was a problem. I created my first PSP video with my own ffmpeg :) But I still wonder why PSP Video 9's ffmpeg.exe understood this parameters with an error. Nevertheless, I still have two questions: 1. When I use the additional configure options "--enable-shared --disable-static" I cannot compile ffmpeg because faac library is not found. When I don't use this options I can compile it?!? My original aim was to create a avformat.dll which helps me creating PSP videos. I am using the configure params: --enable-memalign-hack --enable-mingw32 --prefix=/home --enable-faac --extra-cflags=-Is:/faac/include --extra-ldflags=-Ls:/faac/libfaac/.libs --enable-shared --disable-static When running make I receive the following linker error: s:\system\bin\..\lib\gcc\mingw32\3.4.2\..\..\..\..\mingw32\bin\ld.exe: cannot find -lfaac collect2: ld returned 1 exit status make[1]: *** [avutil.dll] Error 1 make[1]: Leaving directory `/s/ffmpeg/libavutil' make: *** [lib] Error 2 2. I cannot use the ffmpeg option "muxvb 768". ffmpeg.exe tells me: "unrecognized option '-muxvb'" Best regards and thanks again for all your help Lars
