[Ffmpeg-user] Re: output_example does not create valid MP4 file

I create my mp4 with : ffmpeg to create video stream (mpeg4) ffmpeg to create audio stream (wav) faac to create audio steam (wav -> aac) mp4creator to create a mp4 file with the video and audio streams

It works perfectly on mobile phones, and with VLC, but not with QuickTime.

Isn't it possible to create mp4 files for PSP only using ffmpeg? Doesn't the software http://www.pspvideo9.com/ only use ffmpeg for creating PSP videos? Thanks for any ideas! Lars
