at least ffplay (in ffmpeg stuff) supports raw h264 files, and I've played some of them (I encoded a raw h264 file with x264 and then played it with ffplay, and it's ok)



>> In addition: in the produced raw file, I don't see any nal marker (00 00 00 01), even if H264FileSink seems to insert them (I made a small debug.). Why?

I confirm the bug.
addData() with the nal marker passed as parameter is called, but strangely there're not nal markers in the resulting file (or files, if -m option is used).
