when I try ffplay http://64.157.15.135:8040 I got only the audio while when with mplayer I got video and audio
same thing with vlc I got only audio with this error "main decoder error: no suitable decoder module for fourcc `VP62'."

Someone on the videolan chan told me that vlc uses ffmpeg to read vp62 format, so how can I check that ffmpeg is actually supporting vp62 codec ?
