[FFmpeg-user] c:v copy - output file is empty, nothing was encoded

[Peter Trompeter]

hi all,

i've been trying to solve a strange problem but i'm not really getting anywhere, so i'm hoping to find an expert here ...
basic situation is i have a raw h264 encoded video and want to mux it into an mp4 container. no audio. no re-encoding.

so i do: ffmpeg -i snippet.h264 -r 25 -c:v copy snippet.mp4

however, this does not seem to work. error message: Output file is empty, nothing was encoded

what am I doing wrong?

sample file can be found at: http://s000.tinyupload.com/?file_id=78774328066008732903

thanks
peter
