I have just started experimenting with hello_video example, and I would like to know how to properly demux input file
with a ffmpeg command line tool.
I tried to extract video stream from a MOV container (Big Bucks Bunny, 1080p, H.264 MOV) using:
ffmpeg -i big_buck_bunny_1080p_h264.mov -an -sn -vcodec copy bbb.h264
Unfortunately, the output file is not playable with hello_video (results in black display, but the file is read without an error).
