[FFmpeg-user] how to extract h264 nal bitstream into a file from h264 quicktime file?

Hi Kai,

Use -h to get full help or, even better, run 'man ffmpeg'

I have tried that for both .mov and video only. But I got


Unable to find a suitable output format for 'of.264', here is my ffmpeg info

Here is how I did it:

http://www.cardinalpeak.com/blog/?p=878

ffmpeg.exe -i Old\ Faithful.mp4 -vcodec copy -vbsf h264_mp4toannexb -an of.h264
I have also done this with .mov containers, which I assume is what you mean by a 


quicktime file.


Regards,
Ben

I have tried -vbsf h264_mp4toannexb or -f rawvideo. These options don't work.

Thanks,
