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

[Kaijun Tang]

I have looked at the source code, it provides like ftyp header for packetized 
h264. I have not seen nal, sps and pps headers for writing streams.

 Kind Regards


Kai

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

   built on Dec  9 2010 15:18:49 with gcc 4.4.5 20101112 (Red Hat 4.4.5-2)
  configuration: 
  libavutil     50.15. 1 / 50.15. 1

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,
