Use ffmpeg and ffprobe to calculate frames

1. Download the bin files directly.

http://ftrack.rtd.ftrack.com/en/3.5.0/administering/managing_local_installation/configuring_ffmpeg.html

 

 $ curl -O https://johnvansickle.com/ffmpeg/releases/ffmpeg-release-64bit-static.tar.xz

 $ tar -xf ffmpeg-release-64bit-static.tar.xz

 

2. calcute frames using ffprobe

https://stackoverflow.com/questions/19642736/count-frames-in-h-264-bitstream

 

$ ffprobe -show_streams -count_frames -pretty filename

You will find in the output:

• nb_read_frames=....

 

3. And for the fps, as I heard that ffprobe may report some error for the fps, try a simple ffmpeg -icommand.

ffmpeg -i filename 2>&1 | sed -n "s/.*, \(.*\) fps.*/\1/p"
