ffprobe: Query the container
|
||
|
|
ffprobe -v error -select_streams v:0 -show_entries stream=nb_frames -of default=nokey=1:noprint_wrappers=1 input.mp4
|
||
|
|
This is a fast method.
|
||
|
|
Not all formats (such as Matroska) will report the number of frames resulting in the output of N/A. See the other methods listed below.

ffprobe: Count the number of frames
|
||
|
|
ffprobe -v error -count_frames -select_streams v:0 -show_entries stream=nb_read_frames -of default=nokey=1:noprint_wrappers=1 input.mkv
|
||
|
|
This is a slow method.
|
||
|
|
Add the -skip_frame nokey option to only count key frames.
|
||
|
|
ffmpeg: Count the number of frames
|
||
|
|
If you do not have ffprobe you can use ffmpeg instead:
|
||
|
|
|
||
|
|
ffmpeg -i input.mkv -map 0:v:0 -c copy -f null -
|
||
|
|
This is a somewhat fast method.
|
||
|
|
Refer to frame= near the end of the console output.
|
||
|
|
Add the -discard nokey input option (before -i) to only count key frames.
