Good morning to all,
I'm new to ffmpeg and I need help.
I want to extract only the I-frames from a MPEG2-TS file and save them as
PNG or JPEG.
I'm using the following command:
ffmpeg -i test.mpg -intra -t 10 -r 1 -f image2 img-%03d.jpg
Although I use "-intra" (which is for the encoding step), I don't know if
the frames I extract are intra ora not. DO you have such information?
Also, I need to extract to associate the timestamp to the frames; the idea
is to save each frame as TIMESTAMP.jpg
Can somebody help me??
Thank you in advance!
