[Ffmpeg-devel] conveting I-frames from mpeg2 into jpeg pictures
Tue Dec 13 13:14:22 CET 2005
I'm developing a tool in which I need to extract I-frames from an mpeg2
video file and convert them into jpeg pictures for further processing. I
have already achieved the extraction of the I-frames, without using
FFMPEG (although I know it's possible), but now i am not able to decode
the extracted frames and save them as jpeg images, using the libavformat
and libavcodec libraries.
I would like to know if there is any tutorial or similar for extracting
the I frames and, specially, for converting those images into jpeg
pictures. If not, I would appreciate any other ideas, solutions or
I'm sure this problem has already being solved by many of you.
ps: I have extracted frames with the 'ffmpeg -i test.mv test%d.jpg'
command without any problem. I just attached this to show that the
FFMPEG libraries in my computer seem to be correctly installed.
