[FFmpeg-devel] Skip Frame in MJPEG video

After some time, I haven't found anything concerning skipping frame for MJPEG in libavformat directory.
I instead found a function called 'find_frame_end' in libavcodec/mjpeg* but I don't find a link between this function and the way frames are dropped / skipped.
I'm looking for the part that actually skip bytes from input file.
