Thank you. That works. But I have an question. Will avformat_seek_file()
seek to the exact frame, or merely to the nearest key frame? I'm coding a
video editor and I need to seek to exact frames. My input
format, for now, are raw formats where all frames are stored in
full such as rawuyvy, or raw422P. Will avformat_seek_file()
seek to the exact frame in those raw formats, and will it also
seek to the exact frame if I use it on MPEG-type formats?
Thank you.
