How does one go about undoing an avformat_seek_file call in libavcodec ?
2 juillet 2020, par John AllardI have an application written around libavcodec that sometimes attempts to seek ahead in a video while performing some work. The call to
avformat_seek_file
can only seek to a keyframe, so sometimes I end up in a situation where it ends up seek backwards from my current position in the decoding routine causing me to have to repeat work. For example, if I'm on frame 150 and I want to seek to frame 200, but the only key frames in the file are on frames 1 and 100, this call will have me seek back to frame 100, meaning I now have to decode 100 frames to get to 200 instead o 50 frames to get to 200 from my original decoding position of frame 150.

Is there a way for me to tell avformat_seek_file to undo its last seek and reset me to my previous location ? Is there some other way for me to "save" my decoding state to undo this wrongful seek manually ?


edit - it should be noted that my videos are always h264 encoded in an mp4 container.

threads : always call thread_finish_setup for intra codecs
22 avril 2013, par Janne Grunauthreads : always call thread_finish_setup for intra codecs
Intra codecs do not need an update_thread_context() function and never
call ff_thread_finish_setup(). They rely on ff_thread_get_buffer()
calling it. So call it even if the get_buffer2 function pointer is
avcodec_default_get_buffer2 and it has not been called before.
