Hi, what is the fastest possible way to retrieve things like frame type information with ffmpeg api? I would like to write code that does things like - retrieve frame type information (I,B,P) for an MPEG2 stream - retrieve keyframe positions for H.264 (for formats that do not store this info in the container or where no index is implemented in libavformat)
The only thing I found was setting the two AVCodecContext fields skip_idct and skip_loop_filter to AVDISCARD_ALL but the speed gains were only around 5% in my tests, so I would assume there is still a lot of decoding happening. Is there any way to suppress the actual decoding of picture data and just parse e.g. a transport stream and metadata in the bitstream with public API?
