I tried this. I used the following ffprobe line: ffprobe -v quiet -select_streams v -of csv -show_frames -show_entries frame=pict_type,coded_picture_number -read_intervals %+#24 output.m2v > test.txt 1. Here is the order of frames before sorting. I presume this is how they're stored in the stream. I B B P B B P B B P I B B P B B P B B P I B B P 2. Here is the order of frames after sorting on coded_picture_number. I presume this is the order the frames need to be decoded in: I P B B P B B P B B I P B B P B B P B B I P B B When discussing GOP structure, which order is used?
