Indirectly related to my previous enquiry... Programatically I want to use FFprobe get a list of the frame numbers (numbers preferred, times if necessary) of keyframes (I frames without the P frames) in a MOV file.
At present I'm using the arguments: -select_streams v -show_frames "M:\ProcessTests\Timecode.mov" -of csv -show_entries frame=pkt_pts_time,pict_type but for this 30-minute video (available at http://www.twentypenguins.co.uk/misc/ffpmeg_tests/Timecode.mov ), that process is taking around 20-30 seconds to provide the lengthy result of approximately 45,000 CSV lines of frame info, which I then parse in my Windows app to find the line indices of every frame with an 'I' at the end. In principle, should there be a faster way to just get the keyframe / I frame numbers (or times), which doesn't require FFprobe to output over 1500 lines of data per minute of video for parsing afterwards?
