I have a Windows based C# application that uses the LeadTools Multimedia SDK (DirectShow based) to position a video to individual frames as requested by the user. I am now porting the program's logic to a QT 5.5.1 application in OSX El Capitan (10.11.4) and have not found a multimedia library that allows me to reliably position to individual frame #'s. I have tried QMediaPlayer, QtVLC, gStreamer, and QtAV. None of them appear to allow finite positioning while the video is paused if the position is outside of the current 'video buffer'. I'm looking for a library that would allow, for instance, opening a video file and then stepping through it frame by frame with the ability to start playing the video at any given frame. Anyone have any thoughts on where I might find such a library?
