Frame by frame skipping

Windows XP SP2, Win7 SP1, VLC v2.01. I've had a long-time problem using the frame by frame control playing FLV videos. In one example, I can stop the video and start using the frame-by-frame button. After every click of the button, the player advances one frame as expected. However, after frame 18, it then takes two clicks to advance a single frame. And then after several more clicks it will then take two or three clicks to advance a single frame. Sometimes it will eventually lockup and I will have to use TaskManager to kill the program. Please note that the video itself does not repeat the same frame twice. It is just that the player is not advancing to the next frame. If it doesn't lockup, I can click play to resume. The audio continues, but it takes a couple of seconds to start the video, and it has also skipped many frames before it plays. If I try different FLV files, it may vary in the number of frames before it starts skipping, but I have not found one that doesn't do it eventually. It doesn't matter which version of Windows I use either.

Jimeagle, do you have the problem just with .flv files, or with other video files too? Are you sure your .flv files are "clean" (are complete, did not suffer drops when downloading...)? If you need to navigate into video files, have you considered first converting them into a more user-friendly video format, for example MPEG2, using for example FormatFactory that produces good MPEG2 files repairing most download glitches, and then return into VLC to do what you have to do? Just asking and suggesting.

For myself, with VLC 2.0.0 under WinXP SP3, I have not experienced this very problem since I don't use .flv files. But I completely agree that frame-by-frame navigation in VLC is an issue. One of VLC's severe lack of ergonomy is the impossibility to navigate back-and-forth frame by frame in a video file.

Frame by frame will get stuck with certain files. That is a bug and most likely one of those which won't be fixed anytime soon.

Thanks for the reply. The skipping happens with all .flv files, and with the same pattern no matter where it starts in the video. The suspect problem seems to point to the program, not the data file.

Thanks,
