Title: Bug report - Video Splitter 3.6 version - Jump to keyframes not correct
Post by: Fred101 on January 22, 2013, 02:52:08 AM
When using avc format in mkv container and jumping forward and backward keyframes, splitter simply doesn't jump to same frames.
Jumping forward seems correct, it jumps to scene change where keyframe should be. Backwards it jumps incorrectly (it jumps at 1 sec intervals for me).
In avc in mp4 container I haven't yet noticed this bug.

And if I might add, your resize filter, whatever u use, is not really good. Frame in full screen is really pixelated compared to frame in MPC (especially seen around the edges). Ability to take screenshot in actual video resolution is nice since ability to zoom to actual frame size is not implemented, but at least we now have a way to take screenshot while avoiding splitter's resize filter. And unfortunately, even in this version I can't find a way to avoid elecard avc decoder. It simply doesn't accept ffdshow video decoder, althought it's clear that ffdshow can decode avc format. At least in MPC it does. And in splitter when show preffered codecs for current file's format is checked, my list (which has ffdshow in it) becomes empty and if I try to force ffdshow as preffered decoder, nothing changes.

All the best, great program.

Could you please upload for us this file to any file host service (e.g. filedropper.com (http://filedropper.com) or dropbox.com (http://dropbox.com))?

Please specify also on what time positions you navigate.

Yes, unfortunately for AVC video can be used at the present time only Elecard AVC decoder.

Here is a short clip trimmed with Video Splitter 3.6 version and 2 project files with marks on keyframes as splitter reads them. 1st project when going to next k-frame(it reads it correctly on scene change), 2nd when going to previous k-frame(it jumps in intervals of 25 frames and not to keyframes from what I can see). One other bug I noticed in this clip is that sometimes when I'm jumping to previous k-frame just before I would reach the very beginning, the start of the clip, the splitter would freeze on me.

Hello Fred101,

Thank you a lot for files and description.

Both problems were reproduced (wrong positioning on the previous K-frame and freezing).

We will post here as soon as there will be new update with fixed bugs.

Thank you for your patience.

Hello Fred101,

Bug with wrong positioning and freezing while navigation to the next/previous K-frame was fixed in the beta version:
