Using Kodi 14.2 (Helix) for Live TV via cable system. Some channels contain content that causes the hardware de-interlacer to apparently drop frames. Kodi counts skipped frames, and we can see that count rapidly increasing when this content is encountered. I've discussed this in the Kodi forums here: http://forum.kodi.tv/showthread.php?tid=231955&pid=2052702#pid2052702 - Kodi devs seem to think this is caused by the stream having mixed progressive & interlaced - causing switching back and forth. I've reproduced the issue via gstreamer using a capture of the live tv stream (also used for testing in Kodi): gst-launch-1.0 filesrc -v location=file.ts ! decodebin ! vaapipostproc deinterlace-method=3 ! vaapisink Playback with this command is really jumpy. The effect looks almost like skipping back & forward in time. I will attempt to attach log files showing the console output from playing two different samples with the above command. The output seems to show some "interleaved" and "progressive" references. The same file played with the following command plays smoothly, though of course with the interlaced lines: gst-launch-1.0 filesrc -v location=test-usa-svu-1.ts ! decodebin ! vaapisink I will attempt to attach the test samples as well, if allowed. Info on the system: Model: Intel NUC D54250WYK (Haswell) Kernel: 4.0.7 Mesa: 10.6.2 libva: 1.6.0

Video samples will be too large to attach.

I failed to access the links you provided.
Ah, sorry about that. Something's strange as the links seem to still work for me. Let's try Google Drive instead then. Here's a link to a folder where I can drop any other samples you may want to see. https://drive.google.com/folderview?id=0B_bzwvu0gyw3fjF4NnQxeGFoOWtrQVlUdXJsZGhVVUE0alRhR1hqbVlFaXEyT09JVHJVem8&usp=sharing
Sorry for slow response, Do you still experience this issue?
Well, last time I checked, it was still happening. However, over the course of time since reporting that, I've since switched over to running Windows on my TV boxes. I've also moved and am on a different cable system. As such, I'm not willing to switch back for testing at this time.
I closed it as won't fix MCDI/MADI for mixed interlaced/progressive stream. Please feel free to reopen this bug or file a new bug if you have interest in the future.
