I’ve been watching my Star Trek Voyager DVD rips lately and have noticed an intermittent issue. Occasionally, the screen will flash to a black/blank screen for a fraction of a second and then continue playback as though nothing happened.
The video file I am using is an MKV, generated directly from a DVD rip in MakeMKV, it has not been remuxed or processed in any way. I know Star Trek Voyager/Deep Space Nine do some funky things with frame rates on the DVDs so not sure if it is related to that. DVD rips for other shows that I have watched recently do not seem to do this, which makes me feel like the Star Trek frame rate thing is related.
This occurs no more than one time per episode, usually towards the beginning (within the first few minutes) of playback, and not in every episode. Generally, no dropped/skipped frames are recorded when this occurs. It’s just kind of a minor annoyance but mainly just curious if there is a fix for it.
I’ve tried this on my laptop (Dell Latitude 7520 w/ i7-1185G7) & my media PC (Intel NUC13ANHi7). Both have integrated Intel graphics. I have included details for both devices below.
I have included a debug log for playback of a file that exhibits the issue on my laptop (stopping playback & exiting Kodi shortly after the issue occurs). I believe the issue is the following: CRenderManager initially starts the playback detecting a 29.97 frame rate (at 2024-08-28 13:19:33.789 in debug log) and plays at that frame rate. After a while (2024-08-28 13:20:57.377), it decides the frame rate is 59.94 and switches to that. When the switch occurs is when the screen is blank for a fraction of a second. It then keeps that frame rate for the remainder of the file.
