VLC 3.0.4 video playback errors for some MKV x265 HEVC files
Posted: 20 Oct 2018 21:02
I tried these suggestions before reporting this issue: reset my preferences, retry with latest nightly build of 3.0.5 and 4.0.0, and search this forum for duplicate posts. The issue still happens and I did not find a duplicate so I am posting.
VLC 3.0.4 is working great for me for all content, except one group of 10 MKV files. The 10 files are all encoded the same, it is a 10 episode season of a show with each file 40-50 minutes in length. During playback, VLC video playback fails after 5-15 minutes but audio keeps working. Playback of all the files triggers one of a few different VLC playback failures. The content plays perfectly fine in latest Windows Media Player on latest Windows 10 with all updates installed. Here is the codec info displayed by VLC for the MKV files. The different types of VLC video errors are listed below.
Here are some examples of the types of VLC errors I get during playback of these 10 MKV files:
- blank video but audio keeps playing
- half of the video goes black (lower left half triangle), but video (upper right half triangle) keeps playing and audio keeps playing
- VLC window freezes
- VLC window closed, but background process remains and I cannot open a new VLC window until I kill the background process
- Windows freezes with blank, solid color screen and becomes unresponsive
The failures do not happen at the same timestamps in each video file, it is somewhat random. If I kill VLC and restart the video where it froze, playback is ok again until the next random failure 5-15 minutes further along. I keep having to close and reopen VLC multiple times to get through each 40-50 minute video. Sometimes I have to use Task Manager to kill a leftover background VLC process. I guess I could watch perfectly fine in WMP at x1.00 speed, but VLC has spoiled me with x2.00 - x2.50 playback speeds. For the two times Windows completely froze and became unresponsive, I had to hard reboot my PC.
I noticed something which may or may not be related. There is a "Preload MKV files in the same directory" setting in VLC settings and it is enabled by default. When enabled, VLC video playback errors would happen about every 5-10 minutes. After I unchecked the MKV preload option, video playback lasted longer at 10-15 minutes before I experienced another video playback failure. I am not sure if this helps but I thought I would mention it.
I enabled debug logging in VLC 3.0.4 before I started playing one of the files from its start. I can attach a zip of the 94KB log file if the forum allows it; the zip size is only 8MB. In case I cannot attach a file, here is a sample of the error messages I see including a few debug messages around the same times.
