I was able to rerender the videos and perform the test again. There seems to be no change, so the video resolution is not the cause of the crash It's possible that the two VLC instances are interfering in some when then using VDPAU. It's also possible that something about Xlib is causing the crash. ...

Hi all, Sorry it took me a while to return to this issue. I was able to reproduce the error with VLC version 3.0.8 Vetinari (revision 3.0.8-0-gf350b6b5a7). Is this a version that is still supported? Regardless, let me know if you have other thoughts on how to debug the issue. We have tested it on se...

Ah, I'll try to reproduce the issue with the latest version. Thanks for the tip.

Just realized I forgot to post other system details.

VLC Version: 3.0.3 Vetinari (revision 3.0.3-1-0-gc2bb759264)
System: Ubuntu 18.04.1 64 bit w/AMD Ryzen 3 2200g and GeForce GTX1050 Ti

Let me know if there's any other useful information I can gather,

Thanks unidan! Sorry for the delay - it took me a while to reliably reproduce the error. The common factor is the long delay before the crash. This delay, plus a couple lines about waiting for memory to free near the end of the log, leads me to believe the cause is a memory leak in VDPAU that causes...

Unfortunately, GPU decoding caused VLC to freeze with painful regularity (perhaps an unrelated issue), so I've switched back to CPU decoding for now. Do you have more info on this ? Unfortunately, I'm not sure how to debug this variety of crash. VLC remains open, but the video is paused/unresponsiv...

Thanks for the info unidan! Is there a release schedule for version 4 (I did some searching, but couldn't find it if it exists). Unfortunately, GPU decoding caused VLC to freeze with painful regularity (perhaps an unrelated issue), so I've switched back to CPU decoding for now. Thanks again for your...

Turns out, the underlying error was improper use of vlc.py. I had disabled X11 (--no-xlib) as recommended in the vlc.py error message. However, this in turn disables VDPAU. Thus, VLC was unable to take advantage of GPU decoding. For any other vlc.py users, calling XInitThreads() before you begin to ...

Hello! I'm hoping to reduce (or better yet, eliminate) the black screen that appears when switching in between files. To be clear, I'm not seeking true gapless playback, just playback with less of a visible gap in between files (it ruins the pepper's ghost illusion that we've created). Previous foru...

Update, for anyone experiencing a similar problem: After a great deal of debugging, I believe I have tracked my issue not to the set_mrl() function as I originally expected, but instead to the get_length() function. My use case demands that when a video reaches its end, the player is reset to an idl...

Sorry for the slow response! I can certainly try to listen for the parsing event, but I'm not sure how it is triggered (or how to listen to it). I assume you mean VLC is still in the process of parsing the file when I try to play it? Thanks for the suggestion! I will try to figure it out; if you kno...

Of course, no later than posting that reply did the error reappear (I would estimate the frequency to be around 1% of the time). I haven't been able to track down the culprit, but I will continue to investigate and report back.

If anyone has any thoughts, they are appreciated.

After fairly extensive testing, the error has not reappeared. I'm not sure why the short delay would prevent the error, but perhaps a pervious MediaPlayer function call was occupying the VLC instance and preventing it from properly executing MediaPlayer.set_media().

For anyone following this thread, the issue and errors arise from the MediaPlayer.set_media() function. Adding a short delay (0.05 seconds) before using this function seems to resolve the issue, but more testing is necessary to make sure that the problem is really gone.

Hi all, I am running videos in VLC through vlc.py. 95% of the time, the video plays normally with no errors. Every once in a while, a video fails to play and I receive three errors: [mov,mp4,m4a,3gp,3g2,mj2 @ 0x7fc428ca22c0] moov atom not found [00007fc428ce47f8] avformat demux error: Could not open...
