Since gstreamer is packaged by Ubuntu, you may want to report the bug on Launchpad.

Got context from element 'vaapipostproc0': gst.gl.GLDisplay=context, gst.gl.GLDisplay=(GstGLDisplay)"\(GstGLDisplayX11\)\ gldisplayx11-0";
Got context from element 'vaapipostproc0': gst.vaapi.Display=context, gst.vaapi.Display=(GstVaapiDisplay)"\(GstVaapiDisplayDRM\)\ vaapidisplaydrm1";

The problem is probably related to vaapi decoding. Though it's somewhat strange if it appears to be using vaapi on the Nvidia version of Pop!_OS, since nvidia's proprietary drives doesn't use that API.

Ran Ubuntu 20.10 from 'live USB', no issues with gstreamer using the default X-org Nvidia driver (nouveau?). I currently cannot reproduce the issue on an Ubuntu 20.10 live environment.

I've tested it on a physical install of Ubuntu 20.10 and tested with:

I cannot reproduce the same error on Ubuntu 20.10.

ids1024 commented 3 years ago

Interesting.

Do you see segfaults consistently with certain video formats, or are there particular videos you have this issue with? I'm not sure how to try reproducing it.

mkorenbl commented 3 years ago

I see them with multiple formats: MK20191114-DSCF0028.MOV: ISO Media, Apple QuickTime movie, Apple QuickTime (.MOV/QT) video-2012-07-20-18-31-00.mp4: ISO Media, MP4 Base Media v1 [IS0 14496-12:2003]

Video files are from:

I don't know if it's related but I am also seeing GStreamer segfaults on some videos and inability to play them entirely. I've been reproducing it using gst-play-1.0 and GIFs from Twitter. For example:

> gst-play-1.0 https://video.twimg.com/tweet_video/FNj3y7jXMAAcl8k.mp4
Press 'k' to see a list of keyboard shortcuts.
Now playing https://video.twimg.com/tweet_video/FNj3y7jXMAAcl8k.mp4
Prerolling...
Redistribute latency...
fish: “gst-play-1.0 https://video.twim…” terminated by signal SIGSEGV (Address boundary error)

Using the linked script also causes segfaults on the given videos:

> python3 tmp/software/gstreamer_basic_test.py FNj3y7jXMAAcl8k.mp4
gstreamer initialized
fish: “python3 tmp/software/gstreamer_…” terminated by signal SIGSEGV (Address boundary error)

I tried to extract the video from https://twitter.com/CurbJumpingNYC/status/1502278203406229504 too.

> gst-play-1.0 'https://video.twimg.com/ext_tw_video/1502277840536055817/pu/pl/dBYyXiSe-qZVfEqm.m3u8?tag=12&container=fmp4'
Press 'k' to see a list of keyboard shortcuts.
Now playing https://video.twimg.com/ext_tw_video/1502277840536055817/pu/pl/dBYyXiSe-qZVfEqm.m3u8?tag=12&container=fmp4
fish: “gst-play-1.0 'https://video.twi…” terminated by signal SIGSEGV (Address boundary error)

I wasn't as clear on how to download the actual data (trying to retrieve this file produces an M3U and the Python script doesn't seem to work on it).

This is a System76 Lemur Pro that I had bought a couple years ago and came pre-installed with I think 19.10, but that I had never used until dusting it off last weekend and upgrading it.

You may want to report the issue to the gstreamer project with the sources and flatpak info. In the meantime, perhaps try out mpv / libmpv instead.

glasserc commented 2 years ago

I have opened https://gitlab.freedesktop.org/gstreamer/gstreamer/-/issues/1083 with most of the same information as above.
