This is a waylandsink issue: I'm pretty sure that the issue is that the wl_display is destroyed when it should not be, hence why it fails the second time. Which version of GStreamer are you using? If you're able to try a quite current version, could you please give that a go? If not, or if it is a current version, could you please file a bug on gnome.org against GStreamer - if you could please CC George Kiagiadakis and myself too, that'd be great. Thanks, and sorry for the confusion. We use Gstreamer 1.4.5 version. Because of glib dependency, I'm not able to modify the working version to latest. All I'm able to do is to merge some specific code lines or apply a patch. I'll fallow your advice. Thank you ! |

Created attachment 118870 [details] Working time Hi, I need some help on debugging the following crash. This is happening during playing a video(reusing the pipeline). Interesting that, the crash in happening when opening the second video(first is played without issues). Attached to this bug are the traces at working time and bellow are the traces when crash is happened.
