XnView Software

1.7.2 succeeds at thumbnailing a folder of 5,500 videos, which 1.9.5 and many of the 1.8.x versions fail to do between 1-10%.

Using the following commandline, I was able to launch XnViewMP with strace and view all of the syscalls performed by the process. (the /usr/bin/xnview shell script usually prevents this.)


LD_LIBRARY_PATH=/opt/XnView/lib:/opt/XnView/Plugins QT_PLUGIN_PATH=/opt/XnView/lib QT_XCB_GL_INTEGRATION=xcb ...

please try with QT_XCB_GL_INTEGRATION=xcb_egl


Using debug=2 and the above environment variable on XnViewMP 1.9.5, I don't get much output on Ubuntu 22.04 and 24.04 LTS (two machines). It seems like the video thumbnailer thread deadlocks.

Here are the last few lines.
