I try run example from videomixer2 : gst-launch-0.10 videotestsrc pattern=1 ! video/x-raw-rgb, framerate=\(fraction\)10/1, width=100, height=100 ! videomixer2 name=mix ! ffmpegcolorspace ! ximagesink videotestsrc ! video/x-raw-rgb, framerate=\(fraction\)5/1, width=320, height=240 ! mix. It working, i see picture with colored lines and rectangle with noise; at the same time process gst-launch eat memory. memory consumption grows untill oom killer will not kill the process; Reproducible: Always Steps to Reproduce: 1.execute some command that using module videomixer2. for example: gst-launch-0.10 videotestsrc pattern=1 ! video/x-raw-yuv,format=\(fourcc\)AYUV,framerate=\(fraction\)10/1,width=100,height=100 ! videobox border-alpha=0 top=-70 bottom=-70 right=-220 ! videomixer2 name=mix sink_0::alpha=0.7 sink_1::alpha=0.5 ! ffmpegcolorspace ! fakesink videotestsrc ! video/x-raw-yuv,format=\(fourcc\)AYUV,framerate=\(fraction\)5/1,width=320,height=240 ! mix. 2. wait while gstreamer eats ram. 3. Expected Results: Memory consumption must not grow.
Created attachment 290255 [details, diff] patch eliminates leakage This tiny patch proposed by developer gstreamer and fully eliminates leakage in the module videomixer2. I belive you should add this patch to portage tree right now do not wait release of gstreamer with amended.
That URL is incorrect and this package doesn't belong to gnome maintainers ;)
I believe new upstream releases will happen soon. Though pre-releases first, which would still probably mean a couple weeks for new stable releases. I don't think this memory leak is hit much, if at all, in general purpose gstreamer using desktop programs though. videomixer2 is more common in specific use cases, e.g putting together a security feed from multiple camera sources and such specific things.
This should be fixed in 0.10.31 that has just been unmasked. If you still have problems, feel free to reopen. Thanks for reporting.
