Memory Leak NdiSrc #107

Closed joru1407 closed 1 year ago

joru1407 commented 1 year ago

We're experiencing a huge Memory Leak Issue when using an NdiSrc on Windows. We've compiled the plugin with most recent NDI 5 SDK.

The following sample pipeline is enough to reproduce: $ gst-launch-1.0 ndisrc ndi-name="GC-DEV2 (OBS)" ! ndisrcdemux name=demux demux.video ! queue ! videoconvert ! autovideosink demux.audio ! queue ! audioconvert ! autoaudiosink

The memory usage of the process starts increasing within seconds. After a minute it takes more than 2GB and increases until system memory is completely full. The video output remains smooth until crash.

Can you also reproduce this with the newer version at https://gitlab.freedesktop.org/gstreamer/gst-plugins-rs/-/tree/main/net/ndi ?

Wow, thanks for your quick reply! :-)

I wasn't aware of this more recent repository. With the newer version from there, everything works perfectly without any memory leak.
