The videosink seems to use X11 and something goes wrong with the window and the window manager complains about that... or something like that. matchbox is the yocto window manager, but this errors should come somewhere out of libX11. https://www.yoctoproject.org/tools-resources/projects/matchbox > > > > [...] > > > > NvxVideoDecoderAcquireResources : NvxNvMMTransformOpen failed > > > > ERROR: from element > > /GstPlayBin2:playbin20/GstURIDecodeBin:uridecodebin0/GstDecodeBin2:decodebin20/Gs > > tOmxMpeg4Dec:omxmpeg4dec0: Could not decode stream. > > > > Additional debug info: > > > > gstomx_util.c(1137): EventHandler (): > > /GstPlayBin2:playbin20/GstURIDecodeBin:uridecodebin0/GstDecodeBin2:decodebin20/Gs > > tOmxMpeg4Dec:omxmpeg4dec0: > > > > There were insufficient resources to perform the requested operation > > > > ERROR: pipeline doesn't want to preroll. > > > > Setting pipeline to NULL ... > > > > NvxVideoDecoderAcquireResources : NvxNvMMTransformOpen failed [...] > > > > > > ... this here maybe the problem is that all memory is used after a few > > > frames.

You can get even more verbose debug logs via GST_DEBUG=5, maybe this helps as I don't know which category the interesting information could be in... if any at all.

However better support from the GStreamer community usually.
