There has to be a way to wrap the driver allocated buffers in a GstMemory object without the possibility of them being orphaned. GstMemory has no knowledge of externally supplied buffers that I can see. It has a function to wrap them though. Should there not be a flag resident in the object that denotes it as wrapped or not and if wrapped not to attempt memory replacement?</div>

Hello,<br>
<br>
I am trying to get the uvch264src to work in gstreamer 1.1.1.1 (git head compiled yesterday) with the following pipeline:<br>
<br>
gst-launch-1.0 uvch264src device=/dev/video1 name=src auto-start=true src.vfsrc ! queue ! video/x-raw,width=320,height=<u></u>240,format="YUY2",framerate=<u></u>15/1 ! xvimagesink src.vidsrc ! queue ! video/x-h264,width=1920,<u></u>height=1080,framerate=30/1,<u></u>profile=constrained-baseline ! h264parse ! avdec_h264 ! xvimagesink<br>
<br>
It runs as expected (showing both the 1920x1080 and 320x240 windows). But it constantly prints warnings (see below). Then stops it . You can find the GST_DEBUG output below the warnings below.<br>
<br>
It works stable with gstreamer 0.10 (an older compilation) and<br>
<br>
gst-launch uvch264_src device=/dev/video1 name=src auto-start=true src.vfsrc ! queue ! video/x-raw-yuv,width=320,<u></u>height=240,framerate=15/1 ! xvimagesink src.vidsrc ! queue ! video/x-h264,width=1920,<u></u>height=1080,framerate=30/1,<u></u>profile=constrained-baseline ! h264parse ! ffdec_h264 ! xvimagesink<br>
<br>
I am using a C920.<br>
<br>
I found a (probably) related problem here:<br>

<br>
<br>
Do I do something wrong in gstreamer 1 or is this a bug?<br>
