gst-plugins-bad nvdec element doesn't work

[bronstein87]

Hi! Thank you very much for your answer. What about version:

system: gstreamer version 1.16.2, win10 x64, compiler msvc 2015 x64

I did like you said, and changed pipeline like this:

filesrc location=D:/test_nvdec/jumanji.mp4 ! qtdemux ! h264parse ! nvdec ! gldownload ! videoconvert ! appsink sync = false

But there are still errors, something wrong with cuda... Do you have any idea how to resolve this

I think the system memory output for nvdec is only in GStreamer master.

On start up there is a normal cuda warning when draining that you see there.  I think the actual error is that an OpenGL context could not be created.  This warning: 'error: glGetString not defined or returned invalid value' generally means that the platform specific code created an OpenGL context but the attempt to retrieve necessary function pointers failed.

Can you try a couple of other pipelines like so to check if GStreamer OpenGL on windows requires using glimagesink as a video sink?  It does sound weird to me if true.

gst-launch-1.0.exe gltestsrc ! glimagesink
gst-launch-1.0.exe gltestsrc ! gldownload ! queue ! videoconvert ! d3dvideosink
gst-launch-1.0.exe gltestsrc ! gleffects_identity ! gldownload ! queue ! videoconvert ! d3dvideosink

For the pipelines in the above list that fail, can you grab a debug log with the following environment variables GST_DEBUG_FILE=/path/to/file GST_DEBUG=3,gl*:7 and create a new issue on gitlab at https://gitlab.freedesktop.org/gstreamer/gst-plugins-base/-/issues/new.

P.S. for your pipeline there is a glcolorconvert element that you could replace the videoconvert with if that would help.  The gldownload element would need to go after the glcolorconvert element of course.

Cheers
