Mem copy error - NVMM - DeepStream

@le.lokaram.t

st-launch-1.0 v4l2src device=/dev/video0 ! jpegdec ! nvvideoconvert ! video/x-raw\(memory:NVMM\), width=1920, height=1080 ! fakesink sync=false

I use Jetpack 6.2 with Deepstream-7.1. Since I don’t have a USB camera, so I use videotestsrc as test source. The following pipeline works fine.

gst-launch-1.0 videotestsrc  ! video/x-raw,format=I420, width=1280, height=720 ! nvvideoconvert compute-hw=1 copy-hw=1 ! video/x-raw"(memory:NVMM)", width=1920, height=1080 ! fakesink sync=false

@Failed in mem copy

a lot for pointing this issue out, and we will be fixing it in the uncoming release. Currently, you can try the below pipeline first as a WAR. GST_DEBUG=3 gst-launch-1.0 nvurisrcbin uri=file:///opt/nvidia/deepstream/deepstream-7.1/samples/streams/sample_1080p_h264.mp4 ! m.sink_0 nvstreammux name=m batch-size=1 width=1200 height=1920 ! nvvideoconvert compute-hw=1 nvbuf-memory-type=3 ! x264enc ! h264parse ! mp4mux ! fakesink

I tested it for hours, this workaround is effective
