Error while trying to encode jpeg image in appsrc deepstream

Accelerated Computing Intelligent Video Analytics DeepStream SDK
1

Hello,
I’m trying to create a deepstream pipeline in order to encode a set of images into a video using nvidia hardware acceleration using nvjpegdec and nvv4l2h265enc. The pipeline I’ve built is the following one: appsrc block=true name=“pipeline_name.mkv" caps="image/jpeg,width=1152,height=648" ! nvjpegdec ! nvv4l2h265enc bitrate=2000000 ! h265parse ! matroskamux ! filesink location=“”folder/pipeline_name.mkv"".
When running it I got the following error:

Any idea about what is causing this error and eventually how to solve it?

There is no update from you for a period, assuming this is not an issue anymore. Hence we are closing this topic. If need further support, please open a new one. Thanks

Can the following command line work fine ?

 gst-launch-1.0 uridecodebin uri=file://"your video path" ! nvvideoconvert ! video/x-raw"(memory:NVMM)",format=NV12 !  nvv4l2h265enc bitrate=2000000 ! h265parse ! matroskamux ! filesink location="folder/pipeline_name.mkv"

If ok, you can check the appsrc whether give the right input.
