I am having trouble connecting the nvv4l2decoder to nvstreammux using DeepStream. Currently I am just trying to read a video from a file, convert it to a format nvinfer could use, and then save it in a new video format. My gst pipeline looks something like:
source.mp4 → qtdemux → h264parse → nvv4l2decoder → nvstreammux → nvstreamdemux → nvv4l2h265enc → filesink.
I tried using both a bash script and compiling it to c (I tried bash because I was unsure if I was creating pads correctly with in C). Both give errors.
Bash Error: “WARNING: erroneous pipeline: could not link nvv4l2decoder0 to nvstreammux0”
C Error: " Running…
Pipeline ready
Dynamic pad created, linking demuxer/decoder
Dynamic pad created, linking demuxer/decoder
ERROR from element qtdemux: Internal data stream error.Error: Internal data stream error."
The Previous GST pipeline, worked:
source.mp4 → qtdemux → h264parse → nvv4l2decoder → nvv4l2h265enc → filesink.
