Appsrc+nvvidconv+appsink results in error

[HooverLv]

The environment is tx2 4G.
I am trying to reduce CPU usage in color space conversion from UYVY to RGBA.
So I setup a pipeline in my code using appsrc+nvvidconv+appsink, but as soon as I push a first UYVY frame into the pipeline, it reported internal data error and ceased to playing. could tell me what could be the reason? with GST_DEBUG, I can see the first error reported from nvvidconv. as in attached log, i.e.
0:00:45.825118624 11918 0x7f742f8230 DEBUG basetransform gstbasetransform.c:2323:gst_base_transform_chain: we got return error
please also check in attached sample codes.

Hi,
Please refer to the sample:

appsrc link to nvvidconv error with reason not-negotiated(-4)

Below sample works fine. FYR. $ gst-launch-1.0 videotestsrc num-buffers=1 ! video/x-raw,format=RGBA,width=2048,height=1080 ! filesink location=a.yuv $ ./test #include <cstdlib> #include <gst/gst.h> #include <gst/gstinfo.h> #include <gst/app/gstappsrc.h> #include <glib-unix.h> #include <dlfcn.h> #include <cstring> #include <iostream> #include <sstream> #include <thread> using namespace std; #define USE(x) ((void)(x)) static GstPipeline *gst_pipeline = nullptr; static string launch_string; s…

The source is in RGBA format. You may change to UYVY and try.

thanks. following you sample and that works.
