imxvpuenc_h264 doesn't output any data

Hello. I'm facing the trouble, I'm using imx6 Solo and I need to encode videostream by imxvpuenc_h264, but it doesn't output any data.

for example here is my pipeline:

# GST_DEBUG=WARNING gst-launch-1.0 -v multifilesrc location=/dev/fb0  \
  ! videoparse format=11 width=1024 height=768                    \
 ! imxipuvideotransform                                          \
  ! imxvpuenc_h264                                                \
 ! tee name=t                                                    \
 t. ! queue ! splitmuxsink muxer=avimux location=video%05d.avi max-size-bytes=1000000

here is part of output:

...

colorimetry=(string)bt709, chroma-site=(string)mpeg2
Setting pipeline to PLAYING ...
New clock: GstSystemClock
/GstPipeline:pipeline0/GstSplitMuxSink:splitmuxsink0/GstQueue:queue1: max-size-buffers = 6
/GstPipeline:pipeline0/GstSplitMuxSink:splitmuxsink0/GstQueue:queue1: max-size-buffers = 7
/GstPipeline:pipeline0/GstSplitMuxSink:splitmuxsink0/GstQueue:queue1: max-size-buffers = 8
/GstPipeline:pipeline0/GstSplitMuxSink:splitmuxsink0/GstQueue:queue1: max-size-buffers = 9
/GstPipeline:pipeline0/GstSplitMuxSink:splitmuxsink0/GstQueue:queue1: max-size-buffers = 10

...

/GstPipeline:pipeline0/GstSplitMuxSink:splitmuxsink0/GstQueue:queue1: max-size-buffers = 500

...

/GstPipeline:pipeline0/GstSplitMuxSink:splitmuxsink0/GstQueue:queue1: max-size-buffers = NNNNN

...

and result file size = 0 bytes:

# ls -la
-rw-r--r--  1 root root    0 Feb  7 15:54 video00000.avi

BUT

in that time if try to remove imxvpuenc_h264 from the pipeline, it works perfect

here is my gst-inspect:

Whats wrong?

Thanks!

Hi Eugene

imxvpuenc_h264 is part of gstreamer-imx plugins, issue may be posted

on Issues · Freescale/gstreamer-imx · GitHub 

Alternatively one can try imx-gst1.0-plugins described in Linux Guide included in

Linux 4.14.98_2.3.0 Documentation

Best regards
