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



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


here is my gst-inspect:

Whats wrong?
