Hello, does anybody have a working gstreamer pipeline for the imx6 with HW video decoding?
Following https://trac.gateworks.com/wiki/ventana/vpu I setup the HW and gstreamer reports rd@mo:~$ gst-inspect-1.0 | grep -P "v4l2.*dec" video4linux2: v4l2h264dec: V4L2 H264 Decoder video4linux2: v4l2jpegdec: V4L2 JPEG Decoder video4linux2: v4l2mpeg2dec: V4L2 MPEG2 Decoder video4linux2: v4l2mpeg4dec: V4L2 MPEG4 Decoder rd@mo:~$ I also allocated extra cma memory rd@mo:~$ cat /proc/cmdline console=ttymxc0,115200 quiet cma=256M rd@mo:~$ But I did not manage to get a working h264 playback: # gst-launch-1.0 filesrc location=/mnt/net/fs/mnt/disk/scratch/xbian/storage/ videos/Erdmännchen/002_Zum_in_die_Luft_gehen.mp4 ! rtph264depay ! v4l2h264dec ! kmssink name=imx-drm sync=0 Which outputs Setting pipeline to PAUSED ... Pipeline is PREROLLING ... ERROR: from element /GstPipeline:pipeline0/GstFileSrc:filesrc0: Internal data stream error. Additional debug info: ../libs/gst/base/gstbasesrc.c(3132): gst_base_src_loop (): / GstPipeline:pipeline0/GstFileSrc:filesrc0: streaming stopped, reason error (-5) ERROR: pipeline doesn't want to preroll. Setting pipeline to NULL ... Freeing pipeline ... When I use gstreamer's playbin, I get no errors, but the video is not displayed properly and on the output are messages that the HW is too slow (I assume in this case the HW decoder is not used). Any idea or hint is welcome. Many thanks Rainer -- Rainer Dorsch http://bokomoko.de/
