Ubuntu 系統下 Gstreamer H.264 硬體解碼 hang 住
在 Ubuntu 系統下使用 Gstreamer 調用 plug-in : avdec_h264_rkmpp 進行 H.264 硬體解碼會 hang 住不動gst-launch-1.0 -vvv \
filesrc location="/home/firefly/1k30p.h264" \
! h264parse ! avdec_h264_rkmpp debug-mv=true ! videoconvert \
! fpsdisplaysink video-sink="kmssink plane-id=94" \
text-overlay=false sync=false
同樣以plug-in : avdec_h264 進行軟解 mp4 或 H264 raw data 可以正常運行顯示, cmd 如下 :
gst-launch-1.0 -vvv \
filesrc location="/home/firefly/1k30p.h264" \
! h264parse ! avdec_h264 ! videoconvert \
! fpsdisplaysink video-sink="kmssink plane-id=94" \
text-overlay=false sync=false
gst-launch-1.0 -vvv \
filesrc location="/home/firefly/1k30p.mp4" ! qtdemux \
! h264parse ! avdec_h264 ! videoconvert \
! fpsdisplaysink video-sink="kmssink plane-id=94" \
text-overlay=false sync=false
使用 avdec_h264_rkmpp 後 hang 住的 log 如下 :
firefly@firefly:~$ gst-launch-1.0 -vvv \
> filesrc location="/home/firefly/1k30p.h264" \
> ! h264parse ! avdec_h264_rkmpp debug-mv=true ! videoconvert \
> ! fpsdisplaysink video-sink="kmssink plane-id=94" \
> text-overlay=false sync=false

想請教各位大佬 是我在 gstreamer 組成上有遺漏什麼造成 cmd hang 住？
