[Mesa-dev] [PATCH 4/6] st/omx/tizonia: Add H.264 decoder

Gurkirpal Singh gurkirpal204 at gmail.com
Sat Jan 20 02:21:04 UTC 2018


v2: Refactor out screen functions to st/omx

Example Gstreamer pipeline :
gst-launch-1.0 filesrc location=movie.mp4 ! qtdemux ! h264parse ! omxh264dec ! videoconvert ! ximagesink
