Finally I can use libgstmsdk.so compiled from gstreamer-1.17 (not released yet) code to decode online videos with iGPU. Unfortunately, Bilibili (and several other video websites) work but Youtube not. I think the new driver stack is still too premature. Arch don't use it for Gstreamer, and just began to test it for ffmpeg: https://www.archlinux.org/packages/testing/x86_64/ffmpeg/ Let's wait. -- Xi Ruoyao <xry...@mengyan1223.wang> School of Aerospace Science and Technology, Xidian University -- http://lists.linuxfromscratch.org/listinfo/blfs-dev FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
