# hwcodec for H.264 H.265/HEVC stopped compiling when it went from/to

# 1.3.0 hwcodec v0.7.0 vcpkg::ffmpeg (https://github.com/rustdesk-org/hwcodec#6abd1898)
# restored in 1.4.1
#
# To get H264 H265, rustdesk must be compiled with vcpkg::ffmpeg build modified by rustdesk.
# libva and appropriate libva hardware driver must be installed and rebooted. See optdepends.
# Client supports all soft codecs and compiled in hardware codecs.
# Client hardware decode support (VAEntrypointVLD) preferred but not required.
# Host offers all encode software codecs and only hardware codecs supported by hardware (VAEntrypointEncSlice).
# Linux host may disable H265 even if supported by hardware. https://github.com/rustdesk/rustdesk/discussions/4095
# Linux client does support H265, verified by connecting to a Windows host >= Skylake or Android.
# Use libva-utils::vainfo to list supported hardware codecs VAProfileH264Main or VAProfileHEVCMain
