# hwcodec for H.264 H.265/HEVC stopped compiling when it went from/to
# 1.2.7 hwcodec v0.6.0 builtin       (https://github.com/21pages/hwcodec#89879f2f)
# 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/HEVC rustdesk must be compiled with vcpkg::ffmpeg build modified by rustdesk.
#
# Client and host soft codecs VP8 VP9 AV1 supported on all platforms.
# Client and host hardware codecs H264 H265 require
#   Install hardware codec library package matched to the CPU or video card. restart rustdesk.
#   See optdepends for which package to use.
# Host hardware codecs require
#   CPU or video card support
# Use vainfo from libva-utils to list supported hardware codecs.
#      VAProfileH264Main               : VAEntrypointVLD
#      VAProfileH264Main               : VAEntrypointEncSlice
#      VAProfileHEVCMain               : VAEntrypointVLD
#      VAProfileHEVCMain               : VAEntrypointEncSlice
# Client requires hardware codec library. Codec decode support (VAEntrypointVLD) is not required.
# Host requires hardware codec library and hardware encode support (VAEntrypointEncSlice).
# Linux host may disable H265 even if supported by hardware.
# https://github.com/rustdesk/rustdesk/discussions/4095
# Linux client without H265 decode does support H265,
# verified by connecting to a Windows host >= Skylake or Android.

# H264 and H265 have quality issues affected by both client and host.
# One client will see heavy pixelation and green rectangles. Another
# client will be perfect. Switch between different codecs to improve quality.
# I find the best quality in this order: AV1, VP9, VP8, H264, H265
