Raspberry
Pi 4B support HDMI 2.0 with dual micro-HDMI ports
should be able to support up to two 4K
displays at 30Hz or a single 4K display at 60Hz.
Raspberry Pi 4's new VideoCore 6 GPU can
playback 4K@60FPS H.265-encoded video, and this is
being targeted for support in the Kodi media centre.
Max resolution 4K 60Hz
+1080p or 2x 4K 30Hz
omxplayer doesn't support software
decode at all, so it will only play back H264 and
MJPEG
on Pi4.
Latest versions of VLC should be able to
use the
hardware
HEVC
acceleration.
H.264
The H.264 codec is a popular standard for high
definition digital video. It’s a versatile codec that
works with very high and very low bitrates. For example,
it can send low resolution and highly compressed videos
across the web and then can easily encode high
definition movies at high bitrates to play on a HD
television. The H.264 codec is often used with digital
video cameras and camcorders and it uses the AVCHD
container.
H.265
H.265, or High Efficiency Video Coding(HEVC),
is a new video coding standard that specifies how to
decode video, which is the successor to Advanced Video
Coding (AVC), also known as H.264.
VP9
VP9 is YouTube’s open source alternative to HEVC.
MPG – MPEG Video File
The video file format integrates MPEG-1 and MPEG-2
video and audio compression. MPEG-1 is almost
exclusively used for VCDs (Video Compact Disks ). MPEG-2
(also known as H.262) is used for DVDs and broadcast
HDTV.
