Title: piCore64 ffmpeg/gstreamer hw acceleration
Post by: Juanito on July 06, 2021, 04:57:00 AM

With the recent changes to the graphics/v4l-dev-KERNEL extensions, bcm2835-codec loads automatically enabling hardware accelerated codecs for ffmpeg and gstreamer.

Code: [Select]

$ ffplay -i video.mp4 -vcodec h264_v4l2m2m

Code: [Select]

gst-launch-1.0 -v filesrc location=video.mp4 ! qtdemux ! h264parse ! v4l2h264dec capture-io-mode=4 ! autovideosink

mpv added to play video via ffmpeg - works in both x11 and wayland.

Note that on RPi4 only h264 hw acceleration works, hevc seems to be a work in progress.

With the update to sdl2, ffplay now works in x11 and wayland.

Totem works in both, but only if dbus and/or pulseaudio is used

Using the forked ffmpeg from: https://github.com/jc-kynesim/rpi-ffmpeg

hevc hardware acceleration works:

Code: [Select]

$ ffmpeg -no_cvt_hw -hwaccel drm -vcodec hevc -i ~/Downloads/jellyfish-25-mbps-hd-hevc.mkv -f vout_egl /dev/null
