how to test exp_refactor_all branch #37

Open hbiyik opened 8 months ago

hbiyik commented 8 months ago

  1. to use p010/yuv420p10 10bit formats you need this fix in the vendor kernel and this fix in rgamulti

  2. compile with --enable-shared additional to the description in wiki

  3. manipulate the LD_LIBRARY_PATH to point the .so files from the build folder ie:

    export PATH="/home/alarm/extusb/ffmpeg:$PATH"
export LD_LIBRARY_PATH="/home/alarm/extusb/ffmpeg/libavcodec:$LD_LIBRARY_PATH"
export LD_LIBRARY_PATH="/home/alarm/extusb/ffmpeg/libavdevice:$LD_LIBRARY_PATH"
export LD_LIBRARY_PATH="/home/alarm/extusb/ffmpeg/libavfilter:$LD_LIBRARY_PATH"
export LD_LIBRARY_PATH="/home/alarm/extusb/ffmpeg/libavformat:$LD_LIBRARY_PATH"
export LD_LIBRARY_PATH="/home/alarm/extusb/ffmpeg/libavutil:$LD_LIBRARY_PATH"
export LD_LIBRARY_PATH="/home/alarm/extusb/ffmpeg/libpostproc:$LD_LIBRARY_PATH"
export LD_LIBRARY_PATH="/home/alarm/extusb/ffmpeg/libswresample:$LD_LIBRARY_PATH"
export LD_LIBRARY_PATH="/home/alarm/extusb/ffmpeg/libswscale:$LD_LIBRARY_PATH"

    use a sscript like above where it points to your build/install folder, save it to setpath.sh, then execute source setpath.sh. Now your which is spawned from this environment (cli), will use the new ffmpeg

  4. to test with kodi, build kodi with external ffmpeg usage. You can refer to this PKGBUILD on how to do this.

run kodi with:

kodi.bin --windowing=gbm --audio-backend=alsa

make sure you select

settings->player->videos->render method
Allow using DRM PRIME Decoder=enable
Allow Hardware Acceleation with DRM PRIME=enable
Prime Render Method=EGL

IMPORTANT: Make sure your audio is working, otherwise playback will stop after several seconds due to unsynchronized picture and sound.

  1. To test with mpv run with below commandline args. mpv --hwdec=rkmpp pathtofile IMPORTANT: to decode drm_prime NV16 frames you either need latest git version of mpv or below patch IMPORTANT: to decode drm_prime P010 below patch IMPORTANT: if you receive an error like `Mapped surface with format 'nv12' has unexpected number of planes. (0 layers and 0 planes, but expected 2 planes),``build mpv from git, this is an issue with mpv and fixed in the latest.

Subject: [PATCH 1/2] hwdec_drmprime: add nv16 support

NV16 is the half subsampled version of NV12 format. Decoders which
support High 4:2:2 of h264 provide the frame in NV16 format to establish
richer colorspace. Similar profiles are also available in HEVC and other
popular codecs. This commit allows NV16 frames to be displayed over
drmprime layers.
