The Raspberry Pi 4 maintains the familiar 40-pin GPIO, allowing for complex and interesting projects or even the addition of HATs and add-on boards to take your project further. Programming Perfection!įor those just wanting to get creative with code, this is what the Raspberry Pi was born to do. The improved performance also makes the Raspberry Pi 4 the perfect candidate for a media centre, NAS, server, gaming emulator and many other resource-intensive applications. With this new level of hardware, the Raspberry Pi 4 truly is a viable dual-display desktop computer. In terms of computing power, the Raspberry Pi 4 ships with a new 1.5GHz Quad-core CPU – the fastest we’ve ever seen on a Raspberry Pi offering around a 3x improvement in performance over the previous model!īacking up that processing power is up to a whopping 8GB of faster LPDDR4 RAM – the Raspberry Pi 4 comes in 1GB, 2GB, 4GB and 8GB options. The latest model of our favourite single-board computer includes great new headline features such as dual 4K (yes 4K!) displays, super-fast USB 3.0, Gigabit Ethernet and budget-accommodating RAM options. This is the final command that I've come up with and which I'm going to run now (will take a few hours, I guess):įfmpeg -i "Speed (1994) - 4k.mkv" -vcodec h264_omx -acodec aac -movflags +faststart -vf scale=1920:-2 -b:v 8000k -x264opts colorprim=bt2020:colormatrix=bt2020nc:transfer=smpte2084:chromaloc=2 "Speed (1994) - h264_HDRmapped.The Raspberry Pi 4 is the most powerful and feature-rich Raspberry Pi to be released, an incredible improvement on previous boards. Is this mapping universal tho? I really would like the command to be applicable to most of anything I throw at it, even things that don't have HDR. Regarding the HDR tone mapping, I'm trying to encode with "-x264opts colorprim=bt2020:colormatrix=bt2020nc:transfer=smpte2084:chromaloc=2" now. Allow video playback that requires conversion without re-encodingįor this to work because the audio has to be transcoded (to 2 channel, I presume), which the pi seems to be handling fine. Allow audio playback that requires transcoding I have to however allow for every single user:

I know that it's deprecated but since I'm running on 32 bit raspbian it should not be a problem, right? I really would prefer to not compile ffmpeg by hand.

So the workaround for now for me was to just use the h264_OMX encoder. My ffmpeg from the official repository seems to be even older than that!:įfmpeg version 4.1.9-0+deb10u1+rpt1 Copyright (c) 2000-2022 the FFmpeg developers He explains that it is due to the ffmpeg version being older than 4.3. This guy is also getting green artifacts in his video files:

#RASPBERRY PI 4K MEDIA CENTER 1080P#

How can I make the 1080p encode play? Why is the file size of the encode exploded to 27 GB (as opposed to the 7GB 4k version)? This feels unintuitive to meĪfter looking through the ffmpeg documentation and some stackoverflow, I think I've found the reason for the green video output. On the chromecast using the original emby app, it won't even start at all. However, when I try to play the resulting file in the browser, it is filled with green artifacts (see attachment). I also want to do hardware encoding on the raspberry pi (-vcodec h264_v4l2m2m made it convert roughly at 0.25, which is usable for me)įfmpeg -i Terminator\ 2\ Judgement\ Day\ \(1991\)\ -\ 4K.mkv -vcodec h264_v4l2m2m -acodec aac -movflags +faststart -vf scale=1920:1080 Terminator\ 2\ Judgement\ Day\ \(1991\)\ -\ 1080p.mp4 I chose what I believe to be a pretty universal format: h264 with AAC. (<- This is where I'm currently having issues with.)

For my lower power devices (like chromecast 2, old FireTV stick) I want to create a 1080p version with stereo audio and pretty ok quality. I want this file to be played for example on my LG smart TV.

If the video file is in 4k, I copy it to my movie collection and suffix the filename with "- 4K". Converted files still can't play without conversion (5.1 audio gets converted on the fly to stereo when playing on my chromecast) I can't "keep originals only if they are 4k, and always convert to 1080p"
