FFMPEG AV1 ENCODE 1080P
FFMPEG AV1 ENCODE SOFTWARE

It is considered to be 'experimental' FFmpeg requires you to use either -strict experimental or strict -2 or it will refuse to run.įFmpeg can encode AV1 video in several modes. FFmpeg with libaom-av1 is one you likely have available on a modern GNU/Linux distribution. There are several competing encoders available for GNU/Linux. This is specially true if you are used to hardware accelerated video encoding. Expect to be shocked and amazed at how incredibly slow AV1 encoding is if you are used to encoding MPEG4-AVC video or even HEVC video. Warning: AV1 video encoding with libaom-av1 is really slow as in horribly slow on modern processors.

No AMD GPU can do AV1 hardware encoding.įFmpeg encoding a 1080p video as AV1 at a whopping 0.7 frames per second The 'Sienna Cichlid' and 'Navy Flounder' graphics card families (Navi 21 and 22) can do AV1 decode. You are out of luck if you have a AMD CPU paired with an AMD GPU or an AMD APU and you want to play 4K AV1 video on Linux - unless you have the very latest AMD graphics technology. There is no AV1 hardware video decoding in the AMD Polaris, Vega or the first Navi graphics cards families. Intel Tiger Lake processors with integrated graphics will be capable of hardware video decoding and Linux support is already in place in libva and FFmpeg. Is a question of single-threaded performance: A 12 or 24 core machine won't help when smooth playback requires one very fast core. The current single-core nature of AV1 playback on Linux means that you will need a machine with about 3x the single-core performance of a Ryzen 2600 to play AV1 video smoothly. The result of that is horrible stuttering. Trying to play the 4K file on a Ryzen 2600 results in one thread trying to use between 250 and 280% of one CPU core with a second thread eating about 50% of a second core and a few other threads using 5-10%. A close-up inspection of mpv 0.32.0-666-gb0f0be7678 linked against FFmpeg 4.2.4 on a Ryzen 2600 reveals one thread using between 50% and 80% of one CPU core with a second thread loading a second core at 10-20%. There is a fair chance that you will be able to play the 1280x720 Meridian-8MiB-AV1-Challenge.webm if you are using a Linux desktop or laptop computer. You can go right ahead and try to play both these files since you are much likely using a web browser with AV1 support. We have made two AV1-encoded video files available for your 'enjoyment': Playing 4K video using mpv version 0.32.0-666-gb0f0be7678 linked against FFmpeg 4.2.4 on a Ryzen 2600 with a RX 470 GPU results in very stuttering unwatchable playback due to one thread doing the vast majority of the work.

You will be able to play 1080p video on a moderately powerful modern machine powered by something like a Ryzen 1600X or a 2600 but you won't be able to smoothly play 4K video.Ī big part of the reason 4K video won't play on machines that are perfectly capable of CPU software decoding 4K HEVC video is likely the single-threaded nature of AV1 decoding in current versions of FFmpeg. Do not expect to be able to play AV1 video on an old or weak processor like the AMD Athlon 5350 APU, you won't even be able to play 1080p video. There is a fair chance that you, in practice, can't. You will, in theory, be able to play AV1 video both in web browsers and video players on any fairly recent GNU/Linux distribution.

Firefox has had AV1 video playback support over a year.

Chromium has had AV1 video playback support since version 70. AV1 video playback has been supported by FFmpeg and video players using mpv as well as other video players like VLC for quite some time.
