Netflix vs Showmax - New data-saving codec tested

The Netflix mobile app for Android and iOS includes a unique feature which reduces data consumption when streaming using mobile data.

This is accomplished without a noticeable reduction in video quality by dynamically altering content bit rate depending on the motion in each segment of a video.
 
Up till now Showmax have been "using" MPEG2 judging by the quality and bandwidth I have experienced.

Still needs to be better optimized and supported. Way too early. H265 HEVC 10bit HE-AAC 9ch FTW!

See dav1d from VideoLAN
https://code.videolan.org/videolan/dav1d
dav1d 0.1.0 only had AVX2 optimizations - this covered 66% of modern Intel/AMD CPUs.

VideoLAN recently released 0.2.0 with SSE3 & NEON optimisations:

SSE3 - this covers 97.2% of older CPUs (All Intel & AMD 64 bit CPU's)
SSE4.1 covers 95.8% is is not yet implemented in dav1d.
NEON - All Arm64 CPU's

dav1d 0.2.0 can now decode 1080p at over 30-100fps without sweating on most CPU's released in the last 5 years.
Encoding still being worked on.

h265 and vp9 are outdated already. They should start working on av1 already :)

Should be, he's, but hardware decoder support would also be important for mobile devices.

App should check what the hardware supports and then make a decision.

And encoding AV1 takes an age, like 2-3 minutes per 10 seconds depending on what rate you want to get. Very rarely worth it.

Will get a lot better with hardware encoding support.
