Are the V2 codecs stale?

Post by mishmash » Fri Jul 16, 2021 22:45

Hi there,
I went to watch a video last night and all I got was the audio of the file and a still picture of the free-to-air broadcast.
I suspect the encoding was beyond the V2's capability.
Is this where it ends for the unit?

Cheers!

If it helps, here's some of the file format info:

I think I recall a post from peteru stating the Wizes can't do "high" format profile.
Re-encode it and see how you go.

On second thoughts, I think that format profile capability applied to the V2's predecessors.
Perhaps the bitrate is too high for the decoder.

I think the same applies to the V2. High profile AVC is not well supported.

You sometimes find Anime encoded that way because it tends to encode the colour shading better.

Thanks for the responses.
I sort of figured the little guy was struggling with the file.
I'll avoid that encoding in future for stuff I want to watch via the Wiz.

These days, with modern playback devices you are better off with HEVC for the better quality/efficiency anyway.

I'm finding similar occasional problems with shows from the UK. Handbrake is our friend...

Mr Quade....does the V2 support this wonderful standard?
Pardon my ignorance....

Yep. HEVC or h.265 is supported by the V2 (and U4) hardware.
It's the same encoding used on 4K UHD disks.

However low power devices and other technology more than about 5 years old will likely have problems with it.

For just about every consumer level device, the upper limit for AVC is High@4.1. Going to 4.2 is unlikely to work reliably and is not advisable. Level 4.2 requires the decoder to be able to handle double the macroblock rate of Level 4.1. That means building silicon that can do twice as much work! Level 4.2 also gets you higher frame rates, however, the higher frame rates are unlikely to be needed in typical streaming or broadcast scenarios, which these SoCs are made for.

By far the most compatible option is to select High@4.1 H.264 / AVC encoding with AC3 or E-AC3 sound. That ought to work the best on all Beyonwiz models and many other devices. Avoid AAC sound whenever you can. If you end up with AAC that has more than 2 channels, you are better off if you transcode the audio to E-AC3.
