Support for HEVC/H.265

[ademarfj]

Hi,
Do you intend to add support to HEVC?

[Paul]

Yes, Mezzmo supports HEVC / h.265. Several of the Mezzmo device profiles already have it included for those devices that support playing this video codec.

One of the challenges with HEVC / h.265 is that it is barely supported in GPU hardware right now and without hardware support it is a tremendous CPU hog on general purpose CPUs. Also, the file size savings is around 40%. It is going to be interesting to see the adoption of this newer standard. At lower bit rats general purpose CPUs may be fine but at higher quality bitrates, hardware GPU or special purpose hardware will be a must.

Thanks for your answer!

Hello,

I relaunch this old topic as one year has passed and now hardwares are available with capacity to read h265. FFMPEG is able to manage it. So I repost ademarfj's question : is there any roadmap to implement h265/hevc support?

Thank You

Hi Rirou,

Mezzmo v5.x supports h.265 / HEVC already :).

Many Mezzmo device profiles already have this h.265 / HEVC support included for those devices that support playing this video codec.

If you have a device that supports h.265 / HEVC and want a device profile for it, then let us know and we'll help out.

Thank you Paul

That means that you had answered this wish before I make it (and also that I should have read more carefully Mezzmo 5.x new features list before asking ;) )

Then I will rework the profile I have sent to your team few months ago for Sagem Livebox 4 (as this device support HEVC and 4K).

If you allow me to give a friendly advice : you should update the list of supported format below to highlight this "more than nice to have" feature http://www.conceiva.com/products/mezzmo/formatsupport.asp#VideoRead

Best Regards

Thanks for letting us know, Rirou. We will update the supported formats web page. If you have problems with the device profile, let us know and we'll help out.

Thanks for your answer!

Just to add, I've been using H.265 for a good 12 months with Mezzmo now (my TV supports playback natively), and it works very well.

Encoding files from source, does take a little longer, and I'm still waiting for mobile devices to catch up in terms of support (my iPhone 6 is a little choppy during playback) - but that will only be a temporary issue before HEVC is the norm.

There is clearly a lot of effort being put behind adopting it now as we look to 4K content delivery, and it's well worth adopting if you have a large media database.

Thank @Paul so much! I'm using Mezzmo v5.1.1 :)
