the 720p file ran like a champ but the audio codec was not supported =P

I tried the 1080p sample again with HW+ enabled, frame rate was like a slideshow but at least there were no artifacts or blotches.

I am going to have to try both on my v6000 HDT!

actually that's quite good... 720p hi10p playback is ok... 1080p hi10p not good. There are forums talking about how to enable dts encoding in MX Player. it is simple to do (download a file and point to it from mx player).

right now the only thing that really plays 1080p hi10p is the Tegra3 though (though playback is not perfect...)

heh heh... not exactly android, but acer is releasing their Iconia W700 later this month. a 11inch Windows8 tablet with an i5 that should be able to decode just about anything you throw at it... all for the um... high high price of $900 usd.

Being a Software developer I am probably going to pick one up for um dev purposes yeah... not so I can have a tablet that can play anything.... um... anyone believe me? thought not... yeah it's a toy.

Too big and too expensive for what is essentially a media player. Maybe the next gen SOCs will have good support? What is the roadmap for Tegra4 and the Chinese manufacturers (AMlogic, Rockchip...)?

I think Rockchip announced that they are working on their next gen of chips and they will be quad core.

Not Android, but here is something that interesting - the iPhone 5 with the A6 chip looks like it can handle 720p hi10p videos quite well - iPhone 5: Flawless 10-bit MKV Playback - YouTube

That means the new iPad with the A6X should also give similar playback performance.

Um the The Nexus 7 with it's Tegra 3 processor is handling 1080p hi10p using MX Players HW+ mode with a few artifacts as linked previously.


As a note, just because you see little artifacts on a video does not mean the Tegra 3 can playback hi10p videos perfectly (some vids will show little artifacts while other will show a lot). Software decoding is the only way to go. Unfortunately, the Tegra 3 only gives usable playback on hi10p 720p video when it's OCed to at least 1.5ghz on all cores (tested on my Transformer Prime when I was able to OC up to 1.6ghz). While usable, you still see frame drops during high motion scenes or during panning. 1080p hi10p vids are out of the question.

Even the Snapdragon S4 1.5Ghz dual-core on a lot of new phones also has problems with 720p hi10p videos too - some videos will play okay, some will play fine, others will not play well using software decoding on MX Player. I personally never test hi10p vids using the hardware decoder because no SoC, to my knowledge, can hardware decode 10-bit videos.

Is it really necessary to use such high resolution videos on a tablet, apart from bragging rights, the screen isn't like your TV and the visible resolution is greatly limited.

True, but the issue is not having to re-encode existing stuff you have just to play it on your tablet. And there's really no reason why tablets shouldn't be able to handle this, just needs a bit more hardware decoding support and it will work flawlessly with low power consumption

But its quite evident that tablets and android, and possibly the hardware are not wanting you to play them directly on the tablet, but wanting you to stream movies and shows direct, i.e like Amazon and Google plus all the other streaming services, with this in mind it may be redundant to add more and more hardware comparability when the main picture is to get things off the tab and get us all on the cloud and stream our lives away - of course there is a pocket of people that want things a certain way but unfortunately when something gets to a point like this the needs/wants of the few are pushed aside and you dont fit the bigger picture

They may want everything streamed, but wireless network connections are not up to it in the majority of countries. Right now it's still a download market. And Amazon and Google do not determine what goes into a CPU and what not. A lot of people (not some tiny minority) do not like the walled garden setup Apple uses, prefer for this reason Android and for the same reason avoid Amazon. If Google locks Android and creates a similar closed system, they'll lose a lot of customers. So I doubt it is going to be as simple as you say. There will be CPUs that have HW support for 10bit sooner or later, or they will simply become so powerful they can handle it in software decoding. It's only a matter of time.

A few years back I played my fansubs on a PPC. Everything was Xvid and it played fine in normal resolution without recoding on the later generations. Once h264 made the breakthrough, the PPCs couldn't keep up. Then tablets became popular, and they had no problems with h264. When the next codec gen shows up, (soon I suspect, the spec is final IIRC) I'm sure hardware support will follow and 10bit backwards compatibility will be included as well. Cloud is a fad that will take a looong time to mature. Too many legal issues (we don't use it because the data can be offshored, which is not allowed for us by law) and too many stability issues. Not to mention internet speed is still pretty slow here. VDSL full coverage is planned here for 2030 or later. A lot of countries will take even longer. Don't be taken in by the hype, cloud is hyped because the companies backing them are in trouble with their old products (Windows 8 anyone?), not because it is so much better.
