Video Playback: Blu-ray Quality in a Tablet

One of the biggest issues with Tegra 2 based tablets and smartphones is a limitation that prevented hardware accelerated decode of any high profile H.264 video content. You could still decode the video but the additional stages of the decode process were left to run on the CPU, which in turn resulted in substantially lower battery life. NVIDIA has completely addressed the problem with the Tegra 3's video decoder, which is now capable of decoding 1080p H.264 high profile streams at up to 40Mbps.

The Honeycomb video player (Gallery app) will play .mkv files by default but if you want to throw on a .m2ts file you'll need to grab a third party player. DICE Player for Android supports Tegra 3's hardware acceleration, making it a good option if you want broader file compatibility.

Android File Transfer won't push over a file greater than 4GB so the first thing I tried was ripping a portion of A Quantum of Solace (BD) and sending over a 40Mbps High Profile 1080p MKV of it. The resulting 10 minute segment was 2.8GB in size and played beautifully on the Prime. There were no dropped frames and no hiccups, it just worked.

External NTFS volumes are supported and the sdcard file system supports files greater than 4GB in size, so I copied a 15GB 1080p Blu-ray rip of A Quantum of Solace from a USB stick to the Prime. I had to use DICE Player to get audio but otherwise the clip just worked. The biggest pain was copying the huge file across, but it'd be quicker and less painful than a re-encode on most systems.

To really test my luck I threw a few of our media streaming test files at the Prime. Our 720p60 test file worked perfectly, while our 1080p60 test case was mostly smooth with the exception of occasional slowdowns. I tried playing back a 1080p30 VC1 file however I couldn't get it to play back with hardware acceleration. Some of the more exotic combinations of features and file types wouldn't work, although I suppose that could be the fault of the playback software.

As far as I can tell, Tegra 3 and the Eee Pad Transformer Prime in particular are capable of playing back 1080p24 Blu-ray class video. Total NAND capacity is the only thing limiting us from just dumping a raw Blu-ray rip onto a tablet and playing that directly. Pretty much any HD rip you make yourself or find online will likely work. You may still need to invest in a good third party player to ensure things like subtitles are properly supported however.

I'm pleased with the state of video on the Prime. It's not HTPC level, but we can finally play really good quality video on an Android tablet. I suspect it'll be one more generation before we get tablets (and associated software) that will just play anything you throw at them.

    I'm glad you brought up the fact that the Prime has a higher resolution than the iPad2, I think a lot of people overlook that when then see performance numbers. This seems to be the tablet I wanted when I bought my 1st gen iPad, if I like it, I'm done with Appletunes. Thanks for the good review.

    They were reviewed at the same resolution(s)...

    CNET reviewers also got a unit with defective WIFI. So don't worry - you are not alone.

    Nice review. As an original Ipad owner I am always interested in new tablets but so far nothing since the original Ipad would get me to replace my current tablet. I did get my wife an Ipad 2 and while it is speedier the function of my original product still holds up.

    I really don't get the back camera on these things-a tablet is too big to really use as one's camera of choice and if you have a tablet surely a phone would be preferable? The front facing cam I understand and that would let people do the facetime/skype thing which I see as potentially useful.

    I take my Ipad to work with me. When I have spare time, I'll use it to check my email-much easier to read on the Ipad than my phone and the Ipad facebook app is pretty good. If things get really slow I can open a book and read. Rarely I'll watch something on Netflix but currently I don't have Netflix going because the kids grab the Ipad at home and watch cartoons instead of doing homework.

    As to doing work I just don't see it. A few months ago I got a Toshiba 14 inch laptop from Best Buy for 500 bucks. My thought was if I got good use out of it I'd get a Macbook Air and toss the laptop to the kids but technical limitations at work prevent me from doing what I'd really like with the notebook. The Toshiba laptop has an Intel processor with the Intel graphics, I doubt it could game and never tried, but it tosses up web pages nicely and has a nice keyboard. I can do work on it and don't mind typing on it. To do work I need Windows compatibility and I can't see where the Asus tablet would help me there.

    So, I don't really get this docking station except for a way for Asus to make a few extra bucks for people who don't know what they want to use a tablet for. To me a tablet is something lightwight you use for data consumption, and for "work" you need something that runs Windows software and is reasonably designed for data entry.

    The Windows 8 tablets might be the place where things are headed but a Win8 tablet with a docking station keyboard is a notebook.

    I guess we'll see where all is headed.

    The rear facing camera can be used for scanning in documents using google documents or other scanning applications. The better the quality of the camera, the better the quality of the resulting product. The best camera you have is the one you have with you all the time. If you are using your tablet as your work machine, having a camera with you that is high quality can't hurt.

    I'm not following this tablet development much, but I kind a like the "tablet idea"...
    But so far I haven't seen any tablet with USB support. Is this notion OK or I'm missing something?
  • Death666Angel - Thursday, December 1, 2011 - link

    If by USB support you mean USB host capabilities (as in, you can plug a USB stick in and read data off it), every modern tablet/smartphone I know can do that, except Apple iStuff.
    Mice, gamepads, printers etc. are a more complicated matter.
  • Stupido - Thursday, December 1, 2011 - link

    By complicated matter I guess you refer to the driver level of the OS?
    Because once you have USB host, than I guess it will be up to the OS to provide the correct drivers?
    I don't know how different are the kernels (and their corresponding driver architecture) between Android and Linux...
    I just know that Android is a fork of the standard Linux kernel...
  • Death666Angel - Thursday, December 1, 2011 - link

    Yup, driver implementation and program support was what I was getting at. :-)
    If you are interested in that sort of stuff, XDAdevelopers is always a great place for any smartphone/tablet questions of a technical nature.

    Thx! I'll check that...
