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.

    Nope I hate it too.

    I'm not sure if you can hold the thing without it.

    "Somewhere to put your fingers? pfft ill trade that space for working area and hold it at the edge"

    Yes, somewhere to put your thumb. Just hold a tablet and you'll know how necessary that is.

    thumb maybe, a slight margin, but not a huge ugly border, how big are your thumbs?

    the contact area for any touchscreen running windows may need a little bar on the left, small, but tablet desktops arent left justified like windows has been since the wimp revolution..theyre centralised like a phone or a car pc front end

    No. It's impossible to use these things without a good size border. .75" seems to be about the. Indium. The Fire has about .5" border around three of the sides, and a number of reviewers have mentioned that it's too easy to touch the screen when holding it, and doing something unintentional.

    With a phone, you're holding it with one hand wrapped around the back, and up both sides. With a tablet, even a small one, you use one hand with a thumb over the edge. It's too much mental work to keep that thumb from hitting the screen. It even happens with wider borders.

    Get used to it.

    The best solution would be to make apps fully resizable, and create a dynamic bezel based on where your hands are. You just need a touch sensor around the edge and back to detect the position of your hands.

    No one should ever hire you as an ergonomic designer, then...

    Many, many times you'll have your thumbs on the front, and even if you didn't have to, it'd be more comfortable. Not the least of which is that it's a lot easier to rotate the tablet when you don't have to hold it gingerly by the edges.

    If these lawsuits keep up then that may eventually happen...

    Flippant dislike of Apple product designs makes me laugh. Apple product designers and engineers spend months and sometimes years agonizing over the details of their designs. It's quite unlike any other company on the face of the earth. Your tablet idea for an edge to edge screen simply sucks....I'm glad you don't work for Apple.
  • Omega215D - Thursday, December 1, 2011 - link

    It's not like Apple is the first and only ones to do it. It just depends on what's available at the time, the price point to be met and expectations of the product.

    I've had several well made players before the iPod came out, and extends to before the iPod Touch.
