			<content:encoded><![CDATA[<div>With the addition of video recording to the Android G1 via the Cupcake <a href="http://www.digitalwerks.org/2009/05/27/video-recording-on-g1-cupcake-update/">update</a>, there is more interest in video on the phone than ever before. Â While I&#8217;m still waiting to see some live-streaming solutions emerge for the phone, there are some new applications that help to optimize the video experience of the G1.</div>
<p></p>
<div><a href="http://dcunningham.net/encodehd/">EncodeHD</a> is a very nice program developed by Dan Cunningham that provides super simple one-click encoding of video into a bunch of mobile device friendly profiles. Â I sent Dan the specs I had discovered and put together forÂ MeGUIÂ encoding, and he very quickly was able to add a G1 profile to his program. Â UnlikeÂ MeGUI,Â EncodeHDÂ usesÂ ffmepgÂ instead of x264 as its encoding engine, but otherwise it does a great job of making a complex task very straight forward. Â It&#8217;s also very fast! Â He is still doing some tweaking to the G1 profile ofÂ EncodeHD, but I would encourage users to try it out right now and then just update when he has a new version. Â One thing to be aware of though, is thatÂ EncodeHDÂ is not very sophisticated when it comes to cropping, so if that is an issue with a video you have, you may want to useÂ MeGUIÂ or another encoding application for that. Â But if you have no Â interest in digging into the details of video compression, EncodeHD is a great option.</div>
<p></p>
<div>The other G1 application I&#8217;m excited about is the <a href="http://www.hyperaware.com/android/video-player/">Act 1 Video Player</a>, an actual Android app that can be downloaded from the Android Market. Â There are other video players available for the G1, but this is easily the most full featured and sophisticated. Â I really like the sophisticated user interface that blows other players out of the water. Â In fact, I liked the program so much that I purchased the $.99 full version (there is a free lite version as well), which makes it the first for pay Android application I have ever bought. Â Can&#8217;t think of higher praise than that. <img src='http://www.digitalwerks.org/wp-includes/images/smilies/icon_wink.gif' alt=';)' class='wp-smiley' /> </div>
<p></p>
<div>WithÂ EncodeHDÂ and the Act 1 Video Player any Android user with a desire to maximize the phone&#8217;s video capabilities would be off to a very strong start. Â Now if we can only getÂ QikÂ to provide streaming, we&#8217;ll be in business&#8230;</div>

After a few delays, the 1.5 (Cupcake) update for the Android G1 phone from T-Mobile has arrived. Â Impatient as I am, I followed the instructions from the <a href="http://androidguys.com/?p=5235">AndroidGuys</a> and forced my phone to update, although I think I only gained about 12 hours ultimately. Â In any case, it&#8217;s a big step forward for the phone and the Android platform, with some great UI improvements, including the much discussed virtual keyboard.</p>
<p>For me, however, the most exciting new development is the implementation of video recording on the G1. Â After the phone is updated a new app appears, &#8220;Camcorder.&#8221; Â The use is fairly simple, just point and shoot. Â There are two quality settings, &#8220;Low&#8221; and &#8220;High,&#8221; with the Low setting designated for &#8220;MMS&#8221; usage. Â One nice feature is that video recording is integrated into the Camera app, and the user can switch from video recording to still photography with the click of one button.</p>
<p>The captured video uses the .3gp container format for the h.263 video codec. Â Audio is labeled as &#8220;samr&#8221; and is the standard 3gp audo codec of AMR-Narrowband. Â Using the &#8220;High&#8221; setting the video resolution isÂ 352&#215;288 and the bitrate looks to be around 350-400 kbps. Â &#8221;Low&#8221; has a resolution ofÂ 176&#215;144 and bitrate around 200 kbps.</p>
<p>The Camcorder app allows for very easy video sharing with one-touch email, MMS, and YouTube integration. Â The YouTube integration works very well, at least with the relatively small size video files I have tested with so far.</p>
<p>How does the video look? Â Well, not great. Â The camera on the G1 is not particularly good, and turning it into a video camcorder has not magically improved it. Â That said, the video recording on mobile devices is generally not very good from a visual quality standpoint generally, at least with the current generation of in-device cameras. Â Motion is pretty jerky, the colors are not great, and the audio quality, while in stereo which is nice, leaves a lot to be desired. Â Still, the ability to capture video on the fly and get it uploaded to YouTube very, very easily has a lot of promise for the G1 and future Android phones. Â The killer app may be, though, live streaming. Â I am very hopeful that <a href="http://www.qik.com/">Qik</a> can get implemented on the G1 sooner rather than later. Â Broadcasting live has a number of great potential uses that rely far more on immediacy a mobile allows rather than the quality it cannot currently provide.</p>

<p>As a follow up to my previous <a href="http://www.digitalwerks.org/2009/01/15/a-few-weeks-with-an-android/">posts </a>about the <strong>G1 Android phone from T-Mobile</strong> (and Google!), and from a personal interest, I wanted to gather as much information about the phone&#8217;s video capabilities as I could. Â In general, there has not been much information available about the detailed video specifications of the G1, which has proven somewhat <a href="http://blogs.amd.com/patmoorhead/archive/2008/10/27/unlock-some-secret-of-the-android-g1-video-encode-decode.aspx">frustrating </a>to those people interested in using it as a portable viewing device.</p>
<div>At the basic level, the G1 can decode the <a href="http://en.wikipedia.org/wiki/H.264">h.264</a> codec in .mp4 and .m4v container formats. Â If you are familiar with iPod/iPhone video capabilities, you should recognize those specs, as they are pretty close to what Apple is using. Â And that is likely not a coincidence, as my guess is that video was somewhat neglected in the G1&#8242;s development and choices were defaulted to an already established format. Â I assume that video as a category was overlooked for a number of reasons: unlike the iPhone with iTunes, there is no established commercial entity selling video content for the G1. Â But probably more important is the fact that Android isÂ a platform targeted for a number of different hardware devices, and not just phones but MID&#8217;s, netbooks, etc. It probably did not make a lot of sense for the Android developers at Google to put a lot of time into a video format that may only be specific one device, the G1. Â And from the other direction, the actual manufacturer of the phone, HTC, I suspect probably handed everything over to Google, since video can be something of a headache for phone makers without a lot of expertise in this area. Â In other words, G1 users were kind of left on their own when it comes to video, something pretty clearly shown by the fact that the phone did not even come with a native video player application! Â A couple popped up almost immediately, but they are not particularly sophisticated or polished.<br />
Â </div>
<div><span id="more-218"></span>So, reaching back to my days with the <a href="http://www.divx.com/en/partner/certified-programs">DivX Certification</a> lab, I devised to determine what, in fact, the video capabilities of the phone actually are and then to come up with an encoding profile that would take the most advantage of what the G1 offers. Â I created dozens of test clips with a wide variety of encoding parameters and tried to play them on the phone. Â Once I had learned what the G1 can and cannot play, I started looking at which options provided the best compression compromise between size of file, quality of image, and speed of encoding process. Â Dozens of PSNR and SSIM tests later, I had some preliminary answers. Â Usually, a compressionist can only have two of the three (quality, size, and speed) but must make sacrifices on the third. Â In my case, I favored quality and speed, without too much attention paid to size since with the G1 we are not limited by a specific medium size (i.e. we are not trying fit a file on a 700MB CD or something similar to that. Â A G1 user can fit however much video they want on to whichever size microSD card they have. Â I recently purchased an 8GB card from <a href="http://www.frys.com/">Fry&#8217;s</a> for less than $20, which provides a great deal of space and does not make size concerns primary for me. Â Your mileage may vary, of course.<br />
Â </div>
<div>It turns out that the G1&#8242;s capabilities are pretty similar to later generation iPods, iPhones and Zunes. Â H.264 video on the G1 needs to conform to the Baseline Profile and the 3.0 Level, which govern some of theÂ impermissibleÂ encoding options like CABAC and B-Slices, that are powerful options but also drastically increase the complexity of the file and the power needed to decode the video content. Maybe even more crucially, G1 video has to be follow very strict resolution limits, as no video can be wider than <strong>480</strong> pixels across and no higher than <strong>368</strong> pixels. Bitrate does not appear to be nearly as strict. Â I&#8217;ve gotten the G1 to play files with surprisingly high bitrates, up to 2000 kbps, but that is generally way overkill for files with sub-SD resolutions.<br />
Â </div>
<div>In order to make my findings useful, I created a profile for the encoding application <a href="http://en.wikipedia.org/wiki/MeGUI">MeGUI</a>, considered to be the pre-eminent solution for high quality encoding of h.264 video (using the amazing <a href="http://x264.nl/">x264</a> implementation) into .mp4&#8242;s or .mkv&#8217;s (mkv, the <a href="http://www.matroska.org/">matroska</a> container format is the accepted standard for high def x264 video among current file traders but is not currently supported on the G1). Â Barring any hidden bugs I&#8217;ve missed, myÂ <a href="http://www.digitalwerks.org/x264%20Device-Android%20G1.zip">G1-Android profile</a> should become available for MeGUI auto-updates in the future, or you can download and install it yourself right now. Â I also checked with the lead developer of x264 to make sure the profile made sense from a compression standpoint, so I am fairly confident in it. Â But test it out for yourself and see if it meets your particular needs. Â If you are not interested in using MeGUI, you can just read the profile as an XML file and take the encoding settings and apply them manually in whichever application you prefer (Handbrake, Ripbot, etc.).<br />
Â </div>
<div>One reminder, when using MeGUI you will need to create an Avisynth script first, in which you will need to re-size the video to Â 480&#215;368 or below. Â You should also <strong>crop </strong>and <strong>de-interlace</strong> the video if necessary at that stage. Then MeGUI can use the G1 Android profile to do the actual encoding.<br />
Â </div>
<div>You will also notice I did not say much about audio, but that is pretty clear for the G1 encoders should stick with MeGUI&#8217;s Nero AAC LC 96 kbps profile. Â That will be more than sufficient for portable watching, imo.</div>

			<content:encoded><![CDATA[<p><img class="alignnone" title="AVC in Windows 7 beta" src="http://www.digitalwerks.org/wp-content/uploads/windows7_AVCa.png" alt="mkv?" /></p>
<p>An interesting bit of news from the <a href="http://forum.doom9.org/">doom9 </a>forums. Â As anyone who is testing the Windows 7 beta has discovered, and as the above photo shows, Microsoft is breaking with their tradition and including more codec support in the upcoming Windows bundle. Â Previous Windows versions did not even include MPEG-2 decoding, which proved to be quite mystifying to many users trying to watch a DVD in their computers for the first time. Â And, needless to say, Microsoft stayed far away from any of the more esoteric codecs, including the key MPEG-4 ASP implementations such as DivX and Xvid. Â </p>
<p>However, the beta of Windows 7 includes the ability to play back DivX, and Xvid, and even the next generation MPEG-4 AVC, better known as h.264. Â Why is this important? Â A couple things. Â First, if anybody needed further proof that VC-1 is essentially dead in the water, this is another nail in its coffin (to mix macabre metaphors). Â Secondly, and more importantly, it appears that Microsoft is jumping on the bandwagon of broad interoperability, allowing Windows users to play back a range of video formats right out of the box, something that will surely be a boon to less sophisticated users who just want to be able to watch something without having to even know what a codec is, much less a container format, audio stream, etc.</p>
<p>Even more intriguing is the news that Microsoft may be working on an implementation of the matroska container, or mkv for Windows 7 (according to madshi and haali on doom9). Â For the file-trading community, this is quite significant. Â H.264 has a ton of &#8220;legitimate&#8221; uses today, notably in higher quality Flash videos on YouTube and elsewhere. Â MKV however, is almost exclusively used currently by pirates, particularly those sharing HD video. Â Blu-Ray rips and high def TV captures are generally distributed as x264 encodes with AC3 audio in mkv containers (both 720p and 1080p), and while HD video content is still a small minority of what is shared relative to standard def video, it is growing and is likely to become the dominant format before long. Â Maybe Microsoft is just getting back at the movie studios that went with Blu-Ray instead of the MS-backed HD-DVD formats, but regardless, it would be good news if mkv support signaled that Microsoft was thinking about their users first, and video business strategies second.</p>
