<p>Prenos: </p> <hr /> <div>[[Category: SDL]]<br /> Palm's binary sdk the &quot;Plugin Developer Kit&quot; will not be available until March 2010.<br /> <br /> In the mean time, WebOS Internals has released a full &quot;PDK&quot; for you using Scratchbox2. <br /> <br /> We ''strongly'' urge the community to standardize on this PDK until Palm releases theirs. We believe that it uses the same underlying technologies, and that it will give you both a means to port games now, and a head-start to development against the official Palm PDK in the future.<br /> <br /> Scratchbox 2 is a cross-compilation engine, it can be used to create a highly flexible SDK.<br /> <br /> As installed below, the install process uses a script which extracts the required Palm provided files from a copy of webos doctor, and downloads from other sources, and builds a complete compilation environment automatically which can compile SDL and openGLES apps for webOS. <br /> <br /> SB2 ''itself'' is totally distribution neutral but the webOS cross-compile environment is designed and tested on Ubuntu 9.10 32 bit. (At least one user in #webos-internals reports complete success running the cross compile environment in Ubuntu 9.10 64 bit after installing curl via apt-get.) <br /> <br /> The webOS Internals team ''strongly suggest'' apt-get install into that environment only for this purpose. The same installation of Sun Virtualbox which hosts the Palm SDK emulator can host an Ubuntu 9.10 server with very little effort. <br /> <br /> ==SB2 Homepage==<br /> [http://www.freedesktop.org/wiki/Software/sbox2 http://www.freedesktop.org/wiki/Software/sbox2]pdk<br /> <br /> ==License==<br /> Scratchbox 2 is distributed under LGPL version 2.1, portions are under GPL version 2. Some minor stuff is under MIT style license.<br /> <br /> == Installation on Ubuntu for WebOS PDK cross compiling ==<br /> &lt;div style=&quot;float:right; clear:right; width:30%&quot;&gt;{{Ubuntu_VM_notes_for_Windows_users}}&lt;/div&gt;<br /> ===Prequisites===<br /> Your Ubuntu installation will need the following installed. If you do not have them, run the command after the package name. You can test if they are found by just typing the command name. If it says command not found, you need to install it. <br /> <br /> {| border=&quot;1&quot;<br /> |+ <br /> |'''git''' || sudo apt-get install git-core<br /> |-<br /> |'''gcc''' || sudo apt-get install build-essential<br /> |-<br /> |'''curl''' || sudo apt-get install curl<br /> |-<br /> |'''unzip'''|| sudo apt-get install unzip<br /> |-<br /> |'''autoconf'''|| sudo apt-get install autoconf<br /> |-<br /> |'''subversion'''|| sudo apt-get install subversion<br /> |-<br /> |'''libtool'''|| sudo apt-get install libtool<br /> |-<br /> |'''wget'''|| sudo apt-get install wget<br /> |-<br /> |'''pkg-config'''|| sudo apt-get install pkg-config<br /> |-<br /> |'''gettext'''|| sudo apt-get install gettext<br /> |}<br /> <br /> <br /> If you're uncertain at all, just cut and paste the following. If they are already installed, they'll be skipped. <br /> <br /> sudo apt-get install git-core build-essential curl unzip autoconf subversion libtool wget pkg-config gettext<br /> <br /> '''Note:''' The ''make toolchain'' command and later steps will download approximately a half-gig of tools and sources from various locations. Do not start this if you do not have time for a large download. Additionally, if you already have downloaded a copy of the WebOS 1.3.5 doctor, you can reduce the download time by copying the doctor file into cross-compile/doctors/webosdoctorp100ewwsprint-1.3.5.jar . This will cause the appropriate command to skip that download. Note that codesourcery rate limts downloads and at a minimum this process will take 10 to 15 minutes irrespective of your connection speed. <br /> <br /> ====Start setup====<br /> Create a preware folder, copy the cross-compile tools into it (if you have not installed git, apt-get install git-core), and use a make script to begin the set up of the compilation toolchain. <br /> <br /> sudo mkdir -p /srv/preware<br /> cd /srv/preware<br /> sudo chmod 777 .<br /> git clone git://git.webos-internals.org/preware/cross-compile.git<br /> cd cross-compile<br /> make toolchain<br /> <br /> ====Fix mmap errors====<br /> The following commands appear redundant. They are not. The install this fixes your mmap config to fix an mmap: permission denied error, but we don't need the package itself.<br /> <br /> sudo apt-get install qemu-arm-static<br /> sudo apt-get remove qemu-arm-static<br /> <br /> : &lt;span style=&quot;font-size:150%&quot;&gt;OR&lt;/span&gt; As a workaround, if this package is not available, <br /> ::: the following commands can be executed in a root shell (sudo -s) to fix the mmap configuration to enable qemu-arm to work.<br /> <br /> echo &quot;vm.mmap_min_addr = 4096&quot; &gt; /etc/sysctl.d/mmap_min_addr.conf<br /> /etc/init.d/procps restart<br /> <br /> (note that the value should not be &quot;0&quot;. 4096 is chosen to avoid null pointer attacks.)<br /> <br /> <br /> ====Setup Scratchbox====<br /> Now, use apt-get to setup scratchbox...<br /> <br /> sudo apt-get install scratchbox2 qemu-kvm-extras<br /> <br /> ...and set it up for compiling for webOS. <br /> <br /> cd /srv/preware/cross-compile/toolchain/arm-2007q3/arm-none-linux-gnueabi/libc<br /> PATH=/srv/preware/cross-compile/toolchain/arm-2007q3/bin:${PATH} sb2-init -c /usr/bin/qemu-arm armv7 arm-none-linux-gnueabi-gcc<br /> cd /srv/preware/cross-compile<br /> <br /> Then:<br /> <br /> make stage<br /> <br /> Once this setup is complete, compiling sdl apps for webOS is very simple.<br /> <br /> ==Sample build of [[Application:ScummVM]]==<br /> <br /> Go here for simple instructions of how to build ScummVM [[Application:ScummVM#Building_ScummVM]]</div>

<p>Prenos: </p> <hr /> <div>== Theme Management API ==<br /> <br /> This is an initial attempt at hashing out a secure, reliable Theme Management API. One of the main goals is to modify as little as we can of stock Palm files. <br /> <br /> # Create a new theme folder in /media/internal/.themes/thisTheme/ <br /> # Create a new themeinfo.json file in that folder which contains the following: <br /> #* Themename: Display name for theme<br /> #* themedesc: quoted text of html for description of theme <br /> #* themethumb1: filename of thumbnail image 1 for theme <br /> #* themethumb2: ditto image 2 <br /> #* themethumb3: ditto image 3 <br /> #* themeauthor: author name <br /> #* themehome: URL of homepage for this theme <br /> #* themeversion: version number <br /> # In that new folder, place a file for each image that you intend to theme. <br /> #: The new file must be placed in the exact same relative path as before... that is to say, if the file was previously at /usr/palm/images/1.png then the new file must be at /media/internals/.themes/thisTheme/usr/palm/images/1.png <br /> #: The new file must have the same name, and be of the same type as the original file.<br /> # The themer must include a file for each CSS file that he wants to theme... <br /> #: If the css file being overridden is an application css, it must be placed in the exact same relative path as it would have been in the application. <br /> #:: If the original application was /usr/palm/applications/phone/stylesheets/phone.css the theming css must be in /media/internals/.themes/thisTheme//usr/palm/applications/phone/stylesheets/theme.css<br /> #:: the theming file must ALWAYS be called &quot;theme.css&quot;<br /> # If you are overriding one of the palm global stylesheets they must be placed in the correct place as well. /usr/palm/framework/stylesheets and be named themeXXXXX.css where XXXXX is the global stylesheet being overridden. <br /> # In your theme override stylesheets references to your images that override the default images should refer to /var/activetheme/... not to /media/internals/.theme/mytheme <br /> # When your theme is chosen as the active theme, the system will symlink YOUR theme directory to /var/activetheme.<br /> <br /> A one-time patch will be made against the framework files in /user/palm/framework which will add loading themeXXX.css after each reference to XXXXX.css and which will modify launcher so that when an application is loaded, after appname.css is loaded, theme.css will be loaded from /var/activetheme -- matching CSS classes from those files will then automatically override the previous ones from the defaults.<br /> <br /> ==Writing the theming css files== <br /> <br /> Theming css files must be &quot;sparse&quot; that is, they ONLY contain the classes being overridden not the entire global css file. So, if for example you are overriding the &quot;button_one&quot; class in the phone application css, your theme.css in /thisTheme would be /usr/palm/applications/phone/stylesheets/theme.css and would contain ONE class <br /> &lt;pre&gt;<br /> {button_one: <br /> background-image: /var/activetheme/yadayadayada/1.png<br /> }<br /> &lt;/pre&gt;<br /> '''NOTE NOTE NOTE -- I know that's wrong -- I'm trying to get an Idea out here ok? '''<br /> <br /> ==Theme Management app==<br /> * The theme management app iterates the folders in /media/internals/.themes and comes up with a list of themes folders in there. <br /> * It then opens each of the themeinfo.json files and displays a list of the available themes. <br /> * Upon tapping on a theme name a descriptive page (stolen from preware) comes up and displays the thumbnails and description and otherdata with an INSTALL button <br /> * Upon pressing install, the theme app's service symlinks /media/internal/.themes/chosenTheme to /var/activetheme <br /> *: '''(is a luna restart required at that point?) ''' &lt;-- no :&gt;</div>

Prelease for launching shell scripts. Use Flashlight App! to install it before attempting to run.<br /> &lt;br&gt;<br /> Currently stop button doesn't work.<br /> <br /> Note: Current versions of Prelease available through webOS QuickInstall and Preware no longer support the exploit to pass abritrary code, so this shouldn't work --[[User:Prenos|Prenos]] 16:59, 9 September 2009 (UTC)<br /> <br /> == ToDo ==<br /> 1.) Figure out proper way to freevideosink via a homebrew app (killing gst-launch properly) (probably will involve invoking a custom service)&lt;br&gt; '''UPDATE''': sending an INT signal seems to work? not sure if I'm missing something here... --[[User:Prenos|Prenos]] 15:14, 6 October 2009 (UTC)<br /> 2.) Mux in sound from alsasrc&lt;br&gt;<br /> :&quot;gst-launch alsasrc ! alsasink&quot; will give you sound from the mic playing back through the speakers, verifying alsasrc. It quickly loses resolution though, and starts giving &quot;can't keep up with audio source&quot; errors. --[[User:Zinge|Zinge]] 08:23, 7 August 2009 (UTC)<br /> <br /> :&quot;gst-launch alsasrc ! wavenc ! filesink location=/media/internal/downloads/test.wav&quot; will record audio no problem. --[[User:Cpcrook|Cpcrook]] 17:36, 7 August 2009 (UTC)<br /> :&quot;gst-launch camsrc ! palmvideoencoder ! avimux name=mux ! filesink location=/media/internal/downloads/foo.mts alsasrc ! mulawenc ! mux.&quot; will mux audio and video, though the timing was a bit off when I played it back. --[[User:Muchtall|Muchtall]] 18:15, 7 August 2009 (UTC)<br /> <br /> 3.) Implement preview screen (possibility: send video through palmvideosink, then to palmvideoencoder so its still accessible for preview?) '''UPDATE''': this seems semi-posible, as there are supported gstreamer elements that could &quot;tee&quot; the pipeline to 2 locations, unfortunately a custom app using palmvideosink seems unlikely as it's locked up in MediaServer --[[User:Prenos|Prenos]] 15:14, 6 October 2009 (UTC)&lt;br&gt;<br /> <br /> 4.) Get Videos app to display recorded video files (if anyone knows why the doesn't work now, please add it here, because it should work but it doesn't) '''UPDATE''': This definitely SHOULDN'T work. You're piping a RAW h264 bitstream to a file with no container. Honestly I'm suprised it plays back in totem/smplayer. My only guess is they somehow contain them during stream. I'm working on backporting qtmux, as it's the only viable solution I've come up with that would be compatible with Pre's environment --[[User:Prenos|Prenos]] 15:14, 6 October 2009 (UTC)&lt;br&gt;&lt;br&gt;<br /> 5.) Video conferencing via UDPsink? '''UPDATE''': I'm thinking theoraenc and net2stream to an icecast server. 2 way probably isn't possible, i suppose this would be more 'http video streaming' than conferencing --[[User:Prenos|Prenos]] 15:14, 6 October 2009 (UTC)&lt;br&gt;&lt;br&gt;<br /> 6.) Get 720x480@30fps working (TI claims this is possible with the current hardware). This seems to require recompiling camsrc with palm's 'capabilities template' removed or adjusted(palm offers both the base v4l2 drivers as well as their patch to compile the camsrc plugin on their opensource website). There's also a comment in palmInitMedia.js that the driver only supports up to 480x320, but v4l2 is documented to handle higher resolutions. Will also requre installing another video encoder. --[[User:Prenos|Prenos]] 20:10, 27 August 2009 (UTC) '''UPDATE''': this seems to be infeasble due to memory limitations, tons of segfaults and things. might have to do some serious buffering and framerate adjustments to get this to work. Will try with more efficient encoders --[[User:Prenos|Prenos]] 15:14, 6 October 2009 (UTC)</div>

Prenos http://wiki.webos-internals.org/index.php?title=Gstreamer&diff=6284 2009-10-06T14:29:29Z

<p>Prenos: </p> <hr /> <div>Gstreamer as installed on the Pre is version 0.10.21, along with a patch. The patch seems to do minor error handling, along with registry adjustment. The registry in Gstreamer is used to &quot;install&quot; new plugins that are added to the library (plugins are generally located in /usr/lib/gstreamer-0.10/). As of Gstreamer version 0.10, this is an automated service, no user entry is neccesary to update plugins. In fact, each time &quot;gst-inspect&quot; is ran, plugins should update automatically. For an unknown reason, Palm has decided to edit it in such a way that this is no longer the case. One theory is that Palm-built plugins were not registering correctly, so they adjusted the mechanism of the gst registry. Palm did include, however, a script to force registering manually. This is located in /usr/bin/PmMediaGstBinRegistryApp (credit to ajames for discovering this functionality).<br /> <br /> Many possibilities, including alternative audio and video filetype support (encoding and decoding), as well as video and audio streaming with the Pre as the source (icecast, etc) exist. It should even be possible to create an app to encode or recode various types of audio/video files into other formats, right on your phone.<br /> <br /> To build working (registerable) plugins, it seems you must have a very specific compiling environment that is compatible with the Pre's native environment. The same applies whether you are on an arm host or have a cross compiling environment. The following are libraries or applications that are found to be compatible with the Pre's native runtime environment. glibc 2.5 (2.6.1 however is confirmed to work for the majority of applications, 2.7 fails on gst plugin registering), glib 2.14.4 (2.0-14.4), gstreamer 0.10.21, base 0.10.21, bad 0.10.9, liboil &gt;0.3.8<br /> <br /> Additional information can be found at the [[VideoRecording]] wiki page.</div>

There's also a comment in palmInitMedia.js that the driver only supports up to 480x320, but v4l2 is documented to handle higher resolutions.

<p>Prenos: </p> <hr /> <div>Gstreamer as installed on the Pre is version 0.10.21, along with a patch. The patch seems to do minor error handling, along with registry adjustment. The registry in Gstreamer is used to &quot;install&quot; new plugins that are added to the library (plugins are generally located in /usr/lib/gstreamer-0.10/). As of Gstreamer version 0.10, this is an automated service, no user entry is neccesary to update plugins. In fact, each time &quot;gst-inspect&quot; is ran, plugins should update automatically. For an unknown reason, Palm has decided to edit it in such a way that this is no longer the case. One theory is that Palm-built plugins were not registering correctly, so they adjusted the mechanism of the gst registry. Work is currently underway (by ajames) to either edit the existing system, or create an alternate work around. This should allow developers to build and &quot;install&quot; plugins (and elements within) that are compatible with gstreamer.<br /> <br /> Once the community gets a working gstreamer plugin environment, it opens up many possibilities, including alternative audio and video filetype support (encoding and decoding), as well as video and audio streaming with the Pre as the source (icecast, etc). It should even be possible to create an app to encode or recode various types of audio/video files into other formats, right on your phone.<br /> <br /> Additional information can be found at the [[VideoRecording]] wiki page.</div>
