So its long time ago that I wrote something about Android-x86 and my Acer1825 but now I could tell, that I was not lazy in between.
I was working on builds based on the former work for froyo-x86 of arobase (we are still in contact, but he does not own the Acer1825 anymore).
I have figured out a solution for watching HD videos on my old XBOX classic. This attempt should work also for other low performance devices which are not able to render HD media standalone.
The basic idea is using UPNP (because many devices are able to use it) and an UPNP server which supports live transcoding of the media. I choose mediatomb on my debian desktop system(also available for windows…).
After you have installed mediatomb you need add some directories/media`s with the web-interface. I think it is not necessary to explain that step, because its quite easy. If someone needs support please ask. After you have added some media with HD content, in my case some movies inside MKV containers, you need to edit the configuration.
On debian mediatomb configuration is stored in /etc/mediatomb/config.xml. Open this file with an editor and do following changes inside the transcoding section. Changes are marked bold. <transcoding enabled=”yes“>
<mimetype-profile-mappings> <transcode mimetype="video/x-flv" using="vlcmpeg"/> <transcode mimetype="application/ogg" using="vlcmpeg"/> <transcode mimetype="application/ogg" using="oggflac2raw"/> <transcode mimetype="audio/x-flac" using="oggflac2raw"/> <transcode mimetype="video/x-matroska" using="vlcmpeg"/> </mimetype-profile-mappings> <profiles> <profile name="oggflac2raw" enabled="no" type="external"> <mimetype>audio/L16</mimetype> <accept-url>no</accept-url> <first-resource>yes</first-resource> <accept-ogg-theora>no</accept-ogg-theora> <agent command="ogg123" arguments="-d raw -o byteorder:big -f %out %in"/> <buffer size="1048576" chunk-size="131072" fill-size="262144"/> </profile> <profile name="vlcmpeg" enabled="yes" type="external"> <mimetype>video/mpeg</mimetype> <accept-url>yes</accept-url> <first-resource>yes</first-resource> <accept-ogg-theora>yes</accept-ogg-theora> <agent command="vlc" arguments="-I dummy %in --sout #transcode{venc=ffmpeg,vcodec=mp2v,vb=4096,fps=25,aenc=ffmpeg,acodec=mpga,ab=192,samplerate=44100,channels=2}:standard{access=file,mux=ps,dst=%out} vlc:quit"/> <buffer size="14400000" chunk-size="512000" fill-size="120000"/> </profile> </profiles> </transcoding>
I made huge progress on using my installed androidx86 on my Acer1825(build). Today I found out, how to install all google apps included synchronization of mail,contacts.. and all funny apps like google talk, maps, youtube and don`t forget the original google market!!! And I can say it works. I can’t believe, it works!
Most of you know that nice Androidx86 release from arobase for the Acer1825, but a lot of you asked for installation on hard-disk. I have done it and here comes, how it works:
First my start configuration: I had a installation of Windows7 (seldom used) (NTFS) and Ubuntu 10.10 on LVM(ext4), no free space for a new partition.
Today I have had the problem of generating my latex tables for acronyms and glossary with glossaries package and makeindex with Texmaker. The main problem is, that Texmaker only allows one makeindex command at the same time.
To solve that problem I wrote a workaround bash script, which I named makeindex_acro_glos.run
This guide is writte for my Acer 1825 but it should work on all linux devices which need a onscreen keyboard like onboard.
I got the idea of building this script from Tom/drnessie from the ubuntuforums.org (http://ubuntuforums.org/showthread.php?t=1486671&page=17), because he tried to make a improvement of my onscreen keyboard show/hide script from this post.
In my last post I explained were you found a tutorial for installing a real multitouch driver for the ACER 1825 and said I don’t know how to use these multitouch support. Thanks to Tom/drnessie who recommended ginn to me.
Ginn is a daemon which recognizes multitouch gestures with the ubuntu utouch interface and translates them to global or application specific shortcuts.
In two old posts I described, how you could use the gyro sensor of the Acer 1825 for auto rotating your screen and how you could enable and disable this feature with a special button.
