3.XBMC support

Download XBMC source code and enable CrystalHD support then build.
It works great ...

PS : Do not get xbmc form apt...

4.Gstreamer plug-in
The Crystal HD gstreamer plug-in is bcmdec
In fact, it's not work ...

$ gst-launch playbin2 uri=file:///home/steve/video.mp4
Setting pipeline to PAUSED ...

Then nothing happen ...

依據以下的link做修改, Crystal HD gstreamer plug-in works
http://git.wilsonet.com/crystalhd.git/?a=blobdiff;f=filters/gst/gst-plugin/src/gstbcmdec.c;h=c321e27bba831bf99197f75454e7dde8ec36d78a;hp=1fd2eccc23d753d047b20bc076377ebcb57c4838;hb=1f293c968e5ab8dad3ad0c3ceefa91cbb1bcce63;hpb=a8e27b2203eb2c1f0266176f5c70d8c5b6102c76

totem 播放mp4 h.264 with Crystal HD works

GIT 雜七雜八的問題及解決

1.其他人push過後就不能push了

gigijoe@gigijoe-desktop:~/DSPG8181$ git push
To git@localhost:DSPG8181.git
! [rejected]        HEAD -> master (non-fast forward)
error: failed to push some refs to 'git@localhost:DSPG8181.git'

也不能pull了

gigijoe@gigijoe-desktop:~/DSPG8181$ git pull
You asked me to pull without telling me which branch you
want to merge with, and 'branch.master.merge' in
your configuration file does not tell me either.   Please
specify which branch you want to merge on the command line and
try again (e.g. 'git pull ').
See git-pull(1) for details.

If you often merge with the same branch, you may want to
configure the following variables in your configuration
file:

    branch.master.remote =
    branch.master.merge =
    remote. .url =
    remote. .fetch =

See git-config(1) for details.

git config branch.master.remote origin
git config branch.master.merge refs/heads/master
git checkout master
git reflog
git pull
git push

另一個解法(沒試過)

git pull origin master

2.沒事整理一下
git fsck --full

3.維護資料庫 (會跑一陣子,用很多記憶體)
git gc

GIT Server 架設 (使用gitosis)

參考資料
http://scie.nti.st/2007/11/14/hosting-git-repositories-the-easy-and-secure-way

http://ao2.it/wiki/How_to_setup_a_GIT_server_with_gitosis_and_gitweb

http://blog.agdunn.net/?p=277

以參考資料其實很容易就能把git server搞定.
這邊就只紀錄一下流程

< Server Side >

git clone git://eagain.net/gitosis.git

cd gitosis/

sudo apt-get install python-setuptools
sudo python setup.py install

sudo adduser --system --shell /bin/sh --gecos 'git version control' --group --disabled-password --home /home/git git

請由 Local Side 產生KEY id_rsa.pub 並存放到 Server Side

ssh-keygen -t rsa

會在$HOME/.ssh/ 產生 id_rsa id_rsa.pub

複製到Server Side /tmp

sudo -H -u git gitosis-init < /tmp/id_rsa.pub
sudo chmod 755 /home/git/repositories/gitosis-admin.git/hooks/post-update

< Local Side >

gitosis運用相當巧妙的方式管理git server.
gitosis 本身就是git server中的project.所以必須先從local side取出gitosis的副本.
透過編輯這個副本並上傳來管理所有的user & project.

git clone git@192.168.168.70:gitosis-admin.git

cd gitosis-admin

編輯gitosis.conf

增加一個新的Repository,格式如下

[group $REPOSITORY]
writable = $PROJECT


members = $USER

Commit new repository

git commit -a -m "New Repository"

git push

結果有Warning如下

warning: You did not specify any refspecs to push, and the current remote
warning: has not configured any push refspecs. The default action in this
warning: case is to push all matching refspecs, that is, all branches
warning: that exist both locally and remotely will be updated.  This may
warning: not necessarily be what you want to happen.
warning: 
warning: You can specify what action you want to take in this case, and
warning: avoid seeing this message again, by configuring 'push.default' to:
warning:   'nothing'  : Do not push anything
warning:   'matching' : Push all matching branches (default)
warning:   'tracking' : Push the current branch to whatever it is tracking
warning:   'current'  : Push the current branch

To git@192.168.168.70:gitosis-admin.git
   1cfd916..4f2becf  master -> master

我找到的解決方式是

git config --add push.default current

到這邊基礎的設定已經完成,接著要實際將project同步到git server

首先到project source code目錄下

cd S3C6410

git init

git remote add origin git@192.168.168.70:s3c6410.git

將希望的目錄加入

git add android_kernel_smdk6410

git commit

實際將資料上傳

git push origin master:refs/heads/master

會看到以下的message

gigijoe@gigijoe-laptop:~/S3C6410$ git push origin master:refs/heads/master
Counting objects: 22134, done.

To git@192.168.168.70:s3c6410.git
* [new branch] master -> master
gigijoe@gigijoe-laptop:~/S3C6410$

< Local Side >

新增user 的方式
進入gitosis-admin目錄中編輯gitosis.conf.加入$USER1

[group $REPOSITORY]
writable = $PROJECT


members = $USER $OTHER_USER

接著由user產生key並將id_rsa.pub並重新命名擺放到
keydir/$USER1.pub

把檔案加入gitosis
git add keydir/$USER1.pub

更新並上傳
git commit
git push

之後就可以用 git clone 的方式取得 project

gigijoe@gigijoe-laptop:~/gitosis-admin$ ls keydir/
gigijoe@gigijoe-desktop.pub gigijoe@gigijoe-laptop.pub
gigijoe@gigijoe-laptop:~/gitosis-admin$ git add keydir/gigijoe@gigijoe-desktop.pub
