南部的好天氣

今年回鄉下回到屏東萬丹，許久沒感受到鄉下環境，純樸自然的生活型態，夜晚的晚風含著田園味，獨棟式的建築風格以及南部的好天氣，在在都吸引著我。 其他不談，許多親人朋友大都在北部我想是最主要對於遷移南部這個想法來說的一個適應上的問題。

萬丹的紅豆餅，潮州的泡麵早餐以及燒冷冰和旗魚黑輪，在一天內吃到真是太讚啦!!!
於不預期傳說中的城堡聚會參一腳的我感受到了Mini cooper在南部的精神了! Mini Cooper，硬式小跑車，精緻得洽到好處的藝術品。 好吧，我算是沒看過城市獵人

2010 の第一走

2009說掰掰了，2010的到來，實在讓我對2009過得之快感到些許惶恐。也期許之後的跨年能夠好好計劃一下。(跨年的點，可到國外或是中南部)

其實今年的天氣實在不怎麼樣，但難得的假期，還是要出去動一動，往大溪方向的旅程一直被擱著，不知道擱多久了，今天終於出發，由老鷹領頭，前往關西橘子園，為今年的第一次出門。

上台三線後，一路只能說可以用「好走」來形容，嗯，或可說是「行雲流水」。沿途的風景再再的吸引我的目光，可惜騎得有點快。走了15公里經台三線來到大溪老街，進入了鄉村區域，看到的房子皆是透天矮房，不覺得能看到三樓以上的房子，這就是鄉村，不管是房子還是人，都可感受到鄉村味。

沿路有許多支線，也有許多風景點，往復興鄉，石門水庫，慈湖，桃源仙谷等，以及許多我還未知的，不勝枚舉，只能另找時間再來晃晃了。

到了老鷹的橘子園，為第二次的到來，這次也多認識了橘子的種類，有椪柑，年柑，茂谷柑，對我來說實在很不好記。來到這邊走走，看著寬闊的野地，深呼吸，著實會讓人產生一些暇想，因為這裡的好空氣，實在是不錯。這裡耕農者可能就是一生在同一塊土地上耕種吧。看到隔壁有別人的菜，雖然四下無人，心裡想偷但不能偷，我沒有在玩開心農場。

照幾張照片來紀念一下。

讚!

Recently

Sometime I feel like I need to slow down my pace and my mind and now the time it is. Either for quiet thinking, intending to watch more or thinking about changing something. As you can see, I am a lazy blogger and not a good writer. Passion is the momentum for anything you want to do and it's the best gift.

Here are something about my work recently. Write it down here for arrangement.

It's about 0xdroid project. I have done implementing Camera HAL for usb camera. For this, I need to have some concept about V4L2 in kernel. It's related to V4L2 Video In. Though camera is more complicated cause it can be greatly performance related when it comes to embedded device. For most product design, the camera sensor module is connected with the camera interface of the SOC. Thus in this manner, most cases there will be closed library provided by the SOC vendor for doing some effect control and performance related tasks.

When doing video recording with the camera, colorspace conversion for encoding and for preview on the screen to make the acceptable frame rate is really critical, especially when the resolution is high. Better situation will be more task can be handled by hardware. For taking picture, it would be better if the hardware can do scaling and jpeg encoding, etc. For previewing and video recording, it also would be cool if we don't need to do heavy colorspace conversion in host software side by hardware conversion(YUYV to YUV420(sp) or RGB) and Overlay support.

Overlay is cooperated with V4L2 video out part. Overlay verifying and could be used by Camera HAL or multimedia video playback is important.

More ahead. Though I need to let myself know what's the value and getting prepared.

Off topic here in this post, most importantly, Glad and excited that we have a third release, beagle-donut-0x3.

Using Overlay on beagleboard

Recently I am trying to make 0xdroid use YUV Overlay in OMAP3 on beagleboard to play video. The purpose is utilizing the overlay in DSS system to accelerate by getting rid of the effort of the composition of different layers on software side and colorspace conversion to RGB.

For achieving this, we should get a libopencorehw module for opencore in Android. The implementation of libopencorehw can use the video-out driver, a V4l2 provider to interface DSS, like in TI's omapzoom tree. Unfortunately this way stuck me for a while, either there has problem in video-out driver or in TI's liboverlay.

After figuring out for a while, we met up another way for this, making libopencorehw use DSS ioctl directly. So we rewrite libopencorehw as simple as it looks and here is the new libopencorehw in 0xdroid. This way is more lightweight and easier to me. Welcome to try.

立燈入手

昨天去Ikea敗了一個立燈，就來寫一篇入手心得文做紀錄吧！
這款立燈其實是阿六介紹的，之前就有想買立燈，聽到六哥的介紹後，隔天就衝去逛Ikea 了！
買回來之後，帶回我在新店的住處，開始組裝！組裝是很輕而易舉的。
當我組裝完最後上面的燈泡後，打開開關，心裡一陣激昂。真相如下




我只先開了 25w 省電燈泡上面那一顆， 當場整個不一樣，夠power，而且柔合。
接著再加開小顆40w那顆，整個房間並沒有再亮很多的感覺，但是如果對著小顆那顆看的話，會有熱的感覺，看書覺得沒問題。這兩顆燈泡的搭配，整個光的顏色感覺非常好。整支燈管白色系，也具有現代感。配上牆壁的白色還不賴。燈泡的選擇似乎是影響使用感覺的關鍵，燈罩的顏色和材質也許也有關係。整體感覺，讚的啦!
