網路上可以找到一些m3u8 的列表
所以今天試著在linux上直接播放 m3u8 的檔案
本來是想用VLC
但VLC載入播放清單檔時如果連不上會一直跳錯誤訊息
後來找到 smplayer
直接 開啟 檔案 載入 m3u8的列表檔後
就可以打開play list 來選擇想看的來源
很方便

今天在把raspberry 4 接到電視時
碰到聲音無法從hdmi輸出的問題
找了很多文件
試了三個OS版本
最後是使用 linux mate 才處理好
因為在音訊設定上可以直接選擇hdmi輸出
但選完後每次重開几就要再重新手動設定一次 有點麻煩
為了解決這個問題
在手動設定好後
執行以下指定
pactl list short sinks
找出目前使用的是那個輸出
找到後
接下來再開几啟動的設定加上一個開几指定音訊輸出的指令
pactl set-default-sink alsa_output.platform-bcm2835_audio.stereo-fallback
這樣每次重開就會自動重新指定音訊到hdmi輸出了

今天利用API試著從 twse 撈出資料

如果要取得msgArray裡的資料
指令如下
curl https://mis.twse.com.tw/stock/api/getStockInfo.jsp?ex_ch=tse_00882.tw|jq '.msgArray'
[

再來要報得目前的即時報價 在 "a" 這個欄位 這裡花了一點時間試
因為上一步的資料裡多了中括號 [ ]
所以指令要改成如下
curl https://mis.twse.com.tw/stock/api/getStockInfo.jsp?ex_ch=tse_0056.tw|jq '.msgArray[].a'
"34.3700_34.3800_34.3900_34.4000_34.4100_"
第一個分隔就是目前報價
