我使用 排程自動呼叫 python 播放影片
Raspberry Pi 4 有接螢幕

python 去指定API抓影片目錄並下載影片
使用OMXPlayer播放

每一兩天 就會OMXPlayer直接炸了
python沒有全壞就繼續在那裡背景執行
但影片早停了

定時呼叫順便當看門狗(shell)

for i in {1..12}

    #sudo pkill -f omxplayer;sudo pkill -f fbi;pkill -f SmartMiniBox.py; #預防性刪除舊的

個人建議用ffmpeg裡的ffplay，以全螢幕播放影片...

GUI跟純CLI全適用

安裝很簡單，用 sudo apt-get install ffmpeg 即可

播放器的問題是地雷，踩到了要脫身還真的難，ffmpeg是我用過最順的一個

omxplayer 很好用...
但不知為什麼,去到pi4播放得久會卡死
