想請問各位

因為想把mplayer port到arm的嵌入式板子上

所以試著去網站下載mplayer的source code來用


不過我之前沒用過mplayer,所以先不cross-compile,

試著在linux裡面直接compile試用看看

後來有compile出來mplayer的執行檔

不過想用來播放檔案的時候出現一點問題


直接打指令執行

播放mp3沒問題...不過在播放影音檔的時候

都只有聲音出來...不會跳出畫面

爬文可能是video out的問題

不過我不太知道要怎麼設定那個-vo的參數

這似乎是一個新手問題...不過還是來問問看...google辜不出什麼心得


最後附上我執行的訊息 跟我用 ./mplayer -vo help查到的東西

-vo我查到的都試過了 結果都一樣...@@

有些沒跟我說-vo參數有錯 但影像也是沒出來....


-------執行結果 (這個直接用./mplayer xxx.avi) --------------------
