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來用我是用VMWare裝Ubuntu7.1 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) -------------------- MPlayer 1.0rc2-4.1.3 (C) 2000-2007 MPlayer Team CPU: Intel(R) Core(TM)2 CPU 6420 @ 2.13GHz (Family: 6, Model: 15, Stepping: 6) CPUflags: MMX: 1 MMX2: 1 3DNow: 0 3DNow2: 0 SSE: 1 SSE2: 1 Compiled for x86 CPU with extensions: MMX MMX2 SSE SSE2 Playing tttt.avi.
