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.
