我正在使用 OMXPlayer 在無頭 Raspberrypi 上運行一些視頻。但是，加載視頻時有很大的差距，所以我想嘗試一下mpg123應該很快的。
我使用 VLC 將我的 m4v 視頻轉換為 MPG 格式。但是，當我想播放該檔案時，我總是會收到以下錯誤：
[src/libmpg123/parse.c:1204] error: Giving up searching valid MPEG header after 65536 bytes of junk.
為了進一步除錯問題，我嘗試了來自 Internet 的 mpg 檔案：
我正在使用mpg123 version 1.23.8.

uj5u.com熱心網友回復：
...該視頻的檔案名非常容易誤導，它沒有音頻。嘗試一個實際包含音頻的檔案，比如
wget "https://images.wikia.com/monchbox/images/0/01/Beep-sound.ogg"
ffmpeg -i Beep-sound.ogg beep.mpg
mpg123 beep.mpg
...如果你能被激怒，如果你能向 filesamples.com 系統管理員抱怨誤導性檔案名，以及 mpg123 開發人員抱怨 mpg 檔案不包含音頻時出現的糟糕錯誤訊息，那就太好了：o
