ffmpeg：普通文件名的“找不到協議”
時不時地
ffmpeg告訴我myfile.avi: Protocol not found Did you mean file:myfile.avi如果執行
ffmpeg -i myfile.avi -vcodec copy -acodec copy -pix_fmt yuv420p myfile.mp4.然後使用
ffmpeg -i file:myfile.avi -vcodec copy -acodec copy -pix_fmt yuv420p myfile.mp4失敗：file:myfile.avi: Protocol not found Did you mean file:file:myfile.avi重新啟動（通常我只是進入）後執行相同的（超出 bash 歷史記錄）可以正常
pm-suspend-hybrid工作，從 .avi 轉換為 .mp4 就像預期的那樣。任何想法可能是什麼原因以及如何解決這個問題？

我來到這個主題是為了給使用者添加一個提示，我發現如果文件名本身有’：‘會導致問題，因為某些程序會生成帶有時間戳的文件，例如“音頻12： 34:14.ogg"
對我來說，“找不到協議”錯誤是由輸出文件名中的“：”引起的。刪除它然後重新添加聽起來像是一種解決方法和不必要的複雜性。幸運的是，我能夠找到解決方案 - 只需
file:在文件名前面添加即可。例如，即使$file包含像“09:02:21”這樣的子字元串，這也會起作用：ffmpeg -i "$file" -acodec pcm_s16le -vcodec copy "file:${file:r:t}".mov在上面的命令中，在這個答案的上下文中，只有
file:部分是重要的；但是如果有人想知道是什麼，它會在 zsh shell 中從變數${file:r:t}中刪除絕對路徑和擴展子字元串。$file請注意，file:在這種情況下，輸入文件名不需要，但對於輸出文件名卻是必需的，即使兩者都包含多個“：”字元。
