關閉APP後再進行FFMPEG操作會無法讀取檔案

[CiaShangLin]

我先對一個mp4輸出成m3u8且加密
ffmpeg -i ${mp4FilePath} -codec: copy -start_number 0 -hls_time 10 -hls_key_info_file ${keyInfoFilePath} -hls_list_size 0 -f hls ${m3u8FilePath}
然後m3u8轉回mp4
ffmpeg -allowed_extensions ALL -i ${m3u8FilePath} -codec copy ${decryptMp4Path}
錄完影片當下做上面兩個操作都沒問
但是把APP關掉後再做m3u8追回mp4操作時就會報錯
看起來是沒辦法讀取output0.ts,實在沒什麼頭緒所以上來問一下
