Question

试图将.mov转换为.mp4。在stackoverflow上尝试了各种建议代码，但似乎无济于事。

`...muxer does not support non seekable output [48] => Could not write header for output file #0 (incorrect codec parameters ?): Invalid argument [49] => Error initializing output stream 0:0 -- [50] => Conversion failed! ) 1`

我尝试了各种编解码器属性，例如ac3，aac，libvo_aacenc

exec('
/usr/local/bin/ffmpeg -y -i https://***.***.com/assets/regions/region-1/input.mov' . 
' -c:a ac3 ' 
. 'https://***.***.com/assets/regions/region-1/output.mp4' 
. ' 2>&1', $out, $res);

$modx->log(modX::LOG_LEVEL_ERROR, print_r($out));
$modx->log(modX::LOG_LEVEL_ERROR, $res);

return true;

这是我的自定义批次，可以通过保留文件创建日期将我的mov无损地转换为mp4：

@echo off
SETLOCAL ENABLEDELAYEDEXPANSION

for /d %%D in (*) do (
    for %%B in ("%%D\*.mov") do ( 
        echo %%B
        if not exist "%%B.mp4" (
            ECHO Last-Modified Date   : %%~tB
            ffmpeg -y -i "%%B" -vcodec copy -acodec copy "%%D\%%~nB.mp4"
            powershell -Command "& { (Get-ChildItem %%D\%%~nB.mp4).LastWriteTime = (Get-ChildItem %%B).LastWriteTime ;}"
        )
    )
)

ffmpeg将mov转换为mp4
