我正在创建一个应用程序，允许用户上传视频文件，一旦他们这样做，它会将它们全部转换为 .mp4（它还执行其他一些操作，但由于代码的第一部分在有机会到达其他东西，每个过程都非常相似，我们只讨论这个问题）。
用户提交后，它会被发送到 GameController@store。下面是来自控制器的代码示例（由于有问题而不断发回给我的代码示例）：
$process = new Process(env('APP_FFMPEG', 'ffmpeg') . ' -i ' . $fileURL . ' -f mp4 -vcodec libx264 -preset medium -profile:v main -c:a aac -movflags +faststart ' . $newFileName . ' -hide_banner');
$process->setTimeout(360);
$process->setIdleTimeout(60);
$process->run();
if (!$process->isSuccessful()) {
throw new ProcessFailedException($process);
}
我正在使用 Symfony Process() 类来运行 FFMpeg 转换。奇怪的是，当我用 1 或 2 秒的视频运行这个视频时，它运行得很顺利。对我来说，这排除了路径问题、权限问题等问题。多种文件类型都可以使用，只要它们非常短。一旦我放入一个大约 1 分钟的视频，它就会返回：
The process "/usr/local/bin/ffmpeg -i http://localhost/storage/team_1_folder/game_26/team_1_game_26_vid_1.mp4 -f mp4 -vcodec libx264 -preset medium -profile:v main -c:a aac -movflags +faststart storage/team_1_folder/game_26/convertedVideo_1.mp4 -hide_banner" exceeded the timeout of 360 seconds.
现在，请注意它显示“超时 360 秒”。这是因为我还编辑了所有可能的超时约束，以及我能想到的文件大小约束。这是我所做的：
-更改了 php.ini（在我的 MAMP 安装中）值：
--max_execution_time = 300（默认为 30）
--memory_limit = 1280M（默认为128）
--post_max_size = 800M
--upload_max_filesize = 3200M
-max_input_time=300
-在 GameController 中（上面的代码）
--$process->setTimeout(360);
--$process->setTimeout(360);
毕竟，对于一个大文件，事情只会停滞我在超时事情上设置的 6 分钟，然后发送错误。 FFmpeg 只是停止运行，还是进程问题？谁知道呢。围绕这些事情的错误只是非常模糊。
我已经标记了 Laravel、PHP 和 FFmpeg，希望有人能认识到这个问题。我知道 Process() 向我发送了错误，但由于它向我发送了超时，所以我不知道出了什么问题。
我不排除任何可能性，所以请给我一些想法，甚至是疯狂的想法！
编辑 这是报告的输出。我剪掉了其中一些，因为结尾部分变得重复并且实际上有 1000 行：

经过一天的头撞墙后，我今天早上醒来并找出了我的问题。
我的错误很简单，因为我没有足够了解 FFMPEG 的局限性。完成我上面订购的转换需要很长时间。我现在正在自己的终端上运行这个东西，天哪，这确实需要一段时间。对于一个 5 分钟的视频，它是在第 13 分钟并且还在计数。
如果其他人偶然发现了这一点，只需确保您了解在 Process() 命令中运行的程序，并思考您要求它执行的操作是否合理。
我也面临着 ffmpeg 的问题。我不确定它与你有关，但我很绝望，因为我不知道问题是什么。你看，我正在尝试在我的视频上绘制一些数据，例如绘图盒。一秒内需要在视频上绘制 17 个点，因此如果视频为 12 秒，则整个视频包含 204 个要绘制的点。我尝试向 ffmpeg 发送命令。它在 6 秒之前工作正常，但在 7 秒或更长时间后就不行了 - 为什么会这样呢？是因为ffmpeg的限制吗？
