We are developing at Unity.
I wanted to install ffmpeg in the OSX app, so I installed ffmpeg on the macPC and
We have created the following code.
private IEnumerator ffmpeg (string a_path)
{
input="\"+a_path+"\";
output="\"+UnityEngine.Application.persistentDataPath+"/work/"+"hoge.mp4"+"\";
string ffmpegExePath="ffmpeg";
Process process = new Process();
US>string option="-i";
option+=""+input;
option+="-vf";
option+="scale=480:270";
option+="-an";
option+="-preset everyfast";
option+="-tune film";
option+="-crf23";
option+="-threads2";
option+=""+output;
string l_cmd =ffmpegExePath+option;
process.StartInfo.FileName="/bin/bash";
process.StartInfo.Arguments="-c\"+l_cmd+"\";
process.StartInfo.CreateNoWindow=true;
process.StartInfo.UseShellExecute=false;
process.StartInfo.RedirectStandardError=true;
process.StartInfo.RedirectStandardOutput=true;
process.EnableRaisingEvents=true;
process.ErrorDataReceived+=newDataReceivedEventHandler(ProcessErrorDataReceived);
process.OutputDataReceived+=newDataReceivedEventHandler(ProcessOutputDataReceived);
process.Exited + = new EventHandler (ProcessExited);
process.Start();
process.BeginOutputReadLine();
process.BeginErrorReadLine();
}
However,
/bin/bash:ffmpeg-i'/Users/hoge/dev/unity/Video Test 5% u20106 Compressed.mp4'-vf scale=480:270-an-preset veryfast-tunefilm-crf23-threads2'/Users/hoge/Library/Application Support/HOGEOgure/HOwork: Application
You will receive an error.
"When I copied the command from ""ffmpeg-i"" and checked it at the terminal, I confirmed that ffmpeg will start."
When I changed l_cmd to "ffmpeg-version" and tried to see if I could check the version, it replied "/bin/bash:ffmpeg:command not found" and
You may not recognize ffmpeg as a command.
How can I call ffmpeg here?
We are currently checking on the Unity emulator.
The Unity version uses 2020.3.1 f1.
Thank you for your cooperation.

The installed ffmpeg can now be called, so I tried putting the downloaded binary file in the StreamingAssets folder, but the permission denied came out and I couldn't start it.
Do you know what this is?
string ffmpegExePath=Application.streamingAssetsPath+"/KirinUtil/ffmpeg_mac/ffmpeg";
tried to change to .
Thank you for your cooperation.
string ffmpegExePath="ffmpeg";
Why don't you rewrite the ffmpeg in to a full path that you can get in which and so on?
(I don't know how it was installed, for example
/usr/local/bin/ffmpeg
and so on.
