Ошибка FFmpeg: «не удалось найти закодированные параметры» ⇐ C#

[Anonymous]

При запуске ffmpeg -i в консольном приложении C# с использованием Process для некоторых файлов процесс зависает и работает вечно:

Код: Выделить всё

var oInfo = new ProcessStartInfo("ffmpeg.exe", "-i 176d2819-f1da-44eb-b33b-94eb1448194b.mov");
oInfo.UseShellExecute = false;
oInfo.CreateNoWindow = true;
oInfo.RedirectStandardOutput = true;
oInfo.RedirectStandardError = true;

string output = string.Empty;
StreamReader srOutput = null;

// Run the process
Process proc = Process.Start(oInfo);
proc.WaitForExit();
srOutput = proc.StandardError;
output = srOutput.ReadToEnd();
proc.Close();

Запуск из командной строки:

ffmpeg.exe -i 176d2819-f1da-44eb-b33b-94eb1448194b.mov

получается ошибка, указанная в приведенном ниже выводе.
