I am trying to invoke the ffprobe.exe file from the resources in Visual Studio. I find this answer on SO and tried to apply it to ffprobe. But I cannot load the bytes to assembly. But my code throws an System.BadImageFormatException: Bad IL Format.
I googled the error message and found that it normally indicates that the binary is corrupt. I made sure that the loaded bytes are identical to the bytes of the ffprobe.exe file from my resources, as this answer suggested. I wrote the bytes to a file and then compared it with the original file using the comp command.
When calling the ffprobe.exe file through the command line, it works perfectly. So I am sure it is not corrupt.
Here is what I tried:
object ob = Properties.Resources.ffprobe;
var ffprobeBytes = (byte[])ob; // ffprobeBytes is identical to ffprobe.exe in resources
var ffprobeAssembly = Assembly.Load(ffprobeBytes); // this line throws the Exception
var ffprobeEntry = ffprobeAssembly.EntryPoint;
var ffProbeObject = ffprobeAssembly.CreateInstance(ffprobeEntry.Name);
string[] parameters = { filePath, "=show_streams", "-print_format xml", "-loglevel fatal" };
var result = ffprobeEntry.Invoke(ffProbeObject, parameters)
The BuildAction of the resource file is Embedded Resource and Copy to output directory is set to Copy always.
Does anyone have an idea what could be the reason for this Exception?
