• Installation of FFMPEG for Python in WIndows

  10 février 2024, par user3587175

  I'm trying to use this python video converter and I couldn't even run the test. I read in the manual that I had to install FFMPEG separately so I did (I created the folder in C :\, the enviroment variable "path" and tested it and worked) but still doesn't work.

  



  When I run the command :

  



  python setup.py test


  



  I get this :

  



  Traceback (most recent call last):&#xA;  File "setup.py", line 51, in <module>&#xA;    packages=[&#x27;converter&#x27;],&#xA;  File "C:\Python27\lib\distutils\core.py", line 151, in setup&#xA;    dist.run_commands()&#xA;  File "C:\Python27\lib\distutils\dist.py", line 953, in run_commands&#xA;    self.run_command(cmd)&#xA;  File "C:\Python27\lib\distutils\dist.py", line 972, in run_command&#xA;    cmd_obj.run()&#xA;  File "setup.py", line 20, in run&#xA;    raise Exception(&#x27;tests failed&#x27;)&#xA;Exception: tests failed&#xA;</module>

  



  When I run this example code :

  



  from converter import Converter
c = Converter()

info = c.probe('test1.ogg')

conv = c.convert('test1.ogg', '/tmp/output.mkv', {
    'format': 'mkv',
    'audio': {
        'codec': 'mp3',
        'samplerate': 11025,
        'channels': 2
    },
    'video': {
        'codec': 'h264',
        'width': 720,
        'height': 400,
        'fps': 15
    }})

for timecode in conv:
    print "Converting (%f) ...\r" % timecode


  



  I get this :

  



  Traceback (most recent call last):&#xA;  File "C:\Users\USER\worspace_pyth\cosa\prueba1.py", line 3, in <module>&#xA;    c=Converter()&#xA;  File "C:\Python27\converter\__init__.py", line 27, in __init__&#xA;    ffprobe_path=ffprobe_path)&#xA;  File "C:\Python27\converter\ffmpeg.py", line 345, in __init__&#xA;    raise FFMpegError("ffmpeg binary not found: " &#x2B; self.ffmpeg_path)&#xA;converter.ffmpeg.FFMpegError: ffmpeg binary not found: ffmpeg&#xA;</module>

  



  I can't understand what else I need to do for this to work. Thanks for your help.

• Videos to jpg image ffmpeg error av_interleaved_write_frame

  26 mai 2021, par Loic Bch

  I'm making a program in c# in which I'm using ffmpeg to cut video into frames.
I'm doing it this way in my program :

  


  ffmpegPath = "C:\\Program Files (x86)\\ffmpeg\\ffmpeg32.bat";
string videoPath = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments), "video.avi");

Process process = new Process();
            process.StartInfo.FileName = ffmpegPath;
            process.StartInfo.Arguments = @"-i " + videoPath + " -qscale:v 2 image%03d.jpg";
            //process.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
            process.Start();   // On cut la vid avec ffmpeg 


  


  This code works perfectly fine in debugging mod and display all my images
Now I want to make a setup to install the program, so I'm using InnoSetup to make a setup but when I install the program and try to run the same code it display the command prompt with ffmpeg error :
"cannot display image2.jpg : av_interleaved_write_frame() : I/O error occurred
ffmpeg error

  


  if someone can help me on why I'm getting this error in release and not in debug mode ? Why ffmpeg can't execute the request correctly after the setup since I'm changing nothing ?

  


  I already tried to double the % on ffmpeg request but it didn't work, all the paths are correct and the input file is not damaged or anything.
The ffmpeg request works fine when I execute it directly from the prompt.
