• FFmpegAudio object has no attribute _process

  28 janvier 2023, par Benjamin Tsoumagas

  I'm trying to make a Discord music bot that is remotely hosted and to do that I need ffmpeg to work. I was able to add it using my Dockerfile but upon trying to play music with the bot I get the following errors. For context, I am hosting on Fly.io and using python with the Nextcord library. Below is my relevant code and the error message. Please let me know if any more information is required.

  Similar posts have been made but their issues were typos in changing 'option' : '-vn' to 'options' : '-vn'. I've combed through for any other errors but I can't find any. I was hoping to see I made a similar mistake, but this is the template I was following from the Nextcord developers and I had no luck :

  


• FFMPEG m3u8 video download from login required site

  30 octobre 2024, par Nirob Saju

  I am trying to download an m3u8 video using FFmpeg from a site that requires login to access the content. When inspecting the Network tab in Chrome DevTools, I see that the response for the /k/timestamp file is encrypted. I have identified some JavaScript files that seem to handle the decryption, and I need help extracting or decoding the AES key used for this encryption.

• Adding Text to Video with ffmpeg in Flutter

  9 mars 2024, par Aiman

  I am trying to add text to a video using ffmpeg package but it returns an error i.e. Return Code 1
Here's my code.

  


    final videoPath = _controller.file.path;
  final outputName = videoPath.hashCode.toString();

  final output =
        File('${(await getTemporaryDirectory()).path}/$outputName.mp4');

  String command =
        "-y -i $videoPath -filter_complex '[0]scale=540:-1[s];[s]drawtext=fontfile=/storage/emulated/0/Download/SuperDessert.ttf:text='MY_TEXT':fontsize=24:fontcolor=white:x=(w-text_w)/2:y=(h-text_h)/2' ${output.path}";

  final session = await FFmpegKit.execute(command);

  final returnCode = await session.getReturnCode();

  if (ReturnCode.isSuccess(returnCode)) {
    log("Success full text added");
  } else {
    log("Error adding text: ${await session.getFailStackTrace()}");
  }


  


  I have tried changing the output directory, changed fontfile to font
