• CVAT error during installation of development version

  28 novembre 2022, par Raman

  I'm trying to install development version of CVAT according to official instruction but struggling at the step of requirements.txt applying :

  


  pip install -r cvat/requirements/development.txt


  


  ... with following error :

  I have already tried suggested fixes, but no luck :
https://github.com/openvinotoolkit/cvat/issues/4406

  


  Environment :

  


  

  • MacBook Pro (Intel x64)

  


  • macOS Monterey (Version 12.4)

  


  • (pyenv) Python 3.9.10

  


  


  What other options could be applied to fix it ?

  


• FFmpeg converting to .265 corrupts videos

  25 juin 2022, par Alfa

  I'm trying to convert and compress videos in React Native using FFmpegKit, what is strange is it is very slow regardless of the preset I use, Also, no matter how big the input video is, it always produces a video less than 1MB that is corrupt.
This is my first time using FFmpeg, I'm using it due to the lack of good video compressing libraries on React Native.

  


  My command looks like this :

  


  const getFFmpegCommand = (input: string, output: string) => {
  const scale = `"scale='if(gte(iw,ih),min(720,iw),-2):if(lt(iw,ih),min(720,ih),-2)'"`;
  const preset = '-preset veryfast ';
  const ffmpegCommand = `-i ${input} -y -crf 28 -vf ${scale} ${preset} -c:v libx265 ${output}`;
  return ffmpegCommand;
};


  


  This is my log output

  its weird since all the other code in my bot works fine like the !info command, so it must be an error with either youtube-dl or ffmpeg. But then again it doesnt join the voice call in the first place so that might be the error. i added ffmpeg to path but i still wrote the path to it here player = discord.FFmpegPCMAudio(song, **ffmpeg_options, executable="C:\\Users\\jonas\\Documents\\ffmpeg-2022-06-16-git-5242ede48d-full_build\\ffmpeg-2022-06-16-git-5242ede48d-full_build\\bin\\ffmpeg.exe"). i followed this tutorial for the bot https://www.youtube.com/watch?v=Q8wxin72h50&t=1040s i did everything he did but it didnt work. My discord.py version is 2.0.0 my Python version is 3.10.5 and my youtube_dl version is 2021.12.17 my ffmpeg download is ffmpeg-2022-06-16-git-5242ede48d-full_build. I tested it on discord.py 1.73 and it worked fine. This was in intellij though whilst my main program is in Visual Studio Code but i couldnt see it making any big difference so it could be the intents that makes the program not work.I couldnt see any mistakes in the code but im new to discord.py, youtube_dl and ffmpeg stuff so unless visual studio code showed me what i did wrong, i wouldnt notice. But what did i do wrong and how can i fix it ?
