• Uploading video to Twitter sometimes doesn't work

  22 juillet 2021, par K-s S-k

  I have a very difficult situation. I've already spent 2 days and couldn't find a solution. Project on Laravel. I want to upload videos to Twitter using the Twitter API endpoints. But sometimes I am getting this error :

  


  


  file is currently unsupported

  


  


  I did everything as recommended in the official documentation Video specifications and recommendations. I get an error when I set an audio codec is aac in my video file, despite the fact that it is recommended in the official documentation, but when I set the audio codec to mp3, the video is uploaded, but the sound quality is very poor, and sometimes there is no sound at all. Please forgive me if this is awkward to read, but I want to provide all of my code. Because I don't know how to solve this anymore and I think it might help.

  But if i exceute this command through CMD then my video file is created successfully.
  i want to know whats the problem behind it,i am searching from 2 days on it,but could not get the solution,i thing its problem of Execute Permission In android.Plzzz help me,,,or tell me is it possible to in android to make a video file using FFMPEG.

• FFmpeg Idet with Timecode/Frame Number ?

  13 avril 2021, par Matt Cohen

  Is it possible to get ffmpeg to tell you which frames it thinks are interlaced/progressive when running the idet filter ?

  


  My use case is that when interlaced frames are detected in a file I need to be able to know which frames ffmpeg thinks are interlaced so I can easily pull them up and check if ffmpeg was correct in its assessment. Sometimes aliasing and thin lines in animation throw it off.
