• FFmpeg ignores some HTTP options when using the PUT method

  6 mars 2020, par mehdi.r

  I am using FFmpeg to create a CMAF stream and I upload it to an AWS resource (AWS MediaStore) using the PUT method of FFMpeg.
  I need to pass the Content-Type header when uploading manifests & segments.
  I have 3 type of files :

  application/x-mpegURL : m3u8 manifest

  application/dash+xml : mpd manifest

  video/mp4 : video segments

  Currently, all the types are set to Binary - octet-stream in the AWS resource (AWS MediaStore).
  As I will upload a huge number of files, I can’t use AWS Lambda functions to set the correct content type after a file as been uploaded.

  FFmpeg upload logs

  [https @ 0x555fe7a7d1c0] Opening 'https://XXXX.YYYY.amazonaws.com/chunk-stream0-00001.mp4' for writing
  
  [https @ 0x555fe7a7d0c0] request: PUT /chunk-stream0-00001.mp4 HTTP/1.1
  
  Transfer-Encoding: chunked
  
  User-Agent: Lavf/58.28.100
  
  Accept: */*
  
  Connection: keep-alive
  
  Host: XXXXX.YYYY.amazonaws.com
  
  Icy-MetaData: 1

  My tries

  I tried static builds & master branch of FFMpeg.
  I tried different ways to pass the content type, without success :

  -mime_type 1 -headers "Content-type: video/mp4\r\n"

  -mime_type "video/mp4,application/dash+xml,application/x-mpegURL"

  -content_type application/dash+xml

  -multiple_requests 1  -headers "a:b" -icy 0

  Upload command :

  ./ffmpeg -re -i ~/videos/BigBuckBunny.mp4 -loglevel debug \
  
    -map 0 -map 0 -map 0 -c:a aac -c:v libx264 -tune zerolatency \

   -strict experimental -lhls 1 -remove_at_exit 0 -master_m3u8_publish_rate 3 \
  
   -f dash -method PUT -http_persistent 1  https://example.com/manifest.mpd

  Any help would be highly appreciated.

• Pydub dir error . dynamic file path doesn't play sound but with specific file path the code works fine

  20 avril 2021, par anshul raj

  I don't know what's wrong with this code - it works fine when I provide an exact file path to the music file, but if I pass it in a dynamic way, it doesn't work.

  


  Actually my code is that user give a music file name it get downloaded then with the meta id it find the file in downloads dir then play it

  


   def songplayer(self,meta):
        def playmmusic(name):
            from pydub.playback import play
            from pydub import AudioSegment
            AudioSegment.converter = "C:\\ffmpeg\\bin\\ffmpeg.exe"
            AudioSegment.ffmpeg = "C:\\ffmpeg\\bin\\ffmpeg.exe"
            AudioSegment.ffprobe = "C:\\ffmpeg\\bin\\ffprobe.exe"
            sound = AudioSegment.from_file(name)
            play(sound)

        print(colored("Currently Playing : " + meta['title'],'yellow'))
        r=meta['id']
        tt='./downloads/'+r
        playmmusic(tt)
