• Error : Output format mp4 is not available

  12 avril 2024, par alpaca pwaa

  I'm using fluent-ffmpeg in my nextjs application, I'm trying to process the video and specified a format to stream on my s3 bucket but it keeps on failing. My terminal keeps on throwing "Error : Error : Output format mp4 is not available". I already verify my ffmpeg format "ffmpeg -format" and confirm that it supports encoding and decoding mp4 files. I've already tried solutions from other forums but it's not working for me.

• avformat/rtsp : Send mode=record instead of mode=receive in Transport header

  15 janvier 2024, par Paul Orlyk

  avformat/rtsp : Send mode=record instead of mode=receive in Transport header
  Fixes server compatibility issues with rtspclientsink GStreamer plugin.
  >From specification :
  
  RFC 7826 "Real-Time Streaming Protocol Version 2.0" (https://datatracker.ietf.org/doc/html/rfc7826), section 18.54 :
  
     mode : The mode parameter indicates the methods to be supported for
  
           this session.  The currently defined valid value is "PLAY".  If
  
           not provided, the default is "PLAY".  The "RECORD" value was
  
           defined in RFC 2326 ; in this specification, it is unspecified
  
           but reserved.  RECORD and other values may be specified in the
  
           future.
  
  RFC 2326 "Real Time Streaming Protocol (RTSP)" (https://datatracker.ietf.org/doc/html/rfc2326), section 12.39 :
  
     mode :
  
            The mode parameter indicates the methods to be supported for
  
            this session. Valid values are PLAY and RECORD. If not
  
            provided, the default is PLAY.
  mode=receive was always like this, from the initial commit 'a8ad6ffa rtsp : Add listen mode'.
  For comparison, Wowza was used to push RTSP stream to. Both GStreamer and FFmpeg had no issues.
  
  Here is the capture of Wowza responding to SETUP request :

• ffmpeg mp4 to mp3 conversion generates 1 second audio files only [closed]

  24 janvier 2024, par doesnotcompile

  I am having the following problem : I am having trouble converting an mp4 to an mp3.

  


  I have mp4 audio recordings that I need to convert in to mp3 audio files. The mp4 files have been recorded on iOS.

  


  I am currently doing this by using ffmpeg in python like so :

  


  subprocess.run(
            [
                "ffmpeg",
                "-loglevel", "error",
                "-i", ,
                "-q:a", "0",
                "-map", "a",
                
            ]
        )


  


  This runs with no error outputs.

  


  However, the resulting mp3 is only 1 second long, even though the input mp4 is around 5 seconds long.

  


  The mp4 is playable in Quicktime and Apple Music.

  


  ffprobe output :

  


  > ffprobe -v error -show_format input.mp4
[FORMAT]
filename=input.mp4
nb_streams=1
nb_programs=0

TAG:creation_time=2024-01-24T12:47:24.000000Z
[/FORMAT]


  


  No errors shown, and clearly 5 seconds long audio.

  


  Has anyone else experienced similar issues before ?

  


  Happy about any pointers !
