• Failed to find two consecutive MPEG audio frames [closed]

  3 décembre 2024, par matrixebiz

  I'm receiving this error trying to download/convert an m3u8

  


  [mp3 @ 000001c8f5112200] Format mp3 detected only with low score of 1, misdetection possible!
[mp3 @ 000001c8f5112200] Failed to find two consecutive MPEG audio frames.
[in#0 @ 000001c8f5111f40] Error opening input: Invalid data found when processing input


  


  Any way to fix this in my ffmpeg command line ? Also, playing the stream in VLC and other apps shows this in the path /%EF%BB%BF for some reason.
VLC is unable to open the MRL 'file :///C :/Temp/%EF%BB%BF'. Check the log for details. Then it will play the actual video.

  


  Do i need to change the beginning of the m3u8 ?
#EXTM3U
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=1000,RESOLUTION=640x360,

  


  Even if I remove it and just leave the URL that is inside the m3u8, will still display the %EF%BB%BF which I need to stop from happening

  


  EDIT : Adding the PowerShell script I'm using to output my file :

    )
    
    #Escape the regex meta characters, this assumes literals are used in the input
    $File1StartAnchorEscaped = [System.Text.RegularExpressions.Regex]::Escape($File1StartAnchor)
    $File2StartAnchorEscaped = [System.Text.RegularExpressions.Regex]::Escape($File2StartAnchor)

    if ($PSBoundParameters.ContainsKey('File1EndAnchor'))
    {

  I use this command on ffmpeg :

  /usr/local/bin/ffmpeg -ss 40 -t 40 -i mymusic.mp3 -ab 15 voice.mp3 2>&1

  but I see this error :

  Automatic encoder selection failed for output stream #0:0. Default encoder for format mp3 (codec png) is probably disabled. Please choose an encoder manually. Error selecting an encoder for stream 0:0

  Also lamemp3 installed and enabled, how can I fix it ?

• ffmpeg capture raw/orignal stream from timeleak HD 72 with audio

  30 septembre 2013, par Max

  Timeleak card claim that they support Audio.
  I got the second hd75a card. (I had hd82a)

  I can't start capturing audio.

  It captures video :-

  ffmpeg -f dshow -i video="7160 HD Capture" out.mp4

  Here are options :-

  ffmpeg -f dshow -list_options true -i video="7160 HD Capture"

  [dshow @ 000000000253ba60]  Pin "Audio"

  This card should encode MPEG2

  1. Does that capture command write to file original MPEG2 stream from hardware or it is re-encoded ?

  2. How do I get original MPEG2 stream ? (If first command is re-encoding it OR may be there is no way to get original encoded frames at all)

  3. Does "Video Stream" includes audio track ? (Pin "Audio")
     There is no extra audio device and it seems audio stream is in video stream.

  I wish to get raw (not re-encoded, original MPEG2 encoded by hardware) and audio. It is Ok If I will get original not encoded stream without loosing frames.

  Offtopic : If you have such card : Do you have horizontal artifact lines when picture moves ?
