• FFMPEG restream m3u8 to Youtube keeps returning "Failed to update header with correct duration & filesize" after 1st segment

  12 septembre 2020, par user3263433

  I'm trying to retream a m3u8 live feed toYouTube but I keep running into errors.

  


  When watching the feed in a webplayer it works fine.

  


  The headers of the m3u8 file are as follow :

  


  #EXTM3U
#EXT-X-VERSION:6
#EXT-X-TARGETDURATION:8
#EXT-X-MEDIA-SEQUENCE:127629
#EXT-X-DISCONTINUITY-SEQUENCE:0
#EXT-X-PROGRAM-DATE-TIME:2020-09-12T12:57:13.280Z


  


  Here is the ffmpeg log :

  


  frame=  226 fps= 25 q=29.0 size=    1303kB time=00:00:07.04 bitrate=1516.2kbits/frame=  238 fps=

  It seems like it loads 1 .ts file fine but fails after that.

  


  I'm currently using :

  


  ffmpeg -re -i (urlToM3U8) -codec copy -f flv rtmp://a.rtmp.youtube.com/live2/(streamkey)


  


• Concatenating on Windows throws "Invalid data found when processing input" while it works on Mac and Linux

  15 février 2020, par miguelmorin

  I need to run a command with a nightly build of FFMPEG to report a bug on the concat protocol. I found it difficult to compile from source with libx264 support on Linux, and I want to spare my Mac computer, so I use the nightly build on Windows from Zeranoe.

  I call this command to concatenate the files :

  ffmpeg -safe 0 concat -i files_to_combine -vcodec libx264 show.mp4

  where files_to_combine is :

  file ./short_DSC_0013.MOV
  
  file ./short_DSC_0014.MOV
  
  file ./short_DSC_0015.MOV
  
  file ./short_DSC_0016.MOV
  
  file ./short_DSC_0017.MOV
  
  file ./short_DSC_0018.MOV
  
  file ./short_DSC_0019.MOV

  I call this command from the directory containing the video files and files_to_combine.

  On Windows with a nightly build, I get the error :

  files_to_combine : Invalid data found when processing input
  

  I changed file ./DSC_0013.MOV to these options, all with the same error :

  file 'short_DSC_0013.MOV'
  
  file '.\short_DSC_0013.MOV'
  
  file 'F:\short_DSC_0013.MOV'

  How can I debug this error, or what is the syntax for concatenating on Windows with a nightly build ?

  Update with log-level 48

  I ran the same command with -v 48 and got :

  F :\brain squids>C :\Users\migue\Desktop\ffmpeg-20200211-f15007a-win64-static\bin\ffmpeg.exe -v 48 -i files_to_combine -vcodec libx264 show.mp4

  Update because of wrong command

  I had mistyped the command. The right command has a -f in front of concat, which I found because the accepted answer was able to make the command work in a similar environment :

  ffmpeg -safe 0 -f concat -i files_to_combine -vcodec libx264 show.mp4

• ffmpeg only processes first image

  8 septembre 2020, par Michael Price

  I have a directory of .png images (I had previously tried .jpg until I read somewhere ffmpeg prefers .png).

  


  The images share a file numbering format cof000.png - cof358.png.

  


  I want to convert those images into a moving picture format. MPG or MP4 will be fine.

  


  The command I have tried is

  


  ffmpeg.exe -framerate 25 -i cof%03d.png -r 6 output.mp4


  


  I adapted the command from this post, here :

  


  https://stackoverflow.com/questions/53778503/ffmpeg-video-slideshow-only-takes-first-image


  


  Even after trying numerous different permutations of the command the final file only has the first image in it. I am using windows.

  


  What ffmpeg command do I need to use on Windows to compile all 180 image files into a single moving image ?

  


  Here is the output from using the command :

  


  $ ffmpeg.exe -framerate 25 -i cof%03d.png -r 6 output.mp4
