• Converting Video files in a Azure Webjob with ffMpeg

  13 décembre 2016, par Kevin Phifer

  I’m having trouble using ffMpeg in an Azure webjob.

  I found the following article (How to call ffmpeg.exe to convert audio files on Windows Azure ?) and it is exactly what I want to do, however, I cannot get ffMpeg to execute and it gives no error message.

  To diagnose the problem, I have boiled it down to its essentials by uploading ffMpeg, a video file to convert, and batch file to run it :

  

  The script in run.cmd is simply :

  del output.mp4
  
  ffmpeg -i screencast.wmv -c:v libx264 -r 15 output.mp4

  This works on my personal machine, but ran as a webjob I get results below.

  Edit :
  Additionally, it was suggested that I run using Kudu console. Still no luck :
  

  Solution :
  I ended up needing to run the 32 version of ffMpeg and not the 64 bit. Thanks so much @mathewc !

• Noobs approach to automate x264 cmd

  16 novembre 2012, par nightcrawler

  so here is my script to loop through specific video extensions » add a manual profile » generate necessary *.bat & finally a final 'loader' batch file to execute previous *.bat files sequentially & necessary logging (this gives quiet a deal of freedom if you so want)

  ::==
  
  :: gets lines into vars c1 v2 v...
  
  @echo off
  
  :: user input required
  
  cd /d "d:\Trainers\out\"
  
  setLocal EnableDelayedExpansion
  
  dir /B /O:N | findstr ".wmv$ " >filename.txt
  
  echo. >log.txt
  
  :: user input required
  
  for /f "tokens=* delims= " %%a in ('type filename.txt ^|findstr ".wmv$"') do (
  
  set /a n+=1
  
  echo. >file!n!.bat
  
  set in=%in%%%a
  
  :: user input required
  
  set out=!in:.wmv=.mp4!
  
  :: user input required
  
  set v=x264 --crf 23  --level 3.1 --tune film -o "d:\Trainers\out\!in!" "d:\Trainers\out\!out!"
  
  echo. !v!>file!n!.bat
  
  )
  
  dir /B /O:N | findstr ".bat$ " >x264_home.txt
  
  for /f "tokens=* delims= " %%a in (x264_home.txt) do (
  
  set /a n+=1
  
  :: mtee is an external library Google it
  
  set "z=call %%a | mtee /d/c/t/+ log.txt"
  
  echo. !z! >> x264_home.bat
  
  )
  
  echo. @echo off > newFile.bat
  
  type x264_home.bat >> newFile.bat
  
  type newFile.bat > x264_home.bat
  
  del newFile.bat,x264_home.txt,filename.txt
  
  echo. pause >> x264_home.bat
  
  echo. @echo All Operation done... >> x264_home.bat
  
  :: user input required
  
  move "d:\Trainers\out\*.bat" "d:\Program Files\x264_auto\test\"
  
  :: user input required
  
  move "d:\Trainers\out\log.txt" "d:\Program Files\x264_auto\test\"
  
  ::==

  Now the above code which is fairly easy to understand (bcz its written by a noob) run perfectly & create necessary files. For instance one of the file1.bat looks like this :

  x264 --crf 23  --level 3.1 --tune film --preset veryslow --deblock -2:-1 --zones 24233,25324,q=20 --acodec aac --abitrate 80 -o "d:\Trainers\out\1.wmv" "d:\Trainers\out\1.mp4"

  ...& the loader .bat file looks like

   @echo off 
  
   call file1.bat | mtee /d/c/t/+ log.txt 
  
   call file2.bat | mtee /d/c/t/+ log.txt
  
   call file3.bat | mtee /d/c/t/+ log.txt
  
   @echo All Operation done... 

  You see this is a quiet flexible approach in that you can use special filestr » set another loop » set another profile. Furthermore every batch file can be latter edited especiialy when you heavily use --zone x264 feature
  I am successful because there is no error in any output ...but its the x264.exe (provider/compiler x264GUI) throws error which it otherwise don't ?

  d:\Program Files\x264_auto\test>x264 --crf 23  --level 3.1 --tune film --preset
  
  veryslow --deblock -2:-1 --zones 24233,25324,q=20 --acodec aac --abitrate 80 -o
  
  "d:\Trainers\out\1.wmv" "d:\Trainers\out\1.mp4"
  
  ffms [error]: could not create index
  
  lavf [error]: could not open input file
  
  raw [error]: raw input requires a resolution.
  
  x264 [error]: could not open input file `d:\Trainers\out\1.mp4' via any method!

  its the x264 thats the culprit perhaps a senior guide is required here

• HLS "bufferStalledError" / "bufferNudgeOnStall"

  20 avril 2022, par Yago

  I'm trying to stream videos with HLS.js, and it works perfectly fine, but when I separate the audio from the video to support multiple audio tracks, it returns these two errors at random times in the video ("bufferStalledError" and "bufferNudgeOnStall").

  


  I've tried using pure ffmpeg, I've tried using shaka packager, and I'm currently using bento4, but this error always occurs

  


  (my bento4 code)
