• HLS Encoding Resulting in "No Supported Source Was Found"

  18 février 2023, par Paulamonopoly

  I'm currently facing the most bizare problems I've come across, so I'm hoping someone can explain why this is happening. I'm currently converting my Movie and Show libary to HLS for buffering and bandwidth reasons etc.

  


  My file structure for these movies and shows are as follows :

  


  /Movies/[TMDB ID]/[TMDB ID].mp4

  


  /Shows/[TMDB ID/[Season Number]/[Episode Number]/[Episode Number].mp4

  


  I have converted my entire movie collection successfully using the below command.

  


  find /* -type f -name "*.mp4" -exec realpath {} \; -exec ffmpeg -i {} -codec: copy -start_number 0 -hls_time 10 -hls_list_size 0 -f hls -hls_segment_filename '{}-P%03d' {}.m3u8 \;


  


  This is taking my named mp4 files and converting them to the originalname.m3u8 with chunks following the naming scheme of originalname-PXXX where P indicates the part number. I know there's no file extensions attached with the chunks but it's not needed.

  


  You can view this result here : Example

  


  This result also works if loaded into HLS Player : HLS Player

  


  So there is evidently nothing wrong with the converting of my videos or even the result of the videos.

  


  Now, if I convert a TV Show using the exact same command, it does indeed convert them, it does use a slightly different file structure as with seasons and episodes etc which can be seen above, but now it results in the error : "No Supported Source Was Found" in the console and repeatedly tries to play Part 000 without success.

  


  This can be seen here : Example

  


  And the errors if loaded into HLS Player : HLS Player

  


  I have tried changing numerous things to try and resolve this error as well as checking things, the things I have checked are the media condition itself maybe it's a corrupted file ?

  


  The original Mp4 file can be played here without any problems, so we know the Mp4 file originally is perfectly fine. I have also tried adding a file extension to the chunks such as .ts and .mp4 etc etc with also no success.

  


  I have even thought maybe it's the directories so I have moved a show into the movies directory with no success, I have also moved a movie into the show directory which resulted in a working HLS Stream so it's nothing to do with the directories.

  


  I have tried exending the file name length thinking it's possibly the naming scheme with 1.m3u8 not been long enough of a file name by using placeholder text such as 03051.m3u8 as well as the chunk naming scheme 03051-PXXX possibly not been long enough.

  


  I have noticed though that using this command :

  


  ffmpeg -allowed_extensions ALL -i {} -c copy -bsf:a aac_adtstoasc {}.mkv \;


  


  Does recombine my HLS video correctly with the same file size etc, however I have noticed that the video itself is corrupt and doesn't play. So this makes be believe the issue lies within the converting of the initial Mp4 file into m3u8.

  


• how do go through multiple folders using mmpeg to generate multiple videos ?

  15 février 2023, par Megan Darcy

  I have this piece of code that works as expected for me, but it only converts the images in a single folder into a single video.

  


  If I have multiple folders, and they may be recursive, how do I do that ?

  


  The file structure could be either something like this but the names are different :

  


  VideoFolder1
  
|
  
|— SubFolderA

  


  


  SubsubFolder2 (contains images with similar names but different numbers e.g Tobias.023.png, Tobias.024.png, Tobias.025.png)

  


  


  |
|— SubFolderB

  


  


  SubsubFolder3 (contains images with similar names but different numbers e.g Joey.027.png, Joey.028.png, Joey.029.png)

  


  


  This is my current code :

  


  import os
os.system("ffmpeg -f image2 -r 30 -i ./Front/4ZJSI_Colored_Li_F.%04d.png -vcodec mpeg4 -y ./videos/4ZJSI_Colored_Li_Front.mp4")
    
    


  


  How do I convert the contents of Subsubfolder2 and subsubfolder3 and subFolderA etc to multiple videos of the same name as per the content of each folder and subfolder ? .

  


  Thanks !

  


• Run scripts in other instances and pass variables from the first script to the second

  3 février 2023, par Tyrone Hirt

  I have the following script :

  


  Get-ChildItem -Path $RenderClient -Recurse -Filter "ffmpeg crop.ps1" |
  Where-Object { Test-Path (Join-Path $_.DirectoryName *.mp4) } |
  ForEach-Object {
  try {
  Start-Process -WorkingDirectory $_.DirectoryName powershell.exe "-NoExit -File `"$($_.FullName)`""
  }
  catch {
  Write-Host -NoNewline -ForegroundColor Red "Não foi possivel cortar o arquivo:"; Write-Host -NoNewline -ForegroundColor White " $_.Name "; Write-Host -NoNewline -ForegroundColor White "`nMensagem de erro:"; Write-Host -NoNewline -ForegroundColor Red " $($_.Exception.Message)`n";
   }
  }
 }


  


  This code is a part of my first script, basically it looks for ffmpeg crop.ps1 files that have a .mp4 file in the same folder and runs those scripts.

  


  The issue is that I would like to make the process a little cleaner and more practical, currently when I need to make a change in the ffmpeg crop script I need to open all the folders and change one by one.

  


  To avoid this, I would like to have a single file ffmpeg crop.ps1, and every time a .mp4 file is found in the path specified in the first script, an instance of that single script ffmpeg crop.ps1 is triggered, too I need $_.FullName and $_.Name of each .mp4 file found to be passed to each respective instance so that I can use these values ​​within the ffmpeg crop script.

  


  I've been racking my brain for days trying to get this to work, I'll be very grateful for any help with this.

  


  Edit - in more detail

  


  The $RenderClient folder of my script is C:/Videos inside that folder there are several child folders that follow the logic : 01-01, 01-02,02-01, 02-02...

  


  

  


  Currently, inside each child folder there is a script ffmpeg crop.ps1, this script is responsible for cutting a piece of the video that is inside that folder, however it is only activated if there is a .mp4 file to be cut, in the same folder that it, that is, for the script ffmpeg crop.ps1 to be activated in folder 01-01, it is necessary to have the script itself and a .mp4 file.

  


  This script would be triggered

  


  

  


  This script would not be triggered

  


  

  


  The point is, I would like to make this more practical, so instead of having one ffmpeg crop.ps1 script inside each child folder, I would like to have only one ffmpeg crop.ps1 script, and it would stay in the parent folder.

  


  I would like it to work like this :

  


  

  


  For that, I would need to change my code, so that the script recursively searches for .mp4 files inside the parent folder, for each file that is found, it must open an instance of the script ffmpeg crop.ps1 that is in the parent folder and pass the variables $_.Name and $_.FullName of the files found to the respective instance of the open ffmpeg crop.ps1 script, so that each instance will be executed correctly.
