• FFmpeg: Unable to find a suitable output format for 'mpegts'

  27 April 2021, by Chris

  I am using the following command on several video streams to pipe them into my TVHeadend server.

  


  pipe:///usr/bin/ffmpeg -i *URL* -c copy -metadata service_provider="My Provider" -metadata service_name="My Service"-f mpegts pipe:1


  


  This command works fine for most of the streams, but a few are throwing this error...

  The problem streams do work.
I searched before asking this question and everything I found was related to conversion.
Can anyone see what I am doing wrong?
The reason behind the using FFmpeg and piping is to eliminate issues with stream freezes. FFmpeg just handles hitches etc better than simply adding the URL straight into my TVHeadend server.

  


• FFmpeg no such filter 'tpad'

  29 August 2022, by Zeek Aran

  I have a simple gif. I am not in general familiar with FFmpeg commands so I assume it's just my syntax being wrong, but what I'm using is straight from an answer here so I thought it would work.

  


  I'm trying to add a delay on the last frame of my gif.

  


  ffmpeg -i out.gif -vf tpad=stop_mode=clone:stop_duration=2 out2.gif


  


  But I'm getting this when I try it:

• AccessViolationException occurred in AForge.Video.FFMPEG.dll

  11 May 2017, by Prakash M

  I have a camera class, in this class I used a timer and in its tick event I am saving video using AForge.Net’s VideoFileWriter in C++/Cli (x86, .net framework: v4.6).
  This is not supposed to happen, as this is managed code. But even if I wrap in try catch block, program crashes because of AccessViolationException. I have verified that Image is not null. Something to do with VideoFileWriter. This happens anytime between app start to 30 minutes of running.

  An unhandled exception of type ’System.AccessViolationException’
  occurred in AForge.Video.FFMPEG.dll
  Additional information: Attempted to read or write protected memory.
  This is often an indication that other memory is corrupt.

  In Visual Studio’s output I see

  Exception thrown at 0x0C4D689F (swscale-2.dll) in test.exe: 0xC0000005: Access violation writing location 0x09F83D80.
  Exception thrown: ’System.AccessViolationException’ in
  AForge.Video.FFMPEG.dll

  code:

   private: System::Void Video_Recorder_Tick(System::Object^  sender, System::Timers::ElapsedEventArgs^  e)
  
    {
  
        Bitmap^ save = ConvertMatToBitmap(image); //function to convert opencv's Mat to .net's Bitmap        
  
        if(writer!= nullptr)
  
         writer->WriteVideoFrame(save);
  
         delete save;
  
     }
  
  
  
    VideoFileWriter ^writer = gcnew VideoFileWriter();
  
  
  
    private: Void load_VideoWriter()
  
    {
  
      writer->Open("C:/video.avi", 640, 480, 10, VideoCodec::Default);        
  
    }

  Visual Studio showed few values for writer

  BitRate 400000
  Codec Default
  FrameRate 10
  Height 480
  IsOpen true
  Width 640
  

  Let me know if anybody needs more info.
  call stack didn’t help much

  

  To my surprise no one on internet is having this issue!
  Code seems straight forward, what could possibly be the issue?
