• ffmpeg - How to determine if -movflags faststart is enabled ? PHP

  20 août, par IIIOXIII

  While I am able to encode an mp4 file which I can play on my local windows machine, I am having trouble encoding files to mp4 which are readable when streaming by safari, etc.

  



  After a bit of reading, I believe my issue is that I must move the metadata from the end of the file to the beginning in order for the converted mp4 files to be streamable.

  



  To that end, I am trying to find out if the build of ffmpeg that I am currently using is able to use the -movflags faststart option through php - as my current outputted mp4 files are not working when streamed online.

  



  This is the way I am now echoing the -help, -formats, -codecs, but I am not seeing anything about -movflags faststart in any of the lists :

  



  exec($ffmpegPath." -help", $codecArr);
for($ii=0;$iibr>';
}


  



  Is there a similar method of determining if -movflags fastart is available to my ffmpeg build ? Any other way ? Should it be listed with any of the previously suggested commands ? -help/-formats ?

  



  Can someone that knows it is enabled in their version of ffmpeg check to see if it is listed under -help or -formats, etc.?

  



  TIA.

• ffmpeg avformat_open_input with custom stream object

  26 avril 2017, par trigger_death

  I’m currently trying to write a custom SoundFileReader for SFML using ffmpeg’s libraries. The only thing I have available to use with avcodec and avformat is the class InputStream below which is part of SFML. I’ve looked at avformat_open_input and AVIOContext and I learned how to use custom stream with a buffer but how do I create an AVIOContext that works with the custom read, seek, and lseek functions ?

  class InputStream {
  
      int64_t getSize()
  
      int64_t read(void* data, int64_t size);
  
      int64_t seek(int64_t position);
  
      int64_t tell(); // Gets the stream position
  
  };

• Cannot download and install ffmpeg for python

  19 février 2017, par ismail yussuf

  I’m having a problem with downloading ffmpeg for python. It seems to me that no matter what I do it just doesn’t work.
  Btw ,sorry for the images but I still don’t know how to post my command prompt on here. So here is the error i’m getting.

  

  I’ve already tried "pip install ffmpeg-normalize" and when I do that I get this.

  

  FYI I already downloaded imageio and that went totally fine. I even have the ffmpeg.py file in imageio. Does anyone know how I can install it properly ?
