• avcodec/wmv2dec : Zero mb_type array for I pictures

  avcodec/wmv2dec : Zero mb_type array for I pictures
  Up until now, ff_wmv2_decode_secondary_picture_header() only
  
  set the mb_type array for non I-pictures, so that the decoding
  
  process uses the earlier values of this array ; this affects
  
  the output of the wmv8-x8intra FATE-test (which this patch
  
  therefore updates). These earlier values were set when decoding
  
  earlier frames or when the buffer was initially zero-allocated.
  
  A consequence of this is that the output of this test would be
  
  random if ff_find_unused_picture() would select the unused picture
  
  to return at random. Furthermore decoding from a keyframe onwards
  
  depends upon the earlier state of the decoder.
  This patch therefore zeroes said array when decoding an I picture.
  (It is not claimed that zero is the right value to fill the array with.
  
  I just don't know.)

• Dailymotion Video Url to Audio Downloader

  27 août 2020, par Maisum Abbas

  I am trying to create Dailymotion Video URL to Audio Downloader. Since I have to deploy it on Firebase, I will have to use JavaScript, hence node.js. I have tried various approaches by following different links but didn't find anything that works for me. Most of them are based on terminal from where they can run which I don't require including ffmpeg. One ffmpeg tutorial I found was based on uploading videos and then converting it to audio which didn't work with the URL. Also, I didn't find any code from where I can use or read to manage ffmpeg in code, just found the guide of how to use it in terminal. So can anyone guide me where I can get a useful link that can help me. I have tried on GitHub as well. Really hoping to get help from here.

  


• wowza multiple files in one playlist

  14 février 2014, par kalafun

  Is it possible to create a stream in wowza from multiple files ? So these file would be played in a row after each other ? As far as I know, I can only stream from one file being in the content directory..

  1.) I would like to split that one file for my own reasons, to add some security to it etc... , and then to create the playlist from these multiple files and publish it for streaming.. so it won't take that much time comparing to the second way.

  2.) Or do I need to put these multiple files back together and then publish the playlist ?

  I would also like to consider the time of the playlist being created even using a big file. I am using ffmpeg to split the file into smaller pieces using a script.

  Therefore it would be automatic, when a user would request a stream, I run the script that splits the files and creates the playlist for user..

  I hope I didn't take it from the wrong way. Help please
