  20 avril 2017, par inpost

  Reallive video streaming in twitch and gaming.youtube are using new technologies HTML5 : blob:url . What name is this blob format ?

  And second question : i use nginx-rtmp server on my site, translate from clients is using flash (on site), OBS or xsplit. On server i convert to FLV and HLS formats with ffmpeg. I want to learn how to make streaming with new technologies without flash. How to realize convert video from flv to BLOB format ? Is it possible to add extra query to ffmpeg ?

  Very-very BIG thank you. :)

• Use mmpeg to encode AUDIO+IMAGE into a VIDEO for YouTube

  12 juin 2014, par pablosz

  I need to generate a video containing a single image throughout the duration of the audio comming from an audio file. This video should be compatible with the parameters supported by YouTube.

  I’m using ffmpeg.

  I was trying various configurations explained right here and in other forums but not all have worked well.

  I’m currently using these settings :

  ffmpeg -i a.mp3 -loop 1 -i a.jpg -vcodec libx264 -preset slow -crf 20 -threads 0 -acodec copy -shortest a.mkv

  Where a.mp3 containing audio, a.jpg contains the image and a.mkv is the name of the resulting video.

  Using these parameters a.mkv works well on YouTube and can be played with Media Player Classic ; but KMPlayer only recognizes the audio, showing a blank image as background.

  My questions are two :
  1 - There is something wrong that causes KMPlayer to fail ?
  2 - Is there any configuration that can deliver the video faster, of course losing some compression ?

  Muchas gracias !

• using FFmpeg converter from .mov format from portrait to landscape mode

  30 juin 2014, par Sohail Yasmin

  I have a critical problem. I am sharing the details with you.

  Problem : - I have a video file in .mov format, taken from the IPhone. This video is in portrait mode, I want to play this video on the webpage in landscape mode and vice versa.

  Please suggest me, should I convert my video from portrait to landscape mode using FFMPEG. Does FFMPEG provide this conversion feature ? If yes, Please send the exe and the command line for converting portrait video into landscape mode and vice versa.
  i am using these commands

  ffmpeg -i "Inputname.mov" -acodec libvorbis -ac 2 -ab 96k -ar 44100 -b 345k output.webm
  
  ffmpeg -i "Inputname.mov" -b 1500k -vcodec libx264 -vpre slow -vpre baseline -g 30 output.mp4
  
  
  
  ffmpeg -i "Inputname.mov" -b 1500k -vcodec libtheora -acodec libvorbis -ab 160000 -g 30 output.ogv
