• Powerpoint can't show a video with headers. I see green screen

  28 novembre 2017, par zinon

  I’ve created a video using ffmpeg that contains headers.

  My script for creating it is :

  ffmpeg.exe -f rawvideo -vcodec rawvideo -s 560x448 -r 40 -pix_fmt yuv420p -i C_L_560x448_40_static_maxSSIM_QP23_B2.yuv -vcodec rawvideo -qscale 0 -filter_complex "drawtext=fontsize=32: fontfile=FreeSerif.ttf: text='SSIM=0.961': x=(w-tw)/2: y=(lh/2): fontcolor=orange, drawtext=fontsize=22: fontfile=FreeSerif.ttf: text='Bitrate≤1800 [1873 kbps], Frame rate≥40 [43.98 fps]': x=(w-tw)/2: y=(lh/2+30): fontcolor=orange : box=1: boxcolor=0x00000099, drawbox=x=80:y=160:w=220:h=135:color=red@0.5" C_L_560x448_40_static_maxSSIM_QP23_B2_new.avi

  Firstly, media player showed it as green screen. I downloaded

  Media Player Codec Pack

  and now show its correclty.

  However, when I insert it in powerpoint 2016 I have the same problem of green screen. Do you know how to fix this ?

  vlc player can play it correctly. Is there any way to change the player of excel and use vlc player instead ?

  I am trying to livestream my Desktop in Ubuntu to Youtube and used this cmd. Youtube livestream showed green bar with "Receiving your data" and Youtube log also showed "Stream healthy", however no video showed up in Youtube player, and after a short while Youtube log said "Stream complete". What’s missing in my cmd ?

  ffmpeg -f x11grab -r 10 -s 1024x720 -i :0.0 -vcodec libx264 -pix_fmt yuv420p -preset ultrafast -g 20 -b:v 2500k -threads 0 -bufsize 512k -f flv rtmp ://a.rtmp.youtube.com/live2/myKey

  BTW, only screencasting doesn’t work for me, streaming a video file works for me.

• ffmpeg - Creates a Terminal like Text Video Instead of Slide Show Of Images

  15 novembre 2017, par RAJESH KUMAR ARUMUGAM

  I am using ffmpeg encoder to render Images in my Android App with the Help of this Library

  The following Command is used to Render video from a list of images.

  String command[] = {"-r","1/5","-i",gpxfile.getAbsolutePath(),"-c:v","libx264","-vf","fps=25","-pix_fmt","yuv420p",root.getAbsolutePath()+"/"+"video.mp4"};

  and here the gpxfile is my text file that contains the following

      file '/storage/emulated/0/DCIM/Camera/P_20170807_143916.jpg'
  
      duration 2
  
      file '/storage/emulated/0/DCIM/Pic/P_20170305_142948.jpg'
  
      duration 5
  
      file '/storage/emulated/0/DCIM/Camera/P_20170305_142939.jpg'
  
      duration 6
  
      file '/storage/emulated/0/DCIM/Pic/P_20170305_142818.jpg'
  
      duration 2

  My Problem is While Running the Command it renders a Terminal Like Black Screen with the TextPaths inside the file instead of a Video...!!!
  Any Suggestions...??

  Here is my Project Source Code
