• Add aac single audio to MPEG DASH mpd files

  26 avril 2017, par Adminy

  I am trying to add manually to the .mpd file the following code.

      <adaptationset contenttype="audio" segmentalignment="true" bitstreamswitching="true" lang="English">
  
          <representation mimetype="audio/mp4" codecs="mp4a.40.2" audiosamplingrate="44100">
  
              <audiochannelconfiguration schemeiduri="urn:mpeg:dash:23003:3:audio_channel_configuration:2011" value="2"></audiochannelconfiguration>
  
              <segmenttemplate timescale="44100" media="http://localhost/audio.aac" startnumber="1">
  
              </segmenttemplate>
  
          </representation>
  
      </adaptationset>

  But its not working, Does everything have to be segmented in .mpd files ? or can I have a single .acc file ?

• FFMPEG - Overlay stop updating after few minutes

  27 décembre 2018, par Vincent Carretero

  First im sorry for my english :-(

  I do streaming from RTSP to Facebook live (RTMP).
  I overlay PNG file, on the stream left corner, with score information and time (like tv soccer match).

  After few minutes, the image overlay dont refresh, and i dont know why...
  Image is updated by vbscript, and its correctly done.

  This is my code :

  cmd.exe /K ffmpeg.exe ^
  
  -f lavfi -y ^
  
  -i anullsrc -rtsp_transport tcp ^
  
  -i "rtsp://xxx:xxx@xxx:8080/videoMain" ^
  
  -r 1 -loop 1 -f image2pipe -i 762141_marquage.png ^
  
  -filter_complex "[2:v]setpts=PTS-STARTPTS[a];[1:v][a]overlay=10:10" ^
  
  -tune zerolatency -vcodec libx264 -c:v libx264 -crf 30 -preset ultrafast -c:a aac -strict experimental ^
  
  -f flv "rtmp://xxx"

  Some one can help me ? please :-)

• Generate Multiple Thumbnails from Multiple Videos (with FFmpeg)

  30 juin 2020, par netsonicyxf

  I have multiple videos in different locations, something like :
D :\Folder 1\001.ts
E :\Folder 2\abc.avi
F :\Foder X\视频.mp4 (some videos name are in non-English languages)

  


  And I already have a filelist.txt with these file path in it

  


  


  file 'D :\Folder 1\001.ts'

  


  


  


  file 'E :\Folder 2\abc.avi'

  


  


  


  file 'F :\Foder X\视频.mp4'

  


  


  For each video, I want to generate 3 images, starting from 00:00:10, then next image every 10 sec.
The name of the image should be the name of the video + number staring from 1, something like
001_1.jpg, 001_2.jpg, 001_3.jpg
abc_1.jpg, abc_2.jpg, abc_3.jpg
视频_1.jpg, 视频_2.jpg, 视频_3.jpg

  


  how to do it in Windows 10 ?
