• ffmpeg takes screenshots all at once

  19 décembre 2020, par oo92

  I am trying to use ffmpeg to grab screenshots of twitch streams. This is my command :

  


  ffmpeg -i https://stream-link.m3u8 
-ss 30 
-frames:v 10 
-r 1
-f 
image2 
/home/me/Desktop/images/image-dataset/my-dataset/World-of-Warcraft/filename.jpg&


  


  My goal is to take 1 screenshot per second for a total of 10 screenshots. I've added the & at the end of the filename.jpg to take these screenshots concurrently. However, the screenshots I get are all the same thing. No difference. The exact spitting moment in all 10 images. My take is that ffmpeg is not listening to -frames:v 10 and instead takes 10 screenshots all at once.

  


  I tried to run it sequentially and the same problem happened. So the issue isn't concurrency..

  


  Is there a way I can fix this ?

  


  Output :

• Why can’t VLC go in to fullscreen mode ?

  31 mai 2017, par matiastofteby

  I’m working on a Matlab application that uses a VLC class to control a VLC-instance. One of the features is to set the VLC player to fullscreen. This feature works perfectly fine.

  The VLC player is downloaded from Matlab’s File Exchange : https://se.mathworks.com/matlabcentral/fileexchange/56215-vlc (Thanks a lot Léa Strobino)

  However, one particular clip insists on resizing the player to a smaller size.
  I have done some research and it turns out that this is a common problem in some VLC versions.

  Normal workarounds are to uncheck the “adapt interface to video size” (something like that) and to check the “Fullscreen” box.
  This ought to make the player open in fullscreen and not resize the screen to video size. The video still resizes the player to a smaller size.

  All the specs of the clips are the same : Same file extension (.vob), formats and were made the same way (I did some video trimming and such using ffmpeg – but the same way every time).

  I have noticed one difference and that is that this particular video has a lower Data and bitrate ( 1000-1500kbps) where as the others are higher (<4000kbps). Also when showing the properties of the clip the frame height and width are blank as opposed to the others that have specific values.

  This should however not have an effect of the fullscreen command from Matlab called after loading the video into the playlist. The command has no effect on this video, but does on all other.

  It is possible to set the player to fullscreen manually by clicking the window, so it is not caused by some restriction in the video not allowing it to fullscreen.

  Why does the video refuse to go in to fullscreen ?

  Hope somebody is able to help.

• Low Latency DASH Nginx RTMP

  10 mai 2017, par Kenan Christian

  I use arut nginx-rtmp-module (https://github.com/arut/nginx-rtmp-module) on the media server, then I tried to stream using FFmpeg to the dash application, then I test the stream by playing it using VLC.

  And it waits around 30secs to start playing, and it plays from the beginning, not the current timestamp.

  This is my current config on the RTMP block

  rtmp {
  
      server {
  
          listen 1935;
  
  
  
          application live {
  
              live on;
  
  
  
             exec ffmpeg -re -i rtmp://localhost:1935/live/$name
  
                -c:a libfdk_aac -b:a 32k  -c:v libx264 -b:v 128K -f flv rtmp://localhost:1935/hls/$name_low
  
                -c:a libfdk_aac -b:a 64k  -c:v libx264 -b:v 256k -f flv rtmp://localhost:1935/hls/$name_mid
  
                -c:a libfdk_aac -b:a 128k -c:v libx264 -b:v 512K -f flv rtmp://localhost:1935/hls/$name_hi
  
                -c:a libfdk_aac -b:a 128k -c:v libx264 -b:v 512K -f flv rtmp://localhost:1935/dash/$name_dash;
  
          }
  
  
  
          application hls {
  
               live on;
  
  
  
               hls on;
  
               hls_path /tmp/hls;
  
               hls_nested on;
  
  
  
               hls_variant _low BANDWIDTH=160000;
  
               hls_variant _mid BANDWIDTH=320000;
  
               hls_variant _hi  BANDWIDTH=640000;
  
          }
  
  
  
          application dash {
  
              live on;
  
  
  
              dash on;
  
              dash_path /tmp/dash;
  
              dash_nested on;
  
          }
  
      }
  
  }

  This is the command I use for streaming

  ffmpeg -re -i 2014\ SPRING.mp4 -c copy -f flv 
  
  rtmp://52.221.221.163:1935/dash/spring

  How can I reduce the delay, and make it play from the same timestamp as the streamer ?

  Can I achieve under 5s latency ?

  UPDATE

  Tried to change the playlist length and fragment length, using this directive

  dash_playlist_length 10s;
  
  dash_fragment 2s;

  But still got some latency problem, sometimes it’s smaller than before, sometimes it’s the same
