  vaapi_h265 : Fix slice header writing
  This was not observed earlier because the only syntax element which
  
  it normally misses with the current setup is slice_qp_delta, but that
  
  is always going to be zero (in IDR frames QP isn’t varied on the
  
  slice) which will always exp-golomb code as a single 1 bit.  The
  
  immediately following part is the byte alignment, which is always a 1
  
  bit followed by 0s which are ignored, so as long as the bitstream is
  
  never aligned at that point we will never notice because the only
  
  difference is that an ignored bit is a 1 instead of a 0.

• How to display 4 rtsp on one screen using Raspberry PI ? [closed]

  19 avril 2023, par Stoufiler

  I've been trying to display 4 rtsp streams simultaneously on a single screen.

  


  I installed go2rtc on which I configured 4 streams.
Each of them works correctly whether it is by Web or by VLC.

  


  However I want to have a 2X2 display that will run on a Raspberry PI 3.

  


  When I start the script :

  


  ffmpeg -rtsp_transport tcp \
    -i rtsp://admin:pass@192.168.0.200:8554/mamie \
    -i rtsp://admin:pass@192.168.0.200:8554/SALON \
    -i rtsp://admin:pass@192.168.0.200:8554/SALON2 \
    -i rtsp://admin:pass@192.168.0.200:8554/SALON3 \
    -filter_complex "
        nullsrc=size=1920x1080 [base];
        [0:v] setpts=PTS-STARTPTS, scale=960×540 [upperleft];
        [1:v] setpts=PTS-STARTPTS, scale=960×540 [upperright];
        [2:v] setpts=PTS-STARTPTS, scale=960×540 [lowerleft];
        [3:v] setpts=PTS-STARTPTS, scale=960×540 [lowerright];
        [base][upperleft] overlay=shortest=1 [tmp1];
        [tmp1][upperright] overlay=shortest=1:x=960 [tmp2];
        [tmp2][lowerleft] overlay=shortest=1:y=540 [tmp3];
        [tmp3][lowerright] overlay=shortest=1:x=960:y=540
    " \
    -c:v libx264 \
    -preset superfast -crf 18 -f matroska – | ffplay –


  


  ...nothing is displayed and I have a lot of errors :

  Can someone help me ?

  


• Raspberry Pi > CRTMPServer > JWplayer

  18 juin 2015, par user3147697

  I’m trying to get a raspberry pi to stream to a crtmpserver, and from there to a webpage with JWplayer.

  I am able to send video successfully to crtmpserver with this :

  raspivid -t 0 -w 960 -h 540 -fps 25 -b 500000 -vf -o - | ffmpeg -i - -acodec aac -ac 2 -strict experimental -ab 160k -vcodec libx264 -preset slow -profile:v baseline -level 30 -maxrate 10000000 -bufsize 10000000 -b 1000k -f rtsp -metadata title=teststream rtsp ://192.168.1.20:5544/flvplayback

  But am having trouble viewing the stream from crtmpserver using this is my html jwplayer code :

  <code class="echappe-js">&lt;script type=&quot;text/javascript&quot;&gt;<br />
  
      jwplayer(&quot;myElement-teststream&quot;).setup({<br />
  
          playlist: [{<br />
  
              sources:[{<br />
  
                  file: 'rmtp://192.168.1.20:1935/live/teststream&quot;<br />
  
              }]<br />
  
          }],<br />
  
          height: 1080,<br />
  
          primary: 'flash',<br />
  
          width: 1920<br />
  
      });<br />
  
      &lt;/script&gt;
  
  

  What am I missing ?
