• 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 :

• Suggest an Android FFMPEG Media Player App Supporting SRT Protocol for Video Streaming [closed]

  12 décembre 2023, par ChanduGudimetla

  I am currently in search of an Android application that can serve as a receiver or media player utilizing FFMPEG over the SRT (Secure Reliable Transport) protocol. My primary goal is to receive a video stream from one device (Device A) and mirror the screen onto another device (Device B).

  


  Source Application : I am using StreamPack APK on Device A, which handles the encoding of data effectively. Requirement : I need a receiver application for Device B that can decode this stream.

  


  The key requirements are : It should leverage FFMPEG for decoding. It must support the SRT protocol to ensure secure and reliable video streaming.
