Hi, all!
I'm on Windows and I have a video in MJPEG format. ffmpeg shows the following information about it:
Input #0, matroska,webm, from 'D:\Movies\1920x1080\mjpeg_1920x1080.mkv':
  Metadata:
    ENCODER         : Lavf58.12.100
  Duration: 00:01:12.24, start: 0.000000, bitrate: 15763 kb/s
  Stream #0:0: Video: mjpeg (Baseline), yuvj420p(pc, bt470bg/unknown/unknown), 1920x1080 [SAR 1:1 DAR 16:9], 25 fps, 25 tbr, 1k tbn (default)
    Metadata:
      ENCODER         : Lavc58.18.100 mjpeg
      DURATION        : 00:01:12.240000000
I can play it correctly using the command:
.\gst-launch-1.0.exe filesrc location=D:/Movies/1920x1080/mjpeg_1920x1080.mkv ! matroskademux ! jpegparse ! jpegdec ! videoconvert ! autovideosink
But if I try to send the file as an RTP stream and then receive it, the resulting picture is completely broken. Here are the commands:
.\gst-launch-1.0.exe filesrc location=D:/Movies/1920x1080/mjpeg_1920x1080.mkv ! matroskademux ! jpegparse ! rtpjpegpay ! udpsink host=127.0.0.1 port=5000

.\gst-launch-1.0.exe udpsrc uri=udp://127.0.0.1:5000 caps="application/x-rtp, media=video, encoding-name=JPEG" ! rtpjpegdepay ! jpegparse ! jpegdec ! videoconvert ! autovideosink
Could you please advise me what could be the problem?
