Capture unbekannten Stream mit GStreamer

Question

Ich habe eine IP-Kamera, die H264 Video über UDP streamen, aber ich kann es nicht mit Gstreamer in irgendeiner brauchbaren Qualität erfassen.

Mit diesem Befehl:

gst-launch-1.0.exe -vvv playbin uri=udp://192.168.1.66:30120 

ich das Bild von der Kamera, aber es hat Latenzzeit von mehreren Sekunden. Es produziert, um den fließenden Ausgangs:

Mit dieser Ausgabe habe ich versucht, eine alternative Pipeline zu schreiben, die bessere Ergebnisse produzieren würde. Bisher habe ich:

gst-launch-1.0.exe udpsrc port=30120 ! video/x-raw, packetsize=(int)188, format=(string)RGB16, width=(int)720, height=(int)480, framerate=(fraction)30/1 ! autovideosink 

aber das zeigt nur einen schwarzen Bildschirm. Und das:

gst-launch-1.0.exe -vvv udpsrc port=30120 ! video/x-raw, packetsize=(int)188, format=(string)I420, width=(int)720, height=(int)480, interlace-mode=(string)progressive, pixel-aspect-ratio=(fraction)1/1, chroma-site=(string)mpeg2, colorimetry=(string)bt601, framerate=(fraction)30/1 ! autovideosink 

zeigt nur einen grünen Bildschirm.

Was wäre die optimale Pipeline für meinen Stream? Ist das überhaupt möglich mit Gstreamer?

Vielen Dank im Voraus.

Lauf gst-Entdecker ich erhielt:

Wie schalte ich diese in eine Pipeline?

Answer 1

Sie können die unten Pipeline versuchen zur Aufnahme von H264-Streams auf UDP

gst-launch-1.0 udpsrc port=30120 caps="application/x-rtp, media=(string)video, 
clock-rate=(int)90000, encoding-name=(string)H264" ! rtpjitterbuffer ! 
rtph264depay ! avdec_h264 ! videoconvert ! autovideosink sync=false
