我有以下GStreamer命令正常工作:
1°)通过TCP传输2个MJPEG流:
gst-launch-1.0 v4l2src device=/dev/video0 ! deinterlace mode=1 ! videorate ! videoscale ! tee name=tp \
\
tp. ! queue ! video/x-raw, framerate=10/1, width=960, height=540 ! jpegenc quality=40 ! multipartmux ! tcpserversink host=0.0.0.0 port=8093 \
\
tp. ! queue ! video/x-raw, framerate=15/1, width=960, height=540 ! jpegenc quality=40 ! multipartmux ! tcpserversink host=0.0.0.0 port=8096
2°)通过TCP传输2个MP4流:
gst-launch-1.0 v4l2src device=/dev/video0 ! deinterlace mode=1 ! videorate ! videoscale ! tee name=tp \
\
tp. ! queue ! video/x-raw, framerate=10/1, width=960, height=540 ! x264enc bitrate=1000 ! mpegtsmux ! tcpserversink host=0.0.0.0 port=8093 \
\
tp. ! queue ! video/x-raw, framerate=15/1, width=960, height=540 ! x264enc bitrate=1000 ! mpegtsmux ! tcpserversink host=0.0.0.0 port=8096
但是这个没有(尝试通过TCP流式传输1个MJPEG流和1个MP4流):
gst-launch-1.0 v4l2src device=/dev/video0 ! deinterlace mode=1 ! videorate ! videoscale ! tee name=tp \
\
tp. ! queue ! video/x-raw, framerate=10/1, width=960, height=540 ! jpegenc quality=40 ! multipartmux ! tcpserversink host=0.0.0.0 port=8093 \
\
tp. ! queue ! video/x-raw, framerate=15/1, width=960, height=540 ! x264enc bitrate=1000 ! mpegtsmux ! tcpserversink host=0.0.0.0 port=8096
命令行说:
Setting pipeline to PAUSED ...
Pipeline is live and does not need PREROLL ...
Setting pipeline to PLAYING ...
New clock: GstSystemClock
Redistribute latency...
听起来不错,但是我无法在VLC中播放流(它正在使用第一个命令行)。
唯一的变化就是我替换了一个流:
jpegenc quality=40 ! multipartmux
by:
x264enc bitrate=1000 ! mpegtsmux
任何帮助将不胜感激......

答案 0 :(得分:1)
使用" x264enc tune = zerolatency"让它发挥作用!
