问题描述
我正在尝试使用GStreamer通过UDP接收h264流。然后，我以4-2-2较高的配置文件对收到的视频进行编码。然后将其发送到我的dvr计算机。但是在这些过程中，我收到各种错误和警告。结果，在我的dvr计算机上创建的视频没有前10秒。当我使用VLC媒体播放器打开视频时，屏幕上出现黑色图像10秒钟。然后VLC继续播放视频。但是我看不到前10秒。这10秒的时间值会改变。
我的问题是我该如何改善录制流畅而完整的视频而又没有缺陷的渠道？

我使用的管道：
udpsrc port={PORT} buffer-size=100000000 ! queue ! tsdemux parse-private-sections=TRUE ! h264parse ! avdec_h264 ! videoconvert ! x264enc ! capsfilter caps=video/x-h264,profile=(string)high-4:2:2 ! mpegtsmux ! udpsink host={DVR_IP} port={DVR_PORT} sync=FALSE
我尝试了什么：
我使用下面给出的gstreamer管道而不是VLC打开了生成的视频文件。再次在视频开头播放了几秒钟。
视频播放非常快。一分钟之内，视频播放了2分钟。
gst-launch-1.0 filesrc location=5-1602155127551.ts ! queue ! video/mpegts ! tsdemux ! h264parse ! queue2 ! avdec_h264 ! videoconvert ! autovideosink sync=false
视频播放非常慢。一分钟之内，视频播放了40秒。
