Video gstreamer pipline产生慢动作（低FPS）视频

我想连接到HTTP MJPEG实时流，并将其作为视频文件本地转储。所以我做了：

$gst发布-vvv souphttpsrc位置=http://bikersschool.dyndns.org/video.cgi?resolution=vga is live=true do timestamp=true！多方数据交换！jpegdec！视频速率！视频/x-raw-yuv，帧速率=60/1！Theoreanc！oggmux！filesink location=hi.ogg

但是，在播放hi.ogg时，视频的运动速度较慢

这是它产生的结果：

更新：

我试着放下录像带和caps过滤器。但它失败了，并显示以下消息：

视频收费的目的是什么！视频/x-raw-yuv，帧速率=60/1

---

从技术上讲，videorate将复制掉帧，使输出速率达到60fps。如果你放弃录像带怎么办！capsfilter？gst为jpegdec的封顶推出了什么打印功能？

删除videorate和caps过滤器会导致失败。我无法在评论中格式化，所以我把信息放在了原始问题中。你能回答另一个问题吗。jpegdec上的fps是什么？另外，尝试在capsfilter中输入一个真实的fps，例如30fps，或者您的流真的是60fps？如果删除视频速率和caps过滤器，则会导致失败。我无法在评论中格式化，所以我把信息放在了原始问题中。你能回答另一个问题吗。jpegdec上的fps是什么？同时尝试将一个真实的fps放入capsfilter，例如30fps，或者你的流真的是60fps？
