Question

我想连接到HTTP MJPEG直播流并将其作为视频文件在本地转储。所以我做了：

$ gst-launch -vvv souphttpsrc location = http：//bikersschool.dyndns.org/video.cgi？resolution = vga is-live = true do-timestamp = true！ multipartdemux！ jpegdec！视频！ video / x-raw-yuv，帧率= 60/1！ theoraenc！ oggmux！ filesink location =“hi.ogg”

然而，在播放hi.ogg时，视频是慢动作的。

这是它产生的a sample video：

我尝试删除视频和大写过滤器。但它失败了以下消息：

$ gst-launch -vvv souphttpsrc location = http：//bikersschool.dyndns.org/video.cgi？resolution = vga is-live = true do-timestamp = true！ multipartdemux！ jpegdec！ theoraenc！ oggmux！ filesink location =“hi.ogg”

Answer 1

视频的目的是什么！ video / x-raw-yuv，framerate = 60/1？

技术上，视频速率将复制丢帧，使输出速率为60fps。如果你放弃视频，怎么办？ capsfilter？什么是gst-launch打印jpegdec的上限？

gstreamer管道产生慢动作（低FPS）视频
