gstreamer：m3u8到mkv /运动视频失败

Question

我想将m3u8流摄取到运动视频（MKV格式）。我编译了kvssink插件，但gstreamer失败，出现未知错误。

也许在发送到kvssink之前，我需要以某种方式转换流？有人可以对此发表评论吗？

命令：

gst-launch-1.0 souphttpsrc  location=http://devimages.apple.com/iphone/samples/bipbop/gear4/prog_index.m3u8 ! hlsdemux ! video/x-h264, format=avc,alignment=au ! h264parse ! kvssink stream-name="my-stream" storage-size=128 access-key="<key>" secret-key="<secret>"

错误

Answer 1

video/x-h264, format=avc,alignment=au我认为您不能以这种方式来规定上限。它只会妨碍自动协商上限。
