如何使用gstreamer从USB视频捕获+ dvb设备中抓取视频? [英] how can I grab video from usb video capture + dvb device with gstreamer?

问题描述

我拥有一个avermedia volar HX usb记忆棒，我想从复合输入中捕获，但是不能，因为我无法选择输入.我正在使用带有+ python的gstreamer，我想我需要使用gsttuner select输入，但是我没有使用gstreamer界面的经验.有人可以张贴一个简单的例子吗?

I own a avermedia volar HX usb stick, I want to capture fromthe composite input , but I can't because I'm unable to select the input. I'm using gstreamer with + python, I think I need to use gsttuner select input but I have no experience using gstreamer's interfaces. Could someone post a simple example?

谢谢！

推荐答案

对于任何对此绊脚石的人，自最初发布以来，一些内部gstreamer更改可能现在需要gst.STATE_READY而不是STATE_PAUSED.令我震惊的是，似乎我遇到的一半捕获设备默认为PAL，我需要使用GST_TUNER接口进行更改.

To anyone stumbling on this, some internal gstreamer changes since this was originally posted may require gst.STATE_READY now instead of STATE_PAUSED. Tripped me up as it seems half the capture devices I encounter default to PAL and I need to use the GST_TUNER interface to change it.
