如何使用 gst-python 生成音频流？
我希望在 gstreamer 中生成流，如果可能的话，我更愿意从 python 中生成流。这指向使用 gst-python，但我没有看到明确的方法。看起来创建一个新流需要制作一个 gstreamer 插件，而 gst-python 似乎无法做到这一点。
为了澄清，我希望能够生成传递给声卡的实际值，例如，允许我制作正弦曲线音调。我不想使用内置的 python OSS 支持，因为它有点过时，并且锁定 /dev/dsp。
有人建议尝试一下吗？或者甚至另一个（现代）音响系统可以做到这一点？
I'm looking to generate a stream in gstreamer, and I'd prefer to do it from python if possible. This points towards using gst-python, but I don't see a clear way to do it. It looks like creating a new stream would require making a gstreamer plugin, which gst-python doesn't seem to be able to do.
To clarify, I'd like to be able to generate the actual values getting handed to the sound card, allowing me to, for example, make a sine-curve tone. I don't want to use the built-in python OSS support, as it's a bit outdated, and locks /dev/dsp.
Does anyone have a suggestion of something to try? Or even another (modern) sound system that can do this?

appsrc(gst-inspect appsrc)。我使用其对应的appsink从 gstreamer 管道中获取数据。这是一个（几乎）有效的示例。 http://gstreamer-devel.966125.n4。 nabble.com/appsrc-random-crash-td973529.html
Take a look at
appsrc(gst-inspect appsrc). I used its counterpartappsinkto get data out of a gstreamer pipeline.And here's an (almost)-working example. http://gstreamer-devel.966125.n4.nabble.com/appsrc-random-crash-td973529.html
