缺少 AppSink 方法：AttributeError: 'GstAppSink'

Question

我正在尝试使用 AppSink 接收器从中读取样本，但该对象上似乎不存在任何 AppSink 方法。

import gi

gi.require_version("Gst", "1.0")

from gi.repository import Gst

Gst.init()

pipe = Gst.parse_launch("audiotestsrc ! opusenc ! appsink name=sink")

sink = pipe.get_by_name("sink")

while not sink.is_eos():

    pass

错误

Traceback (most recent call last):

  File "x.py", line 9, in <module>

    while not sink.is_eos():

AttributeError: 'GstAppSink' object has no attribute 'is_eos'

gstreamer 版本：

gst-inspect-1.0 version 1.14.1

GStreamer 1.14.1

该appsink接口位于与基本 GStreamer 不同的库中。您还需要导入GstApp：import gigi.require_version("Gst", "1.0")gi.require_version("GstApp", "1.0")from gi.repository import Gst, GstAppGst.init(None)pipe = Gst.parse_launch("audiotestsrc ! opusenc ! appsink name=sink")sink = pipe.get_by_name("sink")while not sink.is_eos():&nbsp; &nbsp; pass
