How to listen to and decode an RTMP video stream with Python

问题

如何使用Python监听并解码RTMP视频流,就像使用ffmpeg命令一样:

import av
container = av.open('rtmp://localhost:1935/live/app', options={'listen': True})
for frame in container.decode(video=0):
    frame = frame.to_ndarray(format='bgr24')
    # 对帧进行操作...

但是我遇到了一个错误:

open()收到了一个意外的关键字参数'listen'

How can I listen to and decode an RTMP video stream with Python? Such as with the ffmpeg command

`ffmpeg -listen 1 -i rtmp://localhost:1935/live/app`
I tried this:

import av
container = av.open('rtmp://localhost:1935/live/app',listen=True)
for frame in container.decode(video=0):
frame = frame.to_ndarray(format='bgr24')
...do some thing with the frame...


But I got an error:

&gt; open() got an unexpected keyword argument &#39;listen&#39;

**得分**: 0

```python
PyAV正确的语法是:

    container = av.open('rtmp://localhost:1935/live/app', options={'listen': '1'})

`av.open`接受一个`options`字典参数。
在代码中,`'listen'`是键,`'1'`是值。
这相当于FFmpeg CLI的`-listen 1`参数。
英文:

PyAV correct syntax is:

container = av.open(&#39;rtmp://localhost:1935/live/app&#39;, options={&#39;listen&#39;: &#39;1&#39;})

av.open accepts an options dictionary argument.
In the code, &#39;listen&#39; is the key and &#39;1&#39; is the value.
This is the equivalent to -listen 1 argument of FFmpeg CLI.
