I am writing frame by frame to the VideoWriter Object using the appsrc of gstreamer to stream to the rtmp link alongwith the audio. But I am unable to receive the audio at the rtmp endpoint only video is streaming
```auto
cv2.VideoWriter (filesrc location="C:/Users/gmura/Downloads/audio_2024-05-14 12_49_20.wav" ! mpegaudioparse ! avdec_mp3 ! audioconvert ! audioresample ! queue ! mux. filesrc location="C:/Users/gmura/Downloads/video_2024-05-15 18_26_17.mp4" ! qtdemux ! queue ! avdec_h264 ! videoconvert ! x264enc tune=zerolatency ! queue max-size-buffers=1 leaky=downstream ! mux. flvmux name=mux streamable=true ! rtmpsink location="rtmp://122.166.44.132:1935/yolo/live live=true" sync=false, cv2.CAP_GSTREAMER, cv2.VideoWriter_fourcc(*'H264'), fps,(frame_w, frame_h ))
```

OpenCV doesn’t support Audio.
Well it does, kinda, but that was some GSoC project and they had to work around the existing APIs, which means the existing API is video-only.
if you have an issue with gstreamer pipelines, that’s a gstreamer issue. reproduce without OpenCV, just with gstreamer on the command line.

The gstreamer pipeline works well, it doesn’t work when we integrate with the opencv VideoWriter Object
