Embodiment 1

[0094] Such as figure 1 As shown, a video conference system includes a switch, an MCU, an RTMP live broadcast device, and an audio quality diagnosis system; the switch, the RTMP live broadcast device, and the audio quality diagnosis system are connected in sequence; the MCU is connected to the switch, and the switch The original stream audio data is received and processed. The MCU sends out instruction signals to control the switch. The switch sends the processed original stream audio data to the RTMP live broadcast device through port mirroring, and the RTMP live broadcast device will process the original The streaming audio data is sent to the audio quality diagnosis system according to the Real Time Messaging Protocol (RTMP), and various indicators of the audio data are diagnosed, the audio quality is judged according to the diagnosis result, and the audio quality diagnosis result is output.

[0095] The audio quality diagnosis system includes:

[0096] Obtain the original strea...

Embodiment 2

[0103] Such as figure 2 As shown, an audio quality diagnosis method includes the following steps:

[0104] Step 1: Obtain the original stream data; perform port mirroring on the switch connected to the MCU in the video conferencing system, obtain the original stream data in the meeting, and use the RTMP live broadcast device to push the original stream data in RTMP;

[0105] Step 2: Obtain audio stream data; use the FFMPEG computer program to decode and transcode the original stream data pushed by RTMP in step 1, to obtain audio stream data;

[0106] The FFMPEG computer program is an open source computer program used to record and convert digital audio and video, and convert them into streams.

[0107] Step 3: Obtain audio frames; divide the audio stream data in step 2 according to time segments to obtain audio frame data of different segments;

[0108] Step 4: Audio diagnosis; perform audio diagnosis on the indicators of the audio frame data in step 3, judge the audio quality accordin...
