Abstract

The invention discloses an optimization method based on android using WebRtc plug flow. According to the invention, after the modified source code is packaged into so, the so is quoted for java, after the business logic is processed, the so is packaged into apk and is installed on a server, and after the client is connected with the server, the experience effect can be achieved. By adopting the optimization method provided by the invention to optimize, the packet grabbing condition is more stable through comparison, the condition of unsmooth operation of the terminal is avoided, and the user experience is ensured.

Description

Optimization method based on android using WebRtc plug flow

Technical Field

The invention relates to the technical field of cloud mobile phones and cloud games, in particular to an optimization method for using WebRtc plug flow based on android.

Background

When the android server uses WebRtc to push, even if the network condition is good and the CPU performance is enough, the phenomenon of jamming and frame loss still occurs when the picture changes too fast, and the terminal has bad experiences such as unsmooth operation. At present, most of optimization methods use NACK optimization, dynamic adjustment of jitter buffer size, FEC/RED optimization and the like at a receiving end, so that the actual effect is not very good.

Accordingly, the prior art has drawbacks and needs improvement.

Disclosure of Invention

The invention aims to overcome the defects of the prior art, provides an optimization method for using WebRtc plug flow based on android, mainly optimizes a server side WebRtc plug flow algorithm, and aims at reducing the interval of sending RTP packets so as to achieve the effect of reducing delay and jitter buffer values.

The technical scheme of the invention is as follows: the optimization method based on android using WebRtc plug flow is characterized by comprising the following steps:

step 1: downloading WebRtc source codes to a Linux system, compiling the source codes into a so library, and then calling the so library to an android system;

step 2: the JAVA is adopted to send the audio and video tracks separately, so that information congestion is avoided;

step 3: the data is processed through the video stream encoding module without losing packets;

step 4: after the packet loss prevention processing is completed, the paging module does not judge the buffer queue data any more, and the buffer queue data are immediately sent out when the data are inserted;

step 5: after compiling the source code into so again, the java is called.

Further, the JAVA code is set to H264 code.

By adopting the scheme, the invention mainly reduces the delay of the WebRtc in transmission, reduces the jitter buffer value and enables the experience to be smoother when the terminals are connected.

Detailed Description

The invention will be described in detail below with reference to the drawings and the specific embodiments.

Referring to fig. 1, the invention provides an optimization method based on android using WebRtc plug flow, which is characterized by comprising the following steps:

step 1: downloading the WebRtc source code to a Linux system, compiling the WebRtc source code into a so library, and then calling the so library to an android system.

Step 2: the JAVA code is set to H264 code. And the JAVA is adopted to send the audio and video tracks separately, so that information congestion is avoided.

Step 3: and carrying out non-packet loss processing on the data through a video stream encoding module.

Step 4: after the packet loss prevention processing is completed, the paging module does not judge the buffer queue data any more, and the buffer queue data are immediately sent out when the data are inserted, so that the size of the server buffer RTP packet is reduced.

Step 5: after compiling the source code into so again, the java is called.

Taking 30fps as an example, before the packet is captured under the same environment, the packet capturing situation is shown in fig. 2, and the chart of the jitter buffer is shown in fig. 3. By adopting the optimization method provided by the invention to optimize, the packet grabbing condition is more stable through comparison, the condition of unsmooth operation of the terminal is avoided, and the user experience is ensured.

The foregoing description of the preferred embodiment of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
