Embodiment

[0076] Such as figure 1 The flow chart of the method for multi-layer video dynamic coding in the cloud conference shown, the present invention includes the following steps,

[0077] S1: Open the shared video in the cloud meeting; select the best collection capability set and set the collection parameters; send the collected video data to the video collection module through the callback function for processing; make the real-time update of the collection output frame rate according to the channel state;

[0078] S2: Establish a shared video multi-layer video encoding thread, take valid data from the acquisition queue for encoding processing, so that the encoding parameters can be updated in real time according to the channel status;

[0079] S3: Create a shared multi-layer video package sending thread, create a channel status monitoring thread, and when the channel status receives effective feedback, parse out the data and put it into the status queue;

[0080] S4: Establish a...

Abstract

The invention relates to the technical field of video conferences, in particular to a multi-layer video dynamic coding method in a cloud conference, which comprises the following steps of: updating and acquiring an output frame rate in real time according to a channel state; updating coding parameters in real time according to the channel state; establishing a shared multi-layer video packaging and sending thread, creating a channel state monitoring thread, and when a channel state receives effective feedback, analyzing data and putting the data into a state queue; and establishing a dynamic mechanism and an analysis thread, taking out the current channel state from the state queue, carrying out data normalization processing, and calling the obtained acquisition frequency and coding parameters back to an acquisition thread and a coding thread for processing. According to the method for dynamically coding the multi-layer video in the cloud conference disclosed by the invention, the transmission data volume can be dynamically adjusted according to the transmission channel state, and the stable transmission of the multi-layer video in the current channel is ensured.

Description

technical field [0001] The invention relates to the technical field of video conferencing, in particular to a method for dynamically encoding multi-layer videos in a cloud conference. Background technique [0002] In existing video conferencing methods for multi-layer video transmission during channel changes, one is to request a single-layer video at the viewing end, and request a video with a smaller layer resolution and bit rate according to the current channel change, which is relatively easy to implement, but when There is a small amount of packet loss at equal intervals on the network, and the frequent switching of videos on the viewing end results in blurring and clearing for a while, affecting viewing and affecting user experience. The other is that the resolution requested by the viewing end is sent to the sharing end through the server, and the sharing end detects that it does not match the current encoding resolution, and rebuilds an encoder with a new resolution ...
