Description

Multimedia data stream switching method and device, storage medium and electronic device

Technical Field

The present invention relates to the field of computers, and in particular, to a multimedia data stream switching method, device, storage medium, and electronic device.

Background

With the network popularization and the pursuit of people in the mental level, the live broadcast is already at the wind gap wave tip, the video source of the live broadcast can be various, including the collection of hardware equipment, local files, network flows and the like, wherein different video sources and resolutions can also be various. In real-time live broadcasting requiring interaction, the delay of audio and video caused by switching of resolution ratio directly affects the experience of users, and the influence is more serious under the condition of bidirectional interaction.

In the current live broadcast process, the resolution of the video stream is usually fixed at the beginning of live broadcast or push stream, and the resolution of the video stream is not changed until the end of live broadcast or push stream, if the resolution needs to be modified, the live broadcast or push stream needs to be ended, and after the resolution is reset, the live broadcast or push stream is restarted.

This results in the following disadvantages in the current live broadcast resolution switching scheme:

1) the anchor end/stream pushing party needs to restart the live broadcast/stream pushing, which directly causes the interruption of the video stream in the live broadcast or stream pushing process;

2) the spectator/streamers cannot predict the stream interruption and after the interruption, it cannot be determined whether the anchor/streamers are actually finished or the finishing process in restarting the resolution. The following problems may arise:

A) the anchor/plug is really over, and the viewer/plug is waiting for reconnection as an interrupt process, and user interaction may require long time for showing reconnection waiting until the timeout is over or no response, in addition to performance consumption.

B) The anchor/plug-flow party is a restart interrupt, and the viewer/plug-flow party is treated as a true end, so that no reconnection operation is performed, and manual operation is required to connect the flow again after the restart.

C) If the anchor terminal/stream pushing party is a restart interrupt, and the viewer terminal/stream receiving party is used as a restart interrupt process, a long-time reconnection process may be performed before reconnection is successful, and in addition to performance consumption, user interaction may require long-time display of reconnection waiting until reconnection succeeds in acquiring a new video stream or timeout ends.

Because of the shortcomings of the prior art, both the anchor/plug-flow side and the viewer/plug-flow side will bring poor user experience, and the manual negotiation and operation are not required in the whole switching process.

In view of the above problems, no effective solution has been proposed.
