Embodiment 1

[0033] figure 1 It is a schematic flowchart of a real-time video transmission method provided by Embodiment 1 of the present invention. The method is applicable to real-time video transmission, and the method can be executed by a real-time video transmission device, which can be composed of hardware and / or software, and can generally be integrated at the video sending end and all intelligent terminals that include video sending functions middle. Specifically include the following:

[0034] S110. Segment the encoded video frame generated in real time to form at least one video frame segment.

[0035] Optionally, after the real-time video data is collected by a video capture device such as a camera, a video encoder can be used to perform real-time encoding processing on the real-time video data to form a video encoding frame, and for a high-resolution video encoding frame, the size of the frame is often It is higher than the maximum network transmission unit in the transmissi...

Embodiment 2

[0048] figure 2 It is a schematic flowchart of a real-time video transmission method provided by Embodiment 2 of the present invention. This embodiment is optimized on the basis of the above embodiments, and provides a preferred real-time video transmission method. Specifically, further optimization is performed after the video frame fragments are sequentially put into the sending buffer. Specifically include the following:

[0049] S210. Segment the encoded video frame generated in real time to form at least one video frame segment.

[0050] S220. Put the video frame fragments into the sending buffer in sequence.

[0051] S230. Periodically check whether the sending buffer includes expired video frame fragments whose existence time exceeds a preset time threshold, if yes, perform S240; if not, perform S260.

[0052] Wherein, the checking period may be 10s, and the preset time threshold may be set according to the video playing time of the video playing terminal. When the...

Abstract

The embodiment of the invention discloses a real-time video transmission method and apparatus. The method comprises the following steps: performing fragmentation processing on a real-time generated video encoding frame to form at least one video frame fragment; placing the video frame fragments into a sending buffer area in sequence; and forwarding the video frame fragments of the video encoding frame to a video playing terminal according to a set sending strategy via a video server in accordance with receiving confirmation response returned by the video playing terminal for different video frame fragments, in order to perform real-time video playing. By adoption of the technical solution of the invention, the video transmission delay can be shortened, the video transmission reliability can be improved, and the user experience can be improved.

Description

technical field [0001] Embodiments of the present invention relate to information processing technologies, and in particular, to a real-time video transmission method and device. Background technique [0002] With the continuous popularization and development of the Internet, mobile Internet video live streaming is in full swing. Most of the traditional live broadcasts are one-way. For example, TV stations or operators broadcast live broadcasts. Users only need to turn on the terminal to watch, and there are not too many requirements for real-time performance. On the other hand, mobile Internet video live broadcast often requires interaction between the recording end and the playback end in terms of functions. This interaction is not limited to text interaction, but also includes video interaction. Therefore, mobile Internet video live broadcast has higher real-time requirements. [0003] At present, the data interaction method of real-time video in mobile Internet live vid...
