Embodiment 1

[0101] refer to Figure 5 , shows a flowchart of steps of a video transcoding method according to Embodiment 1 of the present invention. The method can be applied to the Internet of Vision, and the Internet of Vision can include a streaming media server of the Internet of Vision, a transcoding server and multiple transcoding devices.

[0102] The video transcoding method of the embodiment of the present invention may include the following steps:

[0103] Step 501, the target transcoding device receives a transcoding request sent by a transcoding server.

[0104] In the embodiment of the present invention, it is considered that if a transcoding device is set and the transcoding device can realize transcoding of various code rates, then the transcoding device receives the video stream to be transcoded each time, It is necessary to allocate a transcoding instance for processing the video stream to be transcoded first, and initialize the transcoding instance so that it can trans...

Embodiment 2

[0117] refer to Figure 6 , shows a flow chart of steps of a video transcoding method according to Embodiment 2 of the present invention.

[0118] The video transcoding method of the embodiment of the present invention can be applied to the Internet of Video. Figure 7 It is a schematic diagram of device interaction for video transcoding according to Embodiment 2 of the present invention. The Internet of Vision may include a streaming media server of the Internet of Vision, a transcoding server and multiple transcoding devices, and the streaming media server of the Internet of Vision integrates the transcoding server. The Internet-based streaming media server and transcoding server can realize two-way interaction based on the Internet protocol; the transcoding server and each transcoding device can realize two-way interaction based on the Internet protocol, and can specifically exchange information such as signaling; the Internet-based streaming media server and each transcod...

Embodiment 3

[0164] refer to Figure 8 , shows a structural block diagram of a video transcoding apparatus according to Embodiment 3 of the present invention. The device can be applied to the Internet of Vision, and the Internet of Vision includes a streaming media server of the Internet of Vision, a transcoding server and multiple transcoding devices, and the multiple transcoding devices include a target transcoding device.

[0165] The video transcoding apparatus of the embodiment of the present invention may include the following modules located in the target transcoding device:

[0166] A request receiving module 801, configured to receive a transcoding request sent by the transcoding server; the target transcoding device is determined by the transcoding server according to the transcoding request;

[0167] The data receiving module 802 is used to receive the video data packet to be transcoded according to the information of the target transcoding device sent by the Internet of View s...

Abstract

The invention provides a video transcoding method and device, being applied to an articulated naturality web. The video transcoding method comprises the steps that a target transcoding device receivesa transcoding request sent by a transcoding server, and the target transcoding device is determined by the transcoding server according to the transcoding request; the target transcoding device receives a to-be-transcoded video data packet sent by the articulated naturality web streaming media server according to the information of the target transcoding device, wherein the information of the target transcoding device is reported to the articulated naturality web streaming media server by the transcoding server; the target transcoding device sorts the video data packets to be transcoded; andthe target transcoding device transcodes the sorted video data packets according to the transcoding request, and sends the transcoded video data packets to an articulated naturality web streaming media server. According to the video transcoding method, the phenomena of time delay, packet loss, blurred screen, lagging, black screen and the like caused by poor terminal performance can be avoided; and the problem of disorder of the video data packets is solved, and the phenomena of jamming, blurred screen and the like caused by disorder of the video data packets are avoided, so that the user experience is improved.

Description

technical field [0001] The present invention relates to the field of video networking technologies, in particular to a video transcoding method and a video transcoding device. Background technique [0002] With the rapid development of network technology, two-way communications such as video conferencing and video teaching are widely used in users' life, work, and study. [0003] In the communication process, various types of terminal equipment appear in large numbers in response to demand, and the types of terminal equipment are uneven and their performances are different. In real-time video and audio services, the transmitted video streams are basically high bit rate video streams such as 720p and 1080p. Therefore, for terminal devices with low performance (such as mobile phones), they cannot quickly process these high-bit-rate video streams, which will lead to delays, packet loss, blurred screens, freezes, and even black screens, which will reduce user experience. Cont...
