Problems solved by technology

[0004] However, in this parallel forwarding scheme, the hardware involved in transcoding, such as CPU, GPU, and dedicated video codec chips, are used in different links of transcoding, resulting in only one kind of hardware performing transcoding operations at the same time, while other hardware is in the process of transcoding. Waiting state, resulting in low utilization of transcoding resources

Embodiment Construction

[0055] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0056] refer to figure 1, is an implementation flowchart of a transcoding control method provided in Embodiment 1 of the present application. This method can be applied to an electronic device that has multiple transcoding components and can control the transcoding components to transcode the video stream, such as Mobile phones, pads, virtual reality VR (Virtual Reality) glasses or augmented reality AR (Augmented Reality) glasses, etc. The transcoding component may include a centra...

Abstract

The invention discloses a transcoding control method and apparatus, and an electronic device. The method comprises the steps of obtaining a to-be-transcoded video stream; carrying out frame segmentation on the video stream to obtain a plurality of image groups, wherein each image group comprises at least one frame of image; performing transcoding processing on the image group in parallel by utilizing a plurality of transcoding threads created on the electronic equipment; wherein one transcoding thread corresponds to one transcoding component on the electronic equipment, so that the plurality of transcoding threads can perform transcoding processing on the image group in parallel through the respective corresponding transcoding components. Visibly, the image in the video stream is subjectedto frame segmentation, and then the plurality of transcoding threads are used for transcoding each segmented image group in parallel through the respective corresponding transcoding component, so that the plurality of transcoding components can be operated in parallel at the same moment to perform transcoding operation; therefore, the transcoding component is prevented from being idle, and the utilization rate of the transcoding component is improved.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular to a transcoding control method, device and electronic equipment. Background technique [0002] Audio and video transcoding is a key technology in the field of live broadcast, on-demand, short video, and video conferencing. In recent years, with the rise of live broadcast and video websites, video transcoding technology has been widely concerned and applied. Ordinary live broadcast or on-demand video requires a frame rate of At 25-30fps, the resolution is 480P-1080P. Compared with ordinary video live broadcasting, VR live broadcasting usually requires a video frame rate of 60-120fps and a resolution of 2K-8K. The computing power required for VR video transcoding is much higher than Ordinary video transcoding, and VR or game live broadcast requires higher network bandwidth and lower operation delay, so in order to reduce the video transmission distance, it is us...
