Embodiment approach

[0148] As an implementation manner, the second creation submodule is specifically used for:

[0149] If the source data does not support hardware decoding and the transcoded data supports hardware encoding, then use the CPU to create a soft decoding thread, use a hardware chip to create a hard coding thread, and obtain the first thread including the soft decoding thread and the hard coding thread a hybrid transcoding module;

[0150] If the source data supports hardware decoding and the transcoded data does not support hardware encoding, use the CPU to create a soft encoding thread, use a hardware chip to create a hard decoding thread, and obtain the first thread including the soft encoding thread and the hard decoding thread Two hybrid transcoding modules.

[0151] As an implementation manner, the second creation submodule is specifically used for:

[0152] Utilize the CPU to create a soft decoding thread, use a hardware chip to create a hard-coded thread and a hard post-pr...

Abstract

The embodiment of the present application provides a data transcoding method and device. The method includes: using CPU and hardware chip to create multiple transcoding modules; dividing the source data corresponding to the transcoding task into multiple pieces of data to be transcoded; using the created The transcoding module transcodes the multiple data to be transcoded to obtain multiple temporary files; merges the multiple temporary files to obtain the transcoded data of the source data; it can be seen that in this solution, the CPU and hardware The transcoding module created by the chip performs transcoding, realizing the simultaneous use of CPU and hardware chip for transcoding, which improves the utilization rate of equipment.

Description

technical field [0001] The present invention relates to the field of multimedia technologies, in particular to a data transcoding method and device. Background technique [0002] In some scenarios, video data usually needs to be transcoded. For example, transcoding video data can be understood as converting a compressed and coded video code stream into another video code stream, so as to adapt to different network bandwidths, different terminal processing capabilities, and different user requirements. [0003] In some transcoding schemes, a CPU (Central Processing Unit, central processing unit) can be used to perform a transcoding operation, or a hardware chip, such as a GPU (Graphics Processing Unit, graphics processing unit), can also be used to perform a transcoding operation, but not at the same time Utilize CPU and hardware chips for transcoding operations, and the device utilization rate is low. Contents of the invention [0004] The purpose of the embodiments of t...
