the coding method judging unit is used for judging whether the current coding method can code the test Video, if the current coding method can code the test Video, detecting whether the GPU-Video decoding rate corresponding to the current coding method is increased, if not, calling the next coding method to code and judging whether the next coding method can code the test Video, and if so, recording the current coding method as a hardware acceleration coding method of the equipment, and obtaining a first judging result as the hardware acceleration coding of the equipment.
5. A terminal device, comprising: a processor and a memory are provided for the processor,
the memory stores a computer program, and the computer program is configured to be executed by the processor, which when executing the computer program, implements the audio-video hardware accelerated transcoding detection method as claimed in any one of claims 1 to 3.
6. A computer readable storage medium having stored thereon a computer program, wherein the computer program is executed by a processor to implement the audio-video hardware accelerated transcoding detection method of any of claims 1 to 3.
