the judgment unit is used for judging whether the current decoding method can Decode the test Video, if the current decoding method can Decode the test Video, detecting whether the GPU-Video Decode utilization rate corresponding to the current decoding method is increased, if so, calling the next decoding method to Decode and judge whether the next decoding method can Decode the test Video, and if not, recording the current decoding method as an equipment hardware accelerated decoding method to obtain a first judgment result that the equipment can perform hardware accelerated decoding.
8. A terminal device, comprising: a processor and a memory, and a control unit,
the memory has a computer program stored therein and configured to be executed by the processor, the processor implementing the audio/video hardware accelerated transcoding detection method as claimed in any of claims 1 to 5 when executing the computer program.
9. A computer-readable storage medium, on which a computer program is stored, the computer program being executable by a processor to implement the method for audio video hardware accelerated transcoding detection as claimed in any of claims 1 to 5.
