Return Value

Description

out_mode

Int, frame output mode, to set whether to output frames in real time.

The options are as follows:

  • 0: delayed frame output mode. The VDEC starts to output the decoding result only after receiving multiple frames in the stream.

  • 1: real-time frame output mode. The VDEC starts to output the decoding result in real time after obtaining a frame in the stream. Only H.264/H.265 standard streams with simple reference relationships are supported (no long-term reference frames or B-frames).
