Function: vdec_set_channel_desc_out_mode

aclError aclvdecSetChannelDescOutMode(aclvdecChannelDesc *channelDesc, uint32_t outMode)

ret = acl.media.vdec_set_channel_desc_out_mode(vdec_channel_desc, out_mode)

Sets the decoding channel description attribute: whether to output frames in real time.

vdec_channel_desc: int, description of the video decoding channel.

Call acl.media.vdec_create_channel_desc to create data of the aclvdecChannelDesc type in advance.

out_mode: int, frame output mode, to set whether to output frames in real time. Values:

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

• 1: real-time frame output mode. 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).

ret: int, error code.

• 0 indicates success.
• Other values indicate failure.
