在设计中,常常为了控制是否需要正常译码,在Decoder输入端加入一个使能端,用于控制是否正常进行译码,下图是带有使能端的3line-8line译码器,当使能端位高电平时,该译码器电路进行正常工作,反之译码器输出端都为无效信号; gate-level 3line-8line Decoder with enable input 使能端(enable)在组合逻辑电路中有时非常方便...
The-c:v h264_rkmpp -i INPUTcan be omitted since in FFmpeg 6.0 and up,-hwaccel rkmppwill pick up the required decoder automatically. Decode but not copy-back. Without AFBC (ARM Frame Buffer Compression). ./ffmpeg -stream_loop -1 -hwaccel rkmpp -hwaccel_output_format drm_prime -i /pa...
pBufferDesc参数指向一个或多个D3DWDDM2_4DDI_VIDEO_DECODER_BUFFER_DESC结构的数组。 数组中的每个元素描述一个压缩的视频帧缓冲区,该缓冲区提交用于解码。 每个D3DWDDM2_4DDI_VIDEO_DECODER_BUFFER_DESC结构包括以下数据: 将接收解密和解码帧缓冲区的资源。

The rdforce inputs of both decoders must be tied high. To enable cascaded decoding, the data paths fed by the rdin and rdforce inputs are not cascaded. If these inputs are to be used in non- cascaded decoders, they should be delayed by one clock cycle with respect to their ...
