I would propose: media: mediatek: vcodec: Avoid unneeded error logging Since the LAT decoder works faster than its CORE, getting the trans buffer may be done only after CORE finishes processing: avoid printing an error if the decode function returns -EAGAIN, as this means that the buffer from CORE is not yet available, but will be at a later time. Also change the log level for calls to vdec_msg_queue_dqbuf() in H264 and VP9 LAT decoder drivers to avoid excessive logging. Cheers, Angelo
Hi AngeloGioacchino, Thanks for your suggestion.

The speed of lat decoder is much faster than core, need to get trans buffer again when lat fail to get trans buffer.
