器件型号：AM62A7-Q1

工具与软件：

您好！

当我运行以下脚本将视频从 AR0823流式传输到以太网(使用 VISS 和 LDC 的 VPAC)时、我只能获得22fps、而 tiperfoverlay 使用48-49%的数据显示 VISS 和 LDC。

#!/bin/bash

TEMP=$(getopt -o 'p:l:b:h' --long 'profile:,level:,bitrate:,input:,output:,help,mc:,port:' -n '$0' -- "$@")

if [ $? -ne 0 ]; then
	echo 'Terminating...' >&2
	exit 1
fi

eval set -- "$TEMP"
unset TEMP

while true; do
	case "$1" in

当我移除 LDC 时、tiperfoverlay 展示了 VISS 68%的 CPU 使用率。

VPAC 是否支持3840x2160 @ 30fps？如果是、如何提高第一个流水线的帧速率？

您好、Bas、

请使用 SDK 10.01.00.05 (当前版本)： www.ti.com/.../PROCESSOR-SDK-AM62A。

谢谢！
