ffplay 嵌入

没成功：

方法 1：自己编译支持 -xid 的 ffmpeg（最彻底）

这个是开发者常用的方案，一劳永逸：

这个是开发者常用的方案，一劳永逸：sudo apt install build-essential yasm pkg-config libx11-dev libsdl2-dev libxext-dev libxv-dev
git clone https://git.ffmpeg.org/ffmpeg.git ffmpeg
cd ffmpeg
./configure --enable-gpl --enable-sdl2 --enable-libx11 --enable-x11grab --enable-opengl --enable-libx264
make -j$(nproc)
sudo make install

#!/usr/bin/env bash
set -e
WORKDIR="$HOME/ffmpeg_build_x11"
mkdir -p "$WORKDIR"
cd "$WORKDIR"# 1) 安装基础依赖（Debian/Ubuntu / 麒麟 通用）
sudo apt update
sudo apt install -y \autoconf automake build-essential cmake git libtool pkg-config nasm yasm \libx11-dev libxext-dev libxv-dev libxi-dev libxinerama-dev libxrandr-dev \libsdl2-dev libgl1-mesa-dev libpulse-dev libavcodec-dev libavformat-dev \libswscale-dev libv4l-dev libdrm-dev libx264-dev libx265-dev libfreetype6-dev \libwebp-dev libvpx-dev libopus-dev libvorbis-dev libmp3lame-dev libass-dev \libfdk-aac-dev libnuma-dev# 可选：安装一些编码库的源码（略——如果你需要更多 codec，可单独编译）
# 2) 获取 ffmpeg 源码（最新版 stable 分支）
if [ ! -d ffmpeg ]; thengit clone https://git.ffmpeg.org/ffmpeg.git ffmpeg
elsecd ffmpeggit pullcd ..
ficd ffmpeg# 为了保险，清理
make distclean || true# 3) 配置（启用 SDL2、X11、x11grab、opengl 等）
PKG_CONFIG_PATH="/usr/local/lib/pkgconfig:/usr/lib/pkgconfig"

sudo ldconfig# 5) 验证
echo "验证 ffplay 是否支持 -xid ..."
if ffplay -h 2>&1 | grep -q xid; thenecho "OK: ffplay 支持 -xid"
elseecho "警告: ffplay 未显示 -xid（可能编译环境还有缺失依赖）"
fiecho "完成。ffmpeg/ffplay 已安装到 /usr/local/bin"

sudo apt install xdotool x11-utils

屏幕会闪一下。
