我已经使用命令流式传输到 twitch.tv：
ffmpeg -stream_loop -1 -i 9stream.wav
-f dshow -i audio="mic"
-f dshow -i audio="realTek"
-filter_complex "[0:a]volume=2[a0];[1:a]volume=1.5[a1];[2:a]volume=1.5[a2];[a0][a1][a2]amix=inputs=3"
-f dshow -i video="USB2.0 PC CAMERA"
-ac 1 -ar 11025 -acodec libmp3lame -c:v libx264 -b:v 100k -f flv -s 80x120
rtmp://live.twitch.tv/app/live_streamingKey
这是我用来在线流式传输的最高级命令。
（我这里不知道怎么输入所以我输入了双输入）
9stream.wav 作为背景音乐循环播放
麦克风已添加
名为realTek的stereoMix是播放系统声音
音量已调整，所有声音混合为一个流
添加了相机视图
THEN 网络流量减少，只发送一个频率最低的 11025 频道
mp3 编码器和 libx264 产生的可能数据大小用于编码 png 文件中的视频。
效果很好，所以我决定制作最终版本
（这个适用于所有声音（背景音乐、麦克风、系统声音）和相机）
最终版本是关于添加屏幕视图和徽标。
我成功地使用命令将所有内容写入光盘：
ffmpeg
-stream_loop -1 -i 9stream.wav
-f dshow -i audio="mic"
-f dshow -i audio="stereoMixRealtek"
-i camera.png
-f gdigrab -framerate 1 -i desktop
-f dshow -framerate 15 -i video="USB2.0 PC CAMERA"
-filter_complex "[0:a]volume=2[a0];[1:a]volume=1.5[a1];[2:a]volume=1.5[a2];
[a0][a1][a2]amix=inputs=3[aMix];
[4:v]scale=200:-1[v4];[5:v]scale=50:-1[v5];
[v4][v5]overlay=(W-w)-5:(H-h)-5[vScreenCam];
[vScreenCam][3:v]overlay=5:5[v]"
-map "[v]" -map "[aMix]" -ac 1 -ar 11025 -c:a libmp3lame -r 1 -c:v libx264 output.mkv
那个
背景音乐
麦克风
系统声音
标志图片
屏幕视图
相机
调节音量
混合声音
缩小屏幕视图和相机视图的大小
将缩小的相机视图覆盖在缩小的屏幕视图上
添加标志
选择最终视图，最终混合声音，
将数据大小减少到一个通道，降低采样频率，
选择 mp3 编解码器以减少最终数据大小，
选择每秒一帧的最小帧率以减少数据大小
为视频选择 libx264 编解码器。
然后我尝试使用最终命令进行网络流传输，稍作修改：
ffmpeg
-stream_loop -1 -i 9stream.wav
-f dshow -i audio="mic"
-f dshow -i audio="stereo mix"
-i camera.png
-f gdigrab -framerate 1 -i desktop
-f dshow -framerate 15 -i video="USB2.0 PC CAMERA"
-filter_complex "[0:a]volume=2[a0];[1:a]volume=1.5[a1];[2:a]volume=1.5[a2];
[a0][a1][a2]amix=inputs=3[aMix];
[4:v]scale=200:-1[v4];[5:v]scale=50:-1[v5];
[v4][v5]overlay=(W-w)-5:(H-h)-5[vScreenCam];[vScreenCam][3:v]overlay=5:5[v]"
-map "[v]" -map "[aMix]"
-ac 1 -ar 11025 -c:a libmp3lame -r 1 -c:v libx264 -b:v 100k -b:a 10k -f flv rtmp://live.twitch.tv/app/live_streamingKey
我添加了参数 -b:v 100k 以减少视频流量 -b:a 10k 以减少声流 -f flv 对 twitch.tv 有好处，否则它不会接受流
但是 ffmpeg 总是停止发送带有如下消息的数据：

流 0 有问题，所以它是混合声音流，但早些时候混合没问题
并通过互联网发送混音，但在我添加屏幕视图并对其进行缩放后无法正常工作。
什么问题？
如何解决？
因为我能够这样做以流式传输到光盘，所以我假设
计算机处理能力足够了。由于我能够通过互联网传输混合声音，我
假设这里没有问题。所以问题一定是发送
屏幕视图。但是我将帧速率设为每秒 1 并缩小其分辨率。我压缩了
听起来尽可能多。我添加了 -b:a 和 -b:v 命令以减少网络流量。
我还能做些什么来修复它？
