Audio 使用FFMPEG将16通道音频输入源拆分为4个独立的4通道音频源，用于流媒体
我希望有人能帮忙 我目前正在尝试将一个16通道Dante音频源从一台单独的机器分割成4个不同的音频流，然后通过RTMP发送到Wowza进行MPEG-DASH编码，目前我正在尝试将它们分割成文件，稍后我将添加RTMP流 目前我遇到的最大问题是FFMPEG从输入字符串返回这个错误Audio 使用FFMPEG将16通道音频输入源拆分为4个独立的4通道音频源，用于流媒体,audio,ffmpeg,streaming,audio-streaming,rtmp,Audio,Ffmpeg,Streaming,Audio Streaming,Rtmp,我希望有人能帮忙 我目前正在尝试将一个16通道Dante音频源从一台单独的机器分割成4个不同的音频流，然后通过RTMP发送到Wowza进行MPEG-DASH编码，目前我正在尝试将它们分割成文件，稍后我将添加RTMP流 目前我遇到的最大问题是FFMPEG从输入字符串返回这个错误 Filter channelsplit:WR has an unconnected output ffmpeg -f dshow -i audio="Dante Via Receive (Dante Via)" -fil

- 尝试添加
dshow输入选项-channels 16 - 过滤器输出标签不能在
中组合，因此请使用过滤器进行所有混合，并为每个-map
提供单个标签-map - 仅将通道作为单个流输出，并且它不会将多个通道混合到单个流中，因此使用
- 我没有dshow，所以我无法测试这个
