我使用FFmpeg从互联网广播流中传输原始PCM数据，然后我会进行一些处理。 在将任何输出发送到stdout之前，FFmpeg缓冲大约10秒，我一直试图让它以更频繁的间隔发送数据，所以我可以用更小的块来处理它。
我查看了各种FFmpeg命令行选项，但找不到会减少使用的内部缓冲的选项。
查看the various format options，我在输入和输出上都尝试了<script type="application/javascript">
$(function(){
$("input[type='radio']").change(function(){
var val = $(this).val();
$(this).parent().find("input[type='radio']").each(function(){
if ($(this).val() < val){
$(this).addClass("belowchecked");
} else {
$(this).removeClass("belowchecked");
}
});
});
});
</script>
