Sdcb.FFmpeg issues

求教怎么初始化？

3

VS2022已安装 Sdcb.FFmpeg 6.1.0.1、Sdcb.FFmpeg.runtime.windows-x64 6.1.1. FormatContext inFc = FormatContext.OpenInputUrl("rtsp://admin:@192.168.58.89:554/channel=1_stream=0"); inFc.LoadStreamInfo(); MediaStream inVideoStream = inFc.GetVideoStream(); 运行时报错System.DllNotFoundException:“无法加载 DLL“avformat-60”: 找不到指定的模块。 (异常来自 HRESULT:0x8007007E)。” 使用大佬库时要先初始化吗？查了下DEBUG\DLL\X64\下有avformat-60

请问代码怎样实现摄像头推流的操作?

我想用代码执行如下推流命令, 代码需要怎么写? .\ffmpeg -i "rtsp://admin:@192.168.58.89:554/channel=1_stream=0" -pix_fmt yuv420p -vcodec libx264 -an -f flv "rtmp://192.168.99.100:1935/live/stream0" 看完例子还是不太会写, 是一定要从inputContext每帧读取再写到outputContext吗? FFmpegLogger.LogWriter = (level, msg) => Debug.WriteLine(msg); using FormatContext inFc = FormatContext.OpenInputUrl("rtsp://admin:@192.168.58.89:554/channel=1_stream=0"); inFc.LoadStreamInfo(); MediaStream...

能给一个纯音频的转码例子吗？尝试了一下，总是报错，没有发现网上有类似音频的例子，代码里给的几个例子都有视频流在里面。感谢周老板

[FFmpeg error -2]: No such file or directory 用下面的代码列出USB摄像头，报错 var dict = new MediaDictionary(); dict.Set("list_devices", "true", 0); using FormatContext inFc = FormatContext.OpenInputUrl("video=dummy", InputFormat.FindByShortName("dshow"), dict); inFc.LoadStreamInfo();

Fields for 'Unknown Unit Names' will not properly set ByReference

Should just probably add after this line https://github.com/sdcb/Sdcb.FFmpeg/blob/release/7.0/src/Sdcb.FFmpeg.AutoGen/Processors/StructureProcessor.cs#L198 ```csharp ByReference = !arrayType.QualifiedType.Qualifiers.IsConst ``` Has been noticed with av_image_fill_pointers for example
