How Pion WebRTC handle ICE role conflict

pion webrtc environment. Version: [email protected] What did you do? we use pion webrtc as client，ice role is contrlolling，remote webrtc as server，ice role is controlling，in this case，an end-to-end not solve the...

livego rtmp模块中readChunk通过bufio Read读取RTMP消息，如果创建RtmpConn时，指定remoteChunkSize大于128，读取上来的消息发现会在128字节后面的129字节插入一个0xc3，导致后面数据错位，解析rtmp包出错

虽然这个库我们做了点修改，但是使用最新的livego源代码，编译后调试，发现跟修改后的一样，可以使用ffmpeg或者微信小程序，进行推流或者拉流，在connect时，该问题必现，下面是修改后的打印日志： 020007636f6e6e656374003ff00000000000000300036170700200036170700008666c61736856657202000d4c4e5820392c302c3132342c320005 746355726c02001972746d703a2f2f3132372e302e302e313a313933352f6170700004667061640100000c6361706162696c697469657300402e00 0000000000000b617564c3696f436f646563730040afce0000000000000b766964656f436f6465637300406f800000000000000d766964656f4675 6e6374696f6e003ff00000000000000000 r.Read return Len: 194 020007636f6e6e656374003ff00000000000000300036170700200036170700008666c61736856657202000d4c4e5820392c302c3132342c320005 746355726c02001972746d703a2f2f3132372e302e302e313a313933352f6170700004667061640100000c6361706162696c697469657300402e00 0000000000000b617564c3696f436f646563730040afce0000000000000b766964656f436f6465637300406f800000000000000d766964656f4675 6e6374696f6e003ff000000000000000002021-09-10 20:09:31.998 Debug rtmp_conn.go:92 1 ChunkStream len: 194，remoteChun kSize：512, from remote:127.0.0.1:65133 local:127.0.0.1:1935: 2021-09-10 20:09:31.998 Debug rtmp_conn.go:109 1 ChunkStream...

微信小程序推流崩溃到func (conn *Conn) handleControlMsg(c *ChunkStream) { if c.TypeID == idSetChunkSize { conn.remoteChunkSize = binary.BigEndian.Uint32(c.Data) } else if c.TypeID == idWindowAckSize { conn.remoteWindowAckSize = binary.BigEndian.Uint32(c.Data) } }
