Hi, I encountered some issues while trying the streamingtest.html demo page of the streaming plugin: - When audio=false, Firefox browser fails to play and displays “no videotransceiver with mid v”. Chrome and Edge can play successfully. - When audio=true, Firefox/Chrome/Edge all fail to play. In Janus logs, the following message is displayed: > (janus:3287717): libnice-stun-DEBUG: 13:56:07.049: STUN error message received (code: 401) > (janus:3287717): libnice-stun-DEBUG: 13:56:07.049: STUN demux: OK! > (janus:3287717): libnice-stun-DEBUG: 13:56:07.049: STUN unknown: 0 mandatory attribute(s)! > (janus:3287717): libnice-stun-DEBUG: 13:56:07.049: **STUN error message received (code: 401)** > (janus:3287717): libnice-DEBUG: 13:56:07.049: Agent 0x7f6b4400b000 : stun\_bind\_process/conncheck for 0x7f6b38009820: controlling,res=error,stun#=0. > (janus:3287717): libnice-DEBUG: 13:56:07.049: Agent 0x7f6b4400b000 : pair 0x7f6b38009820 state FAILED (candidate\_check\_pair\_fail) > (janus:3287717): libnice-DEBUG: 13:56:07.050: agent\_recv\_message\_unlocked: Valid STUN packet received. > (janus:3287717): libnice-DEBUG: 13:56:07.068: Agent 0x7f6b4400b000 : stream 1: timer tick #151: 0 frozen, 0 in-progress, 0 waiting, 0 succeeded, 0 discovered, 0 nominated, 0 waiting-for-nom, 0 valid. > (janus:3287717): libnice-DEBUG: 13:56:07.068: Agent 0x7f6b4400b000 : waiting 1000 msecs before checking for failed components. > Got an H264 NAL 5 > [rtsp-test] Sending SPS/PPS (seq=3175, ts=1389600) > [ERR] [ice.c:janus\_ice\_check\_failed:2066] [16579125475228] ICE failed for component 1 in stream 1… > [16579125475228] Hanging up PeerConnection because of a ICE failed In previous test(failed), I capturing packets with Wireshark, the following content is observed(192.168.1.72 is my local computer which running browser, 192.168.1.117 is the machine that Janus gateway runs on): > No. Time Source src-port Destination dest-port Protocol Length Info > 853 19.576571 192.168.1.72 49311 192.168.1.117 39551 STUN 138 Binding Request user: TuVy:Zggk > 854 19.576608 192.168.1.72 49311 159.75.250.190 2001 STUN 62 Binding Request > 859 19.577648 240e:3b3:30cf:3810:4c2f:e851:25ce:bbd1 49312 2402:4e00:101a:f801:0:9a5f:c749:1b8c 2001 STUN 82 Binding Request > 903 19.581806 192.168.1.117 39551 192.168.1.72 49311 STUN 122 Binding Success Response XOR-MAPPED-ADDRESS: 192.168.1.72:49311 user: TuVy:Zggk > 977 19.586826 159.75.250.190 2001 192.168.1.72 49311 STUN 174 Binding Success Response XOR-MAPPED-ADDRESS: ::ffff:113.89.233.58:49311 MAPPED-ADDRESS: ::ffff:113.89.233.58:49311 RESPONSE-ORIGIN: :::2001 > 979 19.587636 2402:4e00:101a:f801:0:9a5f:c749:1b8c 2001 240e:3b3:30cf:3810:4c2f:e851:25ce:bbd1 49312 STUN 194 Binding Success Response XOR-MAPPED-ADDRESS: 240e:3b0:302c:9cbc:b19b:5c46:8fe1:9828:49312 MAPPED-ADDRESS: 240e:3b0:302c:9cbc:b19b:5c46:8fe1:9828:49312 RESPONSE-ORIGIN: :::2001 > 1003 19.604195 192.168.1.117 39551 192.168.1.72 49311 STUN 134 Binding Request user: IF+5:TuVy > 1007 19.604613 192.168.1.72 49311 192.168.1.117 39551 STUN 90 **Binding Error Response error-code: 401 (Unauthenticated) Unauthorized** > 1017 19.631126 192.168.1.72 49311 192.168.1.117 39551 STUN 138 Binding Request user: TuVy:Zggk > 1030 19.633219 192.168.1.117 39551 192.168.1.72 49311 STUN 122 Binding Success Response XOR-MAPPED-ADDRESS: 192.168.1.72:49311 user: TuVy:Zggk > 1040 19.644204 192.168.1.117 39551 192.168.1.72 49311 STUN 134 Binding Request user: IF+5:TuVy > 1044 19.644606 192.168.1.72 49311 192.168.1.117 39551 STUN 90 Binding Error Response error-code: 401 (Unauthenticated) Unauthorized > 1057 19.693905 192.168.1.72 49311 192.168.1.117 39551 STUN 138 Binding Request user: TuVy:Zggk > 1072 19.696122 192.168.1.117 39551 192.168.1.72 49311 STUN 122 Binding Success Response XOR-MAPPED-ADDRESS: 192.168.1.72:49311 user: TuVy:Zggk > 1084 19.705606 192.168.1.117 39551 192.168.1.72 49311 STUN 134 Binding Request user: IF+5:TuVy > 1088 19.706066 192.168.1.72 49311 192.168.1.117 39551 STUN 90 Binding Error Response error-code: 401 (Unauthenticated) Unauthorized I noticed that the problem seems the browser return a 401 error in response to janus’s binding request, but what reason behind this? Hope to receive your assistance. My configuration: - I am using ffmpeg for pushing the rtsp stream(audio: pcmu/8000/2, video: h264/90000). - Janus is installed on the local network at 192.168.1.117. One of the configuration items in janus.plugin.streaming.jcfg is as follows: ```auto rtsp-test: { type = "rtsp" id = 99 description = "RTSP Test" audio = true video = true url = "rtsp://192.168.1.117:8554/mystream" } ```
