RTSP Source 401 after v1.6.0

[emeryao]

Which version are you using?

v1.6.0

Which operating system are you using?

• Linux amd64 Docker

Describe the issue

Hi Team,
Here is my story.

I have 3 different model of TP-Link cameras and added to the mediamtx.yml

at the version of 1.4.x of mediamtx all 3 cameras works perfectly
after upgrade to version 1.5.x one the camera goes down with the log of ERR [path ipc001] [RTSP source] bad status code: 401 (Unauthorized)

and when I update mediamtx to 1.6.0 two of the cameras going down with the 401 message only one camera works for now 😂

I'm pretty sure all the cameras are fine and can be lived with PotPlayer and VLC with the same rtsp url in mediamtx.yml

Describe how to replicate the issue

Did you attach the server logs?

yes

Did you attach a network dump?

no

[aler9]

Hello, this can be certainly fixed but you need to provide a server log with option logLevel: debug, in which the handshake with the cameras (and the resulting 401 status code) is clearly visible. Otherwise the bug cannot be replicated.

it seems that a digest auth was used to authenticate with the camera but the camera seems not supporting in that way @aler9

I have exactly the same issue with cameras from the same brand(TP-Link)

[aler9]

@bobocancan if you want to solve the issue, download and test the nightly release attached in the previous post and let me know if it fixes the problem. If it doesn't attach server logs with logLevel: debug option.

[bobocancan]

Thank you for your reply Alessandro. I am using the docker version, not really sure how I can replace the binary.

@aler9

[aler9]

@emeryao thanks for the feedback, it seems like my patch was unable to solve the issue. Can you post the same log but using v1.4.2 (last working version)? in this way we can check why v1.4.2 was working and my patch was not (BTW i was not able to spot differences between v1.4.2 and my patch). Also check whether credentials are correct.

[emeryao]

@aler9 your patch just works after the camera rebooted with the nightly build 🎉

and it's still a 401 with the version 1.8.1 even if the camera was just rebooted

[aler9]

perfect, i'm merging the patch.
