JT/T 1078 - Troubleshooting help needed

SwayDev 3 hours ago

Traccar version: 6.14.2

Everything seems to be as expected, however the stream/video does not work.

  • Port 5015, Tracking & Commands are working
  • Traccar is receiving stream data from the dashcam (port 5263)
  • Stream data seems to match protocol document
  • Browser console shows .ts files and stream link to have content and no errors.

Am I doing something wrong?

Screenshots below
Stream starts, log displays stream data being received, Data seems to match the protocol documents for JT/T 1078.

What codec are you using?

SwayDev 3 hours ago

Payload type is 99.

I am not sure whether the device is sending H.264 or H.265.

By codec I am assuming you are referring to the data device is sending right? Most likely H.264, I have asked the manufacturer for confirmation as well.

Looks like the device is sending H.265 / HEVC. That is the problem. You need to configure it to use H.264. There are some known issues with H.265.

Thank you, will check if I can configure it to use H.264, will update here once tested.

Is there a limitation on client rights to limit video viewing time? Because with unlimited video viewing, all the traffic allocated for receiving coordinates runs out very quickly.

No limits currently.

@naeim I think that should be controlled on the SIM/provider level.
