Hi!
**1. We are using VOXL2 mini.
2. VOXL2 mini version is SDK 1.4.3.
3. Problem with voxl-streamer when using uvc camera h.265 encoder**
1) When using "h.265" in voxl-streamer.conf, voxl-streamer service **dies.**
There is no problem at all in h.264.
The player we use is VLC and potplayer.
2) The config settings are as follows.
**[voxl-uvc-server.conf]**
-Resolution = 640x480
-Frame = 20
**[voxl-streamer.conf]**
Bandwidth = 500000
encoder = "h.265"

3) The error code is as follows.

**4) Please tell me the solution.**

JS, Kim

Hello @Jskim,

the parameter in `voxl-streamer.conf` should be `h265`, not `h.265`, i think behavior is undefined otherwise. The two options are `h264` and `h265`. There should probably be a check for this.. I will add...

Please try `h265` and let me know if that fixes the issue.

Alex

Hi Ales,

I think the above statement is wrong. Sorry. I inputted it as h265.
![voxl-streamer.conf.jpg](https://forum.modalai.com/assets/uploads/files/1744955414806-voxl-streamer.conf.jpg) 

There is no problem with h264, but voxl-streamer dies when I use only h265.

Thanks,

JS, Kim

@Jskim , can you please run `voxl-streamer` in foreground and paste the whole output (the full error description is cut off by the screen shot). 

Also please check which version of voxl-streamer you are using (`voxl-version | grep voxl-streamer`)

Thanks!

@Alex-Kushleyev 

Currently alive, but have to wait until the streamer dies. Sometimes he dies.

@Jskim 
[The phenomenon is as follows]
Video Player restart
Video works normally (about 3 minutes)
Streamer is not dead, but the video is frozen.
Looking at the top command contents, Streamer CPU usage is 2.3%.

It stops for 5 minutes and then works normally again (about 1 minute).

It stops again. (CPU usage 1.9%)
Normal operation after 5 minutes
Video freezes after 1 minute (CPU usage 2.3%)

@Jskim 
Finally, I tried a test.
I tried changing the video player and the Streamer died immediately.
The conclusion is that the Streamer died even when it was in the foreground.
