"user_agent not found" when using ffmpeg

[vquie]

Please first read the documentation. Problems affecting the client, e.g. Plex or Emby should be reported there in the forum.

Describe the bug When running the ffmpeg buffer, the stream fails with error "Option user_agent not found." I tried only using ffmpeg, don't know if the others still work.

Option user_agent not found.

Server (please complete the following information):

• OS [e.g. Linux - Ubuntu] Docker Container running on OpenMediaVault (Debian 10.7)
• Arch [e.g. Intel 64 Bit] Intel 64 Bit
• xTeVe Version and Build [to be found in the xTeVe log] 2.1.2 Build: 0121

To Reproduce Steps to reproduce the behavior: Run using ffmpeg buffer with these options -report -hide_banner -loglevel verbose -i [URL] -c copy pipe:1

Expected behavior I'd expect xteve to run the stream. Running the exact same command without the user_agent works in cli. Too bad the user_agent is hard coded in src/buffer.go.

[vquie]

Reviewing the code I found out that leaving the user agent empty leaves the option. The issue is fixed for me.

[mar-mei]

What version of FFmpeg are you using? The user_agent parameter has been around for a few years

I think from 4.3.0 the option was added.

[vquie]

Are you running the docker container? I just removed the images and and started from scratch. Again..... 4.2.1.

[mar-mei]

I don't use docker. Who created the Docker container?

[vquie]

This ist the one I use: https://github.com/alturismo/xteve

The latest version I am able to get is 4.2.4.

[mar-mei]

Does it work with 4.2.4? The user agent is only important if the default user agent is blocked.

[vquie]

Nope, does not work in 4.2.4.

I'm running 4.4.1 and I am also having this problem

**ffmpeg is a independent app. I beleive they have a website for reporting errors, we have no control over it.
