Hello,

I've found an issue when I run multiple versions of the process at once:

As far as I can tell, one instance will run all day without a problem, but once I add another simultaneous process it craps out after a few minutes.

I'll run in verbose mode and find if that yields more information.

Hi.
I am very new in software developers world, and I have never used golang before.
So, please excuse me. Could you, please, help me resolve this issue?

Hi Guys,
I installed the plugin on octoprint 1.4.x,
can see it in the plugin manager but not configure it.
If that still works, I would like to use it in combination with videostream that I don't have to change the tempalte manually.
Tanks

Hello,

I've just tried your project. Looking exactly for something like this.

Code compiles and starts just fine. Used cmd line
./videostreamer -port 9100 -input rtsp://videostreamer:[email protected]:554/cam/realmonitor?channel=1&subtype=1 -host 192.168.0.20 -verbose -fcgi=false

It outputs:

2018/07/23 21:29:46 encoder: Waiting for clients...

Opening the index.html sample page (with corrected video url) it shows nothing.

Tried the remux-example to save the video to file and that works just fine.

Any tips on how to troubleshoot?

Erik

Hello,

installing on debian stretch is not possible, because:

go get github.com/horgh/videostreamer
# github.com/horgh/videostreamer
work/src/github.com/horgh/videostreamer/videostreamer.go:346:14: could not determine kind of name for C.av_packet_clone
work/src/github.com/horgh/videostreamer/videostreamer.go:265:4: could not determine kind of name for C.av_packet_free

Any idea how to solve this issue?

Hello,

First, sorry for my bad english write..

I followed the install description on Linux without problems, however I have problems on Windows (10), and it is impossible for me to build the program on Win10.
The main problem, seem the only problem, is related to access to the FFmpeg library.

• I discover "Go" and only have a few days of discovery
• I do not control too much the options of building "C" program

-> i use MinGW 730_x64 (which I use without worries for other constructions with "Go", like for OpenCV)
-> The "ffmpeg" library come from the "pack" developer of the official website, and its installed in a "libs" folder
(!) there is no ".pc" file in this pack, useful for "pkg_config"
So...
I added the program "pkg_config" (and its dependencies) in my MinGW folder, it is taken into account during the construction.
I get ".pc" files from my linux (same library version) and "modified", by hand, the paths to correspond to the "libs" folder of my windows
I indicated in the variable "PKG_CONFIG_PATH" the folder of the files " .pc" (and check that they are taken into account)
Without success, during the build, I always have an error to find the ffmpeg library.

So I tried to indicate the path of the libraries via the set variable CGO_CPPFLAGS ("-I") and CGO_LDFLAGS ("-L"), again without success.

I "resolve" somme error from "*.h" acces file (ffmpeg library), it's very bad method, i know ;), but at the end it was now some "linked" error i get...(sic)

My lack of knowledge "Go" and build options, prevents me from going further, however I remain convinced that I do not miss much :)

• Is it possible not to use "pkg_config" and to indicate in another way where to find the libraries?
• Is there an option, variable to fill in to "force" their file?
• Is there a "new" installation method (for windows)

Thank you very much in advance for all "tracks" to succeed, finally, in compiling the "Go" program

Hi,

That's a great project, thanks for putting this together!
I see you provide a Dockerfile, it would be great to propose both a dockerimage to pull as well as a docker-compose to ease the setup of the project.

I can contribute and will open a related PR soon.

Hi,

Excuse me!!

I don't know if is by the client (

How can I improve to reduce lag?

Maybe

• client and server using Websockets?

Thank you so much!!

Maybe you should look towards multi-camera streaming? It's very easy to implement

Hello! Thx for great app. Can you help me? I'm start streamer with command:

I'm not getting any audio with my stream. Is that to be expected?

Thank you so much.

For more convenient use, it may be worth revising the approach to configuring the application through config files. I can help you with that

Hello, and thank you for writing this excellent application! I've been trying to integrate this into a video wall application, but after about 25s, the software closes the input.

I'm running this on Ubuntu 16.04 with FFMPEG installed from this PPA.

The client is Google Chrome (63.0.3239.132) with the mp4 URL opened directly.

Here is the output from the daemon:

Hello,
Compile on ubuntu produces error:

could not determine kind of name for C.av_packet_clone
could not determine kind of name for C.av_packet_free
could not determine kind of name for C.av_packet_unref

I install packages: libavcodec-dev, libavutil-dev, libavformat-dev

Any idea what could be the issue?
Thanks!

I got it running well enough. I'm using it to monitor my 3d printer using octoprint. I had to use a plugin to get octoprint to be able to read the feed but that's working now. The problem I'm running into is that the stream seem to stop without warning, though maybe the lack of warning is because I have videostreamer set to run as a service? Is there some sort of timeout in the code that I'm not seeing?
