a -h / --help would indeed be useful, and definitely would have saved me from opening this issue. Another suggestion, maybe include a suggestion to try snowmix -d in the "bailing out" error message? semi-related but different subject: we talked a while back and I was asking where I can find the git repo. You said there's no publicly available git repo. Could I ask why that is and maybe push back on that a little bit and encourage you to make the repo public? I would really like to have access to...

Good to hear. I'll make a note about docuenting it. Perhaps at least with a "-h" flag listing options available.

snowmix -d is working great! problem solved and 0.5.2.1 running fine! thanks again Peter!

My invocation is a bit involved. I'm starting it: in screen, in a loop, in a block of bash, in a function, in the background, in a launch script, in screen, in a systemd unit. I think it's probably the "background" bit that causes it to have no stdin. Here's the relevant code (with added comments so you have some of the method to my madness): start_snowmix() { echo "Starting snowmix..." # This code is running inside a (detached) screen session. # Here we open a new screen 'tab' just for snowmix....

The stderr fd not being 2 was something I saw several years ago when a user was using Docker to deploy Snowmix. In that setup running Snowmix in a Docker container, the selected setup resulted in Snowmix haviing no stdin and stdout and stderr would get fd=0 and fd=1 respectively and opening the first feeds control connection would then get fd=2 creating havoc when the compiler executed a lot of fprintf(stderr,...... to fd=2. I never checked if issue was with the compiler or the issue had something...

I'm running on a pi4 and I'd be happy to try out some of this stuff if that helps. If you've got docs you could send them to me (myusername at myusername dot org) and I'll take a look. I think I remember reading that they did take away a bunch of hardware accelerated stuff with the pi4. Seemed silly to me.
-
Snowmix has code for creating/defining/building on the fly multiple pipelines for hardware encoding, decoding, scaling, rendering and many more things .... and it iis all based on the OpenMAX specs which was fine on Pi 3, but seems sketchy maybe on Pi4 and newer. Maybe it is just the renderer that is sketchy ... I was unsure so the 0.5.2.x releases has not documented the use of Hardware support for the SNowmix program ... although it is there. But iis complicated to use withouth documentation. Documentation...

if you on linux run a program with no stdin, then the stderr socket can get a fd id not being 2 Oooooooooh! This is super interesting! I didn't know this was the case - I've only ever heard of the standard file descriptors you've mentioned - stdin=0, stdout=1, stderr=2. I knew it was possible to have other file descriptors but I didn't know it was possible for these to change. That seems like an unnecessary annoyance. That makes perfect sense. And I can understand why you'd just say "you need to...
-
Not having stdin opened, have you tried running snowmix in daemon mode? snowmix -d I don't remember if that code was thoroughly tested. When in Snowmix calling for the creation of the object VideoMixer, it passes a "daemon mode flag" that may possible prevent snowmix to bail out when it does not have a stdin opened. This flag is enabled with the '-d' paramter. Look also in the code for m_daemon_mode variable. Let me now if iit works. P
-
You are not completely wrong and I am lazy. Here is the thing. There are a lot writing log messages using fprintf(stderr, ...... At a certain time in the past and probably also now for some compilers this will mean the binary is hardcoded to write to a socket with the socket fd = 2. Now if you on linux run a program with no stdin, then the stderr socket can get a fd id not being 2 .... and as you can imagine ... that is not nice for writing data with fprintf to stderr will send data either to an...

That's interesting learning about the setup you ran for the rocket launching stuff. I saw that demo video and was pretty interested/excited - I'm a bit of a space nerd and rockets are cool. yep, my gui-less system has been running great for over 2 years now. The pi pulls in feeds from 8 camera sources and muxes them together into a nice 1080p security camera feed. Then I have some ancillary bash scripts to do things like switch a couple of the virtual feeds between several cameras. The whole thing...
-
I've been slowly investigating the state of GUI toolkits. And as a python guy tk is high on my list of candidates. It's not the prettiest or most modern, but that's a good thing! modern tends to mean "disinterested in backwards compatibility and will make you rewrite your gui every few years" (Hi there gtk!). I'm not really a C/C++ guy so I probably can't help you out with that problem. sorry. But it does seem like it should be doable - have some image control which looks at a particular memory location...

Snowmix doesn't per ay require a windowing system. In the original development setup for Copenhagen Suborbitals rockket launches, was two mixers running 400km away on a launch control ship doing on site primary mixing and control and had no windowing system. Then back at the main studio, I would 4-5 setups concurrently for both speaker booth, control panel and overviewing and one for end mixing (call continuity) before going to CDN (Youtube). The first stage mixing all ran with no windowing system....
-
That sounds like a workable option. This is a new thing in 0.5.2.x right? The same setup works just fine with 0.5.1. It's actually running in a screen session for easy debugging, so it does have stdout and stderr, just maybe not stdin. The invocation isn't straightforward at all. I'll give the ca t | snowmix trick a try when I get back to it. Thanks! Should it be fixed? .... Why? Why? Well... it seems a bit weird to have to pipe something into it to run it as a daemon. Snowmix is definitely the type...
-
I mostly have been using tk/tcl .... a habit from the past. More modern take would be tk+python or maybe a more modern toolkit than tk. Do you know how to get video (or images, video is one image at a time) from a C++ binary like Snowmix into a GUI script (tcl and python + Tk and more) preferably using as little copying as possible? Many many many years ago you could have a frame area inside a Tk/Tcl script (wish) where another process could overlay video (using XVideo), but that model is not only...
-
thanks for confirming!
-
Yeah that's what I thought, I grepped for gnome-terminal and could only find it in the demo script. It's just the default raspberry pi debian, but I've stripped it back and customised a lot. It doesn't run X, or any windowing system. Thanks for the quick responses, I appreciate it! :)
-
Will do. ANonymous is okay, just nicer not doing it anonymously. P
-
Snowmix has some hard coded requirements for access to stdin, stdout and stderr. It was originally introduced when somebody ran Snowmix in a container with no stdin and stderr have the wrong fd number and more. Create a socket and let Snowmix have its stdin from that and remember to send stdout and stderr somewhere meaningful. Otherwise you will have issues. That said, snowmix cannot continue before the socket is opened for writing. So maybe use an unnamed pipe likke this: cat | snowmix ............
-
haha okay. I wasn't sure what the gstreamer support was, so I figured 🤷 enable it! All good, I don't plan on going sleuthing for it yet.

haha okay. Please god don't go with a web based thing. Tk is so much better.

No problem, no rush on any of the stuff I've posted today, I've just reverted back to 0.5.1 for the time being and it's working fine. Are there docs for the new python stuff? I'd like to play with it. I have several ideas for things I'd like to do.
-
Don't enable the snowmixgui. It is currently not a viable path .... intended for a cross platform GTK3 UI C++ based interface ..... but currently it is not being implemented. Looking into a web based interface instead in addition to Tk based scripts (python/ttcl etc.). Web based interfaces require node.js and I still don't know how to transport video over to a browser tab with zero copying (shm). P
-
While the code in Snowmix is there, that specific release 0.5.2.1 does not explain what gstreamer does in the Snowmix code or how to use it, so unless you go Sherlock Holmes, you probably should not include it in the compilation. That applies for the dev headers for GStreamer. For GStreamer for the scripts, they don't need the dev version. But the GStreamer code in Snowmix, can make it super easy to connect OBS as source for a video/audio feed directly into Snowmix using RTMP. Also works with some...

Hi Antisol. gnome-terminal is only used by the sctipt placed in scripts/demo and installed as an available script with the name snowmix-demo. I got tired in the demo script of finding out how a specific terminal can run a script (gnome-terminal uses -c and some uses -e and some uses something else. I know I should have fixed it, Installing gnome-terminal when possible was a quickfix. But if you don't run snowmix-demo, you don't need gnome-terminal. ptyxis works too. Don't remember if lxterminal uses...

Sorry to spam the thread but I have another note: I also had to install the package libgstreamer-plugins-base1.0-dev on debian. I'm building with gstreamer support so I expect that's why.
-
just another note, I'm actually not running a windowing system on the machine in question, so even xterm seems like an unnecessary requirement. Though I'm not opposed to installing it like I am with gnome-terminal. I couldn't find anywhere in the code where gnome-terminal is referenced except demo scripts, so I removed gnome-terminal from the list of required packages in bootstrap-debian and the size of packages I need to install went from over 50MB down to 10MB.

Hi Peter, I've finally gotten around to trying to compile the new version. It's telling me that gnome-terminal is a required package? why does it need gnome-terminal? Why gnome-terminal and not something more universal and lightweight like xterm? I'm not using gnome and I expect installing gnome-terminal will also pull in a bunch of gnome dependencies that I do not want.

At relase time for Snowmix 0.5.2.1 (ultimo 2025), installing required libraries and packages for for compiling Snowmix on Linux Mint Cinnamon 22.2 result in package conflict for some packages. The Linux Mint Community has fixed the issue and Snowmix can now be compiled on Linux Mint Cinnamon 22.2. And Snowmix still compiles fine on Linux Mint Cinnamon 21 and 22.3.

Welcome back Peter, I honestly thought you'd were done with Snowmix and had found a better project to work on? Unfortanely, I've continued to try and try again in developing and learning code old C for my DATV repeater project and have been year in to understanding the GStreamer Framework. I have even written my own GStreamer plugins to do the transitioning between video and audio feeds using SIMD which has a been a long and rewarding learning cure. Anyway. Good to have Snowmix 0.5.2 out and look...

Thanks Peter It was a while ago but I did try pretty hard to get in touch with you. I remember I sent you a message on linkedin. If you're replying on here then I suppose that's enough. I don't have the details for the improvements I made at hand right now, and I'll need to take a look at the new version and work up a patch. I'll just open a new ticket on here. Thanks

Hi Antisol. The project has no public available Git repository. For now you can post here in the "General Discussion" or you can sen DM to my account here. If you have anything more substantial, DM me and I can send you my email. That would usually require I know who I am sending to. I am not flashing my identity but also not hiding it and with my name, I am easy to find on the Internet. Bug reports are more than welcome and fixes too.Suggestions for features are welcome too. Best regards Peter ...

Awesome! i'll be very interested to check out the new version and features. But you didn't answer one of my questions about how to get access to a repo with e.g git history? I don't see any way to access such a thing. How should I contribute fixes to snowmix?

Hi On the outlook for somebody with macOS newer than Monterey for testing Snowmix. Please contact me if you have an Intel based Mac and can and would like to test Snowmix. M1, M2etc all based on ARM is to be tested later. Let meknow if you have the hardware and can and would like to test. Best regards Peter Maersk-Moller

Hi, I abbadoned SNOWMIX long ago and looked at using GStreamer framework for my project. The core code in snowmix is brilliant. I'd suspect somebody would take what Peter had and break it up into a API. The methods with scripting is convoluted and could much simpler.

Hey guys, I was using snowmix for a while however, as I become familiar with Gstreamer, I ended up writing my own AV mixer and ditching snowmix. I had a lot of scripting to setup the ini file and then use the socket for communications once snowmix was up and going to do stuff. I never liked how snowmix used a file descriptors for audio! The shared memory used for video would have been a far easier approach. Anyway, I hope Peter is ok?? On Thu, 4 Jul 2024 at 4:15 AM, C J egftechman@users.sourceforge.net...

Is this project dead?

Hello, Thanks for snowmix. It's really great! I'm using it to mix realtime video from multiple security cameras onto a monitor.

Hello Peter, Do you have any examples in how to implement a horizontal bar graph? I'd like to place an overlay frame with transparent cut-outs to insert some solid moving bar from left to right. Use TCL or python, Python preferred. 3 bars with additional text fields which can be updated dynamically while the overlay is visible and then fade in and out the complete overlay, bars and text on the top stack? Here is example attached. I'm sure it is possible with overlays and shapes possibly. Rob

still dry swimming :-) loading the images would be ~~~ command create loadmyani.tcl for {set i 0} {$i < 251} {incr i} { set loadnr [format "1%03d" $i] set fnam [format "ccla-%04d" $i] set filename ${fnam}.png snowmix parse image load $loadnr path/$filename } command end ~~~ and run with tcl exec loadmyani.tcl Maybe better would be to load one image each x frames from snowmix instead of loading them all at once. Yes, i'd look into the manual (RTFM) and see howto use loop or loop 250, postone with...

OK, i have to take care if i'm logged in :-) To show the image i need to count up the image id i'm assuming the following will not work, as the tcl for-loop might be not executed as one step per frame: command create myani tcl eval for {set i 0} {$i < 251} {incr i} {set loadnr [format "1%03d" $i] tcl eval snowmix image place 1000 $loadnr 0 0 loop 250 command end mabe something like this will work command create myanipreset tcl eval {set i 0 } command end command create myanishow tcl eval {incr i}...

Hello, Thanks for response, indexed images sounds charming. I will try. Replacing the greenscreen with transparent in imagemagic is easy. adjust fuzz to get rid of the (anti?)-aliasing blurr around Text and objects - not to much then you lose your content for f in ../images.greenscreen/*.png; do i=$(basename -- $f);convert $f -fuzz 40% -transparent \#00fd00 $i; done i'll swim dry now: I think i should create 2 snowmix commands, one for loading the images (if i want in the middle of our show a different...

There are at least two ways to do the animation with logos. First way is to load is logo as image with transparent background, and then create a macro that handles all the scaling, placing, movement and turn them off in the end one by one. Second way is convert your animation into images and load them as an indexed image and have a macro enabling, forwarding the index pointer and and then just overlay the indexed image. Now this solution has a smaller problem because indexed images is not supproted...

Hi Peter, I just use the stack command to switch between the cams, nothing else. (i send "stack 4" with netcat to snowmix to switch the output to cam 4) We have 5 cams in FullHD we switch thrugh as need, some Text's and some images that i am changing/placing with commands via netcat to snowmix. Here i put a sample and a greenscreen video from what i like to do (the blurred background is not need to implement, it is just to see the animation better) https://drive.google.com/drive/folders/1GItdgjwBQhb-MvHGATzQfPXyipcNrW0s?usp=sharing...
