  • OpenFaas. Write python function with FFmpeg using

    11 août 2021, par Валентин Никин

    I need to write OpenFaas function which can accept binary file as parameter. This function will extract some data from that binary file. Based on that data function will generate ffmpeg command. And finally function must be call ffmpeg to process generated command and return file as output.

    


    Function language must be python, because I need to use some python modules to process input binary file.

    


    The main questions :

    


      

    1. Can I accept binary a file as function parameter (in python function) ?

      2. 


    2. Can I call ffmpeg from python function, and return binary file as output ?

      3. 


    


    I have already met with alexellis official example (https://github.com/alexellis/openfaas-streaming-templates) but that example used bash language.

    


    I have one idea, but I don't know is it correct.
Maybe I can use example with bash, to accept binary file as parameter, then I call python script, after that I call ffmpeg, and return file as output as described in the example.
But I need some python modules available with pip. So, I don't know how I can got this.

    


    I'm newest in OpenFaas, so any idea would be appriciated

    


  • FFMPEG Command failing in script

    12 octobre 2016, par Jerry

    I have a nodejs script/server that is running an ffmpeg screenshot command every 30 seconds. I have a list of files that I want to screenshot every loop, and I simply feed it into the command like so :

    exec("ffmpeg -ss 00:00:01 -i /secondary/videos/"+file+" -y -vframes 1 -q:v 2 /secondary/snapshots/"+camera_id+".jpg && scp /secondary/snapshots/"+camera_id+".jpg user@host:/path/to/site/img/snapshots/ && rm /secondary/snapshots/"+camera_id+".jpg", function(err,stdo,stde){
    
});

    file is an absolute path to an flv file such as "vid123.flv". camera_id is an id from a local database of my home security cameras, so they’re numbered 1-100. An example command I’m trying to run is this :

    exec("ffmpeg -ss 00:00:01 -i /secondary/videos/vid123.flv -y -vframes 1 -q:v 2 /secondary/snapshots/1.jpg && scp /secondary/snapshots/1.jpg user@host:/path/to/site/img/snapshots/ && rm /secondary/snapshots/1.jpg", function(err,stdo,stde){
    
});

    However, when I run this in node, I get an ffmpeg error saying "/secondary/videos/vid123.flv : No such file or directory". If I run the same command in the terminal, I get the correct/expected results - a snapshot/frame at 00:00:01 is taken, saved to a jpg in /secondary/snapshots/, scp’d to another server, and removed from the /secondary/snapshots directory.

    I’m raking my brain right now and I can’t figure out why the different results for the same command.

    Any help/tips are appreciated !

  • publish chromium rendered view to ffmpeg/libav

    21 février 2014, par user3337537

    I would like to publish chromium rendered view to ffmpeg/libav stream instead of showing it on the operating window system.
    Also plugins like flash should be included in the stream. I don't know much about chromium rendering yet.

    I know there are command like "ffmpeg -f x11grab -s 1280x720" ... But i would like to do this right from chrome to publish mutliple tabs at the same time.

    How would you estimate the development effort for that ?
