    Une file d’attente stockée dans la base de donnée
    Lors de son installation, SPIPmotion crée une nouvelle table dans la base de donnée intitulée spip_spipmotion_attentes.

  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

    vpxenc : add deterministic output option

  • Appium iOS screen recording in parallel runs result in overlapping videos

    29 juillet 2020, par Shiori Bermudo

    My code is in Python. I'm using appium's built in function driver.start_screen_recording() driver.stop_screen_recording().

    


    I run two tests (A and B) on different devices (A and B respectively), different appium servers (ports) and different wdalocalports. The tests are running on a schedule in Jenkins.

    


    Each test look something like this :

    


    self.driver = webdriver.Remote("http://localhost:portA/B")
# Part1
self.driver.start_screen_recording()
# do something ...
vbytes = self.driver.stop_screen_recording()
self.save_movie(vbytes, Part1fileName)
# Part2
self.driver.start_screen_recording()
# do something ...
vbytes = self.driver.stop_screen_recording()
self.save_movie(vbytes, Part2fileName)
# do something until test is over...
self.driver.quit()


    


    When Test B starts while Test A is running, the video output of B is showing the screen of Test A. The saved filenames are correct. TestA.mp4 is correct but TestB.mp4 shows the screen of Device A.

    


  • ffmpeg - overlay a video with rounded corners

    4 novembre 2019, par asi

    I am successfully using overlaying a scaled (smaller) video on top of a larger one but am struggling to understand how could I give the small video a rounded corners mask.

    Edit

    thanks to @loogan comment I’ve managed to get a working command that created applies a circular mask :

    ffmpeg 
    
    -i main.mp4 
    
    -i vignette.mp4 
    
    -filter_complex 
    
      [1:v]scale=300:-1[scaled];
    
      [scaled]split [scaled0][scaled11]; 
    
      [scaled0]trim=end_frame=1,geq='st(3,pow(X-(W/2),2)+pow(Y-(H/2),2));if(lte(ld(3),780*780),255,0)':3:3,loop=-1:1,setpts=N/FRAME_RATE/TB[mask];
    
    [scaled1][mask]alphamerge[cutout];
    
    [0][cutout]overlay=x=W-w:y=0[v];
    
    -map [v] 
    
    -map [a]  
    
    output.mp4

    but how to get from a circle to a rounded rect still eludes me. cant quite get what are the params that geq expects and the math to generate them.

    assuming that the video that needs masking is 200 * 300 and the corners should have a 5px radius, is there a geq command that can create this mask ? maybe en ellipse ?

    or maybe a better way would be to use a pre-made png as a mask ?

    any insights welcome
