    hwcontext_vaapi : Make default DRM device selection more helpful

    Iterate over available render devices and pick the first one which looks
    
usable.  Adds an option to specify the name of the kernel driver associated
    
with the desired device, so that it is possible to select a specific type
    
of device in a multiple-device system without knowing the card numbering.
    

    For example : -init_hw_device vaapi :,kernel_driver=amdgpu will select only
    
devices using the "amdgpu" driver (as used with recent AMD graphics cards).
    

    Kernel driver selection requires libdrm to work.

  • streaming a .mov to the browser as it's being written

    1er juillet 2016, par max pleaner

    I’m using the headless and selenium-webdriver gems to create a video :

    # require gems
    
  require 'headless'
    
  require 'selenium-webdriver'
    

    
# start headless
    
  headless = Headless.new
    
  headless.start
    
  headless.video.start_capture
    

    
# use selenium
    
  driver = Selenium::WebDriver.for(:firefox)
    
  driver.navigate.to("http://google.com")
    
  puts driver.title
    

    
# exit headless and save video
    
  headless.video.stop_and_save("test.mov")
    
  headless.destroy

    This produces a test.mov video.

    In this example, I have a finalized .mov file which I could the push to the browser if I wished.

    But I’m hoping there’s a way to stream is as it’s being created.

    If it helps, headless accepts configuration arguments for ffmpeg.

  • avcodec : v4l2_m2m : context : fix raising warning on POLLERR

    avcodec : v4l2_m2m : context : fix raising warning on POLLERR

    During the initialization stage, the codec attempts to get free
    
buffers from the driver before any have been queued (this is to keep
    
the code simple and generic)
    

    When the kernel driver detects this situation, it returns POLLERR in
    
revents and ffmpeg therefore raises a warning.
    

    This commit disables the warning since no buffers were queued to the
    
driver yet.
