  28 avril 2021, par Didit Setiawan

  i try to running testcase using selenium python and want to record video on every testacases, but when i try the output is always corrupted. FFMPEG process are running, no error appear on the output line. I attach my code, Please anyone help me is there anything i need to add or remove

  


  here's the first file, for recorder :

  


  import subprocess
from subprocess import Popen
from subprocess import call


class recorderMethod():
    videoRecording = None

    @staticmethod
    def recorder_start(res,name):
        rec_lib          = 'ffmpeg -y -rtbufsize 2000M -f dshow  -i video="screen-capture-recorder" -s '
        resolution       = res
        buffer           = ' -b:v 512k -r 20 -vcodec libx264 '
        filename         = name
        extension        = '.mp4'
        complete_command = rec_lib+resolution+buffer+filename+extension

        recorderMethod.videoRecording = Popen(str(complete_command))

    @staticmethod
    def recorder_stop():
        if recorderMethod.videoRecording.poll() is None:
            call('taskkill /F /T /PID ' + str(recorderMethod.videoRecording.pid))


  


  here's the main test file for record the video

  


  import unittest
import recorder_main
from selenium import webdriver
from time import sleep

class recordingTest(unittest.TestCase):
    #init test
    browser         = webdriver.Chrome()
    baseurl         = 'http://www.facebook.com/'
    record          = recorder_main.recorderMethod
    
    #setup
    def setUp(self):
        #declare to use browser
        self.driver = recordingTest.browser
        #make variable for easy access
        driver = self.driver
        #maximize Firefox
        driver.maximize_window()
        #go to maukerja
        driver.get(recordingTest.baseurl)

    #test001
    def test_001_record(self):
        #start recording
        recordingTest.record.recorder_start('1920x1080','Test_Sleep')
        sleep(10)
        #stop_recording
        recordingTest.record.recorder_stop()


    #teardown
    def test_999_ShutDownTest(self):
        self.driver.close()
        
if __name__ == '__main__':
    unittest.main(exit=False)


  


• hwcontext_vaapi : Make default DRM device selection more helpful

  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.
