Attaching video URL after every test run in pytest html report

After every test run i am getting the video URL but when the report gets generated the URL is only shown for the 2nd test case which is of the 1st one and for 1st one it doesn't show anything.
Note: the video URLs are generated correctly for each test cases it just that i am not able to properly attach the link to each test case in the report.
can someone help me with this please:

Below is my code snippet:
@pytest.fixture(scope="function")
def test_obj(browser, browser_version, platform, os_version, request):
global driver
driver_fact = DriverFactory()
test_name = os.environ.get('PYTEST_CURRENT_TEST').split(':')[-1].split(' ')[0]
driver = driver_fact.get_web_driver(browser, browser_version, platform, os_version, test_name)
print(driver)
browserstack_obj = BrowserStack_Library()
active_session_id = browserstack_obj.get_active_session_id()
driver.maximize_window()
request.cls.driver = driver
yield
driver.quit()
global video_url
video_url = browserstack_obj.get_session_url(active_session_id)

@pytest.mark.hookwrapper
def pytest_runtest_makereport(multicall, item):
pytest_html = item.config.pluginmanager.getplugin('html')
outcome = yield
report = outcome.get_result()
extra = getattr(report, 'extra', [])

if report.when == "call":
    extra.append(pytest_html.extras.url(video_url))
    xfail = hasattr(report, 'wasxfail')
    if (report.skipped and xfail) or (report.failed and not xfail):
        file_name = report.nodeid.replace("::", "_") + ".png"
        # _capture_screenshot(file_name)
        if file_name:
            html = '<div><img src="%s" alt="screenshot" style="width:304px;height:228px;" ' \
                   'onclick="window.open(this.src)" align="right"/></div>' % file_name
            extra.append(pytest_html.extras.html(html))
    report.extra = extra

Start at the function-scoped test_obj fixture and the pytest_runtest_makereport hook, tracing when video_url is assigned and when report.extra is populated. Reproduce the report with multiple tests and verify that each test row contains its own video URL.
