Hi Hanno,
Here is the discussion on tests that you have made,
SC1-2-2-video-element-without-track and SC1-2-2-video-element during the
autowcag meeting on 2014-09-25. This is a compilation of comments on the
discussion page of each test and descriptions of comments and new
suggestions.

Best Regards,
Kamyar

Review 1.2.2 Video without tracks:
https://www.w3.org/community/auto-wcag/wiki/SC1-2-2-video-element-without-track

Most comments are in the discussion page on the wiki already:
https://www.w3.org/community/auto-wcag/wiki/index.php?title=Talk:SC1-2-2-video-element-without-track&oldid=581

- Step 1 should be manual. There is no aria role to specify content as a
media alternative to text.
- This page doesn't use the same logic flow as the test on for example
this page: https://www.w3.org/community/auto-wcag/wiki/SC4-1-1-tag-nesting
- A few of the steps do contain outcome tables but don't explicitly
state when to return those outcomes (although most of the time it is
clear from the text). For example "For each spoken audio fragment the
frame contains text" (step 4) could be
- Testmode is missing on each step and selector.
- "IF NOT for each spoken audio fragment the frame contains text: RETURN
{{{id}}}"
--Wfiers

- Suggestion: Move the manual steps that check open captions to a
separate test. This test could be applied to other videos as well (not
just video elements).
- The test mode of the steps should be either automatic or manual.
SemiAuto should not be used (in step 1 and 2). In this case the step
should be spilt into two steps.
--Anietzio

Birkir: We may add a separate technique for flash to automatic detection
of flash videos. The flash objects needs to be asked if they contain
video. Wilco: there is no any technique to detect videos. However, video
players can identify them.

SUGGESTION: Extent this test to object element. Look at video and object
elements to capture all of the possible variation of it.

Comments on discussion page:

- This page doesn't use the same logic flow as the test on for example
this page:
https://www.w3.org/community/auto-wcag/wiki/SC4-1-1-tag-nesting
- A few of the steps do contain outcome tables but don't explicitly
state when to return those outcomes (although most of the time it is
clear from the text). For example "File content contains time codes and
text" (step 4) could be
"IF File content does't contains time codes and text: RETURN
SC122-videoelement-fail#"
- Testmode is missing on each step and selector.
- The page states "success criterion doesn't take into account language
changes. So it is valid to have spoken text in language 1, subtitles in
language 2 and page content in language 3." But I would argue that in
that case the captions are not an equivalent to the audio track.
--Wfiers

- Suggestion: Add reference to Technique H95
- Selector: There is not track-attribute in HTML5. It should say: "track
element with kind attribute".
- Step 2: Not clear what happens if the attribute is found.

Something is missing from description. Maybe it should say “go to the
next step”. Not clear do we treat subtitles different from captions...
Suggestion: Step 1 and Step 2 could be merged to the selector because
there is no difference in how captions and subtitles are treated.

- Step 8: What is the intention of this step? Why is there no need for
further testing for 'talking head' videos?
Suggestion: Remove this step.
- Step 10: What is a "background fragment"? Step 11: What is a "speaker
fragment"? Please clarify.
- Suggest to split this test into two parts. (1) automated part checking
for the presence and correct format of the file. (2) Manual check that
the captions describe the video.
- The test mode of the steps should be either automatic or manual.
SemiAuto should not be used (in step 6 and 8). In this case the step
should be spilt into two steps.
--Anietzio

SUGGESTION: remove the graded rating scheme from these tests.
SUGGESTION: We do not include synchronized media in to selector. We just
select video in object element, we can automate that, otherwise we have
to ask user to verify every page with synchronized media.
