Google Drive does not play mp4 video

[LaurenWags]

Description

Google Drive will not play .mp4 video. Disabling shields and attempting to play the video does not allow video to be played and console shows errors.

Steps to Reproduce

1. Clean profile 0.55.3
2. Login to Google Drive
3. Attempt to play an .mp4 file --> see notification in URL bar about autoplay being blocked. (autoplay allowed but URL bar still reads autoplay blocked #1120)
4. Click on this and choose to Always Allow, video still will not play, console errors.
5. Put shields down, video still will not play, console errors.

Actual result:

mp4 video will not play (shields up or down):

console errors: https://gist.github.com/LaurenWags/bda1b03eaeda8a3b8060b68cfd01ff8b#file-autoplay-txt

Expected result:

Video should play, no console errors.

Does this work on browser-laptop?

[darkdh]

Does it play after you choose "Always allow" and click "Done" then do a manual refresh?
This kind of dropdown dialog has a general defect which is it will not auto refresh/or prompt to reload when setting changed.

Some content settings required to reload the page when setting changed not just limited to autoplay.

[LaurenWags]

@bbondy tested on browser-laptop with 0.23.107 worked without issue. Steps:

1. Clean profile on 0.23.107 (release version)
2. Login to Google Drive
3. Double click on an .mp4 file --> file displays and plays without issue.

[LaurenWags]

@darkdh I don't see that message displayed. I don't get an Autoplay prompt at all (to the left of the URL bar) like I would expect. I only see the message to the right telling me Autoplay is blocked:

When I click on that I change the radio button to Always Allow and nothing happens. Reloading the page has no effect - I am still unable to play the mp4 file (shields up or down).

If you want to look at this together let me know.

This should be working, per having the following set:

brave-browser/lib/config.js

Lines 63 to 64 in 0e2e3a2

	proprietary_codecs: true,
	ffmpeg_branding: "Chrome",

[bbondy]

This is also happening on Android so moving this to the backlog since it doesn't seem like it would stunt growth relative to other issues.

[bridiver]

This looks like fingerprinting protection is not getting disabled with shields down

[bridiver]

I think we should fix the value to 100%

[bridiver]

fixing the battery api does not fix the problem per @bbondy, but if we are moving forward with fixing to 100% we should open a new ticket

We appear to still be having issues here.

@bizfreak22 @timelessthee @cliffordp can you please try updating to the latest version (if you haven't already) and then try this again? 😄

I've tested this, seems to work only when allowing 'Allow all cookies' in shields.

[ryanbr]

From a new profile Brave Beta (Version 1.4.84 Chromium: 80.0.3987.87 (Official Build) beta (64-bit))

Just for the record of the cookies are being blocked in google drive:

[ryanbr]

1. Tested with Brave Beta, removed old profile.
2. Logged into gmail, click on the google drive link (top right)
3. View cookies on google drive. see Allowed/blocked items.

Not sure how reproducible it is, closing and re-opening seems to change this

[pes10k]

I believe this should be closed as of brave/referrer-whitelist#26.

There may be additional issues here (could be additional cookie related issues) but getting the referrer part straightened out is at least a necessary, if not sufficient, step

[pes10k]

This requires additional storage exceptions for as added in brave/brave-core#5313

[cryptogrounds]

Still an issue.
Edit: Disabling shield finally got it to work, but this only works if video is added to drive, otherwise you cannot watch videos from google classroom (probably a separate issue)
