Hi John, Could you help check if there is any way to fix this probelm from APP side? For example, when user choose the "Share" button, stop/unload the current video tag to make it shutdown?
Hi Blake, The email and SMS app use inline activity to receive the share activity now. In the design of window management in System app, we don't receive the visibility change while opening inline activity. That's the reason we don't release the video element. As per offline discussion, we may use onsuccess and onerror of mozActivity to tell if the inline activity is closed. If we face a window activity, the onsuccess and onerror will be called immediately and a visibility change event is received. So, using onsuccess and onerror may be a choice to fix it. The flow may be 1. call releaseVideo before creating mozActivity at  2. call restoreVideo after onsuccess or onerror received And, we may introduce a race condition in "window" activity because we will also receive a visibility change event in this case.  https://github.com/mozilla-b2g/gaia/blob/eb8a140841f2fb2d8f28f45cbfd0bb053d8aa187/apps/video/js/video.js#L623
Hi John, Thanks for your help! I found when user finishes selecting a video, that video will be loaded to get ready to play. Maybe we should not need to do that, just put it to message. If user want to watch it, she/he can click it in the Message APP. Thumbnail should be enough for user to identify which file he/she wants to attach.
Confirmed with partner, launch blocker. Hi John , per comment 7, would you please kindly check this and provide patch? Thank you very much.

Hi John, I tested Bug-1088456 patch.But this issue is not yet resolved. So would you please recheck In Version2.0 Thanks.. Sireesha
Sireesha, You are correct. We still need a patch to fix it. The root cause of this issue is the same as bug 1088456., but the behavior is different. The bug 1088456 has one video app index.html frame and one video app view.html frame. And this issue has two video app index.html frame. The patch of bug 1088456 only let index.html frame know that the view.html frame wants to use hardware decorder. But this issue needs let index.html frame know that another index.html frame wants to use hardware decorder. David, This issue is similar to bug 1088456. Would you mind to take it?

Summary: [MADAI][Multimedia] MediaDecoderStatemachine instance isn't changed to SHUTDOWN state when sharing a video with message app while playback → [MADAI][Multimedia] can't play video received from the video app via an inline share activity because the hardware is already in use
Thanks for the analysis John. It does sound very much like 1088456, and we can do a similar fix here. For master, though, I think that the right way to go is to convert apps that implement the share activity to use window disposition instead of inline.
Assignee: nobody → dflanagan
If I fix this like I fixed 1088456, I think I should probably just revert that patch and land one here to fix both bugs.
Hi David, Thanks for your feedback. Just to be noted, this is requested by partner as a launch blocker. Thank you very much!
Created attachment 8517448 [details] [diff] [review] Bug_1085212.patch Hi David, Would please provide me the feedback for this workaround. If this patch is ok..i will upload the PR with areview changes if any. Thanks.. Sireesha
Attachment #8517448 - Flags: feedback?(dflanagan)
Comment on attachment 8517448 [details] [diff] [review] Bug_1085212.patch This is basically the patch that John suggested and what I was thinking of doing at first. Except that I would have updated the comments more. But if you need to land that patch today in the 2.0 tree, I'd be okay with it. (Note that you'd have to uplift 1088456 first, of course.) But after thinking about this some more, the bigger issue is that if the share activity is inline, then no app that handles the share will be able to play the shared video. In my patch for bug 1088456, I added code that would pause playback before allowing a share to begin. But that isn't actually enough. I think we need to release the video hardware when a share begins and restore it when the share ends. We have releaseVideo() and restoreVideo() functions in 2.0, but we just recently removed them from master and 2.1 as part of bug 1082563. If we put these functions back, then we can call releaseVideo() when we start a share, and then call restoreVideo() when the share ends (for the inline share activity case) or when we next become visible (for share activities that are correctly configured to use window disposition.) If we fix this bug that way, then we don't need to abuse the localStorage mechanism any further because we will never be holding the video hardware when we share a video. Also it will make this patch independent of the patch for 1088456.

Once again, John's analysis in comment #7 is very helpful here!
Specifically, John says in comment #7 that window disposition activities trigger an onsuccess immediately, so we can safely release/restore without considering visibility at all in that case. But as John points out, since v2.0 still has release/restore being called on visibility change, we have to look out for race conditions in that release. In 2.1 and master we don't have to worry about that because if we put the release/restore functions back we won't use them on visibility change and will only care about the share activity.
Hi David, Thank you for your feedback for the patch attached. Same modifications applied for V2.0 branch as well and it working fine for all cases. Coming to your comment#20 says about V2.0 release/restore functions will be called on Share activity case and this change will not use localstorage. But this change will recreate the Bug-1088456 because view.js don't know about video.js is already playing.So i feel the localstorage or some bridge is needed to communicate between view.js and video.js. Comment#22 will it really create race conditions..i don't know. As per my understanding, for Email case both 'storage' and 'visibilitychange' will be fired. But in your patch(Bug-1088456) will check the document.hidden etc case as well. So as a summary for this issue Bug-1088456 patch(need to remove the playing check in 'storage' event handler and also playershowing also wont work,not sure) is also required along with my patch. Please correct me if my analysis is wrong for V2.0 case.
vsireesha, You are correct that bug 1088456 should not have tested for 'playing'. I think that 'playerShowing' will work instead. That was my mistake, and I plan to correct it in the version of this patch that I apply to 2.1 and master. If you end up taking bug 1088456 into your 2.0 tree, then you'll want to make that change as well. The rest of this patch should be completely independent of 1088456.
Created attachment 8518579 [details] [review] link to patch (for master and 2.1) on github Another video review for you, Russ. This one prevents hardware contention during inline share activities by resurrecting the release/restore functions that we got rid of recently, but only using them when we share. It also adds a tweak to the code for the 1088456 patch to make it work correctly even if the video is paused. I'll need to create a different patch for v2.0 since that branch still has release/restore in use.

Comment on attachment 8518579 [details] [review] link to patch (for master and 2.1) on github vsireesha: does this patch look to you like it will work? It won't apply on the v2.0 branch, but I'll create a version that does. Feel free to test on v2.1 or on master, if you can.

Comment on attachment 8518893 [details] [diff] [review] Bug_1085212_V2.0.patch Review of attachment 8518893 [details] [diff] [review]: ----------------------------------------------------------------- I see two problems with this patch. 1) It includes all code from 1088456. I don't think that is necessary to fix this bug, and if we want to handle that bug we should separately make that uplift decision in 1088456. 2) it includes the new needsRestore variable, but never sets it. Since this version of the code still uses release/restore on visibility change, we need this flag to prevent the video from being released twice or restored twice. In particular this is a concern for share activities that use window disposition. We don't want to break those while fixing the inline activity case.

Created attachment 8519080 [details] [review] Link to v2.0 patch on github Russ, This version of the patch is different because the 2.0 branch still has the old releaseVideo/restoreVideo code available. Also, I've taken part of the 1088456 patch and included it here: just the part where we pause playback when the menu is shown. I'm not doing anything with the localStorage hack in this bug. (That is a separate and more obscure bug and its uplift decision should be separate from this one.) vsireesha: this patch works for me and fixes the pick and view bugs described in comment #0 and comment #14. Do you agree that this patch is sufficient to resolve this bug?

Comment on attachment 8519080 [details] [review] Link to v2.0 patch on github NOTE: Please see https://wiki.mozilla.org/Release_Management/B2G_Landing to better understand the B2G approval process and landings. [Approval Request Comment] [Bug caused by] (feature/regressing bug #): not a regression, just a bug that we never noticed before. Or maybe a regression caused by window management changes for 1.3T to ensure that apps that initiate inline activities don't get OOMs. [User impact] if declined: Important video->share->sms->view/pick->video activity flows will be broken with no error messages. [Testing completed]: yes [Risk to taking this patch] (and alternatives if risky): not very risky. The patch uses existing code to release and reclaim the video hardware and just calls it before and after the share activity. [String changes made]: none
