Can't play Video-Stream in Sandboxie [Opera 45 +]

Seems like Sandboxie and MFDemuxer used in Opera browser have compatibility issues.

Running Opera sandboxied
When MFDemuxer is enabled in Opera browser, some media files cannot be played due to error of loading, for example :

http://www.ligonier.org/learn/series/pr ... -question/?

When MFDemuxer is disabled under Opera flags, the same media files will play normally.

Running Opera unsandboxied
When MFDemuxer is enabled, the media files will play normally.


Starting from Opera 49 Developer, the flag to disable MFDemuxer has been removed and MFDemuxer is enabled by default.

Can the Sandboxie developers look into this ?

Have you only seen this since Opera 49?

We have a couple of known issues that sound similar that started on Opera 45:

Hi Jim,

I believe this "Opera browser cannot load media" issue is the same as the ones that were started and raised to Sandboxie developers' attention since Opera 45.

I had experienced this issue since Opera 45 after Opera developers decided to enable MFDemuxer by default when users complained they could not play some video medias.
I was able to workaround the issue by going to Opera://flags to disable MFDemuxer until the recent Opera 49 Developer release when their developers decided to enable MFdemuxer by default and also remove MFDemuxer option in Opera flags

This is what the Opera developer reply to this issue :
"MFDemuxer was already enabled by default and we want it to fully replace IPCDemuxer . Do you have any specific example why you would want to turn it off and keeo using IPCDemuxer?

Eventually Mac demuxer will follow this. Currently still in stabilisation phase fixing bugs which appear but eventually we will remove the flag after it has been enabled." (http://disq.us/p/1lu1rgf)

Can Sandboxie developers now look into this issue with more urgency ?

I had this very issue in Opera 45, reported it in 46 and had it in 47, too. I can confirm that the fix you suggested actually worked for me (currently running Opera 47) and I have not had any problems playing any sort of media afterwards.
So I guess you really did find the solution there. Thank you so much for that, nanana1! You are awesome! It really improved my sandboxie experience.
I just hope the developers can fix this issue before they release Opera 49 and we can no longer use your work-around.

A shout-out to Sandboxie developers to adopt more urgency to look into this audio/video streaming issues as Opera 49 turns Beta today :

A reminder that Opera 49 removes the workaround fix

Hello nanana1 ,

The devs are aware of the issue.
I will post new information whenever it becomes available.

Regards,
Barb.-

Another shoutout to Sandboxie developers as Opera 49 Release Candidate was announced yesterday which means it will likely go final next week.

Opera 49 is now final and stable version released today and still no solution from Sandboxie developers yet

I can confirm that with Opera 49 and Sandboxie, certain videos will no longer play such as: http://www.stuff.co.nz/life-style/food- ... -cat-cafes because the browser setting that enabled them to play under Opera 48 (opera://flags/#media-windows-mf-demuxer) was removed.

The same with Opera 50...

Dear developers!
Are not you ashamed to ignore such a serious problem for so long?
Opera browser (and you will not deny that this is one of the most popular browsers?) does not play streaming audio on sites for a long time.
One of the most valuable features of Sandboxie is the ability to launch your favorite browser in the sandbox.
Buying your program, I thought I could do it.
Please, do the work and fix the problem!
Thank you!

Still not fixed in Sandboxie 5.24 and Opera 51.
