Yuhong added a comment to T191572: Please upload large file to Wikimedia Commons.

Note at the time of the upload that the WMF did not support MP4 or H.264 format. If this video is not HEVC encoded I am working on getting WMF to support uploading the original MP4. I think this is a better idea than relying on the 5GB increase.

Right now this limit is not even 4GB.

Part of the reason why I waited was to aim for something like HE-AAC.

In particular smartphone cameras often record in mp4, and support would mean that they would not have to be converted.

Though don't forget input as well as output, which is part of why I mentioned AAC.

I wonder however if this is a good time to make up plans for enabling this though.

I know. They even transcode Theora videos to WebM.

Question: should other profiles of AAC be enabled or just AAC-LC?

Answered the first one in recent comments. There is already an issue for enabling AAC.

I would prefer mp4 if possible.

Yuhong added a comment to T120288: Enable MP3 uploads on Wikimedia Commons and TMH playback.

It been 7 months since MP3 decoding support dropped in RedHat Fedora Linux, Chromium (the FLOSS fork that doesn't support H.264) will now have MP3 support. Will Wikipedia be the last Open Source project to get MP3 support?

Since all browsers will have playback support (no need to transcode). I suggest before Wikimania (Aug 9) we allow .mp3 uploads T162395.

@CKoerner_WMF I think the most important thing that needs to be understood here is that any decision to enable mp3 uploading on Commons that is not implemented as the result of a explicit decision by the Commons community is likely to end badly. Now that the legal issues have been cleared up, and it's established that the technical implementation is not a problem, most of this discussion really needs to move onwiki, so that the community as a whole will have an 'investment' in the process of deciding how it is implemented. If a plan such as yours (which is not bad) is presented to the community as a 'fait accompli', even if merely for discussion, there will be grumbling.

If the decision is presented to the community as a request for them to 'rubber stamp' a process that has been predecided, not only will it get complaints at the time, but if there are issues then the WMF is likely to be blamed. It's unfortunate, but realistic.

Yuhong added a comment to T166024: Once it's not patent-encumbered, enable MPEG-2 support for Commons uploads and TMH/etc. playback.

There are already very few patents remaining on MPEG-2. It is probably not as important as MP3 though.

Yuhong added a comment to T88507: The certificate chains of newly installed SHA256 certificates are incomplete..

This is a myth. "RapidSSL SHA256 CA - G3" is definitely SHA256. The other intermediate is for compatibility with older clients such as XP/Server 2003 (but note that XP has root certificate update enabled by default).
