Add support for uploading and recording videos

[nicolas-raoul]

including transcoding to Wikimedia-accepted format

Warning: We have to pay special attention to quality (on-topic, encyclopedic, good technical quality). A 2021 photo+video contest ended up with hundreds of high-quality photos but only one high-quality video.

Commons only accepts WebM (VP8, VP9) and Ogg Theora videos.

This converter could be useful if converting on Android proves inconvenient: https://tools.wmflabs.org/videoconvert/index.php
I see a "Auto upload to Commons after conversion is done?" option which is checked but the video does not get uploaded...

2020 update: Now seems to be at https://videoconvert.toolforge.org

This was suggested on the grant talk page:

"I have two additional features to request which could probably make use of the storage and batch processing infrastructure of https://tools.wmflabs.org/video2commons/ - this would allow the uploading of videos and audios - whose formats are difficult to manage otherwise.

Audio/video support is a suggestion I receive pretty often. Might be worth considering this for a future grant.

Also, should I create an additional issue for audio?

@Brion has offered to help implement this, yay! :)

We should talk about how to best handle potential video-selfie-pocalyptic issues, too. I personally think that it would suffice to have a simple addition to the tutorial or a tooltip, when the feature is implemented... but am open to other suggestions.

My rough plan is to test on-device transcoding to VP8 or VP9 since that can make use of the device OS and hardware codecs -- Android provides most of the plumbing needed. Performance will make or break this, but I think it should be adequate...

It might be possible to combine transcode and upload into a single pass, but I'm not sure of that (depends on if we need the final file size before we start, I forget).

I'm busy with a conference the next couple weeks; will start experimenting with the Android transcoding mid February.

Having the ability to upload video directly from my phone using the commons app would be wonderful. Just took some video of leaping benny, a fish, and the still images do not do them justice.
