Asserts will be faster since things will be already in memory.
Should the generator for the torrents put the torrent files in the
source tree? Are torrents source files or build artifacts?

## DONE Add webtorrent-hybrid daemon {#task-1a2f5619-5d55-449f-a401-8c87afd5bea9}
- DONE in 2020-12-28
Instead of a daemon, added ~/archive/torrent/ as a watch directory
to Transmission. It doesn't work with WebRTC (yet), so Transmission
will only upload to other TCP nodes.

- DONE in 2020-12-28
I didn't find the issues with web browsers easier to deal with
using WebM files. I'll keep MKV and investigate further later.

- CANCELLED in 2020-12-28
WebM is more web friendly than MKV. Right now there is no support
for subtitles, only translated screencasts.

## DONE Fix play of videos with WebTorrent {#task-9d75fe3a-b7e5-4cc5-9300-1054c7e981c0}
- DONE in 2020-12-28
Done when moved to WebM. Firefox gives an error when loading the
file directly, and a different error when loading with WebTorrent.
I'll call this a Firefox error, since Chromium was able to play the
video on both, since both the file creation and serving are pretty
straighforward.
When loading the file directly, Firefox says with `console.warn()`:
```
Media resource https://euandre.org/screencast/2020/12/24/sample-screencast.webm could not be decoded, error: Error Code: NS_ERROR_DOM_MEDIA_DECODE_ERR (0x806e0004)
Details: virtual mozilla::MediaResult mozilla::FFmpegVideoDecoder<46465650>::DoDecode(mozilla::MediaRawData*, uint8_t*, int, bool*, mozilla::MediaDataDecoder::DecodedData&): avcodec_send_packet error: -1
```
When loading with WebTorrent, Firefox says with `console.error()`:
```
Uncaught Error: XDR encoding failure
```

Ressurect the WebM file when experimenting with:
```shell
$ git revert 2beab5441b4fcddc849cfc44b99547d49593691d
