source tree? Are torrents source files or build artifacts?

Instead of a daemon, added \~/archive/torrent/ as a watch directory

will only upload to other TCP nodes.

I didn\'t find the issues with web browsers easier to deal with
using WebM files. I\'ll keep MKV and investigate further later.
See also {{{bug(9d75fe3a-b7e5-4cc5-9300-1054c7e981c0)}}}.
- State \"CANCELLED\" from \"DONE\" \[2020-12-28 lun. 11:01\]\
WebM is more web friendly than MKV. Right now there is no support
for subtitles, only translated screencasts.

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
- State \"TODO\" from \[2020-12-28 lun. 12:44\]
Ressurect the WebM file when experimenting with:
``` {.example}
$ git revert 2beab5441b4fcddc849cfc44b99547d49593691d
```
