Document ln caveats

[millette]

Currently, ln builds on mkfifo to create a fs fifo. In dat-shell, we can currently

ln a-file-inside-dat.txt ~/filesystem-file.txt

And from another terminal:

tail ~/filesystem-file.txt
cp ~/filesystem-file.txt somewhere.txt

But unfortunately, neither mplayer nor vlc will play a video file linked in a such a way.

[millette]

I added a pseudo "ln" command, hoping to be able to launch mplayer or vlc from inside the dat, but alas, it does not work (yet). You can still (in dat-shell) cp 01-jon-kyle.mp4 ~/01-jon-kyle.mp4 and that will work.

Turns out, you can play the file with mplayer. You just need to specify a cache size, as in:

dat-shell dat://peer-to-peer-web.com/assets/01-los-angeles/videos/
(in dat-shell) ln 01-jon-kyle.mp4 ~/01-jon-kyle.mp4
mplayer -cache 1024 ~/01-jon-kyle.mp4

And that will work. After playback, the fifo (link) ~/01-jon-kyle.mp4 is deleted.

Next still will be to document it in the readme.

[millette]

For vlc:

cat ~/01-jon-kyle.mp4 | vlc --live-caching 2000 -

Sur mac vlc 2.2.6 :
❯ cat 02-jon-gacnik.mp4 | vlc --live-caching 2000 -
