## Memecache overview (4/4)
"Memes are opium for the people"
-- Karl Marx, on #meme-consumers
#pause
according to adc's logs and git://src.adamsgaard.dk/bitreich-memestats (not including annna):
* 581 of 4191 (14%) of memes have been mentioned more than once
* 124 of 4191 (4%) of memes have been mentioned more than three times
* Meme use has a positive feedback
#pause
>>>> MEME ENLIGHTENMENT <<<<
#pause
* See old memes and keep up to date on new memes with low user effort
* Watch videos and images as a/v-stream: bitreich-tv
## Non-video memes
images: sound: other:
52 .JPG 3 .mp3 1 .css
2 .PNG 2 .ogg 5 .pdf
35 .gif 4 .wav 2 .svg
1 .gifv 7 .txt
1 .ico 9 .vt
1485 .jpg 1 .vtt
31 .jpeg 2 .vtv
% no bmp memes yet
% ATM: only handle image and video files
#pause
brtv-imgs-to-video.sh
1. convert(1): scale image to fit 16:9, add padding if needed
2. ffmpeg(1): image -> 10 s video clip
## Transition slides
brtv-generate-title-slides.sh
1. convert(1): create image with logo and meme hashtag
2. ffmpeg(1): image -> 5 s video clip
## Beam™ memes to streaming server
* Synchronous meme enjoyment
* Inspired by Bitreich Radio
* Encode memes to common codec
* Stream all video clips in random order to server
* mkvserver_mk2 (fork of now-deprecated ffmpeg server component)
* vlc(1)
* icecast(1) (with blank fallback stream in same codec)
#pause
* Very unstable, dropped clients (even with large buffers)
#pause
* Encode one randomized 24h #long meme video for each day
## wait..
* Simple solutions
* Why duplicate and reencode?
* Let the client TCOB
* Gopher
% bitreich is promoting simple solutions
% encoding hours of media every day != simple
% gopher is the way to go, not icecast and friends
## Another approach
* mpv(1) supports .m3u and .pls playlists with gopher:// URIs
#pause
brtv-generate-playlist.sh:
Outputs playlists with title slides
* Videos hosted at bitreich.org/1/memecache
* Titles and img->video hosted at adamsgaard.dk/1/{title,img2vid}
#pause
brtv-playlist-to-m3u.sh:
brtv-playlist-to-pls.sh:
Convert playlist from stdin to .m3u/.pls, adds hashtag as metadata title to current video
## Examples
all.m3u:
sort -R "${annna}/modules/hashtags/hashtags.txt" | \
brtv-generate-playlist.sh | \
brtv-playlist-to-m3u.sh > all.m3u
#pause
corona.m3u:
grep -E "^#corona-" "${annna}/modules/hashtags/hashtags.txt" | \
sort -R | \
brtv-generate-playlist.sh | \
brtv-playlist-to-m3u.sh > corona.m3u
#pause
news.m3u:
(cd "${annna}" && git log --all --pretty="%s" --date=relative --since="2 days ago") | \
grep 'Adding #' | sed 's/.* #/#/;s/ .*//' | \
while read -r tag; do
grep "$tag" "${annna}/${tagfile}" | head -1
done | \
sort -R | \
brtv-generate-playlist.sh | \
brtv-playlist-to-m3u.sh > news.m3u
