(port) > Thunderbird + YouTube + RSS

I thought YouTube didn't do RSS any more, but Brad left a comment with details. They are untested.

RSS was tested with YouTube subscriptions. While it can do it, it's atrocious. It doesn't get everything, and doesn't get new items even a week later, and it keeps showing duplicates. It's horrifically slow.

Preparations and local notes ∞

• prep a local account

• prep a youtube account

--

• universal settings for FFmpeg

SETTINGS="-y  -ac 1  -ar 44100  -r 30  -sameq"

Making image movies ∞

• make your image. I used KolourPaint:

\kolourpaint  ~/01a-kolourpaint1.png

• control-e and change the canvas size to 640x360.

--

• Convert it to a video, and append an empty sound track using FFmpeg:

# (from above)
SETTINGS="-y  -ac 1  -ar 44100  -r 30  -sameq"

\ffmpeg  $SETTINGS \
  -loop_input \
  -vframes 200 \
  -i ~/01a-kolourpaint1.png \
  -f s16le \
  -i <(dd if=/dev/zero bs=19200 count=1) \
  ~/01a-kolourpaint2.avi \
` # `

2017-07-30 - Note that the use of dd might have had a formatting issue and may actually be:

  -i < $( \dd  if=/dev/zero  bs=19200  count= 1) \

01 - Intro ∞

This video will show you how to import your YouTube subscriptions as Thunderbird RSS feeds.

These instructions are made for Linux, but the ideas are fairly universal, and can be adapted to your situation.

(Cheese)

\cheese
# Click 'video'.  Press space to begin and space to end.  Then exit.
\mv  ~/.gnome2/cheese/media/0001.ogg  ~/01b-cheese1.ogg

• convert the video to an editable format

• Resize from 320x240 to 640x360.

  • The closest is 480x360, with a pad of 80 on the left and right.

# (from above)
SETTINGS="-y  -ac 1  -ar 44100  -r 30  -sameq"

SIZE=480x360
TOP=0
BOTTOM=0
LEFT=80
RIGHT=80

\ffmpeg  \
  -i ~/01b-cheese1.ogg \
  $SETTINGS \
  -s $SIZE \
  -padtop $TOP \
  -padbottom $BOTTOM \
  -padleft $LEFT \
  -padright $RIGHT \
  ~/01b-cheese2.avi \
` # `

--

• chop the ending off with Avidemux (instructions are not included here):

\avidemux2_gtk  ~/01b-cheese2.avi

• Save it as ~/01b-cheese3.avi

02 - Export your YouTube subscriptions list ∞

Next I'll show you how to create a text list of your subscriptions. There are several ways to do it, but this is the most straightforward way I've found.

• https://youtube.com/account

  • Email Options > Subscription & YouTube Updates > Show Subscriptions

• paste it into a text file (I used mousepad):

\mousepad  ~/subs.txt

• Using recordmydesktop:

\gtk-recordMyDesktop

• Click "Select Window" and click the window you want.

• Click "Record" to begin and left-click the tray icon to stop. Then exit.

\mv  ~/out.ogv  ~/02b-recordmydesktop1.ogv

• Determine the dimensions of your video with FFmpeg:

\ffmpeg  -i ~/02b-recordmydesktop1.ogv

• Convert the video

• Calculate the resize and the padding needed.

  • Example: 1008x672 becomes 540x360 with a left and right of 50

# (from above)
SETTINGS="-y  -ac 1  -ar 44100  -r 30  -sameq"

SIZE=540x360
TOP=0
BOTTOM=0
LEFT=50
RIGHT=50

\ffmpeg  \
  -i ~/02b-recordmydesktop1.ogv \
  $SETTINGS \
  -s $SIZE \
  -padtop $TOP \
  -padbottom $BOTTOM \
  -padleft $LEFT \
  -padright $RIGHT \
  ~/02b-recordmydesktop2.avi \
` # `

03 - Process your YouTube subscriptions list ∞

• Create a 640x360 window.

  • If your window manager doesn't show the dimensions as you resize, you can use wmctrl. I can use it on an xterm window and it'll define the proper area even though I have Openbox set to resize to the nearest character in fixed-font windows:

\wmctrl  \
  -F  \
  -r "user@localhost: /home/user"  \
  -e 1,0,0,640,360 \
` # `

# -------------------------------
# Process your subscriptions list

# Remove all tabs
\sed  '/[\t]/ s/[\t]//g' \
  ~/subs.txt \
  > ~/subs2.txt \
` # `

# Separate all favourites into another file.
# NOTE: These aren't always subscribable because of a YouTube limitation / security issue.
#   So I'm not doing anything more with these..
\cat  ~/subs2.txt |\
  \grep \'s\ Favorites \
  > ~/subs-faves.txt \
` # `

# Separate all non-favourites into another file.
\cat ~/subs2.txt |\
  \grep -v \'s\ Favorites \
  > ~/subs-nofaves.txt \
` # `

# Remove all spaces
\sed  '/ / s/ //g' \

\mv  --force  ~/subs-nofaves2.txt  ~/subs-nofaves.txt

# Remove the working file, but keep the original subs.txt

• download and install it
• set up an empty RSS account

• manage subscriptions, import the OPML textfile

  • NOTE: Thunderbird is completely unforgiving of issues with your .opml file!
  • NOTE: Cannot re-import duplicates!
• prep the list of unread items
• prep the list of starred items
• get mail, and wait patiently

• Manually mark each folder as unread (right-click k)

  • is there a better way?

tutorial creation - Combine files ∞

Using Avidemux, open the first video and then append each subsequent video to it.

settings:

• video: MPEG-4 ASP (Xvid4)

• audio: MP3 (LAME) - and with an audio filter:

  • Resampling: 44100
• format: MP4

• save it as ~/final.mp4

Things to improve ∞

• Include a "New this week" search folder, and sort by date.
• How can I subscribe to someone's favourites with RSS?
• Replace the use of the search-and-replace in kwrite with some commandline voodoo.
• How do I easily all the items in mark multiple folders as read?
• Include JavaScript
• How do I enable Flash?

• How do I block ads?
