[gentoo-user] slideshow on USB stick

[Joseph]

Is it possible to create slide show (pictures) on USB stick and play on a TV?

In the past I've used "dvd-slideshow" but that is a bit of work.  I had to re-size the pictures add background music etc.
DVD only holds 4GB 
USB sticks have larger capacity.

All dvd-slideshow and co. do is to resize images (that's a one liner with
imagemagick's convert tool) and then join them to compose a video file,
muxing it with the chosen audio tracks. You can easily do that with ffmpeg,
mencoder or some similar tool of your choice if the menu-driven program
doesn't let you bypass the dvd size limit.

A video file is the most universal format you can get, unless you want to
relly on the tv native player capabilities to do a slideshow, which would
also be just fine since any tv that has an usb port can for sure do
slideshows as well.

It may depend on specific TV brand and model that you own. For
example, my Philips branded HDTV can play a slideshow of images
(optionally with mp3 music in the background!) based on an XML
definition which was documented in the TV manual.

It depends a lot on the TVs you want to play the slideshow in. If it's a
specific TV, you can just check what does it support. I've seen some LG
TVs which were able to browse photos on USB mass storage devices, and
they probably had a slideshow feature, although I've never tried that.

If you're aiming at broader support, your best chance is really some
widely supported set of settings like DVD-Video, because some table DVD
players (and TVs too, I guess) will be picky regarding framerate, frame
size, codec and other settings. 

For example, technically you could grab some file container and codec,
set the framerate to the time you want between photos and just use the
photos as the video frames (I think ffmpeg allows you to do this, but
some containers have problems with exotic framerates). But I guess many
TV and table DVD players out there would just refuse to play that.

One thing, though, is that what only holds ~4GB is *a specific* format
of DVD media, there are DVDs with larger capacities, and I'd not be
surprised if the size was not restricted at all by the DVD-Video
standard (the file format, filesystem structure and codec
specifications, not the physical medium specifications).
