I seem to have solved my radio problem. After writing the other post I was inspired to google "linux multimedia library" rather than "linux multimedia player" and found Songbird. It has auto playlists and the ability to update those playlists as they are playing so it looks like it will work for my purposes (without the cron job). It also has the ability to build auto playlists out of other auto playlists, so I'm trying different methods to mix in music with my podcasts. I'm still interested in other suggestions, so if you know of a better setup, let me know.
Ok, So for a while now I've been wanting to build a Podcast Radio. The idea is to take an old junker of a computer and convert it to a file server that downloads podcasts as well. The radio portion of this project is that I want it to continuously play said podcasts so I can just switch the speakers on when I want to listen.
When I found an old computer at a garage sale for $20 (384 MB RAM, 1.2 Ghz AMD Athalon, 40 gig HD) I jumped on it. I've installed Ubuntu for the OS, Samba for sharing, and Gpodder for the podcast downloading. (I also installed F@H for the fun of it and Conky so I can see the folding progress). I have it all set up and I access the GUI via VNC.
I've gotten it to do everything I want except for the radio portion. I've been poking around with the advanced settings in gpodder and found I can have a custom command run whenever a new podcast is downloaded so my thought was to have it open and play an auto playlist in Rhythmbox whenever a new file was downloaded, that way the newest download is started and overrides the current playing track. I've had a few problems with this though.
1. Rythmbox doesn't appear to scan set folders for new media as I'm used to in WMP.
2. Any attempt I've made to create an auto playlist (one that builds a track list from set criteria) has resulted in the program crashing.
3. Gpodder's help wiki is down (has been for some time) and as such, I can't find any syntax information for the command.
Honestly all I need is a music player the can automatically scan a folder recursively for new tracks, keep track of a playcount, and play auto playlists. I can then use a cron job to restart the playlist every 6 hours or so. Does anyone know of such a player?
