I finally got things set up, and I'm very close, but not quite there...

I'm using Ubuntu Jaunty. I compiled ffmpeg (and x264) according to the link in Laughing Man's post. I opened port 1978 on my router, the path to ffmpeg looks right, and I have successfully added directories to my collection.

I can browse the media on my tablet, and when I select a video or music track, it goes to the player and the slider starts moving but nothing plays (no audio or video). Sometimes the slider moves very quickly along the track, and other times, when playing mp3s, it jumps to the end of the track suddenly...

Any ideas?

Exactly what I got too. So I am not alone

! You only open port if you want to access outside of your LAN, right?
I was suspecting the VLC so I downloaded the VLC 1.0.0 for linux (on the server) too but it only help a little; i.e. it stays for 10 15 sec with no sound then jumps to the end.

Yes, I want to be able to access outside of my LAN, so I open port 1978.

I am using vlc 0.9.9a-2ubuntu1 and ffmpeg 3:0.svn20090713-12ubuntu3-1 that I compiled using these instructions. I'm wondering if I need to add options to the ffmpeg compile?

A feature request: I would like to be able to enter a DNS name, rather than an IP address for the server.

EDIT: Here's what I get when I type "ffmpeg" at the command prompt:

Code:

ffmpeg seems to have the necessary codecs for Knots. libmp3lame is needed for audio and xvid is needed for video. Any VLC from 0.9.4 to 1.0 should work ok. To view stuff from outside your lan you also need to open ports for the actual vlc http streams. By default it uses 19780 and if you want to be able to view multiple streams, you need to increment that with as many streams you need. Basically 19780 to 19785 should be enough.

Doesn't the dns name work instead of ip?

I opened up 19870-19875, but that didn't help... Pretty much the same symptoms... Now music just closes right away, and video "pretends" to play as I stated above...

EDIT: Local in-browser play on the Ubuntu server works, via FlowPlayer.

Aha. When I change my transcoding profile on the Ubuntu server from "Browser" to "Nokia N8x0", the file doesn't play on the server, either. In fact, the FlowPlayer displays exactly the same symptoms as the tablet.

All of the other profiles work. So what's the problem with xvid / mp3 / asf ?

I have proof that debian-testing works pretty much out of box.

I would like a command line to transcode video using the N8x0 profile, so I can see some debugging info and figure out what's going wrong on my server.

I'll write a script that does that.

EDIT: try this: vlctest

Copy this script inside knots/scripts, chmod +x it and run it from knots root with ./scripts/vlctest /path/to/a/video and try to find error messages from the output (with -vvv there is a lot of it, you can also try -vv or -v if you want). You can also try to view the stream with mplayer http://serverip:19780/stream.asf and see what mplayer thinks of it.
