I imagine that most people saw this at the conference closing. However, for completeness and because I feel that if we’re going to put videos of other speakers online then I should suffer the same fate, here is the LCA 2013 announcement from Ballarat:

Couldn’t determine the video directory?
A couple of people have contacted me in the last couple of days with an error where MythNetTV can’t determine the directory to put videos in. The error would look something like this:
-
Importing data/tekzilla--0050--tehbunniez--hd.h264.mp4
Traceback (most recent call last):
File "./mythnettv", line 453, in
The stack trace is mostly irrelevant. The problem here is that MythNetTV couldn’t decide what directory to put the video in once downloaded. Please execute the following SQL statements against your MythTV database:
select * from storagegroup where groupname="MythNetTV"; select * from storagegroup where groupname="Default"; select * from settings where value="RecordFilePrefix";
This will dump all of the possible places MythNetTV will look for a video directory.
Once you’ve dumped this information, perform some simple checks:
- Is there anything listed at all? If not, you need to configure storage groups with the MythTV user interface
- Is there anything listed with the hostname that MythNetTV is running on? If not, you need to add configuration entries for your current hostname.
If you’re still having problems, please send email to mythnettv@stillhq.com, with the output of those select commands, and the output of the hostname command.
Open Source video creation
For the upcoming MythNetTV release I am toying with the idea of asking the user if its ok to include a default subscription to an announcement video blog. This blog could be used to inform MythNetTV users of things like new releases, and important bug fixes if such things happen.
This raises the question — if I wanted to mix creative commons licensed music with some still images (the announcements), what tool is the best to do that? Specifically open source tools please.

MythNetTV release 1
I figured it was time for another release of MythNetTV, especially since I’ve fixed some bugs recently and rolled in code generously provided by George Nassas. New things in this release:
- Initial work on transcoding smaller files to something else
- Better error checking for MySQL configuration and accessibility
- Fixed bug where MythNetTV was unhappy if there were no channels configured in the MySQL database
- Found, and hopefully fixed, a bug where program dates were not always being tracked correctly. Also added a check to make sure this doesn’t happen again
- Added –markread, which lets you mark old shows as already downloaded
The code has seen a fair bit of use now, so it should be fairly stable. Let me know if you find any problems…

MythNetTV beta 4
As it says in the email:
To: Discussion about mythtv <mythtv-users@mythtv.org>
Subject: MythNetTV beta 4
Hi again.
MythNetTv is my video downloader / aggregator / importer thingie for MythTV.
I've spent a little longer testing this beta, and I think it's getting
kinda ready for a real release number or something. New things in this
version (from the change log):
- Made --update more terse
- Made --update more liberal about what it considers to be a video,
specifically added video/quick time and text/html (to work around the
rather broken http://www.mobuzztv.com/uk/rss/quicktime
- Added a filter option to --download to constrain it to only
downloading shows with a specific title
- Added transcoding for mov and wmv2 files
- If there is a straggling import, and it causes as error, just skip
it and mark it as imported
- Don't reset transferred data statistic when we start downloading a
show again
- Started implementing moniker support for downloads
- Unsupported monikers will result in an attempt to download the URL
using mplayer (which works for RTSP and MMS at the least)
Yes, that's right. You can now download only shows with a specific
title, and you can also download any protocol which mplayer supports --
specifically, RTSP and MMS are now supported.
Now, if only there was a non-sucky way to work out what streams
abc.net.au were offering at any given time...

Kernel report video
The video of the kernel report is cool. It only has left hand audio though. I wish people would ask questions using the microphone though.
LCA 2007 Video: CFQ IO
I’m watching the CFQ IO Scheduler talk now on MythTV using my MythTV program downloader thingie. Beware the very large audio volume jump about three minutes in. Just saying.
Oh, and the “pan across blank blackboards for a bit at a funny angle” thing at around 6 minutes is pretty amusing too.
Update: now with working URL for the downloader thingie!
Mirror traffic during the last day of LCA 2007
It seems obvious to me that videos of LCA 2007 are good. Specifically:

Yay for LCA 2007 videos.
Avoidance behaviour, or, wanted: video RSS feeds
I’m avoiding doing paper work for work, and chapter edits for the MythTV book by writing a video aggregator. I have Media RSS feeds working, and normal RSS 2.0 with enclosures working. I have two questions:
- Are there any other feed formats I should worry about?
- What are some good (as in not horribly boring) feeds that I should now watch?
That’s right, I built the aggregator, before I had anything to aggregate. Now I have this hammer, and must hit things with it… I’ll talk more about the aggregator itself when I’ve done a little more testing, but I think it’s pretty cool.
