Mercurial pattern matching example

This is how to remove all .o and .a files in a mercurial repo:

hg remove -I "glob:**/*.o" -I "glob:**/*.a" **

Edit: The file patterns must be enclosed in double-quotes "" (at least on Windows). Single-quotes will not work.

Running mythfilldatabase as cronjob

Made a script calling grab_dk_dr and mythfilldatabase sequentially. Running that as cronjob of user mythtv.

For some reason the mythfrontend's autorun of mythfilldatabase didn't work.

Note: I had to configure mythfilldatabase to use tuner 2 after changing to anysee tuner.


#!/bin/sh
nice -n 15 tv_grab_dk_dr --days 14 --out /home/mythtv/ud.xml 2>/var/log/mythtv/tv_grab_dk_dr_stderr.log
nice -n 15 mythfilldatabase --update --file 2 /home/mythtv/ud.xml > /var/log/mythtv/mythfilldatabase.log

Changing firmware for Hauppage WinTV MiniStick HD

I'm changing away from the firmware files here, to some obtained directly from Hauppauge http://www.wintvcd.co.uk/drivers/WinTV-MiniStick_4_2_10_27180_WHQL.zip.

Now I'll test and see if I get more stable tuning performance under MythTV/Ubuntu Karmic 9.10. I got the idea from here.

Detailed steps to change firmware file:

$ wget http://www.wintvcd.co.uk/drivers/WinTV-MiniStick_4_2_10_27180_WHQL.zip
$ unzip -j WinTV-MiniStick_4_2_10_27180_WHQL.zip  driver17/hcw17dvb.1b0
$ sudo cp hcw17dvb.1b0 /lib/firmware/sms1xxx-hcw-55xxx-dvbt-02.fw.WHQL_freebsd
$ cd /lib/firmware
$ sudo cp sms1xxx-hcw-55xxx-dvbt-02.fw sms1xxx-hcw-55xxx-dvbt-02.fw.org
$ sudo cp sms1xxx-hcw-55xxx-dvbt-02.fw.WHQL_freebsd sms1xxx-hcw-55xxx-dvbt-02.fw

Misc VDPAU changes

Hoping VDPAU in mythtv will be more stable on the Asrock ION 330HT.

Setting TripleBuffer true in xorg.conf.
Setting video memory size to 512 MB (in BIOS, old setting was auto.)

mpstat - monitor cpu load during video playback

I keep forgetting this great little tool. Indispensable for checking cpu load during video playback.

Sharing NTFS volume via smb.

1. Mount NTFS volume with umask=0222 (samba needs permissions to share drive)
2. Mount smb share with iocharset=utf8 (to get special characters to display properly)
