Embed Subtitle into Output VDO with AviSynth

If you want to embed *.srt subtitle into output VDO by using AviSynth:

1. Download VSFilter from http://www.animereactor.dk/aegisub/
2. Extract vsfilter.dll to folder C:\Program Files\AviSynth 2.58\plugins\
3. Add these commands into *.avs file:

LoadPlugin("C:\Program Files\AviSynth 2.58\plugins\VSFilter.dll") TextSub("filename.srt")

If audio and video are not sync'ed together, use these commands to split them, and then adjust audio delay.

V = DirectShowSource("video.mp4",fps=25.0,convertfps=true) A = DirectShowSource("audio.aac", video=false) AudioDub(V, A) DelayAudio(-0.500)

Power Amp Class-D (part 2)

I went to Baanmooh today gain.
At first I am going to buy two of Power Amp Class-D 20W
But I saw this, Power Amp Class-D 12+12W, 690 BHT.

12W+12W CLASS D Specifications 1. 12W/CH, 8 Ohms Load at 15 Vcc 2. No Heatsink 3. 32 Step DC Volume 4. Vcc 8-18 V 5. Imax 2 A at Po 12 W 6. Shutdown 160 uA

It uses digital volume control to adjust both level simultaneously.
So there will be no noise generated when the volume got dirt.

No pop/click sound generated when turning on/off power switch.
(The same as 20W.)

I have measured its power consumption:
- No sound, 15 mA
- Playing at normal level, 25 mA
- Driving SubWoofer speaker, 125 mA

Modify Car MP3 Player (part 2)

Oops! I did it again... errr... I mean I bought it again.

A Car MP3 Player, 220 baht, with a new circuit design. (But the same crap sound quality)
So I added an antenna and 2 capacitors to add more treble.
Now its sound quality is better than some radio stations. ;-)

- Antenna, use thin wire about 36 cm. long.
Then soldered at ANT label.
(I forgot to take the photo)

- Use 2 small 0.0068uF capacitors, then soldered into the space as shown in photos.
(I found only the big one from my spare)

- Use cutter to cut the plastic filter between LCD display and infrared receiver.
(Don't know what's that filter for)

Modify Windows Vista to obtain IP address automatically

To resolve this issue, disable the DHCP BROADCAST flag in Windows Vista. To do this, follow these steps: 1. Click Start, type regedit in the Start Search box, and then click regedit in the Programs list. 2. Locate and then click the following registry subkey: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{GUID} In this registry path, click the (GUID) subkey that corresponds to the network adapter that is connected to the network. 3. On the Edit menu, point to New, and then click DWORD (32-bit) Value. 4. In the New Value #1 box, type DhcpConnEnableBcastFlagToggle, and then press ENTER. 5. Right-click DhcpConnEnableBcastFlagToggle, and then click Modify. 6. In the Value data box, type 1, and then click OK. 7. If the DhcpConnForceBroadcastFlag is 1, double-click and modify it to 0. 8. Close Registry Editor. By setting this registry key to 1, Windows Vista will first try to obtain an IP address by using the BROADCAST flag in DHCP Discover packets. If that fails, it will try to obtain an IP address without using the BROADCAST flag in DHCP Discover packets. MORE INFORMATION If you know the router or the non-Microsoft DHCP server does not support the DHCP BROADCAST flag, you can set the following registry entry as follows instead of using the DhcpConnEnableBcastFlagToggle registry key. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{GUID} Value name: DhcpConnForceBroadcastFlag Value type: REG_DWORD Value data: 0 Note A data value of 0 disables this registry entry. You can use this registry entry to prevent Windows Vista from using the DHCP BROADCAST flag. After you set this registry entry, Windows Vista never uses the DHCP BROADCAST flag.

How to get GUID value? 1. Click Start, type cmd, press Enter. 2. type ipconfig /all, then look for Physical Address of your adapter. 3. type getmac, then you'll get the Transport Name as GUID value.

But if the IP address is still unable to be obtained, the only way to do is to fix IP address, Gateway, and DNS address in Windows Vista.
