VB Tuner Example

**NiN^_^NiN** · 09-06-2007, 08:52 PM

Hey guys

I was searching through my files yesterday and i found some old software i made for myself for the TV tuner i had

I now have a external standalone unit i got cheap so i don't use it anymore

Would this be handy to anyone out there?

I seem to only have the very basic version when i first started so it's just the video and a button.

Very simple code only downside is the user has to manually find the settings for each channel

What i did was i used VLC player as a plugin on the VB form and loaded up a MRL string for each channel

I had the button load up the MRL string to the componet to change channels.

the MRL string is made up when you select what device you want and what channel you want in VLC

Example is here the top part is the MRL string

Would this be useful for anyone? this can also be used for webcam recording aswell or video playing

I had it setup on mine with 5 images along the bottom of the screen which was the logo of each tv station and had the MRL settings for each station. I just used a jpg as the background image to have it blend into any frontend i used aswell.

So is this helpful to anyone?

I would like to see the source, most definitely.. seems like fairly interesting way of using VLC (which I never thought could handle TV).

Oh yeah i use VLC for recording webcam aswell using a MRL command to preview and save the video at the same time with mp4 codec it's quite a handy tool if you know the inner functions.

It has 2 buttons 1 is for my webcam (i don't know where my tv tuner card is so i used the webcam to test if it still worked)

and the other just loads up a avi file on C drive

This is an example of a MRL

dshow:// :dshow-vdev="USB PC CAM-168":dshow-adev="" :dshow-size=""

Thats just to show the Webcam

To get the MRL for TV Channels you need to of course download VLC first i gather u have already

Open up VLC
File > Open Capture Device

You need to Select the Video capture device in Video Device Name

You then click Advance Options

Now all you need to so is select the proper TV channel country code tuner input (cable or antenna) and the video/audio pins

Click ok and then you can copy the MRL out of the customize dropdown box and insert into the VB program

It is very simple but it is also not very setup friendly altho you do have the MRL with the settings you could make a setup program in VB that changes the channels etc to you find a source and then save it.

But as i said on mine i just found the channels then saved the MRL to the TV stations logo cause once i had it set i didn't need to reset it.

Also if you would like to play with it as a webcam saver you can check the Stream/save box as in the first image then click settings

just have to click play locally and file with a filename then select the video and audio codec and you will have a new MRL

You can PM me if you want any help or questions about VLC properties I hope this is useful for you

Oh i also forgot sometimes the software that comes with the TV tuner can screw up VLC being able to use the TV card this is cause of the auto tune feature you just need to reinstall the tv cards software and don't run it that will fix any problem you could find with the tv card not working
