Hi,
I am using a ATI TV Wonder 650 PCI for capturing live TV content to stream
using FME 2.5. I am able to stream the video, but there is no Audio. when I
choose ATI AVStream Analog Audio Capture, it does not seem to populate the
sample rate and hence there is an error.
Now I am able to get Audio in another way, here I open up another
application which shows the Live TV, and all of a sudden FME voice bar shows
activity. And streams Audio. The problem here is The Audio is slower than the
video when I start streaming, so they are not in sync.

Any Ideas where could be the issue.

Thanks

Changing the codec (nelly/mp3/aac) might populate the sample rate dropdown,
because different sample rates are supported for different codecs:
mp3: 11025, 22050, 44100
aac: 8000, 11025, 22050, 32000, 44100, 48000
nelly: 8000, 11025, 22050, 44100

For the sync issue, can you please further elaborate. what exactly are you
trying to do. Can you list out exact steps and attach log file?

Thanks for the reply.

There is nothing showing other than MP3 and the Sample Rate field is empty. I
tried making changes to the profile xml file thinking it will make any
difference, but it did not.

As for the sync Issue. I choose ATI Av Stream Video Capture for Video and my
on board Realtek Audio. Now the Audio does not come up, until I open up another
application the "Catalyst Media Center". Now with both my encoder and Catalyst
Media center open, I can start streaming. However I see that the Video comes up
as much as 2 seconds earlier than the audio. I am assuming this has something
to do with Encoder taking the audio from my mixer rather than directly from the
capture device. (Will post the log in my next post)

There may be a clue in the statement "all of a sudden FME voice bar shows
activity. And streams Audio" along with "ATI AVStream Analog"

I had a very old TV card (not this model though) for which the audio driver
was non-standard. Audio was only sent to the sound card when the provided TV
application was running, and there were no updated drivers for my OS.

My understanding is this was done because of Audio sync issues over the
limited bandwidth of the PCI bus.

The idea that AVStreamAnalog is available suggests the device may be doing the
same thing - sending *only* video through a regular, system accessible hardware
driver, and audio is routed only to the sound card - that is, it doesn't appear
as a capture device (though the sound card will, obviously)

I guess the acid test would be to try this in another program - for example
windows media encoder - to see if the device configuration / property page is
available, or if it too shows no audio sample device for that card.

Analog TV cards are very cheap, so grabbing a replacement should be pretty
simple to test with.

I am currently using this ATI 650 Pro card for Streaming Live content using
Windows Media encoder. But when I try the Adobe encoder it seems to give all
kinds of issues. I also checked and saw that I have all latest drivers. Since I
am streaming video content, think I will now have to get a new TV Tuner card,
are there any recommended ones? Ones that don't have any issues of running
continuously and unattended for application errors etc.

Thanks

TV Tuner cards do the opposite of Broadcasting. You will need something that
spits out media (a video camera, a dvd player etc.).
If you bought a 1,000.00 TV tuner card-you would still not have anything
coming out as a Broadcast. They are made to do something different, to receive
a Broadcast....This drove us crazy for about a month. After umpteen million new
and used cards, we decided to start our own field testing and started chewing
on every option that came to mind. One day all the magic worked..........

Ok, in your terms, what I am doing is re-broadcast. I have a TV channel which
my client wants to be web streamed. So is there anything other than a TV tuner
which does a tuning to receive a satellite channel?
