The VideoLAN Forums

I've been playing around with the DirectShow input for VLC 0.7.0. I have a Canopus ADVC-1394 capture card that shows up as an OHCI compliant 1394 device to the operating system. Audio input goes through my sound card - a Creative SoundBlaster LIVE! 5.1. I am running Windows 2000 Advanced Server on a Dell PowerEdge 600SC Server, Pentium 4 2.4Mhz, 384Meg of RAM.

After hitting the refresh buttons, the DirectShow input screen sees the 1394 video device correctly (Microsoft DV Camera and VCR) and the audio device (SB Live! Audio [ECA0]).

However, when I click on OK, I get video but no audio. The following interesting message shows up in the message log:

main error: no suitable decoder module for fourcc `dvau'.
VLC probably does not support this sound or video format.

It seems that others have had similar problems with audio using the DirectShow inputs.

I would greatly appreciate any insights that anyone could provide.

Thanks,

kjo

I have similar problem. My sound card is integrated Digital SoundMax, the sound goes in through the line-in.

I'm also getting no suitable decoder module for fourcc 's16l'

Some people have success with transcoding the audio output. Why don't you give it a try.

regards.

Cool, first user reporting success (well partial ) with the dshow input and a DV (DigitalVideo) hardware!
Nobody had tested this yet so I didn't know if it was working

As for the audio problem, this is expected because 0.7.0 doesn't have a DV audio decoder anymore (this is why you have the message: "no suitable decoder module for fourcc `dvau' ").
DV audio used to be supported through the ffmpeg library but they recently dropped their support for it.
I'll try to fix that for the next release.

Just another note, in case of DV input, VLC won't use your soundcard audio input because the audio stream should be contained inside the DV stream.

To neotintinn:

"no suitable decoder module for fourcc 's16l' " happens when you try to stream your raw video/audio dshow input.
VLC just can't stream raw material (it wouldn't make much sense anyway as it would require enormous amounts of bandwith) so you have to enable the transcoding options.

Hi I got the sameproblem no sound output if i stream from my Hauppauge WinTV 350
Streaming DVD, Files etc. works verry well. Great work, by the way.I wish i can programm like you peoples.
P.S. Sorry for my misserable english. lol
I stream from my WinXP PC with a P4 3. Ghz Soundcard is on motherboard MB = ASUS P4G8X soundcard is Realtek ALC 650 6Channel audio codec to my Labtop.Dont know you need this data
Here My log from labtop as long i view the stream. Picture is perfect but no sound.

Maybe you professionals can help me

P.s. Sorry for my misserable english...

A small correction to my earlier post concerning my Canopus ADVC-1394 capture card . . .

My capture card takes in both video AND audio. The audio does NOT go through my sound card as I stated earlier. Sorry about the confusion . . . I don't know what I was thinking.

The ADVC-1394 takes in any analog Video/Audio source and presents it to the OS as OHCI-compliant Firewire Card connected to a DigitalVideo (DV) device.

Gibalou:

It is too bad that ffmpeg dropped their support of DV audio, but I'm glad to hear that you are going to try to add it into your next release. If you would like to test your BETA code in my hardware environment, just let me know.

Thanks,

kjo
