System will work the same in multiple operating systems. If people are currently using their systems with this codec they will need to swap their output ports. I have _not_ checked audio input or line input (basically, I have checked nothing other than line-out). I believe this is an appropriate change, it makes us consistent with documentation, and other operating systems. Furthermore, this feature (playing) is the vast majority of sound activities, so if this makes is right for playback and wrong for recording... playback is more important, and we can fix recoding in the future without worries of screwing people again in the future (since we'll be "right" on the playback). -- David E.

However, this problem doesn't occur in my Fedora Core 3 Linux skype with the same hardware. Neither does any other KDE sound application in my FreeBSD have any problem, even the clicking sound when using skype is ok. I wonder have anybody has found any solution to this problem.

It suports all the encoder interface, have a gtk2 grafic controler and v4l2 compatibility, but only works with YUAN or IO-DATA cards. I'm porting this driver for pvr250 (and pvr350 in next future), but I will need more dmesg and pciconf -lv of other cards for best support.

I can forsee at least one big obstacle in the bktr driver. it is necessary to call TVTUNER_SETTYPE before setting the tuner, even if you use TVTUNER_SETFREQ, which is quite different than V4L2. there are several bugs lurking in bktr. for example, why are the U saturation and V saturation ranges different? according to the datasheets they should be the same. also notice that on startup bktr reports a U saturation above the supposed limit! I'd much rather see the problems fixed than a shim added to it. how about working about multiple frame buffers? that's probably need for many V4L2 programs. IMO, it would be better (maybe even easier) to rewrite bktr with a V4L2 interface than to try to add V4L2 to it. but, IMO, the best thing would be to fix bktr and document it better. some bktr programs -> http://www.jakemsr.com/bsdav/bsdav-1.0.tar.gz -- From owner-freebsd-multimedia@FreeBSD.ORG Tue Apr 12 20:14:51 2005 Return-Path: Delivered-To: freebsd-multimedia@freebsd.org Received: from mx1.FreeBSD.org (mx1.freebsd.org [216.136.204.125]) by hub.freebsd.org (Postfix) with ESMTP id 8FF7316A4CE for ; Tue, 12 Apr 2005 20:14:51 +0000 (GMT) Received: from mail.vicor-nb.com (bigwoop.vicor-nb.com [208.206.78.2]) by mx1.FreeBSD.org (Postfix) with ESMTP id 2FFEF43D3F for ; Tue, 12 Apr 2005 20:14:50 +0000 (GMT) (envelope-from julian@elischer.org) Received: from [208.206.78.97] (julian.vicor-nb.com [208.206.78.97]) by mail.vicor-nb.com (Postfix) with ESMTP id D53457A403; Tue, 12 Apr 2005 13:14:49 -0700 (PDT) Message-ID: <425C2C39.8050607@elischer.org> Date: Tue, 12 Apr 2005 13:14:49 -0700 From: Julian Elischer User-Agent: Mozilla/5.0 (X11; U; FreeBSD i386; en-US; rv:1.7.5) Gecko/20050218 X-Accept-Language: en, hu MIME-Version: 1.0 To: Jacob Meuser References: <425C18A2.8010807@elischer.org> <20050412193149.GA15619@puff.jakemsr.gom> In-Reply-To: <20050412193149.GA15619@puff.jakemsr.gom> Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 7bit cc: freebsd-multimedia@freebsd.org Subject: Re: Anyone working on V4L2 for BSD?

There's on one hand the v= 4l2=20 framework and on the other hand there's a driver (in my case, it's a bktr=20 one) which registers itself at the v4l2 framework. Then, the latter creates= =20 the device nodes and the applications use these nodes to get in contact wit= h=20 the driver. Julian, I think that's what you are looking for, isn't it?

However I don't think I explained myself clearly enough. I know ho to author a video DVD, and can script that part simply enough. What I really needed to do is capture the video stream from the capture card and start the burn to DVD media immediately. The main problem I'm having is burn times. I would like the burn to be concurrent to the actual capture process, so all that's left after the capture is completed, is to fixate the disk, rather than re-encode, multiplex or any one of a hundred other things that need to be done for a video DVD. Something like cat /dev/cxm0 | growisofs -Z - would be ideal, but I don't know if or how well it would work. Does anyone have any experience with this?

If you want you can compare the output of dd (output blocks should be similar to 143618) or check its error code or look for unusaly output... Bye Arne __________________________________ Yahoo!

I think this is the wrong idea. This is a class driver so *all* devices should be supported.

The X11R6 Xvideo interface (about which I know very little) and V4L(2). There is however a shim that allows Xvideo to talk to L4V so I think we should look at making hte devices L4V compliant.

It's API is still years behind what we should have... The reason I haven't said anything is that I didn't want to attempt to derail any work that someone might be doing.. Yes, V4L2 is not a very good api, but as others have pointed out, it makes portability easier... Plus, I haven't spent any time on VideoBSD recently, since I've gotten sidetracked by other projects... (Though if I can get ATI to give me specs for their HDTV PCI card, I might spend some more time on it...) So, if you just want Linux compatiblity, go for it...

Think "netgraph for video" with a V4L2 frontend for apps and a v4l2 backend for drivers. The difference is that the framework would interpret all the ioctls etc instead of the drivers themselves. The drivers MAY attach using a V4L2 interface, but the requersts they get MAY or MAY NOT have come from the clients. In the middle we have support for modules that do simple format conversion, resynching, snipping, and the ability to pass the stream out to a userlandeditor and get it back again, for really compilcated editing.

Earlier Releases needed to configure device pcm device snd_sbc for this card. But now it is neccessary to configure device sound device snd_ess device snd_sbc "device sound" replaces the former "device pcm", but now "device snd_ess" is also needed. If only the former two drivers are included, then the card will be detected, but the "sound" driver will not see the card and no device nodes get created. When loading runtime modules, only "snd_ess.ko" is necessary, and will automatically load the other two.

But: does *any* device work yet? Read: has someone fixed the 0x3fff Problem yet (I have local patches, so it works here)? I'm not up-to-date with my -current sources (everytime I want to update, someone breaks something and I don't update...) and I don't have enough time to be up-to-date with reading cvs-all, so I don't know if you've already committed your previous patches which improved the uaudio support. BTW.: Since only 3 people seem to have an uaudio device, run -current *and* read this mailinglist, I think you can commit any code which works for you without the need to call for review here. Most likely there are only minor glitches and we can moan loud enough if it breaks for us... ;-) Bye, Alexander. -- http://www.Leidinger.net Alexander @ Leidinger.net: PGP ID = B0063FE7 http://www.FreeBSD.org netchild @ FreeBSD.org : PGP ID = 72077137 I exist, therefore I am paid.

I'm removing the DMA mem allocation in the PCM layer. The uaudio driver does it's own buffer allocation (though I don't think it's dma capable at that layer, but when it is...) It's bad that we have to do so many copies but we can't just easily rewrite the uaudio driver. --Mat -- From owner-freebsd-multimedia@FreeBSD.ORG Thu Apr 14 17:20:55 2005 Return-Path: Delivered-To: freebsd-multimedia@freebsd.org Received: from mx1.FreeBSD.org (mx1.freebsd.org [216.136.204.125]) by hub.freebsd.org (Postfix) with ESMTP id AEEDB16A4CE; Thu, 14 Apr 2005 17:20:55 +0000 (GMT) Received: from postal1.es.net (postal1.es.net [198.128.3.205]) by mx1.FreeBSD.org (Postfix) with ESMTP id 6F77343D3F; Thu, 14 Apr 2005 17:20:53 +0000 (GMT) (envelope-from oberman@es.net) Received: from ptavv.es.net ([198.128.4.29]) by postal1.es.net (Postal Node 1) with ESMTP (SSL) id IBA74465; Thu, 14 Apr 2005 10:20:53 -0700 Received: from ptavv (localhost [127.0.0.1]) by ptavv.es.net (Tachyon Server) with ESMTP id 14E685D07; Thu, 14 Apr 2005 10:20:52 -0700 (PDT) To: Alexander Leidinger In-reply-to: Your message of "Wed, 13 Apr 2005 14:31:26 +0200." <20050413143126.7e0jufn80c0cwow4@netchild.homeip.net> Date: Thu, 14 Apr 2005 10:20:51 -0700 From: "Kevin Oberman" Message-Id: <20050414172052.14E685D07@ptavv.es.net> cc: jmg@freebsd.org cc: FreeBSD Current cc: Julian Elischer cc: multimedia@freebsd.org Subject: Re: Anyone working on V4L2 for BSD?

FreeBSD being limited to various forms of Brooktree video chips is a serious limitation in this day and age. I routinely have to tell people who want to use our H.323 conferencing system from a laptop that they are OOL. :-( And even desktop users are annoyed that they can't use their (already purchased) USB cameras and that they have to get a camera with video output and a WinTV card. Of course, I am still fighting a battle with getting recent GnomeMeeting to work on V5, but I do make a bit of progress on this from time to time when I have a chance to work on it. -- R.

The low hardware layer already does DMA to move data out of the hardware to memory. The data gets copied from the user layer to an intermediate buffer and from there to the DMA buffers. There is no need to allocate DMA capable buffers for the intermediate layer. > > Bye, > Alexander. > From owner-freebsd-multimedia@FreeBSD.ORG Fri Apr 15 03:33:50 2005 Return-Path: Delivered-To: freebsd-multimedia@freebsd.org Received: from mx1.FreeBSD.org (mx1.freebsd.org [216.136.204.125]) by hub.freebsd.org (Postfix) with ESMTP id 75D8B16A4CE for ; Fri, 15 Apr 2005 03:33:50 +0000 (GMT) Received: from burrito.bitsurf.net (dcn235-229.dcn.davis.ca.us [168.150.235.229]) by mx1.FreeBSD.org (Postfix) with ESMTP id 08FF743D3F for ; Fri, 15 Apr 2005 03:33:48 +0000 (GMT) (envelope-from mharo@bitsurf.net) Received: from burrito.bitsurf.net (localhost [127.0.0.1]) by burrito.bitsurf.net (8.13.1/8.13.1) with ESMTP id j3F3ZxA5074588; Thu, 14 Apr 2005 20:35:59 -0700 (PDT) (envelope-from mharo@bitsurf.net) Received: (from mharo@localhost) by burrito.bitsurf.net (8.13.1/8.13.1/Submit) id j3F3Zxiu074585; Thu, 14 Apr 2005 20:35:59 -0700 (PDT) (envelope-from mharo@bitsurf.net) X-Authentication-Warning: burrito.bitsurf.net: mharo set sender to mharo@bitsurf.net using -f Date: Thu, 14 Apr 2005 20:35:59 -0700 From: Michael Haro To: Julian Elischer Message-ID: <20050415033559.GA74522@bitsurf.net> References: <20050412064056.GA24914@bitsurf.net> <425C0F44.10407@elischer.org> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline In-Reply-To: <425C0F44.10407@elischer.org> User-Agent: Mutt/1.4.2.1i X-Operating-System: FreeBSD 5.3-RELEASE-p1 X-SMTP-From: localhost [127.0.0.1] (burrito.bitsurf.net) X-Scanned-By: MIMEDefang 2.49 on 168.150.235.229 cc: freebsd-multimedia@freebsd.org Subject: PVR-150?

I understand this as: userland-mem -> kernel-mem -> dma-able-mem -> hardware So there's no zero-copy behavior? userland-mem -> in-kernel-dma-able-mem -> hardware or userland-mem -> if(is_dmaable(userland-mem)) -> hardware else -> in-kernel-dma-able-mem -> hardware While the amount of memory used as a sound buffer isn't that much for todays standards, it's still a memory transfer operation which could be avoided. I don't know how much it would affect the latency (or if it affects it at all), but not doing things which aren't necesssary/beneficial is always a win (in some way) in my experience.

So this means it isn't counter productive when we remove the DMA code from uaudio, since it has to be allocated at another place if we want to move to a zero-copy design?

This doesn't seem to be working for me. The analog output seems to be working at all times, but the digital is quiet. I know I have the cabling right, this exact same setup worked under Linux. I guess, just to prove it works, I will go ahead and load the OSS drivers, but once I get digital output, I'm going to be back here. I want digital output. I'm searching for documentation on the web, for how the mixer function works. I figure that's the section of code that allows or disallows the digital, but I am getting the idea that it's all done in dsp code, so it might be a bit less cut & dried than I might like it to be.

I have tried messing around with the xmms equalizer with no luck. I thought it might have been my sound card/ speakers so I swapped it for the same card that was in my other box and even swapped the speakers. This didn't help either.. This is how I load the drivers for my sound card: A. I added snd_emu10k1_load="YES" in /boot/loader.conf B. Also kldstat shows this : 3 1 0xc0af6000 7dbc snd_emu10k1.ko 4 2 0xc0afe000 218dc sound.ko C.

Earlier Releases needed to configure device pcm device snd_sbc for this card. But now it is neccessary to configure device sound device snd_ess device snd_sbc "device sound" replaces the former "device pcm", but now "device snd_ess" is also needed. If only the former two drivers are included, then the card will be detected, but the "sound" driver will not see the card and no device nodes get created. When loading runtime modules, only "snd_ess.ko" is necessary, and will automatically load the other two.

AFAIK the only documentation for EMU10K1 is driver source code for Linux. And the code is full of magic constant and its microcode. It's really hard to understand internal architectures and DMA etc. Without more information from Creative it would be hard to fix/enhance current emu10k1 driver, IMHO. Of couse, Creative says they released all necessary PCM programming information for their EMU10K1 products. :-( -- Regards, Pyun YongHyeon http://www.kr.freebsd.org/~yongari | yongari@freebsd.org
