[02:29] <jlewin> Hi all, running Windows and the lastest build of ffmpeg. Attempting to switch from UScreenCapture to screen-capture-recorder but having problems with the crop filter; it crops to the target size but then scales to the source resolution. Any thoughts or tips appreciated.
[02:52] <jlewin> Well, it looks like crop followed by scale achieves the results I was looking for. Not sure if it's the best approach but it seems to be working
[02:52] <jlewin>  -vf "crop=1024:576:295:161,scale=1024:576"
[03:45] <Technicus> Hello, I am looking for some help with a < http://www.startech.com/AV/Converters/Video/HDMI-to-ExpressCard-HD-Video-Capture-Card-Adapter-1080p~ECHDCAP >.  It is a very messed up story.  I found this device yesterday and it was listed on the StarTech website as having Linux support.  So I ordered it with overnight delivery, it showed up before I was even awake.
[03:45] <Technicus> After work, I started messing with this device.  The instruction manual has only one reference to Linux, "Compatible Operating Sustems Linux kernel 2.6.14 or later".  I could not find any tutorials, forums or examples of how to interact with this device.  I am competant with Linux, but I've never messed with a video capture device before.
[03:45] <Technicus> So I called the technical support line.  I was informed that Linux support has ended and there was no assistance to be offered, other than a full refund to include shipping charges. LAME!  Even though the instruction manuel that came with the device in the box indicates Linux support, they refuse to honor their claims.  WEAK!  The tech support explained that since there is a new revision I can't be helped.  Check out the different versions of the manua
[03:45] <Technicus> l page 7, which is 10 of the pdf:
[03:45] <Technicus> Manual Revision: 12/19/2011 < http://mediapool.xpressplatforms.com/product-files/pdf/816359-36545.pdf >; Manual Revision: 05/15/2012 < http://sgcdn.startech.com/005329/media/sets/ECHDCAP_Manual/ECHDCAP.pdf >.
[03:45] <Technicus> Yesterday when I found this device it was listed on the StarTech website as having Linux support, today it does not.
[03:45] <Technicus> Will someone please help me to determine if I can get this device to cooperate with Linux, or direct me to a channel that would be more approporate for this discussion?  Thanks.
[03:47] <sacarasc> You'll probably need a kernel module driver thing.
[03:49] <Hello71> do other expresscards work?
[03:49] <Technicus> sacarasc: lspci reports the card as: "06:02.0 PCI bridge: PLX Technology, Inc. Device 8603 (rev aa)"
[03:49] <Hello71> and I thought you wanted a usb device
[03:50] <Technicus> Hello71: I was looking for usb devices until I found this, and StarTech had it posted with Linux support.
[03:50] <Hello71> lspci -vv -nn -s 06:02 | wgetpaste
[03:50] <Hello71> or sprunge or whatever
[03:51] <Technicus> I would not have purchased it had it not been described as having support.
[03:52] <Hello71> I wouldn't trust manufacturers on this
[03:52] <Hello71> 21:50:42 < Hello71> lspci -vv -nn -s 06:02 | wgetpaste
[03:53] <Technicus> Hello71: <  http://bpaste.net/show/415150/ >
[03:54] <Hello71> that's a... PCI bridge?
[03:55] <Hello71> delete -s 06:02
[03:55] <TiZ> What's the most efficient way to add a background image to a video that is comprised of an x11grab capture and a v4l2 capture in opposite corners of the screen?
[03:56] <Technicus> Hello71: < http://bpaste.net/show/415160/ >
[03:57] <TiZ> I tried -i background.png and all the framerate kludges and input order kludges to make it adhere to the rest of my sources, but it ended up being way more taxing than just padding and leaving the background black, and if not that, it caused the x11grab to get REALLY choppy.
[03:58] <Hello71> Technicus: what distro?
[03:59] <TiZ> Here's my current ffmpeg command line: http://pastebin.com/k2yFBSNf How would I modify it to add a nice little background image without messing up my other inputs or synchronization, and without incurring too much extra CPU cost?
[03:59] <Technicus> Hello71: Arch Linux
[04:00] <Hello71> Technicus: #archlinux can probably help you better; barring that, ##linux
[04:00] <Hello71> although I'd recommend against the latter.
[04:01] <TiZ> ##linux isn't usually very useful. And often straight up hostile toward Arch users.
[04:26] <Technicus> TiZ: Most channels are hostile.
[04:28] <sacarasc> TiZ: -loop 1 -i foo.png maybe?
[04:30] <TiZ> sacarasc: With that, it forces the framerate to 24 fps.
[04:30] <sacarasc> TiZ: -loop 1 -r 60 -i foo.png maybe?
[04:30] <sacarasc> Oh, you're using -r 30
[04:30] <sacarasc> That, then!
[04:32] <TiZ> That... kinda works? It's at 29.
[04:34] <TiZ> Normally, I can get 30 FPS no problem. With -loop 1 -r 30 -i foo.png, and filters adjusted accordingly, I get 29 FPS. :|
[04:34] <TiZ> It also makes no difference what image format I use.
[04:35] <TiZ> http://pastebin.com/Rjet2qCR is what I've got right now.
[04:36] <sacarasc> Only 1 thread?
[04:36] <TiZ> Trying to keep it from stressing games.
[04:36] <TiZ> I'll bump up to 2 and see if it makes a difference.
[04:55] <TiZ> sacsarasc: 2 threads makes it work out... but then I put it in the script that's generating the command and then it gets choppy :/
[06:57] <Technicus> Back to the drawing board, check this thing out: < http://www.epiphan.com/products/frame-grabbers/dvi2usb-3-0/ >.
[07:21] <agentorange> hi so does anyone know why Im getting "missing picture in access unit with size ..."

[11:28] <Filarius> Hello, under Windows OS I use Livestreamer to record RTMP streams. Often I have issue with recorded files - players (VLC too) do not see video stream or codec (VLC show error "*undef* video codec"), and ffmpeg too "Stream #0:0: Video: none". I found I can fix files with Avidemux(at last to see some part), but I can`t find this software good for processing many files. I wonder how I can use
[11:28] <Filarius> FFmpeg or else software to fix so files.

[11:57] <kippi> Hi
[11:58] <kippi> I long time ago someone helped me with building a ffmpeg command that worked out motion, it was a lovley one liner using motion filter, is there any way I can search the archives for this command
[15:17] <Dae> Hiya. Does anyone know how you could use ffmpeg to find the "loudest parts" of a video? i.e. with a given input video, output a clip of footage where the audio stream amplitude was over a given threshold?

[20:06] <Reventlov> Yosh.
[23:48] <dahat> Any chance someone knows of an idiot proof guide to building FFmpeg under windows with the VS2013 toolchain (and MiniGW if need be))? ... as apparently, I'm a pretty good idiot in this case.
