<f00bar80> why do VLC open this streaming URL http://24.148.122.144:7001/nphMotionHpeg?Resolution=320x240&Quality=Standard and a DirectShow filter can't <---- webcampxp ( IP Camera [JPEG/MJPEG] ) ? , i know that a DirectShow is meant more by file extensions, if this is the issue, how then VLC bypass it ? and if not may anyone thankfuly correct me ? or direct me to the right place in case i'm off-topic .
<Trax``> directshow is for accessing a capturecard/device not a http stream
<f00bar80> Trax``: cool , but the fact that this stream get played by VLC .
<Trax``> vlc using http:// as input works you mean?
<f00bar80> Trax``: yes
<Trax``> but you can't use vlc to get video from your capture device?
<f00bar80> Trax``: i'm mainly concernd with this URL, i want to know why it works in VLC and not the mentioned DirectShow filter /
<f00bar80> Trax``: or even want to know how it works in VLC ?
<Trax``> you can use the wizard to use a directshow device
<Trax``> and then transcode/stream
<f00bar80> Trax``: which wizard and what do you mean by directshow device
<Trax``> maybe one step back.. what do you want to do.. so far you say VLC opens a certain webstream.. but you want to know how directshow works
<Trax``> so what is your goal.. you plan to use directshow input on your capture device and use that as input for VLC and then transcode/stream to internet?
<f00bar80> Trax``: I want to use the webstream as an input to a directshow based application i.e. MSN messenger
<f00bar80> Trax``: did you get what i mean ?
<f00bar80> Trax``: in another meaning i want to use this webstream as a virtual webcam to my MSN messenger
<Trax``> yeah but I didn't get the relation to VLC .. it's just the input http that happens to work with it?
<f00bar80> Trax``: i'm asking about the way VLC uses to play this webStreaming , also if i can use VLC to transcode the stream to DirectShow device , if you mean by DirectShow ---> VFW based application
<f00bar80> Trax``: _DireShow Device ---means---> VFW based application_*
<f00bar80> Trax``: any comment ?
<Trax``> f00bar80: I don't think you can use VLC to create a vfw
<Trax``> vfw has also been deprecated and replaced by wdm drivers nowadays
<f00bar80> Trax``: which mean i can't use it to transcode the stream ?
<f00bar80> Trax``: always VLC can't transcode to wdm ?
<Trax``> you can use VLC to use input stream and restream or even retranscode but I don't see how you would use it inside applications like MSN
<Trax``> you could create a Windows Media Player compatible stream though, so people can connect to http://your_ip:8080/stream.asf
<f00bar80> Trax``: isn't MSN based on DirectShow Filters ? and i also see a lot of Virtual WEbCams , then how these cams are working
<Trax``> what you want is http stream -> VLC -> convert into directshow -> use in MSN
<f00bar80> Trax``: so no way even to know how VLC play this webstream ?
<Trax``> but VLC doesn't act as a transparant proxy thing to emulate a directshow device.. it can access a directshow device
<f00bar80> Trax``: any guide/pointer to VLC transcoding to Directshow ?
<Trax``> VLC cannot transcode to directshow.. see directshow as a low level driver for a capture device
<f00bar80> Trax``: and what i need is something to emulate directshow device ?
<Trax``> apparently if your application only accepts directshow as input such as MSN
<f00bar80> Trax``: then what do you suggest as something to emulate directshow device ?
<stevel> http://www.songbirdnest.com/merchtable ;-)
<zorglu_> stevel: hehehe :)
<Trax``> f00bar80: I don't know of any application that does that
<f00bar80> Trax``: is it this how a virtual webcam works ?
<f00bar80> Trax``: ...?
<Trax``> I don't know how virtual webcams work.. I do know a bit more about VLC
<f00bar80> Trax``: Only want to know what's the difference between something that emulate a directshow device and accessing a directshow device(VLC) , also what do you mean by ---> (_see directshow as a low level driver for a capture device_) ?
<Trax``> that what gives acces to a directshow device is a driver
<f00bar80> Trax``: i.e. ...?
<Trax``> VLC then uses that driver to grab raw input and can transcode/convert that
<Trax``> what you want is the other way around and VLC can't do that
<Trax``> VLC can't output to a directshow device
<Trax``> because that is typically an input device
<f00bar80> Trax``: what's meant exactly by a driver ?
<f00bar80> Trax``: also i'm still asking how VLC was able to play this webstream regarding this "Driver"
<Trax``> your first sample was just a webstream
<Trax``> and VLC can play those just fine
<f00bar80> Trax``: HOW ?
Trax`` is tempted to say "pure magic"
<f00bar80> Trax``: :) really i'm not joking :)
<Trax``> wouldn't know where to begin.. same as asking how (technically) windows media player is able to play a http:// stream
<f00bar80> Trax``: WMP is meant by file extension why not VLC ?
<Trax``> explain?
<Trax``> what do you mean by meant
<f00bar80> Trax``: WMP can't play http streams without file extension end
<Trax``> it can
<Trax``> for livestreams I never specify extentions
<f00bar80> Trax``: i tried to use WMP to play the mentioned URL , after installing/registering a filter for this streaming Cam , got the error "The media type of this file isn't recognized" after a time trying to get connected to this url
<Trax``> windows media only understands windows media
<Trax``> so if you use other types of codecs or hardware which produces incompatible streams for windows media player this can happen
<f00bar80> Trax``: even after registering a filter for this hardware ?
<Trax``> I wouldn't expect windows media player to be able to use an input device at all
<Trax``> it is meant for playing files not directly play from a capture device
<f00bar80> Trax``: so how VLC can do it
<f00bar80> Trax``: what's the difference that lets vlc play it and not wmp
<Trax``> VLC is so much more than just a player
<Trax``> it can use capture devices, convert/transcode/restream etc.
<f00bar80> Trax``: and to play webstream VLC use it as a capture device, or it convert/transcode this streaming to be displayed ?
<Trax``> transcode and restream is optional
<Trax``> I do that for a dshow device.. capture raw input, convert into H.264/AAC or WMV/WMA and stream through http
<f00bar80> Trax``: i'm talking specially regarding the URL i posted previously
<Trax``> that is just a basic http:// stream and what is done under the hood we don't know
<Trax``> VLC just reads it and decodes the video and audio just like WMP would and then displays it
<f00bar80> Trax``: so what do you suggest for me to do ?
<Trax``> never give up hope
<Trax``> and ask google :)
<Trax``> I have no idea how to do what you want.. perhaps there are tools out there that will make MSN use it as input
