Hello, The title might be a bit confusing but here's the problem. When I open a VLC instance (VLC 3.0.3, 3.0.4 or 2.2.8 ), it consumes a certain level of CPU. However, when I open multiple VLC instances, the CPU usage increases for each VLC players. Let me explain with an example: * I launch first V...

Hi Remi, I think there is a misunderstanding. I just tried this scenario in VLC 3.0.3 and it works. Please check this image out. https://imgur.com/a/XSN4UzT Basically I have an input source and two PCs. Lets call them PC1 and PC2. PC1 has two ethernet adapters. * The input source is coming from udp:...

Hey wrybread, I kinda solved this. You can check my solution on https://forum.videolan.org/viewtopic.php?f=32&t=146788 Basically you need pcap library in combination with a single VLC instance. Use VLC instance just to display the media, and bind pcap udp socket to the incoming media stream port...

Hi Remi, By design, output controls cannot apply to stream output. It does not work in the VLC media player either. I just tried this again using VLC 2.2.8 and it actually works from the GUI. This is the steps I followed; 1. Connect two PC on the same network. Let's call them PC1 and PC2. 2. Open VL...

Hey guys, I tried doing this as well recently and it turns out this is not currently supported by vanilla libvlc 3. You will need to patch. An alternative way I've been suggested is to use an additional mediaplayer in the background which only does sout (no display). Hey mfkl, I already tried this ...

Yeah, sorry for the poor explanation. Basically what I am trying to say is that, I can control the audio level of a media using "libvlc_audio_set_volume". However, if I duplicate the media, for example; :sout=#duplicate{dst=display, dst=std{access=file,mux=ts,dst=save.ts}} I can no longer ...

Hello everyone, I can control audio level of a media using "libvlc_audio_set_volume" function. However, once I duplicate the media as given with the code below: :sout=#duplicate{dst=display, dst=std{access=file,mux=ts,dst=save.ts}} I can no longer change the volume by any means. I want to ...

Hello everyone, I have Qt application which allows users to watch a stream, and record this stream if needed.The interface looks as follows; https://imgur.com/a/CGB8vP7 So "Open Stream Button" allows user to watch a specific stream and "Record Stream Button" displays and record t...

Ok.. Is there any way to catch resolution changes? I've looked at libvlc_event_e struct but I couldn't find anything useful. How does VLC Interface show "Display resolution" information in Tools-->Codec Information-->Codec tab. Does it use timer, constantly checking for media resolution or...

Hey JB, I cant get the log messages for the moment crash occurs since VLC kind of closes itself without giving crash window warning (There is no 'Force to Close' window). But here is what the log looks like right before the crash: https://files.fm/u/aaurr225 Also here is the crashdump file: [version...

The stream is evidently corrupt, possibly due to packet loss (though that's not an excuse for VLC crashing.) Exactly. The streaming process is through air, so packet losses are very common. Do you think I can minimize the number or times VLC crashes due to corrupted input? (Using VLC 2.2.5.1, night...

Hi there, I have .ts file and I tried to open it using VLC 2.1.5 first and VLC crashed. The log messages right before crash looks like in the image below; https://pasteboard.co/GQPjDiK.jpg The problem with my .ts file is that there are some parts that display resolution changes rapidly. Normally vid...

Hi there, I'm trying to stream a video source to a Unicast address using VLC. So far what I've tried is; :sout=#udp{mux=ts,dst=192.168.20.10:1234} :sout-keep This works just fine but ONLY if destination address is valid. In other words, if there is no connection to 192.168.20.10 address, vlc.exe mem...

Hello, I'am using VLC 2.2.5.1 API in my QT program. I have a .ts stream and I am opening it using libvlc API where I would like to show media information just like Tools->Codec Information->Codec tab in VLC interface. My code is as follows; libvlc_media_track_t **tracks; libvlc_media_stats_t stats; ...

Hi there, I'm trying to merge multiple video files using Qt and libvlc. I can achieve this using 2.2.6 Vlc command prompt as; vlc input1.ts input2.ts :sout “”#gather:std{access=file,mux=ts,dst=output.ts}"" :sout-keep However I couldn't find a way to do this using libvlc api. There is a &qu...

Hi, I'm developing a Qt application which provides users to watch up to 4 different videos simultaneously. I'm using libvlc api for playing media. Anyway, what I'd like to do is to print vlc logs for each specific player. Same as Tools->Messages and you can view the whole log in the console. So far ...

Hi there, I know this discussion is out there for a while but is there any progress on recording the streaming video on the fly with libvlc API? Basically what I'm trying to achieve is display and record an incoming video stream. Currently, to record the streaming video; QString option1 = ":sou...

Hi forum, I've solved this particular problem a while ago, in case you wanna mess with the rtp g711 packet size, heres how you can start with: In ..\vlc\modules\codec\avcodec\audio.c, check for SplitBuffer function. The line; p_sys->p_samples += i_samples * p_sys->p_context->channels * ( p_dec->fmt_...

Sorry Sébastien, it took me a while to investigate thru the logs. Well, there is only 1 more URI that the client side requests from the server, that is a dll request named "DVRobot.dll". The request is something like Expert Info (Chat/Sequence): GET /manifest/DVRobot.dll HTTP/1.1\r\n So i ...

look at the source of the page in the browser, and look for the real url of the stream it opens. made a quick check and this is the whole source of the webpage i can access; <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <h...

Hi forum, I have two different DVRs with a IP camera connected as input. I am able to monitor the camera's input on another PC using an internet browser(IE, mozilla both works) by simply typing the device's configured IP addr, such as; http://xxx.xxx.xxx.xxx. The wireshark log also confirms the pack...

I've tested this on a SIP phone and it didnt raise an issue.This seems like a display bug on vlc side. Try adding "audio-sync" to your transcoding parameters.

i've had a similar problem. For some reason the codec info shows the double amount of fps value. But i dont know if this is the case or just a display bug or maybe something to do with your/our settings.

VLC uses 64-bits microseconds timestamps. OK, leave out the negative values so 63-bits only. That should cover almost 300 millenia. There may of course be a bug somewhere. Ok but the .dlls im using are compiled for win32 by following http://wiki.videolan.org/Win32CompileMSYSNew since i couldnt find...
