#rtp causes the same amount of workload as #udp.

Sorry for not answering for such a long time. I was in another town, but now I can do some tests again until the weekend. Replacing "#udp" by "#http" resulted in a cpu load between 5 and 10 percent - just the same as #file. I guess the reason for the high load must be in some udp...

Thank you for spending time on my post anyway.

I found out, that the main load must be caused by the network-component. When I replace sout=#udp{...} by sout=#file{mux=ts,dst="sample.ts"} VLC reduces its cpu consumption from 50-60% to 5-10% of both (virtual) cores.

If it helps, here's the log with verbosity level 2: main debug: processing request item dvb-c://frequency=370000000 node Wiedergabeliste skip 0 main debug: resyncing on dvb-c://frequency=370000000 main debug: dvb-c://frequency=370000000 is at 0 main debug: starting new item main debug: creating new ...

Hi, I'm streaming some video from an old computer (Intel Pentium 4, 3.0 GHz + HT, 512 MB RAM) to some other computers in my LAN (or sometimes to the localhost-address). This is how the command-lines look like: vlc.exe dvb-c://frequency=370000000 :dvb-modulation=256 :dvb-srate=6900 :dvb-network-name=...

When you're streaming video from the computer with the digicam via RTP on port 5004 (for example), you can easily receive it on the target computer by pressing CTRL+V and typing "rtp://@:5004". To be more specific, you could also type something like "rtp://@192.168.0.4:5004", if ...

To display the video, you will need some software on the receiving devices. For example, you could run VLC on the receiver devices and press CTRL+V to type the network address.

Hi! I want to stream some video with VLC over the internet and other networks with high packet loss rates. Since there seems to be no FEC support until now, i thought it might be a good idea to stream the data through a TCP-tunnel and buffer a few seconds on the receiver side. I implemented the foll...

I didn't success with sound because I didn't try it. The only task of the computer, which I configured here, is to multicast the video- and audio-data to the local network (using --sout). Did You try to stream whole transponder? Well, I tried it, but always failed. I'll try again with vlc 2.x when i...

It would be very useful, if there was a possibility to give vlc alternative parameters for receiving from a dvb-adapter (by command line). This would help users who only receive a poor signal. Here is an example: You type something like vlc dvb-c://frequency=658000000 :dvb-srate=6900 :dvb-modulation...

Sorry, but i have to contradict. I always use dvb-srate=6900 and it works perfectly with dvb-c. Seems like vlc wants a value in kBd, not in Bd. Still, it's worth verifying that the used value is correct.

Looking at the GDB-output, i was wondering why the log talks about "wined3d". I know Wine is used on Linux systems to simulate WinAPI functions. If i remember correctly, VirtualBox also uses Wine to simulate DirectX API functions. So I got the idea of changing the video output method from ...

Okay, this is the first time I used the GNU Debugger by command line. This is my output: Reading symbols from C:\Dokumente und Einstellungen\Administrator\Eigene Dateien \vlc-2.0.0-rc1\vlc.exe...(no debugging symbols found)...done. (gdb) run Starting program: C:\Dokumente und Einstellungen\Administr...

Okay, I (re-)downloaded "vlc 2.0.0-rc1 Twoflower" version from http://download.videolan.org/pub/testing/vlc-2.0.0-rc1/win32/ . I'm not sure, whether this is the same version as "vlc-2.0.0-rc1-20120205-0203". I tested it both on Windows Vista and on Win XP. Here is the result: Vis...

I have more or less the same problem. Can you explain how to make vlc stream every channel on an own port? That would be very nice

I think you need to create a DVB-C tuning space under Windows. This is how i managed to get it work: viewtopic.php?f=14&t=90961

Thank you for the link. Multiupload.com is currently not working but at least it gave me links to other filehosters. So here is the file:

I downloaded vlc 2.0 rc1 and it still crashes with the new file. The old file doesn't make it crash but I only see a black picture instead of the video.

Okay, now i realized that ffplay is a player and not a codec. So I downloaded and tried it. As there seems to be no option to speed up the playback in ffplay, I created a new, more complex ffv1 file which makes vlc crash even with 1.00x speed. (It has peak bitrates of > 180 MBit/s.) The Result: ffpl...

Stupid question: Could you give me an exact command line how to enable the ffplay-codec? I tried these two: In both cases, vlc still crashed and wrote this line into the log:

I've found a bug in VLC media player on Windows. Everytime I play a FFv1 video faster than the player can load / decode it, it crashes. It's reproduceable. Google found this old thread , where someone had the same probleme but didn't realize that it's a question of speed. So if you have a fast compu...

If I want a log, I do the following: Menu->Tools->Messages. Set Verbosity to 2. Hit Play and see how the log is written into the Messages window. If you wanna have it as a file, click "Save as...". It is important to mention that you only get the full log when the Messages window is alread...

Hello people, is there any way of finding out, how the quality of the received dvb-signal is? On the forums there seem to be people who got the information from the message log of vlc. So I set the verbosity level to 2 and got tons of information but nothing concerning the signal strength. Google an...

Video encoding needs lots of cpu power, this is true. But just a little example for the size of uncompressed video: resolution * size per pixel = size per frame 1280 * 1024 * 3 = 3,75 MiB So if you want to livestream uncompressed video of a typical desktop resolution at 10 fps, you need 37,5 MiByte/...

Why do you need 3 machines? This doesn't sound rational to me. The computer which captures its screen will have to encode the video anyway. I think it's not possible to strean absolutely uncompressed data with vlc (that would need a lot of bandwidth). So why not encoding the video only once (like yo...
