No, correct. CPU depends however mostly on the output size, and the desired quality. I start one instance of VLC per channel. I never tried more then 4 channels simultaneously. Of course VLC uses more then one thread and more then one CPU, But load is about 8% (of 8 CPUs) with one channel. A new I7 ...

on My PC (MacOS) a 1.1Mbit/s DVBS to h.264 stream needs about 70 to 100% of one core of a 2.4Ghz CPU, E5620@2.4.ghz.
How many channels to you want to stream ? 4 or 16 ?

You have to try this out yourself, it is not possible to guess a number of users because this depends on the bitrate, your network topolgy and the cpu of the machine which does the streaming.
But, your WiFi will most likely crap out first.

I am used to click an url starting with rtsp: from Safari. Now, with VLC 2.1.2 I get the Error message that the file cannot be opened. When I look into the playlist i see: "file:////rtsp://hostname/sdpname.sdp" Playback of the rtsp stream however works fine when I choose to open network an...

UDP has no handshake, and wireless lan is not a switched network, and is has a high latency compared to Ethernet. Even if a multicast reaches not other networks, it is broadcasted across all addresses in your home network. If you send a high bitrate stream with udp/multicast over a wired or wireless...

I dont have any experience with the Xbox, but know, that xbox is able to playback wmv and mp4. What happens if you use the vlc built in streaming/transcoding wizard, choose your file, then choose stream and transcode video + audio to mp4 via http, then point your xbox video player to the IP and port...

A transport stream does not care about the contents inside. Did you try to transcode your recording ? That should not be necessary until you want to preserve harddisk space.
if you just do something like: sout=#standard{mux=ts,access=file,dst=/test.ts}
you should get exactly what you received.

Try to save to a Mpeg Transport stream instead.
I dont know what exactly VLC does here, but, a transport stream should be playable regardless if recording is still in progress or finished.

install something like Darwin Streaming server on a separate machine.
Or try multicast instead of unicast, However this may lead to lost packets, and load on the whole network. Does not work reliable with WiFi

with 3 Streams 640x420p 25fps, 1.2Mbit/s AAC audio 192kbit, my real 8 CPUs are at a comfortable 50% load. I think 4 Streams should not be a problem with a modern I7 CPU. I dont know anything about the resources you need for capturing the Video. I have no experience with this card. Someone else shoul...

The CPU you need depends on the output bitrate and resolution. The larger these Values, the more CPU you will need. What Bitrate and resolution do you plan ? My home System is able to transcode and stream 2 1080p streams with 2.4Mbit/s (decoded from mkv on harddisk), I have not checked how much more...

If you dont have a big amount of files which you want to play, just launch multiple instances of VLC.

Works for me. The difference however is, I use QTSS in MacOSX - but, that should not make a difference. It does not work with VLC version 2 releases for me (when using VLC as the transcoding engine), see here: https://forum.videolan.org/viewtopic.php?f=4&t=114968 also I use h264 and, not mp4v as...

also try "--sout-avcodec-strict=-2" if you have not already done this.

Try this ? Dont know if this helps, but it will help in case VLC ends the playback. :START "C:\Program Files (x86)\VideoLAN\VLC\vlc.exe" dshow:// :dshow-vdev="Osprey-100 Video Device 1" :dshow-adev=none:live- caching=300:sout=#transcode{vcodec=theo,vb=100,scale=1,acodec=vorb,ab=1...

I assume the actual video is on a machine behind a NAT firewall/router, and, your Server i in the internet hosted somewhere ? is port 81 connectable from the outside world to your PC where vlc is running ? Do you think that streaming will start if there is a request on port 81 ? I dont know, if the ...

for vlc 2.1.0 and lower add "--sout-ffmpeg-strict=-2"
for vlc 2.1.1, add "--sout-avcodec-strict=-2"
to the parameters.

does that help ?

Works for me now with VLC 2.1.1 - great.

You could either use VLC together with its built in Streaming server to send a rtsp or http live stream to your clients, or, instead of VLC, install the Darwin Streaming Server and deliver a rtsp stream. Or, remux the stream to flv and use JWPlayer or a similar flash player to serve it. example see ...

Followup: With vlc 2.0.7 I observed, that I sometimes have audio in the stream which comes from a previous transcoding session. I guess, this relates to the built in timeshift ? So, I added "--input-timeshift-granularity=0", however, the timeshift buffer is still 1MB, if I add "--inpu...

I use VLC for MacOSX (10.6) to transcode a DVB stream to X.264 baseline + mp4 audio latm. With VLC 1.X (1.1.10) the parameter "audio-sync" works perfect. Audio is always correct. With VLC 2.0.7, the audio is always ahead of the video. I tried to add "--audio-desync=-500" but this...

Thanks,
Good to hear that this will be fixed.
