The VideoLAN Forums

I'm familiar with linking a web page to images, since each image is a file and I can put a link in a web page to point to it, but how can one link a particular frame in a video to something ? The link, possibly one of many -- one for each chosen frame, would have to be stored in the video file, not ...

Clicking on a web page identifies a point in space. I want to click on a video to identify and go to a point in time.

I want to have a mp4 file be able to access other video files for additional information. Think of the mp4 as a new kind of web page. VLC becomes a video browser. Video, unlike a web page, is of infinite extent. So each video file could enable one to access additional video within its extent. And on...

Yes, each frame could contain a different URL, although it is possible that a few successive frames would contain the same URL.

I want to play a video in VLC Media Player, click on a particular video frame, or press a special function key while a particular frame is playing, and open a browser window to the media whose URL I have embedded in that frame. And so on for successive frames, each with a URL to a different media fi...

I agree with that provided there's enough information to figure out what is going on. The syntax of my command above became even more complex when I needed to "nice" it, which meant I needed some kind of quotes around the entire cvlc command, which already had embedded quotes. I could not ...

Many thanks, StCyr, for finding one of my typos. A second typo, which caused the mixup with '-treaming_video_folder', was my use of single quotes instead of double quotes around the entire duplicate string. This caused bash to not see my variable names. Here's a working command, with a few other but...

I want to simultaneously create rtsp and livehttp video streams from the same live H.264 source in cvlc. I can individually create either kind of stream just fine, and I can also create two rtsp streams simultaneously using the 'duplicate' tag, so my basic setup is right. However, something is wrong...

What command do I use in CVLC in Linux to convert a h.264/mp4 file into the HLS/ts/m3u8 format ? I just want to remux/transmux the h.264 stream in the input video file, keeping the original resolution, frame rate and quality. I do not want to transcode it since the format remains h.264 throughout. I...

Thank you for your reply. I understand from your Documentation:Streaming HowTo/Command Line Examples that there is livehttp capability. Does it do Apple HLS -- HTTP Live Streaming ??? If so, I would be tickled pink (happy) ! Is this the correct usage, where the video source (/home/vout1) and the apa...

Thank you for your reply.

Since VLC Media Player is widely admired as the Swiss Army Knife of video software, is there any chance RTSP/HTTP on the CVLC server side could be implemented soon ?

Did you try a space in front of :sout=#xxx ?

I've tried this command to get rtsp over an http tunnel, but no luck: cvlc </home/vout1 -vvv stream:///dev/stdin --sout '#rtp{sdp=rtsp://:8554/}' --demux=h264 --h264-fps=10 --rtsp-http --rtsp-http-port=8080 My source is 10 fps, so I match it with -h264-fps=<> I'm not clear on what parameters go in t...

Can you give a complete CVLC command line to show how to do this on the sending end ? I thought one would want to control which pair of adjacent ports the sender uses so one knows what pair of ports to open through a router for access to these streams from the Internet.

What happens if you use the desktop to configure VLC streaming, then you go to a command prompt and issue: sudo ps -Af | grep vlc It should tell you the full command being used by vlc. I have not tried this procedure with VLC due to a problem with my Pi's desktop, but I use ps -Af all the time to se...

I have tried adding :rtsp-tcp to the end of the CVLC command line but it does not work. Please show a complete command line. Also, how do I specify the http port used for tunneling ?

I took another stab at it, but no luck. Taking into account all of the above, and a number of posts, I now have this command line: cvlc </home/vout1 -vvv stream:///dev/stdin --sout '#rtp{sdp=rtsp://:8554/}' :demux=h264 :h264-fps=10 :rtsp-tcp As before, I can view the video when viewer and camera are...

I found an answer for my own question, but I have a new question -- how do I use http tunneling for the stream to avoid the multiple ports problem of rtsp ? First, to specify the input frame rate to stop, or at least greatly reduce, endless buffering on both ends of the connection, add this to the e...

I'm trying to encode a h.264 960x540 @ 10 fps stream into rtsp. It constantly buffers on both the transmit end and the receive end. The stream usually only stays up for less than a minute on VLC Media Player on a PC. I set caching on the PC to 15000 mS, but it does not seem to help. Both transmitter...

Could there be a problem with the video processing in vlc ? My earlier posts above assumed the problem was with pulseaudio because I've seen posts that pulseaudio can use most of the cpu. But in fact, it's vlc that's using 95+% of the cpu, and pulseaudio is not running. Here, again, is the console t...

What should I check in the local firewall or security framework ? Ubuntu firewall (ufw) is not installed. When I install everything in Wheezy, it works. But now, when I install everything in Jessie, and use the same commands as before, it does not work any more. Something changed. I do not have the ...

I see that PulseAudio is trying to use the same port, 8081, that I am trying to use, even though I told it not to run. I see several configuration files in /etc/pulse. What should I edit to tell PulseAudio to use a different port, or better yet, not to run at all ?

Thank you.

Thank you but I still get the same errors as before. I changed the command to this: cvlc --no-audio --no-sout-audio < /home/vout1 stream:///dev/stdin --sout '#standard{access=http,mux=ts,dst=:8081}' --h264-fps=5.0 :demux=h264 & It's in a script, stream_8081.sh, with the usual /bin/bash. I invoke...

How do I run cvlc so it streams video WITHOUT invoking audio on Jessie ? It ran fine on Wheezy but always gives this error with Jessie: PulseAudio output error: PulseAudio connection failure: Connection refused VLC uses 95% of my cpu, apparently waiting endlessly to open an audio connection that nev...

Thank you for your reply. It is purposely a low data rate file, with high quantization, and a nominal frame rate of 5 fps. It plays fine in HTML5 in Chrome on a Windows PC. How low is low ? Why does it work in VLC 2.1.3 but not 2.2.3 ? Can you tell me more about the issue and when it might be fixed ?
