My working environment: Ubuntu 24.04.1

I won't be able to run vlc after successfully built and installed from source.

Hi, all: I'm trying to build VLC from source from scratch again. I pasted my configuration summary in pastebin: [url]https://pastebin.com/rYSSaZQg[/url] .

Hi, all: I actually have successfully built VLC 4.0,0, and I definitely can run it via command line in bash, but still got a lot of ERROR messages on main libvlc error: stale plugins cache . ➜ ~ vlc VLC media player 4.0.0-dev Otto Chriek (revision 4.0.0-dev-6701-g4790c810ab) [00005626d3d1db80] main ...

You might be correct. I was actually building the most recent GIT version (should be 3.0.4), but with VLC from repository installed （version 3.0.3-1) .

However, I cannot remove the installed version 3.0.3-1 from repository because there are so many other packages relying on this one...

Exactly the same problem here....
Looks like vlc is NOT compatible with current FFMPEG and a lot of other packages?

Cheers

But, do you have a plan to have VLC been compatible with lua5.3?

Hi, all: I tried to compile vlc3.0.0 with QT5 and lua5.3. Actually, after some modification, I solved all my issues during the configuration, building, and installation. I mean, I have vlc-git successfully built and installed. However, when I tried to run vlc, I got the following error messages. Can...

Have the same issue with current VLC-3.0.0-git.
I'm thinking it is the time to try lua5.3, but it seems VLC-3.0.0-git is still based on lua5.1 ???

Hi, Andrew:

You are absolutely correct. After I successfully installed gpac, I got

mp4: gpac

Hi, all:

I'm wondering what is the simplest way to stream data from an IP camera by using libVLC?
I'm trying to embed the VLC/C++ based code into my application. My target is to get images frame by frame, instead of just broadcasting..


Any suggestions?

Cheers
Pei

Pity... It seems VideoLAN is only for users to broadcast, rather than for researchers to analyze what's inside the video files.

You cannot.

Did u ever try FFMPEG? If so, you should know what every video file is mainly composed of two (or even more) streams, including: an audio stream a video stream a subtitle stream etc. I'm not splitting a video file into raw files, but splitting a video file and get the raw data ! I need to analyze th...

Hi, aipragma: I've got exactly the same problem as you mentioned here. Actually, I'm not trying to build VideoLAN. What I'm trying to build is just schroedinger-1.0.11 based on orc-0.4.16 In fact, if I typed $orcc --version I got Orc Compiler 0.4.16 and, I did all the things suggested by http://www....

Any example including both the video and audio streams? Cheers Pei For those who want the answer, it can be found in the SDL example http://wiki.videolan.org/LibVLC_SampleCode_SDL . To access pixels, the callbacks have to be used. In the callback (unlock) function (defined by vlc see SDL example), a...

Hi, all:

Any sample code for decoding an arbitrary video files into a video stream and an audio stream by using libVLC?
Looking forward to analyze both streams from my side.

Thank you very much...
