vlc

问题 This is probably a simple question but I'm currently working with vlcj to make a video player for a project. I have a basic player working but only when I have the VM arguement -Djna.library.path="C:\Program Files\VideoLAN\VLC" defined in the debug configurations window. My question is if I need to create a version of this project to run outside of Eclipse do I need to define this argument in my code or will my program run in this way without problems indefinitely? Thanks to anyone who

问题 I am trying to save audio clips (15 seconds per clip) from live stream using VLC library. I am unable to find any option that could allow me to record only 15 seconds from the live stream. Thus I ended up using timer in my code, but the recording clips sometimes contain 10 seconds, sometimes 20 seconds (rarely 15 seconds). Also, sometimes the audio content is repeated in the clips. Here is the code (I am a newbie so please guide me) Code.py import os import sys import vlc import time

问题 I want to know if it is possible to retrieve the now playing info (name of file, time elapsed, etc.) for VLC from the command line. I want to then use Java to use this info somewhere. One possibility might be to use JNA, but not sure how that would work. I searched everywhere but it only tells me how to start a file from command line. 回答1: Apparently VLC comes with a small Http server which can be used to send commands to the player. You launch the server by issuing % vlc -I http (--http-src

问题 I have decrypted one video into the memory and wanted to play it into vlc from there only. By searching on internet I founded libvlc_media_new_callbacks(instance, open_cb, read_cb, close_cb, opaque) API which is used to play the video from the memory. I am not getting any detail about how to use this and how can i specify it's perimeter, Is there anyone who can explain it's implementation to me. 来源： https://stackoverflow.com/questions/65885578/how-to-use-libvlc-media-new-callbacks-to-play
