How to draw on the top of an inherited widget (VlcVideoWidget)?

阅读更多关于 How to draw on the top of an inherited widget (VlcVideoWidget)?

How can I draw something on a VLC Video Widget? I'm using VLC-Qt library to play video on a widget in my Qt application. My application requires drawing a text (or something like) on all videos. I already tried subclassing VlcWidgetVideo and reimplementing paintEvent . The method works when no video is playing. Though immadiately after starting to play, my paintings disappear. It looks like they are under VLC's video... The code: class TrackerWidgetVideo : public VlcWidgetVideo{ // Blah blah blah protected: void paintEvent(QPaintEvent *); } // ....... void TrackerWidgetVideo::paintEvent

阅读更多关于 Play video file with VLC, then quit VLC

问题 I am working on a simple Python script that is supposed to do something, then play a video file, and then do some more stuff. I am forced to do this on a Windows XP machine with Python 3.2.3 and VLC to play my video file. I am currently using this code... vlc_path = '\\path\\to\\vlc.exe' video_path = '\\path\\to\\video\\file' subprocess.call([vlc_path, video_path]) ... to open VLC and play the video. It works nicely. However, the script waits for VLC to quit before it goes on. Which is good

GStreamer stream audio and video via UDP to be able to playback on VLC

阅读更多关于 GStreamer stream audio and video via UDP to be able to playback on VLC

I am trying to stream audio and video via Gstreamer via UDP but playback on VLC only returns video without audio. Currently I am using a sample of Big Buck Bunny and have confirmed that it does have audio. I am planning to use Snowmix to feed media to Gstreamer output in the future. Streaming from file source via UDP to playback on VLC I currently perform by: gst-launch-1.0 -v uridecodebin uri=file:///home/me/files/Snowmix-0.5.1/test/big_buck_bunny_720p_H264_AAC_25fps_3400K.MP4 ! queue ! videoconvert ! x264enc ! mpegtsmux ! queue ! udpsink host=230.0.0.1 port=4012 sync=true which allows me to

I am trying to stream video from a IP Cam to my my Wordpress site. I would like my stream to be available via common devices Windows, Mac, Android and IOS. Currently I am using VLC to stream,but I can only get a flash stream to work but I would like to do FLV, MP4 and webm. What player should I use to display the MP4 and webm video on the site? Also I don't think the calls to VLC are correct cause I can't open the MP4 and webm stream in VLC on another computer, but I can open the flv stream. VLC Script: cd "C:\Program Files (x86)\VideoLAN\VLC" vlc -vvv -I dummy http://IP/cgi/mjpg/mjpg.cgi
