Use mplayer engine to show live video
Mark81 last edited by
I need to show a video stream (h264 1080p30 noaudio mpegts/udp) in a QML Page. I tried QtAV (based upon ffmpeg) and it works but has a HUGE latency - about 1 second!
Using mplayer from command line (
mplayer -nosound -framedrop -benchmark udp://127.0.0.1:1235) I achieve a very low latency that is suitable for my application.
The final goal is:
- show the live video stream on a fullscreen QML Page
- draw some elements on the top of the video (like an overlay)
- record the whole stuff (video + overlay) to a video file
do you have any advice on how to achieve that?
I don't have to use mplayer at all costs, but I really need a low latency (< 100 ms) for display the video. Of course the recording might be delayed.
