Otherwise, you should go to Video > Video Track and choose Track 2. Now, if you have the right version of VLC Media Player, it will work.

But if everything is done correctly, we will have two videos playing in sync in VLC Media Player. Doing it might be a bit tricky and the results achieved might differ in different versions of VLC Media Player. We can add a third or even a fourth video. So, an extra media file (video or audio) will load and play at the same time. Before, the same result was achieved by opening two instances of VLC and aligning them to share the screen and play them. With the modern version of the VLC, it can natively open and synchronously play two media files. Or, we might need a mashup where we use the audio from one video and the visuals from the other one. We might have to open two videos simultaneously to compare them. These settings are usually accessible in OpenCV through t().There might arise a need when we have to open two videos side by side using VLC Media Player. If you click on "Advanced Options" and then check "Device Properties," VLC will show which settings (exposure, focus, etc.) can be tweaked through DirectShow. You can also start multiple VLC instances to attempt simultaneous streams. VLC can enumerate all of the cameras available from DirectShow, which is the same API that OpenCV's VideoCapture uses by default.

You can disable multiple Windows in the preferences. Now, every media file that you open from the Windows file explorer or any other place will open in a completely new VLC Media Player window. VLC, by default, can open multiple windows when you open another video at the same time. Under Playlists and Instances, uncheck the option that says Use only one instance when started from the file manager. When debugging video capture issues on Windows, it can also be useful to open the camera streams with VLC. VLC is a popular media player for Windows.

If that works, then you may very well be looking at a bandwidth limitation.

In my experience, with 1080p color video at 30 fps and H.264 encoding, only one camera stream fit onto a single USB controller.Īn easy test to see if you are bandwidth limited would be to modify your program to explicitly close each stream after it is tested ( cap.release()), so that your test program only opens one camera at a time, like the Windows camera app. 25 Things You Can Do With QuickTime Player macmostvideo 15K views 4 months ago run multiple instances of VLC in MAC OS / open multiple video files in separate vlc window in mac os. The exact details of how many cameras you can support on one USB channel depend on the resolution, framerate, and video compression technology. Cheers.ĭo your webcams support USB3? Based on my practical experience with webcams and OpenCV, most common cameras only transmit on the USB2 standard, at 480 MBit/s. My project involves doing this to show realtime USB webcam feeds on the laptop from multiple cameras.Īny help and advice appreciated also potentially interested in (Python-based) alternative solutions. I have created the shortcut for opening the multiple panes (which is working fine). I know I can create multiple, like 3+, cv2.imshow() frames if I use the caps that work. I recently downloaded the new Windows Terminal.

And the Windows 10 camera app lets me scroll between all 3 working and connected webcam feeds.

Results: i : 0 /// result: TrueĪs with other sample code I tested, only 2 webcams can be registered and show frames in Python. That first argument, test, returns True/False depending on if the frame can be read. (Quick notes on the USB - it's a USB 3.0 hub, laptop port is USB 3, and I even have an active USB female-to-male cable going into the laptop, so given this and the Windows app working, I generally trust the hardware.)īelow I did some raw testing of cv2.VideoCapture(src) with the results below: cams_test = 10 However, my OpenCV Python code can only ever find two. Using the "camera" app on Windows, I can change the camera source one at a time and confirm that all 3 webcams are working. I'm trying to create 3 real-time capture frames with webcams into a USB hub into my laptop.
