This is working for me Andrew. In your html head add this small piece of js: var video = document.getElementById(‘video’); video.addEventListener(‘click’,function(){ video.play(); },false); Or, just add an onlick attribute directly to your html element: <video src=”https://stackoverflow.com/questions/5278262/your_video” width=”250″ height=”50″ poster=”your_image” onclick=”this.play();”/>
Set the currentTime property back to 0.
I’ve found. It was so simple that I didnt even see it… /** * @param {Blob} videoFile * @param {HTMLVideoElement} videoEl * @returns {void} */ function display( videoFile, videoEl ) { // Preconditions: if( !( videoFile instanceof Blob ) ) throw new Error( ‘`videoFile` must be a Blob or File object.’ ); // The `File` … Read more

Some questions i found just pasting here that might help you. (Not tested) How to Build FFmpeg for Android Compiling … Read more
If you are on android-8 (Froyo) or above, you can use ThumbnailUtils.createVideoThumbnail: Bitmap thumb = ThumbnailUtils.createVideoThumbnail(path, MediaStore.Images.Thumbnails.MINI_KIND);
After reading the documentation of VideoCapture. I figured out that you can tell VideoCapture, which frame to process next time we call VideoCapture.read() (or VideoCapture.grab()). The problem is that when you want to read() a frame which is not ready, the VideoCapture object stuck on that frame and never proceed. So you have to force … Read more
You could attach the image (as a pixmap) to a label then add that to your layout… … QPixmap image(“blah.jpg”); QLabel *imageLabel = new QLabel(); imageLabel->setPixmap(image); mainLayout.addWidget(imageLabel); … Apologies, this is using Jambi (Qt for Java) so the syntax is different, but the theory is the same.
Canvas.drawImage must be based on html content. source here is a simplier jsfiddle //and code function capture(){ var canvas = document.getElementById(‘canvas’); var video = document.getElementById(‘video’); canvas.getContext(‘2d’).drawImage(video, 0, 0, video.videoWidth, video.videoHeight); } The advantage of this solution is that you can select the thumbnail you want based on the time of the video.
Build your AVPlayerItem in a background queue as much as possible (some operations you have to do on the main thread, but you can do setup operations and waiting for video properties to load on background queues – read the docs very carefully). This involves voodoo dances with KVO and is really not fun. The … Read more
As it was pretty much covered here, what you are trying to do here is not possible with plain, old-fashionned WebRTC (strictly peer-to-peer). Because as it was said earlier, WebRTC connections renegotiate encryption keys to encrypt data, for each session. So your broadcaster (B) will indeed need to upload its stream as many times as … Read more
