Deleted blob from memory

[SergeyKozlov]

Hi.

Each time a new video is stored in the memory of the explorer?
How can I make the old one deleted from memory when recording a new video?

Thank you.

I had this same issue and the only way after many hours of trying things, is to refresh the browser window. Chrome has a limit of 500mb. If you record consecutive short videos - you eventually reach 500mb and things go array depending on your application. You can't write to the blob after 500mb. I inserted some code in my application that after the video is saved to a file - it refreshes the browser window thus resetting the blob size to 0 in memory.

I can confirm the same behavior @johnnylawson is describing. Even saving off the captured data in the ondatavailable event still eats up the limit.

Hello everyone.
In fact, I have long found a solution to this problem.
First I create an object.

recordingDIV.querySelector('button').onclick = function () {
    var button = this;
    if (button.innerHTML === 'Stop Recording') {
        //stopButtonRecording(button); // ==
        button.disabled = true;
        button.disableStateWaiting = true;
        setTimeout(function () {
            button.disabled = false;
            button.disableStateWaiting = false;
        }, 2 * 1000);
        button.innerHTML = 'Start Recording';
        function stopStream() {
            if (button.stream && button.stream.stop) {
                button.stream.stop();
                button.stream = null;
            }
        }
        if (button.recordRTC) {

Then I delete the object when I no longer need it.

delete button; // destroy object

In addition, you can use a native function:
