    Фон бэкграунда для публиукемого потока.

    Добрый день. Уточните, пожалуйста, что имеется в виду? Если речь о потоках, добавляемых в микшер, то, если в микшер добавляется поток без видео составляющей, микшер не обрабатывает видео для такого потока. Есть только возможность отрисовать для него прямоугольник (опционально, с выводом имени...

    how to achieve CanvasStreaming to 1080p

    Probably, no. Headless Chrome does not use GPU, so transcoding will require a lot of client CPU. Also, canvas streaming requires a browser tab where canvas is rendering to be an active tab. So headless Chrome seems not a good solution for the case.

    VideoProcessor - VideoProcessor Encoding fails to keep up with decoding and decoder coded video frames queue

    Это основной симптом возникающей проблемы. Распределение нагрузки по гипертрединговым ядрам для этих процессоров работает не совсем корректно, большинство кодирований складываются на несколько ядер. В результате ядра перегружаются, и не успевают кодировать картинки, лежащие в очередях, что и...

    how to input multiple audio source on canvas streaming?

    Good day. WCS supports only one video track and one audio track in a stream. So you should use stream mixer at server side to mix all the needed tracks. Please also clarify your case: are the streams you want to mix published from different sources?

    how to achieve CanvasStreaming to 1080p

    Transcoding means server-side transcoding and rescaling For example initial canvas size is 320x240 will be decoded on the server then upscaled to 1920x1080 then encoded to H.264 stream. 1. You will get blurry 1920x1080 image because upscale will affect image quality. 2. You will utilize 1-2...

    how to achieve CanvasStreaming to 1080p

So, to publish 1080p from canvas you need to place canvas element of 1920x1080 pixels to the web page. Another option is to transcode the stream picture...

    docker image multi_arch x86/arm64

    Good day. There is no WCS builds for ARM architecture. WCS uses a lot of native code to transcode audio and video, so it is bound to x86_64. In its turn, Docker is not a full-fleged virtual machine, so it cannot virtualize hardware, just uses the platform on which it is running. The final answer...
