Redux WebSocket Middleware: Example

This Gist provides some code examples of how to implement WebSocket stream handling using a Redux middleware. Please be aware that this is only provided as an example and that critical things like exception handling have not been implemented.

A more complete version has been packaged, tested, and is available on GitHub as redux-websocket. This library has also been published to npm at @giantmachines/redux-websocket.

Middleware

This module represents the foundation of the middleware and implements the ideas presented above. The exported function is used during the creation of the Redux store (see the following snippet).

Converting mkv to mp4 with `ffmpeg`

Essentially just copy the existing video and audio stream as is into a new container, no funny business!

The easiest way to "convert" MKV to MP4, is to copy the existing video and audio streams and place them into a new container. This avoids any encoding task and hence no quality will be lost, it is also a fairly quick process and requires very little CPU power. The main factor is disk read/write speed.

With ffmpeg this can be achieved with -c copy. Older examples may use -vcodec copy -acodec copy which does the same thing.

These examples assume ffmpeg is in your PATH. If not just substitute with the full path to your ffmpeg binary.

Single file conversion example

Use setPopupContent() to update a popup periodically.
