Use ffmpeg to stream video from a dahua 4300s to a file or files

You can use ffmpeg to directly pull frames off of a dahua 4300s at full resolution. May be a good alternative to pricey dvrs which likely cannot record at full resolution, may not work with the camera, or are prohibitevly expensive

Simple Stream to file

Simple stream to file. Full resolution

ffmpeg -loglevel debug -rtsp_transport tcp -i "rtsp://admin:[email protected]:554/live" \

-c copy -map 0 foo.mp4

Grab ffmpeg from https://www.ffmpeg.org/download.html

It's a command line tool which means you will have to type things with your keyboard instead of clicking on buttons.

The most trivial operation would be converting gifs:

ffmpeg -i your_gif.gif -c:v libvpx -crf 12 -b:v 500K output.webm

-crf values can go from 4 to 63. Lower values mean better quality.
-b:v is the maximum allowed bitrate. Higher means better quality.

Ember.Console

This is a set of helpers for finding the application's currently active models/routes/controllers/etc. This isn't a straightforward process because of how Ember (rightly) encapsulates application objects, but it's useful in debugging environments to be able to quickly access them. And with the beta release of Ember Data, the store is not easily accessible without helpers either.

Usage

All helpers can be called directly if you provide them an application instance:

	tell application "Finder"
	tell front window to update every item
	try
	delete (make new file at (front window) with properties {name:".refresh.tmp"})
	end try
	end tell

	# Python module for interacting with rtorrent's XML-RPC interface
	# directly over SCGI, instead of through an HTTP server intermediary.
	# Inspired by Glenn Washburn's xmlrpc2scgi.py [1], but subclasses the
	# built-in xmlrpclib classes so that it is compatible with features
	# such as MultiCall objects.
