FFmpeg cheat sheet

A list of useful commands for the FFmpeg command line tool.

Download FFmpeg: https://www.ffmpeg.org/download.html

Full documentation: https://www.ffmpeg.org/ffmpeg.html

Basic conversion

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

	// Use class fields!

	// Here's what you might be doing today...
	class A extends B {
	constructor(...args) {
	super(...args)
	this.foo = 'bar'
	this.foobar = `${this.foo}bar`
	}

	## Pre-requisite: You have to know your last commit message from your deleted branch.
	git reflog
	# Search for message in the list
	# a901eda HEAD@{18}: commit: <last commit message>

	# Now you have two options, either checkout revision or HEAD
	git checkout a901eda
	# Or
	git checkout HEAD@{18}

	#!/bin/sh

	ECHO='echo '
	for branch in $(git branch -a \| sed 's/^\s*//' \| sed 's/^remotes\///' \| grep -v 'master$'); do
	if [[ "$(git log $branch --since "6 months ago" \| wc -l)" -eq 0 ]]; then
	if [[ "$DRY_RUN" = "false" ]]; then
	ECHO=""
	fi
	local_branch_name=$(echo "$branch" \| sed 's/remotes\/origin\///')
	$ECHO git branch -d "${local_branch_name}"

	# The command finds the most recent tag that is reachable from a commit.
	# If the tag points to the commit, then only the tag is shown.
	# Otherwise, it suffixes the tag name with the number of additional commits on top of the tagged object
	# and the abbreviated object name of the most recent commit.
	git describe

	# With --abbrev set to 0, the command can be used to find the closest tagname without any suffix:
	git describe --abbrev=0
