How to splice sections of a video with avconv?
I have figured out so far that you can cut a section from a video with avconv with a command like this (cuts from 1:00-3:00):
avconv -ss 00:01:00 -i "input.avi" -t 00:02:00 -c:v libx264 -crf 23 "output.mp4"
But how would I cut two (or more) sections from the video and combine them into one video? For example, taking 1:00-3:00 as above, plus 8:00-10:00, making a final 4 minute video.
I guess I can do them separately then concatenate them, but is there a simpler way?

@Benoir nope, sorry. But as per Janus' comment you may be able to first convert both videos to MPEG (at 100% quality), concatenate them, then re-encode in your desired format. I never bothered though...

I believe you will have to cut separate chunks, then concatenate them. Don't use cat for that, as timecodes will be all over the place.
If the video chunks are mp4, use mp4box (from the gpac package) for concatenation:
mp4box -cat vid1.mp4 -cat vid2.mp4 ... -cat vidN.mp4 -new vid1-N.mp4

For combining videos use:
cat video1 video2 > video3
Click here for more info.
If you would like to use the combined video in website, you could try a new technology, called popcorn.js. You should see this video to understand how to combine multiple videos without any software and to start any video from wanted seconds. It's very interesting.
For the whole process of cutting and combining videos maybe you need a script like this:
#! /bin/bash
folder="/home/user/path-to-folder"
input="input.avi"
out1="1.mp4"
out2="2.mp4"
combine="3.mp4"
cd $folder
avconv -ss 00:01:00 -t 00:02:00 -i $input -c:v libx264 -crf 23 $out1
avconv -ss 00:08:00 -t 00:10:00 -i $input -c:v libx264 -crf 23 $out2
# add as many lines as you like
cat $out1 $out2 > $combine
You only have to change the names of variables at the start of the script.
Also You could try MENCODER for joining videos:
mencoder -oac copy -ovc copy -idx -o output.avi video1.avi video2.avi video3.avi
