Handbrake is one of the best free (and open-source) video converters around. It's fast, powerful, and simple. It's also quite good at converting audio.
It's a good match for you because it's...
Free (Zero Cost and FOSS)
Very lightweight - it does nothing but convert stuff
Extremely feature-filled - you can tweak every aspect of conversion
Simple and ...
ffmpeg would do this, and I've had excellent luck with the winff front end to it. It'll give you the commands should you want to do it manually, let you batch stuff out, or strip out the audio. It also has a sane set of common presets for things you want to do
I like Format Factory. It supports a very wide range of formats and media types.
Its features include:
Fast and light, it does nothing but convert software.
Supports a wide range of formats and media types.
Supports batch converting.
Is free as in beer.
I'm not sure if it supports FLAC, though...
I use youtude-dl for downloading videos from YouTube. It's a console program (without any ads), written in Python. I've used it on Windows and Linux (it worked well) and according to the official site it should work on Mac OS X too.
It also supports extracting audio. You can set the format too, for example:
youtube-dl --extract-audio --audio-format mp3 "...
You could use Audacity.
Free, open-source and multiplatform software.
Includes processing options for removing noise, and normalising volume.
Can detect silence between tracks to help with conversion.
There is a tutorial for doing precisely what you want: http://manual.audacityteam.org/o/man/tutorial_copying_tapes_lps_or_minidiscs_to_cd.html
I'm going to answer this by recommending gstreamer. You're probably going to hate this answer, because it technically satisfies your requirements, while not being GUI-based. But that's okay, because someone else may find that this is the best tool for the job for them.
Basically, if you get a build of gstreamer with all the codecs enabled, it supports an ...
From the definition of munpack:

You can use FFmpeg:
Free and open-source
Runs on Windows, Mac and Linux
Allows to split video into pictures: e.g. ffmpeg -i input.mov -r 0.25 output_%04d.png to get a picture every four seconds.
Is CLI so you can batch.
Supports most of the video formats.
Can convert from mp4 to gif. You can apply some effects or resize the video to balance between quality and file size.
You haven't posted your mp4 sample, so I am using my own.
ffmpeg -i sample.mkv -y sample.gif
Result 12M (Note: it won't be hosted foverer here):
According to this article.
What you're looking for is probably a Fast Fourier Transform, or "Frequency Analysis".
Audacity can do this, with the Analyze -> Plot Spectrum… tool.
This will output a graph, and you simply find where it peaks to ascertain the Hertz value of whatever sound you were analyzing. This of course only works if the tone is constant.
If your sound file ...
I'll presume the DVDs aren’t copy protected since they are in ISO format. My software to go considering your requirements would be HandBrake (runs on Ubuntu, Windows and Macs). Handbrake reads pretty much any format you throw at it.
Note on Ubuntu: in case your DVD image is copy protected or won't play, you need to be sure that libdvdcss2 is installed. ...
You can use TiMidity++:
free and open source
Linux and Windows (although it seems to be painful to make it work on Windows, but maybe things have improved since then)
can convert MIDI files into WAV files: timidity input.mid -Ow -o out.wav
I have used Handbrake for this.
It is open source and available for Windows, Mac and Linux.
You can set it to transcode the subtitles and / or select sound tracks if these are available on the DVD.
It isn't particularly fast but it does the job.
Except for two caveats (price and ISO see below) DVDFab will work great for that.
The only functionality caveat: There is a chance it won't natively open ISO files (i.e. I can't remember) - in which case you would have to extract it to a dvd-video folder or mount it using for example PowerISO (Free unlimited time, limited functionality but enough for this ...
I would recommend DVDx
DVDx is open source and available as a free trial on Linux, Windows, and OS X. DVDx can be used to decrypt and copy ISOs from or rip DVDs, HD-DVDs, and Blu-ray discs. DVDx supports ripping to many different formats out of the box including:
DVDx does support burnt-in subtitles.
As for size, the final ...
Freemake Video Converter does this. From the homepage:
Freemake is the only free video converter with integrated CUDA and DXVA technologies for the fastest ever video conversion and less CPU usage. The software automatically detects the optimal conversion parameters and switches on/off CUDA and DXVA for better conversion results.
I have been using this ...
VLC is a free and open source cross-platform multimedia player and framework that plays most multimedia files as well as DVDs, Audio CDs, VCDs, and various streaming protocols. Including both of the formats that you mention, (note that .m4v is actually MPEG-4). It includes the ability to convert between file formats both from the GUI and the command line.
According to Wikipedia, m4v is a video container format for x264, AAC and Dolby Digital. Knowing this, you can import your video in Avidemux and configure codecs like:
To add even more compatibility with Apple's products, you can configure the MP4v2 Muxer to add iPod metadata. When saving video, don't forget the m4v extension.
free and open-...
I can't believe that in the other question no one mentioned Avidemux.

FFmpeg is the media converter. If you don't want to use a command line to access it, use the FFE frontend if you're on Windows.
FFE uses your existing installation of FFmpeg (which must be added to your PATH) and executes the command line instructions for you. It's not as powerful for doing very advanced things, but it allows you to do almost anything a ...
Freemake offer a Youtube converter to many different formats including mp3. Whilst I have never used it, I can vouch for their products as I have used both their Video Converter & Video Downloader with great success. Its a free download with no registration required.
Platforms: Windows XP/Vista/7/8
Yes, as discussed in comments, ImageMagick will do your task quickly and a efficiently. To do what you want in windows you could use this (windows) batch file: (Just change the background colour (bg) - can be almost any color identifier - font path (f), font size (ps), extension/format (ext), size(s)). See the ImageMagick docs for more options you could do/...
