Ubuntu – Convert .mp4 to .ogg keeping only the audio, with Ubuntu 14.04 and avconv

How to convert a .mp4 file (downloaded from YouTube) to .ogg? (keeping only the audio)

When Ubuntu had ffmpeg I could just do ffmpeg -i file.mp4 -acodec vorbis file.ogg

Now we have to do without ffmpeg, but avconv seems to have a different syntax:

$ avconv -i file.mp4 -nv file.ogg
Unrecognized option 'nv'.
Error splitting the argument list: Option not found

@Nicolas Raoul you made a little mistake, it's not -nv it's -vn try:

avconv -i file.mp4 -vn file.ogg

it will work.

Ubuntu – How to do screencasting (desktop recording) with high quality audio and video

The solution I like is to use SimpleScreenRecorder. Here's how I did it:

How to build and install latest SimpleScreenRecorder from git?

My solution turned out to be simple to follow once I got the help I needed. I hope others can follow the dev's git instructions now.

Here's more info on SSR:

Main page - SimpleScreenRecorder - Maarten Baert's website

SimpleScreenRecorder is a Linux program that I've created to record programs and games. There were already a few programs that could do this, but I wasn't 100% happy with any of them, so I created my own.

My original goal was to create a program that was just really simple to use, but as I was writing it I started adding more and more features, and the result is actually a pretty powerful program. It's 'simple' in the sense that it's easier to use than ffmpeg/avconv or VLC, because it has a straightforward user interface.

Features

Graphical user interface (Qt-based).
Faster than VLC and ffmpeg/avconv.
Records the entire screen or part of it, or records OpenGL applications directly (similar to Fraps on Windows).
Synchronizes audio and video properly (a common issue with VLC and ffmpeg/avconv).
Reduces the video frame rate if your computer is too slow (rather than using up all your RAM like VLC does).
Fully multithreaded: small delays in any of the components will never block the other components, resulting is smoother video and better performance on computers with multiple processors.
Pause and resume recording at any time (either by clicking a button or by pressing a hotkey).
Shows statistics during recording (file size, bit rate, total recording time, actual frame rate, ...).
Can show a preview during recording, so you don't waste time recording something only to figure out afterwards that some setting was wrong.
Uses libav/ffmpeg libraries for encoding, so it supports many different codecs and file formats (adding more is trivial).
Can also do live streaming (experimental).
Sensible default settings: no need to change anything if you don't want to.
Tooltips for almost everything: no need to read the documentation to find out what something does.

Ubuntu – How to cut audio file with avconv

I think the original problem was with the formatting of your time stamp.

The format is HH:MM:SS

I am not sure I am understanding your question about the order of the options. I do not think it matters as long as -i is followed by the input file name and -ss HH:MM:SS followed my -t HH:MM:SS

The -ss HH:MM:SS is the starting point, and -t HH:MM:SS is the duration

so -ss 00:01:00 -t 00:05:00 would start at the one minute mark and run for 5 minutes.

On my system, using ffmpeg, order does not matter (you can specify time or input file in any order so long as -ss is followed by the duration (-t) )
