Infos about howto play, edit and stream audio and video

Use soma

Just use curl. The resulting file is playable with common players like mplayer, xine or vlc

Download from slackbuilds and build it as root using su -, not only su. Otherwise the build will fail becaus it can't find texi2html.

This cuts out 61 seconds of all.mp3, starting at 41 min 8 sec from the beginning and writes the section to the file part.mp3. Note that no mp3 encoder is necessary and there is no quality loss.

ffmpeg -ss 41:08 -i all.mp3 -codec copy -t 61 part.mp3 

This technique works for video as well.

ffmpeg -f concat -i mylist.txt -c copy output

See https://trac.ffmpeg.org/wiki/Concatenate for format of mylist.txt

work in progress

1. mencoder uses ffmpeg
2. ffmpeg provides and uses libavcodec
3. ffmpeg seems to come from mplayer. The ffmpeg slack package points to http://ffmpeg.mplayerhq.hu
4. libavcodec does not contain x264, it is a standalone lib
5. mencoder (as well as handbrake) recommends to use x264 as video encoder
6. mencoder (as well as ffmpeg) probably need to be recompiled after x264 is installed. mencoder -ovc help should list x264 after recompile
7. mencoder provides extensive doc about howto rip a DVD. Nothing similar found for ffmpeg yet.
8. A search for ffmpeg vs mencoder on the web shows that most people recommend mencoder, because it can do more

The easiest way by far to get copies of your DVD movies is command line app HandBrake.

The Ubuntu CLI binary (Precise) works on Slack (14.0). Just download the deb package, unpack it with ar -x, untar all appearing archives and move HandBrakeCLI to /usr/local/bin.

As of Slack 14.1 the Ubuntu version handbrake - 0.10.2ppa1~vivid1 needs libass, lame and x264 from www.slackbuilds.org. And the Symlink libx264.so.142 → libx264.so.146 in /usr/lib(64).

Alternatively, as of Slack 13.0 Handbrake is available at www.slackbuilds.org. But it has many more dependencies.

It has almost no dependencies¹⁾, everything is build in. Both a binary version for Linux and the source code is available.

1. Install libdvdcss²⁾
2. Download the binary and copy it to /usr/local/bin.

Note: As of version 0.9.4 no generic tarball is available any more. But is possible to compile the HandbrakeCLI source (tested on Slack 13.0). Note that in order to compile Handbrake you need yasm which is available on www.slackbuilds.org. Note also that the build process aborts with an error, but the CLI interface works. — 2009-12-30

Note: The current binary version (0.9.3) is marked as Ubuntu Package. But it is still simply a tarball which works on Slack (tested on 13.0) — 2009-10-14

A possible alternative HandBrake is Thoggen, but it has loads of dependencies and is by far more complicated to install.

Get Info about DVD:

HandBrakeCLI -i /dev/dvd -t 0 2>err.txt

and look for the longest title.

Rip Example:

HandBrakeCLI -i /dev/dvd -o movie.mp4 --preset=Normal --loose-anamorphic -L [-a 1[,2]] [-A Deutsch[,English]] [-s 1] [-c 3]

Possibly helpful scripts for:

• Getting info about a dvd, save it into dvdinfo.txt and display it in your pager
• Ripping a DVD wit reasonable default settings
