If you want to remove an unwanted audio track from a dual audio avi movie file, you can use the following command with Mencoder:
mencoder original_dual_audio_file.avi -o target_file.avi -oac copy -ovc copy -aid 2
or with Ffmpeg:
ffmpeg -i original_dual_audio_file.avi -vcodec copy -map 0:0 -acodec copy -map 0:2 target_file.avi
These will create a file named target_file.avi retaining only the second audio track (aid 2).
This one line command will search for all avi video files in a volume (dvd) with find, analyzes the specs with ffprobe, and filters the output through grep
find /media/cdrom/ -name '*.avi' -exec ffprobe {} \; 2>&1 | grep -F -f patternfile
Notes:
2>&1 is necessary because the ffprobe output is in stderr, not stdout
patternfile contains all the patterns to be matched by grep, one in each line.
Sites like opensubtitles.org have the annoying habit of tagging their files with subtitles like “Tip for download: Open Subtitles MKV Player” and “Downloaded from http://www.opensubtitles.org”.
Here is a fast single command to get rid of all that on all subrip (.srt) files, using find, sed, and a bit of regex:
find . -name \*.srt -execdir sed -i '/pen.*ubtitles/d' {} +
I did it for dozens of files in one command ;)
“find” searches all subdirectories below the current one (.) for every file with the srt extension (-name \*.srt) and executes the sed command that deletes on those files ({} +) the lines matching the regex pattern (pen.*ubtitles).
Taken from the handbrake.fr forum:
This information is up-to-date for HandBrake 0.9.5. It may no longer apply to future versions.
HandBrake 0.9.5 does not natively support x264 presets and tunes. However, nothing prevents you from re-creating them manually.
You can specify most x264 options (nearly all options parseable by libx264’s x264_param_parse function) via HandBrake’s advanced panel:
* –option value becomes option=value
* Options are separated by a colon.
* Options that do not require a parameter can be specified as either option or option=1
The MacGUI’s advanced panel will automatically add =1 if you don’t specify a value.
* In most cases, no-<something>=1 and <something>=0 are equivalent.
This isn’t true for deblock – to disable it, you must use no-deblock=1; deblock=0 is the same as deblock=0,0 (the default)
A list of all available x264 options can be found on MeWiki.
Formatted for HandBrake’s advanced panel (getting rid of redundant options; e.g. –bframes 0 implies –b-adapt 0), we get:
ref=1:bframes=0:cabac=0:8x8dct=0:weightp=0:me=dia:subq=0:rc-lookahead=0:analyse=none:trellis=0:aq-mode=0:no-deblock=1:scenecut=0:mbtree=0
ref=1:mixed-refs=0:weightp=1:subq=1:rc-lookahead=0:analyse=i8x8,i4x4:trellis=0:mbtree=0
ref=1:mixed-refs=0:weightp=1:subq=2:rc-lookahead=10:trellis=0
ref=2:mixed-refs=0:weightp=1:subq=4:rc-lookahead=20
ref=2:weightp=1:subq=6:rc-lookahead=30
ref=5:b-adapt=2:direct=auto:me=umh:subq=8:rc-lookahead=50
ref=8:b-adapt=2:direct=auto:me=umh:subq=9:rc-lookahead=60:analyse=all:trellis=2
ref=16:bframes=8:b-adapt=2:direct=auto:me=umh:merange=24:subq=10:rc-lookahead=60:analyse=all:trellis=2
ref=16:bframes=16:b-adapt=2:direct=auto:me=tesa:merange=24:subq=10:rc-lookahead=60:analyse=all:trellis=2:no-fast-pskip=1
–slow-firstpass can be set by disabling “Turbo First Pass” in the Video panel.
The official x264 presets are meant to be good speed / compression efficiency tradeoffs. The options that are most useful to compression efficiency are enabled first; the less useful options are enabled in the slowest presets (i.e. once all the most useful options are already enabled).
If you’re using settings slower than the placebo preset, you’re doing it wrong (the difference won’t be noticeable).
Note: if you’re starting with an official HandBrake preset for your device, be sure to add these settings before the preset’s options (so that the HandBrake options override the x264 preset – the other way around will likely break compatibility with your device).
Some settings should be safe to override with the x264 preset values (no guarantee, however):
* b-adapt (Adaptive B-Frames)
* direct (Adaptive Direct Mode)
* me (Motion Estimation Method)
* subme/subq (Subpixel ME & Mode Decision)
* merange (Motion Estimation Range)
* aq-strength (Adaptive Quantization)
* psy-rd (Psychovisual Rate Distorsion, Psychovisual Trellis)
* partitions/analyse (Partition Types)
* trellis (Trellis)
* deblock (Deblocking)*
* rc-lookahead
* no-fast-pskip
* Some very weak devices may require that deblocking be disabled
The following settings are NOT safe to override:
* ref (Reference Frames)
* bframes (Maximum B-Frames)
* cabac (CABAC Entropy Coding)
* 8x8dct (8×8 Transform)
* weightp (Weighted P-Frames)
* b-pyramid (Pyramidal B-Frames)
* weightb
* mixed-refs
* vbv-bufsize and vbv-maxrate
(meaning that you should not enable them if they are disabled in the HandBrake preset, or increase the value)
The official x264 tunes for r1834 are:
–tune Tune the settings for a particular type of source or situation
Overridden by user settings.
Multiple tunings are separated by commas.
Only one psy tuning can be used at a time.
In HandBrake’s advanced panel:
* film: optimizes settings for film sources
Set Deblocking to -1,-1
Set Psychovisual Trellis to 0.15 (leaving Psychovisual Rate Distorsion untouched)
Set Deblocking to 1,1
Set Psychovisual rate Distorsion to 0.4 (leaving Psychovisual Trellis untouched)
Set Adaptive Quantization to 0.6
Optional: if B-Frames are enabled, add 2 B-Frames to Maximum B-Frames*
Optional: if using more than one Reference Frame(s), double the number of Reference Frames*
* While these changes are part of the tune, they’re likely to break device compatibility
Leave B-Frames and Reference Frames untouched unless you know what you’re doing
Set Deblocking to -2,-2
Set Psychovisual Trellis to 0.25 (leaving Psychovisual Rate Distorsion untouched)
Enable No DCT Decimation
Add the following options to the option string:
deadzone-inter=6:deadzone-intra=6:ipratio=1.1:pbratio=1.1:qcomp=0.8
Set Deblocking to -3,-3
Set Adaptive Quantization to 1.2
Set Psychovisual Rate Distorsion to 2.0 and Psychovisual Trellis to 0.7
Add the following options to the option string:
aq-mode=0:psy=0
Add the following options to the option string:
aq-mode=2:psy=0
Disable CABAC Entropy Coding
Disable Weighted P-Frames
Add the following options to the option string:
weightb=0:no-deblock=1
Set Maximum B-Frames to 0
Add the following options to the option string:
mbtree=0:rc-lookahead=0:sync-lookahead=0:sliced-threads=1
CFR (Constant Framerate) is set automatically by HandBrake when required
Using –force-cfr will likely cause audio/video sync issues
I have some videos I wish to concatenate into a single one, without re-encoding.
It’s very easy with mencoder.
If they are avi:
mencoder -forceidx -ovc copy -oac copy part1.avi part2.avi part3.avi -o total.avi
-forceidx forces to rebuild the index, for seeking.
But if they are MPG files i should use the MPEG container (mencoder uses avi as default, regardless of file extension)
mencoder -forceidx -of mpeg -noskip -mc 0 -ovc copy -oac copy part1.mpg part2.mpg part3.mpg -o total.mpg
The mencoder manual advises the use of -noskip -mc 0 when muxing mpeg files.
For MPEG1 format this has to be specified, because MPEG2 is the default:
mencoder -forceidx -of mpeg -noskip -mc 0 -mpegopts format=mpeg1 -ovc copy -oac copy part1.mpg part2.mpg part3.mpg -o -o total.mpg

Update: I found split2flac,which does all this automatically.
From aidanjm’s stuff :
Lossless audio files can be split by cue file using “shnsplit” (part of the “shntool” package). You will also need the “cuebreakpoints” tool (part of the “cuetools” package) and “cuetag” to transfer the tags.
Avimerge comes from the Transcode project.
avimerge -i original.avi -p newaudio.mp3 -o new.avi
There are common hardware (stand-alone) player limitations for Xvid video:
