hadnbrake has already a good command line support
just use it.. nothing fancy, but quite usefull
Code:
[andres@lucillex ~][andres@lucillex ~]$ HandBrakeCLI --help
Syntax: HandBrakeCLI [options] -i <device> -o <file>
### General Handbrake Options------------------------------------------------
-h, --help Print help
-u, --update Check for updates and exit
-v, --verbose <#> Be verbose (optional argument: logging level)
-C, --cpu Set CPU count (default: autodetected)
-Z. --preset <string> Use a built-in preset. Capitalization matters, and if the preset name has spaces, surround it with double quotation marks
-z, --preset-list See a list of available built-in presets
--dvdnav Use dvdnav (Experimental)
### Source Options-----------------------------------------------------------
-i, --input <string> Set input device
-t, --title <number> Select a title to encode (0 to scan only, default: 1)
-L, --longest Select the longest title
-c, --chapters <string> Select chapters (e.g. "1-3" for chapters 1 to 3, or "3" for chapter 3 only, default: all chapters)
--angle <number> Select the DVD angle
--previews <#:B> Select how many preview images are generated (max 30), and whether or not they're stored to disk (0 or 1). (default: 10:0)
--start-at-preview <#> Start encoding at a given preview.
--stop-at <unit:#> Stop encoding at a given frame, duration (in seconds), or pts (on a 90kHz clock)
### Destination Options------------------------------------------------------
-o, --output <string> Set output file name
-f, --format <string> Set output format (mp4/mkv, default: autodetected from file name)
-m, --markers Add chapter markers (mp4 and mkv output formats only)
-4, --large-file Use 64-bit mp4 files that can hold more than 4 GB. Note: Breaks iPod, PS3 compatibility.
-O, --optimize Optimize mp4 files for HTTP streaming
-I, --ipod-atom Mark mp4 files so 5.5G iPods will accept them
### Video Options------------------------------------------------------------
-e, --encoder <string> Set video library encoder (ffmpeg,x264,theora) (default: ffmpeg)
-x, --x264opts <string> Specify advanced x264 options in the same style as mencoder:
option1=value1:option2=value2
-q, --quality <float> Set video quality (0.0..1.0)
-Q, --cqp Use with -q for CQP instead of CRF
-S, --size <MB> Set target size
-b, --vb <kb/s> Set video bitrate (default: 1000)
-2, --two-pass Use two-pass mode
-T, --turbo When using 2-pass use the turbo options on the first pass to improve speed
(only works with x264, affects PSNR by about 0.05dB, and increases first pass speed two to four times)
-r, --rate Set video framerate (5/10/12/15/23.976/24/25/29.97)
Be aware that not specifying a framerate lets HandBrake preserve a source's time stamps,
potentially creating variable framerate video
--vfr, --cfr, --pfr Select variable, constant or peak-limited frame rate control. VFR preserves the source timing. CFR makes the output constant rate at the rate given by the -r flag (or the source's
average rate if no -r is given). PFR doesn't allow the rate to go over the rate specified with the -r flag but won't change the source timing if it's below that rate. If none of these flags are given, the default is --cfr when -r is given and -vfr otherwise
### Audio Options-----------------------------------------------------------
-a, --audio <string> Select audio track(s), separated by commas More than one output track can be used for one
input. ("none" for no audio, "1,2,3" for multiple tracks, default: first one)
-E, --aencoder <string> Audio encoder(s) (faac/lame/vorbis/ac3/dts) ac3 and dts meaning passthrough Separated by commas for more than one audio track. (default: guessed)
-B, --ab <kb/s> Set audio bitrate(s) (default: 160) Separated by commas for more than one audio track.
-6, --mixdown <string> Format(s) for surround sound downmixing
Separated by commas for more than one audio track. (mono/stereo/dpl1/dpl2/6ch, default: dpl2)
-R, --arate Set audio samplerate(s) (22.05/24/32/44.1/48 kHz) Separated by commas for more than one audio track.
-D, --drc <float> Apply extra dynamic range compression to the audio, making soft sounds louder. Range is 1.0 to 4.0 (too loud), with 1.5 - 2.5 being a useful range. Separated by commas for more than one audio track.
-A, --aname <string> Audio track name(s), Separated by commas for more than one audio track.
### Picture Settings---------------------------------------------------------
-w, --width <number> Set picture width
-l, --height <number> Set picture height
--crop <T:B:L:R> Set cropping values (default: autocrop)
-Y, --maxHeight <#> Set maximum height
-X, --maxWidth <#> Set maximum width
--strict-anamorphic Store pixel aspect ratio in video stream
--loose-anamorphic Store pixel aspect ratio with specified width
--custom-anamorphic Store pixel aspect ratio in video stream and directly control all parameters.
--display-width Set the width to scale the actual pixels to
<number> at playback, for custom anamorphic.
--keep-display-aspect Preserve the source's display aspect ratio when using custom anamorphic
--pixel-aspect Set a custom pixel aspect for custom anamorphic <PARX:PARY>
(--display-width and --pixel-aspect are mutually exclusive and the former will override the latter)
--itu-par Use wider, ITU pixel aspect values for loose and custom anamorphic, useful with underscanned sources
--modulus Set the number you want the scaled pixel dimensions
<number> to divide cleanly by, for loose and custom anamorphic modes (default: 16)
-M --color-matrix Set the color space signaled by the output
<601 or 709> (Bt.601 is mostly for SD content, Bt.709 for HD,
default: set by resolution)
### Filters---------------------------------------------------------
-d, --deinterlace Deinterlace video with yadif/mcdeint filter
<YM:FD:MM:QP> (default 0:-1:-1:1)
or
<fast/slow/slower>
-5, --decomb Selectively deinterlaces when it detects combing
<MO:ME:MT:ST:BT:BX:BY> (default: 1:2:6:9:80:16:16)
-9, --detelecine Detelecine (ivtc) video with pullup filter
Note: this filter drops duplicate frames to
restore the pre-telecine framerate, unless you
specify a constant framerate (--rate 29.97)
<L:R:T:B:SB:MP> (default 1:1:4:4:0:0)

### Subtitle Options------------------------------------------------------------
-s, --subtitle <string> Select subtitle track(s), separated by commas
More than one output track can be used for one
input.
("1,2,3" for multiple tracks.
A special track name "scan" adds an extra 1st pass.
This extra pass scans subtitles matching the
language of the first audio or the language
selected by --native-language.
The one that's only used 10 percent of the time
or less is selected. This should locate subtitles
for short foreign language segments. Best used in
conjunction with --subtitle-forced.
-F, --subtitle-forced Only display subtitles from the selected stream if
<string> the subtitle has the forced flag set. May be used in
conjunction with "scan" track to auto-select
a stream if it contains forced subtitles.
Separated by commas for more than one audio track.
("1,2,3" for multiple tracks.
If "string" is omitted, the first trac is forced.
--subtitle-burn "Burn" the selected subtitle into the video track
<number> If "number" is omitted, the first trac is burned.
--subtitle-default Flag the selected subtitle as the default subtitle
<number> to be displayed upon playback. Setting no default
means no subtitle will be automatically displayed
If "number" is omitted, the first trac is default.
-N, --native-language Specifiy the your language preference. When the first
<string> audio track does not match your native language then
select the first subtitle that does. When used in
conjunction with --native-dub the audio track is
changed in preference to subtitles. Provide the
language's iso639-2 code (fre, eng, spa, dut, et cetera)
--native-dub Used in conjunction with --native-language
requests that if no audio tracks are selected the
default selected audio track will be the first one
that matches the --native-language. If there are no
matching audio tracks then the first matching
subtitle track is used instead.
--srt-file <string> SubRip SRT filename(s), separated by commas.
--srt-codeset Character codeset(s) that the SRT file(s) are
<string> encoded in, separted by commas.
Use 'iconv -l' for a list of valid
codesets. If not specified latin1 is assumed
--srt-offset Offset in milli-seconds to apply to the SRT file(s)
<string> separted by commas. If not specified zero is assumed.
Offsets may be negative.
--srt-lang <string> Language as an iso639-2 code fra, eng, spa et cetera)
for the SRT file(s) separated by commas. If not specified
then 'und' is used.
--srt-default Flag the selected srt as the default subtitle
<number> to be displayed upon playback. Setting no default
means no subtitle will be automatically displayed
If "number" is omitted, the first srt is default.
"number" is an 1 based index into the srt-file list
