Audio/Video/Image/Text/ISO Convert

Right-click on a file, and this script will decide what conversions are appropriate, ask some questions about what you want, and execute the proper command and options to convert it into something else.

Multimedia: change formats, bitrate, framerate, size, aspect ratio, and more. Also strip audio.
Audio: change formats, bitrate, volume, and more.
Multimedia and Audio: your most-used sets of options can be stored for future use.
Images: change formats, size, jpg compression, rotate, equalize, and more.
Documents: change formats, text-to-speech, text-to-jpg, and more.
Convert multi-image files, like pdf or animated gif, into a series of frames,
pdf to gif creates animaged gif, animated gif to pdf creates multi-page pdf.
Convert various "CD Images" into standard .iso files.

Comments welcome, suggestions invited, votes appreciated.

There's a lot of description here, but you don't need any of it to make this work.
Just download and extract. Then do one or more of these with the file "avconvert":
(1) move (or copy or link) it to ~/.gnome2/nautilus-scripts
(2) move (or copy or link) it to somewhere in $PATH (eg /usr/local/bin)
..(obviously don't move it twice :-)
(3) do #2, then add it as a nautilus-action (set "paramater" to "%M", check "multiple files")
(4) add it to Gnome panel/launch-bar (drag/drop or right-click panel Add/Custom-Application)

...Depending on 1, 2, 3, and 4 above (you can do any combination of these), you can now:
(1) right-click on selected icon(s) and choose the script
(2) from command line: avconvert filename (quote name(s) with spaces, multiple files OK)
(3) right-click on selected icon(s) and choose "Avconvert"
(4) click the icon to launch -or- drag-and-drop file(s) on the icon

To repeat, you can do as many of these as you want. For example: move the file to ~/.gnome2/natuilus-scripts, then link that to /usr/local/bin, then add it as a nautilus-action, then add it to the gnome-panel.

Much more than a quick shortcut to a common command, this shell script is nearly 2000 lines of code!

After all, I took the time to write this and give it away! :-) :-)

The first run will create some files in ~/.config/avconvert. The files "avconvert", "avconvert.lang", and "avconvert.ffopts.custom" may be hand-edited. A default file will be recreated if any file is missing.

When using Key-In-Options during audio or video conversion, your ffmpeg options can be saved into the menu for future use. When your Key-In options end in a comment (as in "# my conversion"), a line will be automatically added to the 'custom' section of the ffmpeg options menu.

There's a progress indicator during conversions. In most cases, it estimates that the result file will grow to the size of the source file. This is not always the case, so it may appear stuck near 0% or quickly rise to 98% depending on your conversion. Be patient - behind the scenes, the progress window stays up as long as the result file is growing.

AUDIO: Converts between various formats (see below).

VIDEO: Converts between various formats. Can also produce audio-only from a video source. Video size can be scaled by specifying a new width - the new height is calculated based on aspect ratio. A video can also be letterboxed by choosing the aspect ratio of your display device - calculation automatically determines whether to pad on top/bottom or left/right. Videos can also be rotated to compensate for the type of recorder used (this feature is the only one that relies on mencoder). NOTE REGARDING ROTATION - mencoder has some codec limitations, and depending on the source or destination file type, rotation may fail. This will be detected, but without automatically fixing it. The best course of action is to convert the source first, perhaps to AVI, then use THAT file as the source for your rotation and other changes.

AUDIO AND VIDEO: Can adjust audio volume, sample rate, bitrate. In fact, you can do anything ffmpeg is capable of. Options in default menus offer common operations, but a special KEY-IN function lets you test your own and store them in your own custom file. Further, there's a file of user-submitted options (downloaded separately).

VIDEO FRAMES: Converts an input video into a series of frames in either jpg or png format. The capture rate can range from 1 to 60 seconds between frames, or 'all'.

IMAGES: Convert between various formats. Optionally set resolution for output. If outputting jpg, optionally set quality. A single conversion can specify multiple output types and multiple resolutions.

ISO IMAGES: Why should "images" be limited to "pictures"? Generate an ISO file from source files in the following formats: b5i, bin/cue, csi, daa, mdf, nrg, pdi, uif.

IMAGE SPECIAL CASES: Converting an animated gif to a format other than gif will produce a separate file for each frame in the source. Converting a pdf to an format other than pdf does the same thing. In both cases the "progress indicator" will suggest that there was an error, but this is only because the files created are not named in accordance with what it expects. Be patient if the source contains many frames, and do not click Cancel to the progress window. Also, conversion of a .psd (or similar) which contains layers will generate multiple images in some formats (eg jpg), or an animation (eg gif), so you may want to flatten them first.

TEXT to TEXT: Various conversions between TXT, RTF, HTML, M$Office and OpenOffice, with more being added.

TEXT to SOUND: Produces an audio file from a .txt file. Choose language, gender, pitch and speed.

TEXT to IMAGE: Produces an image of your .txt file. Choose the output image size, font size, colors, border, and font. Text is automatically rewrapped as needed, based on the requested image width and font size. After wrapping, if the text will not fit on a single image vertically, multiple image pages will be generated.

GENERAL:
- The source file is not overwritten. The destination file is named for the source with a new extension.
- An image conversion will also insert resolution into the destination name.
- If any conversion would produce the source filename (eg changing image jpg quality only, or audio bitrate only, or same conversion twice), "new" is inserted into destination name or user is prompted to supply a name.

The source file is identified using the system's "file" command as well as some hard-coded extensions. If this fails, the user is asked if the source is image, audio or video.

Upon startup, "ffmpeg" and "file" are both executed against the source file, and the information gathered is displayed in the initial windows. This is helpful in deciding what choices to make, especially if the source file happens to be of an 'unknown' type.

The destination is chosen from a list of common and appropriate file extensions, or the user can choose OTHER and key in any valid file extension for the media type.

For a typical system (eg, mine :-) conversions for the following image, audio and video formats...

[ READ ME!! ] After processing, the last part of the output from the actual conversion program used is displayed to confirm proper operation or to help diagnose any problems. If there are problems, you can view the complete output: in /tmp, list the files with "ls -lrt" which will show the newest at the bottom. The files that capture conversion output are named as follows: conversion-program.NNNNN where NNNNN is the PID of the process that ran. For example, you might see "ffmpeg.8512" or "antiword.405". Just view the file and look for the first error listed, which is probably the culprit.

=====

0.56 It is now possible to replace originals during a conversion IF:
1 - converting images
2 - converting into the source folder
3 - converting to only one file type
4 - converting to only one resolution
If these conditions are all true, you will be prompted before the conversion begins. If you choose YES:
1 - originals are replaced with the converted files
2 - the new files will have a different extension if appropriate
3 - the new file names will not have the resolution inserted

0.60 You are invited to submit your own custom option sets, which will be added to a "user submissions" config file that will be posted here and available for download!

0.61 Now recognizes .vob files - just mount your DVD and rip away!

0.65 When a keyed-in option is used in audio or video conversion, if you add a "comment" (a # followed by text), then that option set will be automatically added to your ~/.config/avconvert/avconvert.ffopts.custom file for future use

0.72 There are three valid audio sample rates for FLV files (according to ffmpeg). If converting to FLV and no sample rate is specified, and the source file rate is not one of these three, the script now assigns the best match automatically.

0.73 Image conversion now implements the "normalize" and "equalize" functions of ImageMagick's convert.

0.81 Videos can now be rotated (requires mencoder). Video-->frames conversion has been improved.

0.82 Video rotation is now two-pass and higher quality. Added image rotation, adjustments to ffmpeg which better retain original quality, added tests for curl/gawk/elinks(or links) packages, improved file-naming and progress-bar when converting multi-page PDF into GIF images.

0.83 Fixed 270 degree image-rotate and made adjustments when executed with no $args

0.84 The script will only complain about PATH if it needs to -- IF executed with no filename arguments

0.85 When converting multiple files using ffmpeg when notification method is set to quiet, fixed typo which caused 60-second delay between files.
