ZenCoder: A Video Encoding software for the Creative Zen 28 August, 2008
Few days ago was girlfriend’s 22th birthday, and I gave her a Creative Zen with video support… to let her be able to cross the world watching her favorites cartoons and youtube videos! 
During last nights I worked hard (yeah it was my first GUI ever, and first attempt with Gtk#) to give them another gift (it is a surprise), and now something is working: ZenCoder is ready!
ZenCoder is an usable frontend to mencoder, with a simple usage: just drop your videos on the Zen icon to start the conversion!
You can also choose the video (xvid scaled 320×240) and audio bitrate (mp3lame abr), skip conversions and view queued files.
Of course it supports RGBA colormap!
Yeah my girlfriend is both pretty and uses Linux, why I’m so lucky?
P.S.: If you have suggestions for improvements in the code feel free to poke me, this was really my first attempt in GUI programming, and it may have odd points. It also lacks of a good Makefile, an installation script and a .desktop entry. Please write me an email if you want to contribute.

Can you make package for Ubuntu?

How about turning this into a generic “re-encode for external devices” app?
Other obvious choices come to mind: PocketPC Phones (both 320×200 and 480×320), PS3 (format-picky), PSP…

@1:
I need a .desktop entry first and some kind oh installer… if someone wants to contribute
@2:
I had that idea but unfortunately 1) i have no devices to test the videos (DONATE!!! eheheh) 2) no time
anyway the project is open to anyone who wants to join it

Nice idea! However don’t such things already exist? PyTube?

Emmm… Could you give me your GTK and Emerald themes? Brilliants.

Super gift for your girlfriend

hey Cimi! Nice one!
My best wishes to your girlfriend
Please use http://www.launchpad.net and create a page for this project and a bzr branch; you could use the PPA feature (personal package archive) in order to create a repository with Ubuntu binaries.
Dad is not really a geek, but asked me a while ago to get rid of Vista from his new laptop and install linux on it; so i took the time and installed Kubuntu 8.04, running KDE 4.1
He has some mp4 device and he was always trying to install .exe applications for encoding vids…. he can’t really handle bash / terminal in order to use Mencoder….
Please allow this application to have/edit “profiles” (an user would set up multiple profiles for his devices) or something like that and have the applications develop a set of predefined profiles for as much as possible devices, also having some “quality” options for them.
Those are my 2 cents on how it could get better; would really like to use something like this; that would do so as well

Can it be used without dropping a file on that dialog? Maybe there’s a regular file picker under the ‘file’ item in the menu? That would probably be more accessible. Looks nice though.

@7: of course, but as I said I’m busy in the next month, an I don’t have a MTP to test the encodings. Someone could join, Gtk# is easy…
@8: yeah file menu should to it in the future

Aren’t we supposed to be doing this via HAL and gstreamer, much like audio transcoding is handled for USB mass storage players? If you plug a USB audio device into a system then run Rhythmbox, AmaroK or Banshee then you can just drag and drop songs in any format to it and they know how to Do The Right Thing via the information in /usr/share/hal/fdi/information/10freedesktop/10-usb-music-players.fdi . This is much more reliable and extensible than Yet Another Mencoder / Transcode GUI - the world’s already full of abandoned half-finished instances of those.

@Adam:
Except that gstreamer’s encoders and muxers hardly ever work for video. Well - Theora works but is not supported by most of the hardware.
I’ve written a similar program using gstreamer as its base and while it does produce xvid or h264 files… gst can’t play the xvid files it produces (if you drop sound they seem to work) and both my PS3 and my HTC smartphone mark the h264 files as broken (but they play all the other h264 files just fine).

@Patrys: While it is true that encoding so far has gotten less love in GStreamer than a lot of other things, it is getting better quickly. If you could file a bug and attach small file samples explaining whats wrong I am sure we could sort out things quickly. There is a summer of code mp4 muxer for instance which currently I am testing a lot myself to make sure it creates nicely working files.

Loving one purpose no-nonsence apps like this. Very rare in the “does it all for all the devices, codecs and resolutions” world of FOSS.
Good stuff!

Since you can’t test every single type of device there is why not add some sort of profiles. You could had a simple xml file (or other type) to a hidden directory like ~/.zencoder/profiles/ or something and show a drop-down list with current available profiles.
That could probably work instead of having to hard code them all in.

Great app!
I have a Creative Zen myself and was looking for a Mencoder GUI. This is perfect. Please consider making an Ubuntu package and hosting the app on Launchpad, like previously suggested, so that it gets more exposure.

Amazing.. My sister bought a Creative Zen X-Fi just yesterday, and I spent 4 hours of my life to bend her Ubuntu’s installation of ffmpeg + winff + mtp + gnomad2 to my will - and explaining to her how she should convert + transfer videos to her box.
Today I came across your blog while looking up about rgba, and I come across your little app. I tested it with an mp4 music vid - works straight out of the box. This would be a good fit in AUR in my opinion, and definitely should go on launchpad. If you could support multiple formats painlessly, so much the better, but as it is I’m definitely using it for the X-Fi, so much easier than WinFF
Thank you very much!
