Transcoding for mobiles

transcode-iconThere are times where I need a few films on my mobile for my son to watch. For my particular mobile “Galaxy Gio” the constraints for hardware acceleration is 360p as anything bigger will cause it to switch to software which is slower and sometimes a slideshow. For the uninitiated, 360p means either 480×360 at 4:3 ratio (your old TV) or 640×360 at 16:9 ratio (your HD TV).

First we need to cleanup our file names and sometimes ‘rename’ doesn’t work properly. We list all files and separate them by commas and then parse line by line to first remove everything between () and then everything between []. We then move from the old name to the new name.

Upgrade Samsung Galaxy Gio to CyanogenMod 10.1

After about a year of Gingerbread (2.2.3) and CyanogenMod (7.2), I thought it was time again to look at further upgrades to my Galaxy Gio. This was apparently enough time for developers to work out problems involved in dealing with Ice Cream Sandwich (4.0.x) and Jelly Bean (4.[1-2].x) such as no ICS (or greater) libs and codecs from Qualcomm for the MSM7x27 family of chips for hardware acceleration.

Thanks to the Samsung Galaxy Gio community at xda-developers, we now have CyanogenMod (10.1) which is based on Jelly Bean (4.2.2) that is usable for every day use. There are a few things that I’ve noticed that are not perfect, but it is a fully usable ROM. Before you do anything suggested below, it is wise to first backup anything you think important and not just to your SD as it will be overwritten to support an extra ext4 partition that can be used to store your applications and save valuable space. Make sure your SD is rated 6 or better.

Upgrade Samsung Galaxy Gio to CyanogenMod 7.2

Going from 2.3.x (Gingerbread) to CyanogenMod 7.2 (Gingerbread) is surprisingly simple unlike upgrading from Froyo. I’ll go into more detail below, but there are two necessary bits: an updated recovery rom and a custom (non-official) CyanogenMod rom. This version of CyanogenMod is specific to the Samsung Gio.

Before upgrading your Samsung Gio, you must first be running at least 2.3.x (Gingerbread) before continuing because of the use of ext4 instead of rfs. Please follow my upgrade guide “Upgrade Samsung Galaxy Gio from 2.2.x Froyo to 2.3.x Gingerbread” first.

Warning: Caveat emptor – While I used to this process to update my phone, I take no responsibility if you brick your phone. Be sure to back up anything you wish to save, this procedure works best when your Gio is fully wiped of data.

Upgrade Samsung Galaxy Gio from 2.2.x Froyo to 2.3.x Gingerbread

Going from 2.2.x (Froyo) to 2.3.x (Gingerbread) is an involved process as there is always the fear that you will ‘brick’ your phone. This fear usually keeps most people away from upgrading. I’ve found a process, with Google’s help and trial/error, that managed to get process done painlessly and without a dead mobile.

Here is a little back story: I was lucky enough to come across the Galaxy Gio in a bad state while at work. The mobile would turn on, give the Samsung logo then black-screen and would not boot any further. It wouldn’t have made a good paperweight but if I could salvage it, it was mine.

Note: This process is a requirement before upgrading to a Cyanogenmod release.
