Nubeox en Linux

En este post explico cómo he conseguido reproducir contenidos de Nubeox Premium protegidos con DRM en Linux.
El mismo método debería servir para otros servicios problemáticos basados en Flash, como Wuaki o TotalChannel aunque no lo he probado.

Como tantas otras veces, el Wiki de Arch Linux ha sido de lo más útil. El problema parece ser que el DRM en Flash requiere HAL. Pero HAL hace años que está en desuso y desaparecido o reducido a la mínima expresión en la mayoría de distribuciones.
La solución pasa por instalar una versión especial de libhal, que internamente usa el sistema más moderno udisks, pero que proporciona los elementos necesarios para que el DRM de Flash funcione.
Se puede encontrar en https://github.com/cshorler/hal-flash, y una vez descargada habrá que compilarla y reemplazar el libhal del sistema si es que aún sigue ahí. Ojo, otros programas que aún dependan de HAL podrían tener problemas. Por suerte en mi caso (Debian Sid) libhal ya no era necesario.

En sistemas basados en Debian (Ubuntu, Mint…) se puede crear el paquete deb fácilmente:

$ sudo apt-get install devscripts build-essential
$ unzip hal-flash-master.zip
$ cd hal-flash-master
$ debuild -us -uc -b
$ sudo apt-get remove libhal1
$ dpkg -i ../libhal1-flash_*.deb

Además hay que eliminar la caché del plugin Flash:

$ cd ~/.adobe/Flash_Player
$ rm -rf NativeCache AssetCache APSPrivateData2

Tras seguir estos pasos, la reproducción de contenidos de Nubeox empezó a funcionar, tanto los canales en directo como las películas y episodios de series. No he probado los alquileres aunque imagino que funcionarán.

Relevation 1.3 released

I've just published an updated version of Relevation.

The main addition is support for the newer format of data files used by Revelation, plus a slightly better handling of international characters in the data file.

This is, however, a somewhat rushed and unpolished release to support the newer file format as soon as ready. As a result running the script in Windows is now harder, untested and most likely broken.
I plan to update it ASAP.

VCS 1.13.2 released

A new update of VCS with a couple bugfixes is available to download. Once again, if you had problems with the previous versions there's nothing new.

It fixes a bug when using MPlayer as capturer that could produce one more capture than expected. Thanks to Miya for reporting it.

Rooting a Minix

Index

Introduction

This article is about rooting a Minix set top box (a Neo X5 mini in my case), although it may be applicable to similar hardware, either from Minix or simply running on a Rockchip RK3066.

These devices are problematic simply because the default android tools won't detect them. Most solutions I've come across are reduced to "install Moborobo" or "run this fine one-click solution", which is of little help when you're running on a different OS or when something fails.

So this little guide is a lot more barebones, I've collected what steps should be followed and what ADB commands must be run instead of providing a script. Although it is written for Linux systems, most steps and all ADB commands will be the same on other systems.

Some of these steps might be unnecessary, but they will do no harm.

Setting up the device

By default the Minix won't even be visible by a computer, but that's easy to enable.

Just go into Settings → USB → Connect to PC.

Note this option will be re-disabled on each reboot.

You should also enable USB debugging:

Settings → Developer options → USB debugging

Now, plugging the device to the computer will make it detectable but ADB won't recognise it just yet.

ADB access

This section is tailored to Linux. Source: [1]

Enable normal users to access the device

Check that the device is detected:

$ lsusb
[...]
Bus 003 Device 025: ID 2207:0006
[...]

Devices like 2207:xxxx with no description are the ones this guide is about.

Add an udev rule to allow normal users to access the device:
Create a file in /etc/udev/rules.d/ named <SOMETHING>.rules with the contents:

SUBSYSTEM=="usb", ATTR{idVendor}=="2207", MODE="0666", GROUP="plugdev"

And reload udev rules:

# udevadm trigger

Enable ADB to recognise the device

You'll need to add the vendor id to the list of known android devices.
Simply add a line containing 0x2207 to the file ~/.android/adb_usb.ini:

$ echo 0x2207 >> ~/.android/adb_usb.ini

And stop ADB:

$ adb kill-server

It should now be able to recognise the device:

$ adb devices
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
List of devices attached 
ABCDE12345      device

Rooting procedure

You'll need the following:
su and busybox binaries
SuperSu apk

You can download a handy archive containing them from this thread on xda (post #2, file X5 Mini v4.2.2 Root.rar).

You might try running the included BAT if you're on Windows or continue with this guide for the dissection of it. The BAT contains commands you can copy-paste directly in the command-line, what follows are equivalent commands.

Note that, at least on the Minix, you'll already have root shell access. What's lacking is allowing "scalation" of privileges outside the shell.

Stage 1

$ adb shell
android# mv /data/local/tmp /data/local/tmp.bak
android# ln -s /data /data/local/tmp
android# reboot

The device will reboot. You'll have to re-enable "Connect to PC" in settings.

Stage 2

$ adb shell
android# rm /data/local.prop
android# echo "ro.kernel.qemu=1" > /data/local.prop
android# reboot

The device will reboot. You'll have to re-enable "Connect to PC" in settings.

Stage 3

$ adb remount
$ adb push su /system/bin/su
$ adb push busybox /system/bin/busybox
$ adb push SuperSU.apk /system/app
$ adb shell
android# cd /system/bin
android# chown root.shell su
android# chmod 6755 su
android# chown root.shell busybox
android# chmod 0755 busybox
android# cd /system/app
android# chown root.root SuperSU.apk
android# chmod 0644 SuperSU.apk
android# cd /data
android# rm local.prop
android# rm tmp
android# mv tmp.bak tmp
android# reboot

The device will reboot and you should have root access.
Launch the SuperSU app to check. It will probably want to update the su binary, let it do so.

If SuperSU doesn't seem to find the su binary, check it's there and that it has the appropriate permissions:

$ adb shell
android# cd /system/bin
android# ls -l su
-rwxr-xr-x root     shell       91980 2012-06-27 21:50 su  # ← Incorrect permissions
android# chmod 6755 su
-rwsr-sr-x root     shell       91980 2012-06-27 21:50 su  # ← Correct permissions

And re-run SuperSU

Pipelight: Silverlight en Linux

¡Por fin! Una solución para poder usar sitios que requieren Silverlight en Linux sin problema (en la mayoría de casos, al menos).

Hace tiempo que Moonlight está abandonado, muerto y enterrado. Moonlight era el engendro de Novell y Microsoft que implementaba Silverlight (pero no todo) en Linux, y que nunca fué una solución demasiado buena. Microsoft como casi siempre no tiene ningún interés en soportar Linux (aún gracias que soportan Mac OS X, aunque sea por poder decir que .NET y Silverlight son multiplataforma).

Reproductor de video sobre Pipelight

Pipelight en acción

Parece que desde hace algunos meses tenemos otra solución viable: Pipelight. No es una solución bonita, pero permite tener un "plugin Silverlight" oficial en el navegador estándar que queramos usar y funciona, que no es poco.
Tras el telón usa Wine y unos cuantos hacks para poder correr el plugin para Windows. Funciona tanto en x86 como en amd64 y dentro de lo que cabe no es demasiado difícil de instalar, hasta proporcionan paquetes binarios para multitud de distribuciones.

Como comparación, la versión "usable" de Moonlight que tenía instalada corría el test Balls Animation entre 30 y 60 fps mientras que pipelight me lo mueve a 200.
La reproducción de video en Yomvi, cuyo cambio de Flash a Silverlight me había desesperado, es bastante fluída.

Las instrucciones de instalación están en inglés, aunque son bastante fáciles y casi todo consiste en ejecutar los comandos que muestran.

Relevation 1.2.1 released

I've just published a very minor update to Relevation.

It just fixes the previously broken minimal-GUI and adds support to build RPMs directly from the tarball.

Copying EXIF metadata between files

This tip might be useful for those cases when an editor ignores a photo meta-information (which seems fairly common in phones).

$ exiftool -TagsFromFile source.jpg target.jpg

or

$ exiv2 ex -e e source.jpg  # Extraction. Also $ exiftool -exif -b source.jpg > source.exv
$ mv source.exv target.exv  # Names must match
$ exiv2 in -i e target.jpg  # Injection

Relevation 1.2 released

I've just published a new version of Relevation.

The biggest change is that it can now combine search terms, useful to reduce the number of results when you've got multiple similar logins alike. Check the updated man page for more details.

There's also a couple of small but important bugfixes.

See the changelog for the full list.

It will now handle wrong passwords a bit more gracefully and it's also easier to use on Windows now.

New tool release: Quick File Share for Android

I've published my second android app, a bit more useful than the first one (and also more prone to be a source of problems :P).

Quick File Share is meant to ease file sharing between devices by using a Wi-Fi network. Sharing content between Androids sucks: you can use bluetooth for a painfully slow experience or use email or cloud storage, with the unnecessary upload (which is also extremely slow for most people), while NFC is just a fancy way of triggering a bluetooth transfer; and that's about it.
Wi-Fi Direct (aka Wi-Fi P2P) finally emerged as a solution, but that requires discrete hardware that only newer devices have.
Meanwhile, if the devices are connected to a Wi-Fi network, than speedy, wireless, and already set up connection can't really be taken advantage of by default. That's the spot this app helps in filling, and it's certainly not the only option, but I couldn't help trying.

Select a file to share, and a temporary webserver will be started on the "sending" device. It will display a QR code and an HTTP address, so that the receiving device(s) can receive the file by just typing the address in a browser or scanning the code (scanning the code will also trigger the browser). The actual transfer is always over HTTP, so you can actually receive the file on essentially any device with network access.

What's the catch? There's always a catch. At least for the time being, the two devices must be connected to the same network. There are other tools on the marketplace that help the receiving device connect to the same network as the sender, but I didn't like that operation too much, so I preferred this way of operation.
