| Hello everyone,
| | == Introduction == |
| | | This is the Debian kernel. It is roughly equal to a kernel shipped by Debian Linux in their releases. Ebuild now support the <code>binary</code> USE flag. The aim of this ebuild is to have support for near all possible hardware and users shouldn't really dig into configs, aka "install and forget". Daniel has added a special config-extract command which can be used to list all available official Debian kernel configurations, and generate them from the Debian files included with the kernel. |
| Funtoo Linux has amazing support for all different kinds of audio, video and graphics formats, as well as media devices that can be enabled via USE flags -- but let's face it -- with all this flexibility has come a certain amount of complexity in enabling all the USE flags you need for a particular application. I've tried to address this by [[Funtoo Profiles|enhancing the profile system]] to include flavors and mix-ins, and creating a {{c|media}} mix-in that enables stuff that a lot of people will want, which is auto-enabled in the {{c|desktop}} and {{c|workstation}} profile. But I always knew that this, while an improvement, was not the final word on media support in Funtoo Linux, and that we needed to do more work here.
| | == Usage == |
| | | <console> |
| Recently, thanks to assistance from [[User:Mgorny|Michał Górny]], we have been able to implement my design for second-generation media support to Funtoo Linux! Here's how it works. Rather than have a single mix-in called "media", we now have finer-grained categories, and the existing {{c|media}} mix-in has been upgraded to pull in a subset of these categories. Let's look at all the new mix-ins:
| | ###i## echo "sys-kernel/debian-sources binary" >> /etc/portage/package.use |
| | | ###i## emerge debian-sources |
| === Media Device Mix-ins === | | ###i## nano -w /etc/boot.conf |
| | | ###i## boot-update |
| Media device mix-ins have been created to support media devices, including external and portable devices, and associated low-level hardware support and hardware-focused codecs. Media devices have been categorized into audio and video categories, and consumer and professional categories. "Consumer" devices are those devices that regular desktop users might typically use, while "professional" devices are those that professionals, hobbyists or enthusiasts would typically use. Here are the new mix-ins for media devices:

| <tr><td>{{c|mediadevice-base}}</td><td>Common, universally-supported media devices, like IEEE-1394 (Firewire), CDDA, CDIO. Other mediadevice mix-ins have this as a parent.</td></tr>

| <tr><td>{{c|mediadevice-video-consumer}}</td><td>Consumer video support, such as DVD, Blu Ray, V4L</td></tr>
| |
| <tr><td>{{c|mediadevice-video-pro}}</td><td>Pro video support, such as dv, dc1394.</td></tr>
| |
| {{TableEnd}}
| |
| | |
| === Media Format Mix-ins ===
| |
| | |
| Media format mix-ins have been created to support media formats for reading, writing, encoding and decoding images, audio and video. They have been organized into a "common" collection, for popular formats, and an "extra" collection, which is intended to include "everything else". Let's look at the new mix-ins:
| |
| | |
| {{TableStart}}
| |
| <tr><th class="active">Mix-in</th><th class="active">Description</th></tr>
| |
| <tr><td>{{c|mediaformat-video-common}}</td><td>Common (ie. popular) video formats.</td></tr>
| |
| <tr><td>{{c|mediaformat-video-extra}}</td><td>More esoteric video formats.</td></tr>
| |
| <tr><td>{{c|mediaformat-audio-common}}</td><td>Common (ie. popular) audio formats.</td></tr> | |
| <tr><td>{{c|mediaformat-audio-extra}}</td><td>More esoteric audio formats.</td></tr>
| |
| <tr><td>{{c|mediaformat-gfx-common}}</td><td>Common (ie. popular) graphics formats.</td></tr>
| |
| <tr><td>{{c|mediaformat-gfx-extra}}</td><td>More esoteric graphics formats.</td></tr>
| |
| {{TableEnd}}
| |
| | |
| === How to Use Them === | |
| | |
| Our existing {{c|media}} mix-in still exists, and is still pulled in by the {{c|desktop}} and {{c|workstation}} flavors automatically. It now includes the following parent mix-ins:
| |
| | |
| * {{c|mediadevice-audio-consumer}}
| |
| * {{c|mediadevice-video-consumer}}
| |
| * {{c|mediaformat-audio-common}}
| |
| * {{c|mediaformat-gfx-common}}
| |
| * {{c|mediaformat-video-common}}
| |
| | |
| In addition, there is a new {{c|media-pro}} mix-in which needs to be enabled manually, which pulls in the following mix-ins:
| |
| | |
| * {{c|mediadevice-audio-pro}}
| |
| * {{c|mediadevice-video-pro}}
| |
| | |
| So typically, you would enable the {{c|desktop}} or {{c|workstation}} flavor, and if you need professional hardware support, you'd also enable the {{c|media-pro}} mix-in. If you needed any additional media formats support, you could enable one or more of the {{c|mediaformat-*-extra}} mix-ins to add the formats you needed. Of course, it's possible to enable only the specific mix-ins you need, and also complement these mix-ins with specific USE variable settings you might require.

| |
| | |
| === Conclusion ===
| |
| | |
| Going forward, these mix-ins can be maintained to include new USE flags that are created, providing an easy way for people to enable the features they need without looking through long lists of USE variables. I hope you like the new system!
