The user side libraries use this ‘driver’ to communicate with the GPU and tell it what to do.
#How long to get raspberry pi codecs drivers#
One of these drivers is the interface from the user space libraries to the GPU. There are a few drivers for the SoC which are linked in to the kernel, these are GPLed and hence OSS. There is no GPL issue here, these are user side libraries not linked in any way to the kernel. It’s worth noting there are no other SoC devices with a similar graphics performance that are open source. Since the vast majority of people simply use libraries such as these, it was deeded a trade off worth making to get the high graphics performance. The Foundation has no control over the closed nature of these libraries. As stated above, the host side libraries for the graphics acceleration are closed source and are provided by the SoC supplier. The Open/Closed source debate can become quite heated, as those perusing the comments and forums may have noticed.

We should be able to support VP8, MJPG and Theora, as I believe they are license free. We are restricted due to licensing what we can support.

It can software (but still vector accelerated) decode VP6, VP7, VP8, RV, Theora, WMV9 at DVD resolutions. There are non-licensed Codecs such at MPEG2, VC1 etc, but for the moment they will not be accelerated by the GPU.ĭom adds: As an aside, the GPU can hardware decode H264, MPEG1/2/4, VC1, AVS, MJPG at 1080p30. Codec licences have quite an impact of the cost of the device which is why there are only two at this stage. Two licensed codecs will be provided at launch, MPEG4 and h.264. There is loads of information on Wikipedia and the Khronos website on these API’s. All these libraries are as supplied by Broadcom, the SoC (System On Chip) provider. OpenMAX IL does not have a standard API at this stage, so is a custom implementation. The first three adhere to the standard Linux library API’s, so should be a straight forward swap in for applications that use them. OpenMAX defines three layers, this is the IL layer, which provides an interface between media framework such as Gstreamer and a set of multimedia components (such as codecs). OpenMAX supplies a set of API’s that provides abstractions for routines used during audio, video, and still images processing. Again, defined by the Khronos Group.ĮGL is an interface between Khronos rendering APIs such as OpenGL ES or OpenVG and the underlying native platform window system. OpenVG is a 2D vector drawing library, also commonly used on desktops and embedded systems. OpenGL is a 3D library, very commonly used on desktops and embedded systems. The libraries that will be available are : Any distribution will need to supply a set of closed source libraries that give access to the GPU acceleration features. It won’t be comprehensive – I am sure that for some it will generate more questions than answers, but I hope it will be of help.įirstly, libraries. This short post will try and give people some idea of what will be available at or around launch time. There have been quite a few questions in the forums and on the comments about what libraries will be available, what codecs, what is open source etc.

He works for Broadcom as his day job, and knows the BCM2835 as well as anybody you will also have seen him posting in our forums and spanking trolls in our blog comments. Here’s a post from JamesH, one of the team working on the Raspberry Pi’s software.
