Re: A plea to the Foundation re. MPEG-2

I've been watching this thread with interest http://www.raspberrypi.org/phpBB3/viewtopic.php?f=29&t=5641 about software decoding of MPEG2 at SD resolution. Is this a solution that is likely to reach fruition before a Hardware Decode solution being licensed? I am pondering if SD MPEG-2 decoding in so...

Re: A plea to the Foundation re. MPEG-2

I would use MPEG-2 decoding quite a bit, primarily for 1080i decoding on OTA terrestrial TV broadcast streams here in the States. In the UK "Freeview" (SD OTA terrestrial digital TV) uses MPEG2, but "Freeview HD" (HD OTA terrestrial digital TV) uses H264. Does the US use MPEG2 for both? Yes, the US...

Re: A plea to the Foundation re. MPEG-2

IF there is a small dongle route, could it hang off one of the low level interface buses? Like the SPI or I2C?

Re: A plea to the Foundation re. MPEG-2

I do not care either way as none of the projects I have in mind for the Pi involve video encoding, but it occurs to me that: In light of the rate at which the patents covering MPEG-2 are expiring, the--as I understand it--low license rate per machine at moderately high volumes (I think someone indi...

Re: A plea to the Foundation re. MPEG-2

Why are you watching DVD as MPEG2? I always rip to H264 - much better compression (about twice as good for same quality) as MPEG2. Or are you playing direct from DVD? I used this quote because I didn't think jamesh would think I was picking on him. I would hope that my advocacy for MPEG2 is not per...

but also understand that if it were as simple as X, then they would have done X already :-P This is the thread about using the GPU to hardware-decode MPEG-2.

Re: A plea to the Foundation re. MPEG-2

...there seems to be a bunch of antipathy around folks expressing that MPEG2 as a requirement. So perhaps if I explain, then it will either make sense, or provide a insightful counter-argument that convinces me to do/want something else. I don't think it's antipathy as such, just an expression that...

Re: A plea to the Foundation re. MPEG-2

Given the pragmatic decisions evident elsewhere on the Pi board I can only assume that the inclusion of a GPU that seems overspecced for a budget educational device was to act as a carrot. I'm sure that some kind of challenge / response licencer and software validation layer could be set up, but am...

Re: A plea to the Foundation re. MPEG-2

I suspect that any licensing scheme would have to be implemented in the binary GPU blob to be trustworthy enough to work. Even still, coding of this type usually requires specialized knowledge to prevent easy circumvention. If there was a 'model c', the driver would have to be 'unfoolable'. There is...

Re: Mpeg 2 poll

As far as I see it, the only sane option would be to bundle mpeg2 licensing with every pi sold, and take the hit, in the same way that's happening for H.264. So roughly how much is h.264 licencing currently costing per Pi ? $2 ? Can't remember offhand, it was mentioned in one of the many previous a...

Re: A plea to the Foundation re. MPEG-2

A Raspi could, with the right software (not available - just an example), transcode SD MPEG2 to H264 in real time (if I worked the numbers out right!). With the right HW add on it can encode 1080p30 H264 from an HDMI video stream. Can't be that an expensive an operation... I reckon there might be a...

Re: Mpeg 2 poll

I appreciate all these adding up of costs to compare the Pi to a Roku, but I think that they miss the point of the Pi -- you can do what you want with it and are encouraged to do so. Sure you might be able to do one thing on a roku and maybe hack an ATV and do another, but none of those product prod...

Re: A plea to the Foundation re. MPEG-2

Where on the priority list does making these codec's licensable and purchasable fall? Reading the various forums, the sentiment seems run from "we could do this" to "this isn't something we want to spend time on".

Where on this fit in the time horizon?

Re: A plea to the Foundation re. MPEG-2

That's quite correct. Difficult to reverse engineer a binary when you don't even know the instruction set. Also, the GPU has built in hardware for DRM stuff, so that a possible avenue for the required encryption. Is there anything uniquely identifiable on the RPi that could be used for a keyed lice...

I appreciate the thought, but I don't want to sell anything on ebay ever again. Also, I can't pretend I'm about to do ...

Re: Aquire MPEG2 license

Having gotten my Pi just last week, I had quite a bit of fun building a toolchain for it and setting it up and configuring it. That it doesn't handle the formats of my BD and DVD media is fairly disappointing, but I should have read the specification more closely -- my bad. It won't make it into any...
