Hi, I have a question about the format of Theora bitstream header. It seems to me that there are differences between the specification[1] (version 2004 Oct 1) and its reference implementation in libtheora 1.0alpha3 released at 2004 Jun 1. I mean that... please refer to Section 6.2 'Identification Header Decode' in that specification[1] and the function

Is there a project preset I have to change? or something else? I can manualy add to ogg buffer like oggpackB_write(opb, 55, 8) ok, so it's not the buffer that's the problem but the part where it's bit-shifting the second line in the function. I have taken the code from Theora library as it's closer to using libogg2 than vorbis library. Vorbis is working ok in my application but have yet to include t...

Hi, I am making good progress on understanding, documenting, and re-implementing VP3. I have found some more deadwood in the decoder code and I just wanted to verify that it really has no place: * Version 3.3 tables: There are 2 sets of VLCs: One for v3.1 and one for v3.3. The v3.1 set is always selected. Are the v3.3 tables in production, or will they ever be? * DC Search Points: VP3

Hi all, I'd like to force rematerialization by extending live intervals. For example: %vreg1 = opa %vreg2, %vreg3 ; RClassA:%vreg1, RClassB:%vreg2, RClassB:%vreg3 ... somewhere between --> %vreg2<kill> and %vreg3<kill> .. %vreg4 = opb %vreg1 ; RClassA:%vreg1, RClassB:%vreg4 In my case, %vreg1 is not spillable and I'd like to extend vreg2 and vreg3 live intervals to get "opa" rematerialized. If I understand correctly, the InlineSpiller only rematerializes if all the operands values of "opa" reach &quot...

Hello! First of all a question: When you make the encoder tables (ie: mode_e.h) do you use the mapping0_forward function? Because you made the encoder tables, and after this you did a minor correction in the final beta4 ... (this correction was: additional[0]=fabs(additional[0]*scale); in the mapping0_forward function) (I see this was a bug, and the modification was correct, but this correction

...ode book tree till it hits a leaf node which is nothing but the entry number. If we consider our floor 1 Y value example , this entry number is directly being used as the Y value. Here is an extract from the tremor code for the same "if((fit_value[j+k]=vorbis_book_decode(books+book,&vd->opb))==-1)" where vorbis_book_decode is returning an entry number. If this is correct the code books constructed for decoding of the floor at the encoder should have as many entries as the maximum value of the floor 1 Y value can take (seems to be 256 ) . In the case of the residue computation th...

Tim's proposal seems reasonable but it conflicts with the FLAC documentation that says the channel ordering follows SMPTE/ITU-R recommendations. I think we may be butting up against an area where the standards aren't clear. ITU-R BS.2159-4 (http://www.itu.int/dms_pub/itu-r/opb/rep/R-REP-BS.2159-4-2012-PDF-E.pdf) doesn't define a 7.1 layout but simply diagrams several possibilities on page 27. DTS-HD seems to specify 7 different possible 7.1 layouts (http://www.scribd.com/doc/17630423/21/Channel-Layout). I think my preference for the Apple/Core Audio layouts is kno...
