PostProcessingLevel field of PB_INSTANCE
What is the PostProcessingLevel field of PB_INSTANCE? When is it used? It is used for all Theora's video or it is just for legacy support with VP3? Thanks -- Leonardo de Paula Rosa Piga Undergraduate Computer Engineering Student LSC - IC - UNICAMP http://www.students.ic.unicamp.br/~ra033956

Question about PB_INSTANCE fields
I'm trying to implement the dct_decoder's LoopFilter function in a FPGA. I need to know what is the maximum memory allocation size which display_fragment and recon_pixel_index_table points. These are fields of PB_INSTANCE structure that is declared in the codec_internal.h Thank you =========================== Leonardo de Paula Rosa Piga Computer Engineering Student Universidade Estadual de Campinas =========================== -------------- next part -------------- An HTML attachment was scrubbed...

theora_decode_init bug
I found a bug in theora_decode_init when I was implementing the decoder. theora_decode_init should be zeroing the theora state structure right? memset(th, 0, sizeof(theora_state)); // Erik -------------- next part -------------- An HTML attachment was scrubbed...

Theora MVect not defined in coding mode 0
Just wondering if someone can help me out... I'm testing the core of my decoder filter (win32)... and when i get into this function: tatic void DecodeMVectors ( PB_INSTANCE *pbi,ogg_uint32_t SBRows,ogg_uint32_t SBCols ) The decoding mode is 0. When it attempts to do these lines.... pbi->FragMVect[FragIndex + 1].x = MVect[1].x;pbi->FragMVect[FragIndex + 1].y = MVect[1].y; pbi->FragMVect[FragIndex + pbi->HFragments].x = MVect[2].x; pbi->FragMVect[FragI...

Theora Hardware: Integration with LEON is completed!
...on GSoC I think next step would be the to do a video controler. Then, we will have all the process on FPGA at final of my GSoC! I just was having a doubt. Is the UpdateUMV the last step of decodification? I saw on libtheora that after UpdateUMV there is the function PostProcess. void PostProcess(PB_INSTANCE *pbi) Is this function just a optimization for software? (that would be unecessary for hardware) Do you think that will be necessary more one module of decodification between UpdateUMV and video controler? Cheers, -- Andr?
