Hello, I am using theora in an application, but it does not work, I was looking to know why, and since I have one application using theora, I checked the difference between the two executions. And it seems that the function *_theora_decode_header_* does not have the same issue in the two application, but I read the same file... the difference is on the _m_theoraInfo_, in the first application ( which work ) the offset_y is equal to 4, and in the second application (which does not work) the offset_y is equal to 0. that's the same fi...

I'm interested in ignoring the audio stream in a theora encoded file. My first attempt was to remove the test for vorbis: /* identify the codec: try theora */ if(!theora_p && theora_decode_header(&ti,&tc,&op)>=0){ /* it is theora */ memcpy(&to,&test,sizeof(test)); theora_p=1; }else if(!vorbis_p && vorbis_synthesis_headerin(&vi,&vc,&op)>=0){ /* it is vorbis */ memcpy(&vo,&test,sizeof(t...

..._state th; theora_info_init (&ti); theora_decode_init (&th, &ti); theora_clear (&th); theora_info_clear (&ti); } segfaults. The cause is that theora_decode_init() expects a theora_info structure which was previously initialized by passing actual bitstream data through theora_decode_header(), as documented in theora.h: /** * Initialize a theora_state handle for decoding. * \param th The theora_state handle to initialize. * \param c A theora_info struct filled with the desired decoding parameters. * This is of course usually obtained from a previous call to *...

ok now I see why we need another packet in the header. The first one is basically for ID purposes (theora_decode_header()). I've jammed my huffman trees in there but it sucks because I need them later on when I actually build the huffman tree structs (theora_decode_init, calls InitHuffmanSet()). At that point the original header packet is gone so I've been keeping it around in a buffer. Gross!! Someone...

Hello, I am programmer working on a product which integrates Theora. I have a question regarding the memory use on some of the internals of Theora. Is this the right forum for this question, and if not, does anyone know where an appropriate place to ask is? Thanks Sam -------------- next part -------------- An HTML attachment was scrubbed...

...and libasound (and libogg/libvorbis and whatever other libraries I've missed) might be helpful, since the example player(s) are apparently currently the only way to examine the encoded Ogg Theora files (MPlayer support for Ogg Theora seems to be broken by the addition of the theora comment in theora_decode_headers). Having the . configure script print a warning ("missing static version of libXXX.a") would probably be helpful as well. Finally, now that I've got the encoder and decoder working, I wanted to grab something off of the Prelinger archives (so that it's redistributable) and ge...
