similar to: AW: How to do Theora playback efficiently ?

Dear theora developer community, currently I'm working on a simple Theora player for Windows. But the code in the player_example.c seems not to have the performance of other implementations like the Direct Show filters by illuminate. In the example player, all important things are done in one thread: decoding the next vorbis or theora packet(s) and reading from the physical stream (+ split

It seems to me that running ogg_sync_pageout doesn't automatically advance the page. This is good if you haven't worked with the given page, makes coding somewhat easier. However, when does a page advance. Is it after a call to ogg_stream_pagein? On a side note, I need to do seeking on top of libvorbis, I'd love to use vorbisfile but sadly I can't. Is there a reasonable way to

Hi all, I'm mixing logical streams at the page level. One stream has vorbis data, the other has my own data. Do I need two ogg_sync_states or just one?

I guess I'm missing something since the following minimized test case is failing: >>> #include "ogg/ogg.h" main() { ogg_sync_state the_ogg_sync_state; ogg_sync_init(&the_ogg_sync_state); ogg_sync_destroy( &the_ogg_sync_state ); } >>> $ gcc -g -logg test.c $ ./a.out *** glibc detected *** ./a.out: munmap_chunk(): invalid pointer:

Hopefullly this is once again something trivial I'm missing. I'm still trying to figure out how to pull a part a stream. I get two out the three theora headers I can see in the file (http://v2v.cc/~j/theora_testsuite/320x240.ogg) if I use the buffer in the page struct and nothing usable if I try to use the packet structs. Hopefully this is once again something something trivial I've

Hi, I've eventually released the first version of my rendering library for Kate streams, and I've recently been hacking away at adding it to liboggplay. That was the missing "overlay" mode to the browser_plugin patch I sent a while ago. Now, I'm not too sure how to expose those overlays to liboggplay users: the obvious solution is to add a RGBA video type, and expose the

Hi, A week or two ago Viktor Gal migrated the liboggplay source repo to git.xiph.org, and this week I moved the liboggz and libfishsound repositories. You can see the git repositories available via gitweb at http://git.xiph.org/ I wrote some brief news about the move, and instructions for getting the code: http://blog.kfish.org/2009/04/liboggplay-liboggz-libfishsound.html Thanks to Ralph Giles

Is anyone working on liboggplay, and if so, is there any plan to support keyframe-based seeking? I found this, but seems to me that the feature ought to be part of liboggplay: http://pearce.org.nz/2009/05/video-seeking-improvements.html Is there a more appropriate list to post to regarding liboggplay?

Do we want to do summer of code 2010 this year? The deadline to apply as an organization is Friday the 12th. I know we have not had very high success rate, but it seems there are plenty of small well defined focused area projects that could use some love. Just the ogg-index-migration list for example: http://wiki.xiph.org/index.php/OggIndex-Migration I think we should submit an organization

Okay, how do I drop a changeset/patchset/tag for you folks from SVN? At this point, I have written three examples of how to use the basics of the ogg streaming and decoding in Tremor. I heartily welcome any suggestions, improvements and corrections that you can point out in the code. The examples required me to make some small modifications to the main tremor library. However, the changes

I need to be exposed to a way of seeking theora streams. I have repeatedly found the same question asked on a different forums but could not find an answer. I'm working on a game and started integrating video with theora, the sound works just fine with ogg/vorbis(i find it easy to seek using ov_raw_seek for audio files). Could someone please point me to some example/code of how can i seek with

Hey, ::: I'm sending a patch for liboggplay for comments. It adds - runtime cpu extension detection - fixed mmx implementation - added sse2 yuv to rgb conversion - added a faster vanilla implementation ::: currently it works fine on unix systems, the MSVC implementation needs a bit of a hacking, but basically you get the concept of the refactoring. If you have any

After creating a simple decoder for theora using liboggz i started profiling. As someone else stated in the lists the conversion from yuv 2 rgb takes a significant time. I decided to go on the way of SIMD not shaders because SIMD is supported on a wider range of computers. I managed to strip out the yuv 2 rgba conversion code from liboggplay but it seems i am missing something. It runs but the

Hello, currently I'm working on a vorbis based encoder that adds multiple single wave sounds into one vorbis stream (and put every sound in one or more ogg pages). During the process an index is written in an extra file so later you can locate a sound's position easily by a file position and length value. The problem is the sample-exact separation between those encoded wave sounds: If I
