Hi The newest cvs let's mplayer segfault: ... Opening video decoder: [theora] Theora/VP3 Segmentation fault I don't get any infos more :( A gdb backtrace don't work. (mplayer is compile with --enable-debug=3) When will the encoder_example implemented in mencoder ??? Would be nice because the yuv-data is soooo big on the HD ;) Jens --- >8 ---- List archives:

Hi Again, the newest theora cvs prevents mplayer from compiling: gcc -c -O4 -march=pentium3 -mcpu=pentium3 -pipe -ffast-math -fomit-frame-pointer -D_REENTRANT -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -I../loader -o demux_ogg.o demux_ogg.c demux_ogg.c: In function `demux_ogg_open': demux_ogg.c:626: warning: passing arg 2 of `theora_decode_header' from incompatible pointer type

I've got my encoder working now... and i put a proeprty page interface to allow the user to set a few encoding paramters to start off with... but changing the paramters doesn't seem to make barely any difference... These are the defaults i'm using... mTheoraInfo.target_bitrate=400000; mTheoraInfo.quality=30; mTheoraInfo.dropframes_p=0; mTheoraInfo.quick_p=1;

Greetings, I was on IRC about 7 hours ago and suggested that the FAQ be updated slightly. Rather than sit on my ass and complain I figured I'd ask a few people, and see if the idea was worth the time. Here's what Ive started with: http://www.dimension.net.nz/theora.html I'll be adding to it over the next 24 hours - mostly in the area of Playback and Encoding. Just threw it together

Hi I was surprised with size of Theora files and thought of feedback. Following 1minute duration Theora and Xvid files were made from a y4m file. The resolution is 1280x720: 1. Xvid 17MB 2. Ogg/Theora Q7 31MB 3. Ogg/Theora Q8 38MB 4. Ogg/Theora Q9 49MB 5. Ogg/Theora Q10 61MB The Xvid file was made using mencoder by 2 passes with following options:

...Vorbis packets to drift the granulepos to compensate for A/V sync? That would mean that granulepos does not represent the number of actually played samples any more. Seems like an ugly hack. Any other ideas?

All, Thanks to everyone who's been testing the recent releases. Some of you pointed out some real problems with the smoothness of the rate control on a few clips, so now, ten days later, we have some more fixes for you. I give you the beta3 version of the "thusnelda" rewrite. In addition to the smoother rate control, there are a few minor bug fixes and build polishes. Please give

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, I just want to know whether it would be possible to play ogg-theora videos on my favourite Handheld, the GP2X. For those of you who don't know the GP2X yet there's much information about it on Wikpedia or on http://wiki.gp2x.org/wiki/Hardware_Documentation . To make it short, its an ARM-based Handheld which is able to play Xvid and DivX

hi, i was trying to enable the mmx code on mac os x. to get to that point one has to replace some inline assembler code: .balign 16 -> .p2align 4 and replace .rept .. .endr with #defines. but to makes things more complicated apple's GAS does not support movsx instructions and thus the following line does not work: " movsx %%di, %%edi \n\t" [ more details at

Hi I'm evaluating Theora for a video communication system and would like some info as to what the following struct members (from the theora_info structure) do and what values one should pass to them: If there is some documentation somewhere that I've missed, please direct me to it. ===== Extract from theora.h ===== int quality; int quick_p; /* quick encode/decode */

...rrors etc.). Not sure whether the patch works in all cases, as I don't have much experience with libavcodec... Maybe command-line switches for tuning/disabling the A/V sync algorithm might be a good idea?

Hi, I have multiple ogg/theora files, with different bitrate. That is the big problem, because I want to broadcast them using ezstream/icecast and the connection between ezstream and icecast is always lost when switching between files. They have the same resolution but different quality. Is there a tool to concatenate/normalize several files to a big homogeneous one? -- A powerfull GroupWare,

Hi everyone, I've just made the first public release of some new *experimental* codec work I've been doing (part of the vague Ghost project) with help from Monty and Timothy. This is mainly intended with developers with DSP knowledge, not for doing anything useful with it (but it does encode and decode already). Also, the main idea is *not* to replace either Speex or Vorbis, but to code

Hey all, I'm working on a media-database art project that basically stores a bunch of sound and video files, which are then navigated based on meta-data. I'm not sure where to start asking these, questions, here seemed like a good start. So I was thinking I should use an open format, like ogg/vorbis/theora. I also thought, will all that coll meta-data stuff in ogg I should be able to

Hello. I'm trying to encode an Ogg Theora file from an unencrypted dvd using mplayer and encoder_example. I set up named pipes stream.wav and stream.yuv. I then run: mplayer -ao pcm -aofile stream.wav -vo null /dev/dvd & mplayer -vo yuv4mpeg -ao null -nosound /dev/dvd & encoder_example -v1 -a 1 stream.wav stream.yuv > lec1.ogg but I get the following error: File stream.wav is

Hi, I decided to try Theora and encoded a PAL DVD. I was very pleased with the result. It's better than "DiVX" for the same bitrate, I think, and the audio is clearly superior to MP3 audio. However, I'm having serious troubles encoding NTSC DVDs and getting the video and audio durations to match. I read some messages on this list about such problems and so what I am doing
