Ogg Theora Update
I'm suprised this isn't on the front page and that there hasn't been any threads on the subject. But I imagine this is why
Quote:
As this is an alpha release we are again providing sources only. See the files section of downloads. This version requires libogg 1.1 or later and libvorbis 1.0.1 or later.

these are indeed great news!

the idea behind theora is simply fantastic (like vorbis) and i think we should cover the developments about this much more on doom9

maybe the reason why there is not much talk about it is simply because there are no compiles for testing available
so can someone of our compiler pros (maybe athos) plz make a nice compile for us

Here you go

It include a encoder, a player and a transcoder.
I didn't try it yet, coz i'm still figuring how to have YUV4MPEG2 video file for input

well i remembered that i had compiled ffmpeg not so long ago

so using : ffmpeg_g.exe -i test_th.avi -f yuv4mpegpipe test_th.yuv i get what i wanted.

Unfortunatly, the player crash badly on any ogg file producted, so i can't judge on video quality atm

for a 23.23sec video, 558 frames, 320x240, no audio :
- size : 1.11Mb
- speed : 35.61 sec (~15fps)

now if someone have some idea for playback ...

Ok, i got the player working, when compiling everything in Release mode (there was some debug things in the decoder which was stopping the process).

I included the dump utility too, here the new build :
http://moodub.free.fr/theora_tools-1...ease_build.rar

And for the one who want a ffmpeg build to make yuv files :
http://moodub.free.fr/ffmpeg_win32_cvs20040223.rar

As for quality, i'm very pleased, although it was very quick, it looked fine (well the source wasn't that great )
As for speed, I can't decode flawlessly (some lag) a 640x480 video + vorbis audio, with my 2300mhz Athlon XP.

it only output ogg

and it isn't compatible with the actual ogm MPC internal splitter from Gabest...i leave the interpretation to you :whistle:

oh, i found that it's lagging, not because of a too slow decoding (40% in 832x480), but most likely because of some synching problems when there is audio.

One would have hoped that you could pipe the yuv from ffmpeg, but it doesn't look like it.

mplayer seems to play the created streams file. Can also I guess encode to theora, but I think only as an AVI?

i got piping working \o/ so now you can test big file without a lot of extraspace

just use :
Code:
ffmpeg_g.exe -i test_th.avi -f yuv4mpegpipe - | encoderwin.exe -a 5 -V 1000 -o test_th.ogg test_th.wav -
the "-" tell to output to stdout and to take stdin as input.... i can believe it was that silly :/

well we were very lame, because latest ffdshow build with ffvfw support Theora Alpha3 for encoding

So you can put Theora in AVI/Whatever and it's decompressed by ffdshow

geh, i discovered that, when hacking around Gabest OGM splitter for theora support (which was not that easy, and now, dropped ).

btw, now i've a stand-alone version of his splitter at least

? personnally, i won't make any OGM files anymore (there's better alternative and it's unsupported by Xiph -look to the ogg theora bitstream-). But now i can give a working filter to people when they complain about non-playing-OGM

RealPlayer can play Vorbis & Theora! Install this plug-ins for RealPlayer:
https://helixcommunity.org/project/s...php?group_id=7
Seeking doesnエt work (loses sync), but otherwise everything is fine.

yep. I was able to measure a whopping 1.6 dB PSNR improvement over a clip I made with an older ffdshow version (dunno if it was alpha 1 or 2). Too bad Theora playback with the latest ffdshow using DirectShow doesn't work for me anymore (crash in libmplayer.dll)... playing it with VfW (Vdub or AviSource()) works though.

Still, VP6 is almost 3 dB above Theora... let's hope Xiph can improve this codec a little bit more

cheers

I write a batch to automate the process
You need mplayer, ffmpeg and theora encoder in order to use this batch

Code:
mplayer.exe %1 -vc dummy -vo null -ao pcm
ffmpeg -i %1 -f yuv4mpegpipe - | encoderwin.exe -a 5 -V 1000 -o %2 audiodump.wav -
del audiodump.wav

Seek bugs fixed in RealPlayer 10 plugins
I've fixed the loss of lip-sync problems with the RealPlayer 10 Vorbis and Theora plugins. The new version is posted on the Helix site. If you have any other problems with these plugins, please post a message to dev@xiph.helixcommunity.org. I'll try to fix them as quickly as I can.
