can not encode a raw video file with "encoder_example"
hi all,
i tried to encode a .yuv file with the encoder_example.c
but it give an error message as follows
./encoder_example -v 1 file_1.yuv > file_1.ogg
Input file file_1.yuv is neither a WAV nor YUV4MPEG2 file.
so the error message is understandable for anyone.
when this file is play with mplayer it shows as follow

Using Theora Micro-HOWTO
Okay, thanks to some stubbornness on my part and helpfulness on the part
of people on this mailing list, I got the Ogg Theora alpha compiled up
and installed and running.
Yesterday, I went to the Prelinger archives (the public-domain video
archive at www.archive.com) to find a high-quality original to re-encode
as a test. The encoder worked just fine, and playback as well, and I thought
I'd

Encoding from fifo's
Hello, I'm new to the list, so if this is an FAQ, please point me to the
relevant docs.
I'm playing with Theora, to see what kind of quality I can expect (I
realise its not for production use yet). I've download the source from
CVS, and got it to build, with the example encoder and player.
While trying to find something to serve as a good source of input, I
decided I'd use a

trying to encode from dvd using mplayer
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 -vo yuv4mpeg -ao null -nosound /dev/dvd &

Testing libtheora-1.0alpha5
Hi,
I sent the message below a couple of months ago but I got
no reply. Now that there's more activity perhaps someone
could kindly provide me some guidance. Theora is great
and the developers are doing a wonderful job, so I'd like to
implement the codec in a way which does it justice...
Original post:
I wrote a plugin to enable LiVES (a video editor) to encode
theora/vorbis/ogg files.

Sampling encoder timings between libtheora-1.0 & libtheora-1.1beta3
As requested by Ralph in my introduction e-mail to this list [1], I've
gone ahead and done some sample test timings for encoding between
libtheora-1.0 and libtheora-1.1beta3, as available from the Theora
website [2].
So far, I've tested with 4 different files that I generated with content
I already have. The files, in brief, are the following:

Theora file size
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

I'm a highschool student,
I'm looking for information about converting Wave file

it using Microsoft Visual C++ 6.0 ,but it goes error

Encoding with encoder_example
I have encoded successfully a YUV stream by using the encoder_example. Can
We encode a row stream (get from a web cam) by using encoder_example.
If we can not, is there any other way to encode a row stream by using theora
codec.

encoder_example input formats
Hi all
I have the raw out put of a video camera in following
format: mjpegb, yuvj422p, 1920x1080, 24.00 fps(r).
I cannot directly convert this raw footage to Theora
due to the YUV4MPEG2 only restriction of the
encoder_example.
Isn't it better to support other raw formats in
encoder_example, such as what I have, mjpegb,
yuvj422p?
I presume even if I convert the mjpegb, yuvj422p to

Audio from fifo
My first guess about the problem would be that the programs want
to process the stuff in a different order, e.g. mplayer wants to
output some sound before anymore video and encoder_example wants
to receive some video before anymore sound. This could easily
depend on the order of stuff in the file mplayer is reading.
I guess something similar could happen for opening the pipes as
well.

New addition to FAQ
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.

Bug(?) in the example encoder (details re: audio from fifo)
I did a little poking about with the pcm-from-fifo problem I
was having...
What I'm attempting to do is an on-the-fly export from one file
using mplayer to generate yuv4mpeg video frames and pcm audio, piped
through fifo's. This DOES work with mpeg2enc/mp2enc, so I'm assuming
it's not a problem with, e.g., my filesystem...

A/V sync strategies
I tried to encode some video from a DVD with encoder_example and
ffmpeg2theora, and it looked great, except that with both encoders the
A/V sync would drift noticeably after about 10 minutes, and by the end
of a two hour movie it would be a couple seconds off. So instead of just
whining about this and waiting for someone else to fix it, I decided to
try to learn about what's causing the

error in "encoder_example.c"
Hi,
Why do I get an error message when i'm running the
"encoder_example.c" which is included in the SDK?
The error occurs then the 44 bits are read and the
vorbis_info struct is initiated (i.e. when the
vorbis_encode_init(&vi,2,44100, -1, 128000, -1) -
funcion is called. I also tried to read the data from
a 16 bits 44,1 KHz stereo PCM - wave file but recived
the same error.
