png2theora example
Hey everyone;
I've been pulling my hair out trying to figure out what I'm doing wrong with
the png2theora example found in the libtheora-1.1.1.
When ever I encode a set of .PNGs, everything seems to go well, but I'm
getting inconsistent results when viewing in various players.
Firefox, with it's built in .OGV player, plays the video just fine.
VLC plays the .OGV, but for some

Live Stream Encoding
Hi There,
i want to stream some pictures out of my application using the Theora
codec. I can stream to a socket or a file. The current work based on the
png2theora example. Something while enconding went wrong: I can see the
whole video in VLC, but the complete duration of the file will not be
displayed. If i play the video in Firefox, the first 2 seconds will not
be played. I think the

limitation in encoder
HI,
I have a question about libtheora examples. I have modified png2theora source code and the encoder stops after 3000 encoded frames. I don't know if it s a limitation in libtheora or something else.

Creating a Streaming Server
Hi,
Is there any sample code out there that might give me a sort of "bare
bones" example of how to create an Ogg streaming server that would
produce a video/audio stream suitable for consumption by the HTML5
VIDEO element? The video being streamed will be generated dynamically
using libGL. I have the pixel data for each frame of the libGL
rendered image available to me, so really I am

After months of intensive development, we're finally coming to a
stopping point in our rewrite of the libtheora reference

bug fixing now. Please try this first beta and give us feedback. Most
notable is that the encoder's rate control is much more configurable,

Elephant Dreams test video
I recently found these sample videos for codec/decode testing and was
wondering if someone can give me more info on these files and how to
use them.

First I would like to know what is the frame rate needed for the
ED-360 and ED-1080 to be sync with the audio samples??
Second what tool (specific command) can I use to convert this sequence

ffmpeg2theora bug: generation of a video from a series of images
Hi J.,
We are using ffmpeg2theora to produce an introduction video from a

encoding raw file (.yuv) using ffmpeg2theora
Hello!
I'm trying to use ffmpeg2theora to encode raw (.yuv) files in I420
format (just frames, no headers at all), but failed to find
corresponding input format. Is there any documentation of supported
formats for ffmpeg2theora?
Or maybe there is another command-line tool for Windows to encode raw
video using Theora algorithm?
Thank you for help!
Alexander.

Page breaks when encoding ogg/theora
Hi everyone,
I'm trying to build theora encoding into my game engine. Essentially,
I'd like to do something similar to png2theora.c, where I take
individual screen shots of my game and encode them into a video.
Because png2theora.c uses the legacy C API, I used encoder_example.c
as a template instead. encoder_example.c seems to be the only code out
there that actually uses the th_* API.

Ogv file only plays in VLC / Can't be used by most tools.
Hi,
I'm new here - thanks for having me. (Sorry if I'm in the wrong place or a noob.)
I downloaded the Theora encoder sample (ver 1.1.1), modified it to encode a sequence of bitmaps, and created an OGV file.
The OGV file plays fine in the latest VLC (1.0.5), but I can't do much else with it:
I tried uploading to YouTube, and the video just comes out really corrupt:

idct/fdct.c function calls
Hi.
I am trying to find calls of idct/fdct.c functions by tracing png2theora.c calls.
But found only:

Where and when idct/fdct/mmxidct/mmxfdct.c functions are used?
Mentions of "dct" word:
