Hello there, I have been working on an alternative version of the png2theora example: The basic idea is to change the input of the program, using a QImage [1] variable instead of a png array. This is my base file: http://www.maefloresta.com/tmp/example.cpp The point where I am stuck starts at this comment: // LOOK HERE (line 313) And here is the issue: QImage supports RG...

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 reason it doesn&...

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 problem is in the setup of the encoder: keyframe_frequenc...

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. Manuel Dahmen. -------------- next part -------------- An HTML attachment was scrubbed...

...notable is that the encoder's rate control is much more configurable, and more capable in each configuration than before. It now supports two-pass, dynamic target adjustment, frame dropping, and other oft-requested features. For now the only documentation of the two-pass support is in examples/png2theora.c and examples/encoder_example.c. We'd particularly like to hear from framework and application integrators about how well the API design works. Source releases are available from the usual location: * http://downloads.xiph.org/releases/theora/libtheora-1.1beta1.tar.gz * http://downloads.xiph...

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. The basic program flow is: - start -...

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

Hi , I see in the libtheora 1.0 beta3 changelog that included new libtheoradec and libtheoraenc libraries supporting the new API from theora-exp , that it means that have multithread encoder? _________________________________________________________________ Express yourself instantly with MSN Messenger!

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. http://media.xiph.org/ED/ 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 of PNG files to raw YUV and to

Hi. I am trying to find calls of idct/fdct.c functions by tracing png2theora.c calls. But found only: analyze.c:oc_dct_cost2() Where and when idct/fdct/mmxidct/mmxfdct.c functions are used?

...les in lib/arm/ARMstate.c - fixup of include path in lib/arm/*.s - more relaxed configure.ac check to match debian on qemu vm - some compile fixes for a change in struct that became an array, it was called v iirc This is an RFC because there are two open issues: - plain ./configure fails because png2theora fails to link with libtheora, i have no idea on how to fix the issue. So my tests has been done with ./configure --disable-encoder --disable-examples --disable-float - something in the fast path for decoder is broken, in fact these fast paths are disabled in lib/decode.c via an undef.

Hi J., We are using ffmpeg2theora to produce an introduction video from a series of images: ffmpeg2theora-0.26.linux32.bin images/img-%03d.png -o intro.ogv The video that we get is huge and horrible, with lots of blinking colors: http://free-electrons.com/issues/ffmpeg2theora-mar5-2010/intro.ogv Here's what we had in the past:

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.

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:
