Updated version of video preview covering frame writing every 3 keyframe and a xsl typo. Best regards :) kysucix -- Make things as simple as possible, but no simpler. - Albert Einstein

Hi. Here it is my patch to put a video preview of a theora stream in status.xsl. I just added a: <video-preview>1</video-preview> parameters in icecast.xml.in that control the previewing function. It encodes a png in $webroot/$mountname.tmp and then move it to $webroot/$mountname.png As for now it saves a frame every theora keyframe, which is probably too heavy for the server but

Hi, I''m using prototype/Scriptaculous in my open source project JSControlsTags http://jscontrolstags.sourceforge.net/ I''m Struts user and in the new version Struts2, the framework integrate AJAX with dojo and not with Prototype/Scriptaculous. I asked in the Struts forum, why Struts2 integrate by default dojo and not scriptaculous. Here Struts answer : ------------------------

I found a bug in theora_decode_init when I was implementing the decoder. theora_decode_init should be zeroing the theora state structure right? memset(th, 0, sizeof(theora_state)); // Erik -------------- next part -------------- An HTML attachment was scrubbed...

hi folks! i would like to know whether there will be some function to decode to some plain 24 bit RGB buffer in the future. i think this feature is sometimes important, especially when using different surface layers, or when modifying the buffer in realtime. if this feature will definitely not be, could someone tell me how i can convert to some RGB buffer in realtime? i already tried different

Hello, I want to make a program to extract frame from a theora movie as images. I tried with the decoding example located at theora web site (dump_video.c. I use it to extract a frame as yuv image but when I try to convert it to ppm with yuvtoppm program i obtain a strange image ( see http://poux.be/tmp/file.ppm ). I think it's a problem with the byte order for yuv, but don't I don't

I'm currently doing research and initial development for an app that requires a rather odd usage of some kind of movie decoding. I'm trying to find a codec that I can trick into doing what I want, and so long as I can fix a problem or two, Theora is looking promising. What I want to do goes something like this: 1) Encode a whole bunch of two frame movies. For each movie, the

Hi, I have been working with VP3 for some time now. Dan Miller from On2 just told me about this list. A few months ago, I managed to get On2's VP3 source snapshot to compile under Linux, a feat that many have apparently attempted and quickly abandoned. I compiled a small console app and the results of the experiment are explained here:

I posted a while back "complaining" about lack of a theora player on the iPhone. Porting the code for libtheora (and libogg/libvorbis) was (relatively) painless, and appears to be working. I'm up against a tougher challenge now... rendering the video! I tried using the brand-new SOC-funded SDL port to iphone to get the "player_example.c" code up and running, but ran into

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

Hello all, When I'm doing something like: yuv_buffer yuv; theora_decode_YUVout(&td,&yuv); I'm guessing a bunch of stuff gets newed/malloced for yuv.y, yuv.u, and yuv.u. Who is responsible for deleting/freeing that stuff? Cheers, Kos.

I've spent the weekend or so trying to get my head around Theora and I'm just not having any luck. First of all, I really don't have any interest in immersing myself in video encoding--I just have one simple thing I'd like to do--so I haven't spent any time reading about the theory or specs or anything like that. I'm attempting to write a "render-to-theora"

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.

Hi all, I'm trying to get rsync running on a Windows 2k box (my tape backup server) to remotely back up stuff from a few unix boxes. Not my favored constellation, but there's not much I can do about that. I'm hoping someone could give me a quick tip or two on getting rsync working as a Win2k service. I'm not real proficient with Win2k, so be gentle. The posts I could find

hi all I guess that *Theora* will convert the input color space (RGB or CMYK or any) into YUV before it process and encode. (that means theora can operate on several color space, but it get convert into YUV before process) Is that true...? I want to get a gray scale, encoded video output from the *Theora* encoder while the input video is getting from a web cam (color input and gray scale

Double negative, so I take your statement to mean that there *is* such

Enabling the following function in tests/noop.c: noop_test_decode () { theora_info ti; theora_state th; theora_info_init (&ti); theora_decode_init (&th, &ti); theora_clear (&th); theora_info_clear (&ti); } segfaults. The cause is that theora_decode_init() expects a theora_info structure which was previously initialized by passing actual bitstream data through

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. -- Nuwan Millawitiya -------------- next part -------------- An HTML attachment was scrubbed... URL:
