Hello everybody, I hope to finish this MIME types discussion with these conclusions - it's taken enough bandwidth on these lists :). So here's a generic MIME types scheme that we all seem to be able to agree on and all that is needed for the moment. --- 1) Ogg encapsulated files: Any data that is encapsulated in an Ogg container will us the MIME type: application/ogg (as already

As I understand it the current plan is to make it possible to losslessly transcode VP3 video to Theora video. In my experience, one of the "features" of VP3 is it drops frames in the event that there is little/no movement in a frame, or if "drop frames" is enabled, to drop frames if the data rate is getting too high. I understand that the way that VP3 does this in

This comes from Indymedia audio list, Whamb! should probobally be listed on the vorbis.com software pages. ----- Forwarded message from nathaniel t <vsea75@hotmail.com> ----- The whole world doesn't use Linux or Windows.

I don't know how to change a video quality on the fly - I want to provide a slider with a preview window, so user could see the result immediately in this window. I tried to send ICM_COMPRESS_FRAMES_INFO to encoder or calling ICSetState() - with no success however. Am I doing something wrong ? How can I set 'lDataRate', 'dwRate', 'dwScale' parameters ? I tried every

I found out about vp3 from the new winamp and coincidentally i also happen to be trying to find a suitable solution to broadband streaming. I have used flaskmpeg to create a 17mb .avi file from an 82mb Mpeg 1 file and it looks great it took about twenty minutes to encode. It runs for eight minutes and the audio is also fantastic using the lame encoder. However when I try to do the same in

We will need some optimization because now this codec is way too slow for home uses. --- end of quote --- Actually, the Windows VP3 QuickTime codec runs just fine on a 400MHz Pentium II box, with only occasional glitches on some dodgy Celeron systems. At work, we routinely test 320x240 full-color, full-motion video on low-end boxes.

I haven't actually had many questions up to now. Despite the all-encompassing CP_INSTANCE monolith, things have been relatively easy going. Now we get into real grit: First off, CBitman looks like it has endianness issues; it's packing into host-order 32 bit arrays (the comments and symbol names seem to indicate that this was originally byte-based packing code that got upped to 32 bit.

some of you may find this helpful: I've uploaded a short (5 second) raw clip in yuv4mpeg format, associated audio, and batch files to exercise the encoder & decoder examples. In addition I've included the file as compressed (test.ogg), and a longer version as well to test playback sync. Notes: to use MPlayer with the -vo yuv4mpeg option, you need to get the latest release and compile

Hi, So it took a little while to get here but VP3 through ffmpeg is finally starting to achieve viewable results. It partially works right now. Keyframes only. And monochrome. Oh, and the picture is upside down (something I did not realize about VP3 until I let it fly just now). Anyway, here is a picture of ffmpeg's VP3 decoder in action using xine:

Hi, Is there anything special I need to know about VP3's IDCT? I mean besides the fact that there are separate IDCTs to handle sparse coefficient matrices. Are the IDCT functions mathematically equivalent to any textbook IDCT functions?

Hi, I am making good progress on understanding, documenting, and re-implementing VP3. I have found some more deadwood in the decoder code and I just wanted to verify that it really has no place: * Version 3.3 tables: There are 2 sets of VLCs: One for v3.1 and one for v3.3. The v3.1 set is always selected. Are the v3.3 tables in production, or will they ever be? * DC Search Points: VP3

Hi Guys, I have been using the VP3 codec for the last few months to encode a single feed from a video camera. I now need to compress multiple camera feeds simultaneously using the VP3 codec (for Windows). Does anyone know if the codec would support multiple feed compression (i.e. get the inter/intra frame compression per feed right), or if I would need to make some changes? Regards Oliver ---

Hi DVD-Quality playback uses 100% CPU on my Athlon 1333 MHz. My Duron 800 can't play them. XviD uses ~25%. Does someone have few tricks for that?

This comes from the Indymedia global audio list. How about setting up a software page on icecast.org with a list of players that work properly? Many players on vorbis.com will only play files on a hard drive, not streaming files, such a list would be very helpful towards promoting Ogg as a useful streaming format. ----- Forwarded message from nathaniel t <vsea75@hotmail.com> ----- The

Is theora based on Floating Point or Integer. I haven't looked at it much, but would like to help make sure it runs on other architectures ok. (especially: StrongARM (Zaurus) and DEC Alphas) Also as of now how efficient is the player compared to mpeg4? Aside from constant rewrite (as theora changes), why would someone not want to write a plugin to test it? Just new to theora, and

Well, I've been slamming my head against this all night, so it's time to ask for help... Having gotten together a reasonably decent port of what I thought was the whole API to the Ogg Way, complete with Ogg mem management and bitpacking, I started digging deeper in the code... only to find that it looks like I only have a middle stream handler. The encode and decode code both assume that
