One thing I have noticed when encoding VCDs is that often videos with complex backgrounds don't compress nearly as well as those with simple ones. Part of the problem is that TV cameras seam to have the focus so that the entire image is clear rather than focusing on the foreground (and blurring the backgrounds). The result is that a good number of bits are wasted trying to perfectly

...stuck rendering mp4 in ffmpeg with our overlay, then ffmpeg2theoraing that mp4. This is problematic because we're also hoping to offer a live feed. Any advice or suggestions would be very appreciated. Peace A *the footage is currently available digitally in DRM'd & proprietary RealVideo; we think it's a better idea to have it available in an open format.

fast enough, and data transfer costs for video servers are low enough, and video codecs such as RealVideo 10 and VP6 are good enough that online video is practical today. For people who already have DSL, cable modem, or other broadband Internet connections, the biggest barrier to their being able to view any movie Hollywood has ever produced simply by pointing and clicking at some link on the Internet...

Hi: I know this is off-topic, but figured someone here would know, particularly given Xiph's involvement in Helix. Up till now I've used TRplayer <http://linux-speakup.org/trplayer.html> to play Realmedia content. This is because, as a Blind person, I've no need or desire for X11, and TRplayer uses the Realplayer libs without all that X overhead. but now I would like to play

I'm playing the "Honey" movie (both Honey-small and Honey-large) and I notice significant slowdown during periods of lots of motion (when the camera shakes, when the first man hops into bed, when people turn around and approach the camera, etc.). The audio plays smoothly all the time but when there is a lot of motion, the picture freezes and resumes when there's less motion.

...nificant quality improvements. Near CD-quality audio is now available at 48Kbps, beating Microsoft’s previous 64Kbps rate. For video, “near VHS” is available at 250Kbps, while “near DVD” is at 500Kbps. The quest for higher quality audio and video is growing rapidly. In May, RealNetworks announced RealVideo 8, which it claims can show VHS quality video at about 300Kbps. More recently, it announced RealAudio 8, which provides CD quality audio at 64Kbps – half the size of MP3. However, Microsoft now has the upper hand, with its announcement that it will support CD quality audio at 48Kbps. Windows Media...

Hello. Does the latest Linux real player support RealAudio 10? The RealVideo codec is available as a upgrade but does it include RealAudio10. As far as I know TRPlayer uses the installed Real libraries so it should work if RealPlayer supports it. Also would you mind sending me your compile of TRPlayer? I had some problems compiling it under Redhat 9. All the best Hash -...

Hi, I guess this is a good time to start putting together a wish list for a video codec. I see that for audio the compression is around 10X for reasonable quality. I am sure this will start its own thread of conversation. For video you can do 40X fairly easily and the big task is to go to 80X or 100X with reasonable picture quality, say, a peak luma SNR of more than 30 dB. Uncompressed

Hi List, Just batting a few ideas around here, but would it be possible to include in to the codec, estimation for common video artifacts that occur in the analogue world? For example, anything that's gone through a composite stage will likely have dot-crawl and false colour - if we can recognise this effect in the encoder, we can treat it as a special case. Other artifacts that come to
