VP8 for Real-time Video Applications
15 février 2011, par noreply@blogger.com (John Luther)With the growing interest in videoconferencing on the web platform, it’s a good time to explore the features of VP8 that make it an exceptionally good codec for real-time applications like videoconferencing.
VP8 Design History & Features
Real-time applications were a primary use case when VP8 was designed. The VP8 encoder has features specifically engineered to overcome the challenges inherent in compressing and transmitting real-time video data.
- Processor-adaptive encoding. 16 encoder complexity levels automatically (or manually) adjust encoder features such as motion search strategy, quantizer optimizations, and loop filtering strength.
- Encoder can be configured to use a target percentage of the host CPU.
Ability to measure the time taken to encode each frame and adjust encoder complexity dynamically to keep the encoding time per frame constant - Robust error recovery (packet retransmission, forward error correction, recovery frame/new keyframe requests)
- Temporal scalability (i.e., a single video bitstream that can degrade as needed depending on a participant’s available bandwidth)
- Highly efficient decoding performance on low-power devices. Conventional video technology has grown to a state of complexity where dedicated hardware chips are needed to make it work well. With VP8, software-based solutions have proven to meet customer needs without requiring specialized hardware.
For a more information about real-time video features in VP8, see the slide presentation by WebM Project engineer Paul Wilkins (PDF file).
Commercially Available Products
Millions of people around the world have been using VP7/8 for video chat for years. VP8 is deployed in some of today’s most popular consumer videoconferencing applications, including Skype (group video calling), Sightspeed, ooVoo and Logitech Vid. All of these vendors are active WebM project supporters. VP8’s predecessor, VP7, has been used in Skype video calling since 2005 and is supported in the new Skype app for iPhone. Other real-time VP8 implementations are coming soon, including ooVoo, and VP8 will play a leading role in Google’s plans for real-time applications on the web platform.
Real-time applications will be extremely important as the web platform matures. The WebM community has made significant improvements in VP8 for real-time use cases since our launch and will continue to do so in the future.

How to play video file with 720x480 and 60fps on ipad using ffmpeg
12 septembre 2011, par akashI can play video files with 320x180 resolution on ipad but files with more than 320x180 and 60fps are playing slowly. anybody can tell what will be the issue.?
is iOS supports playback of files with 60fps ?
