+ - Mozilla Encoder improves JPEG-compression

Submitted by jlp2097
jlp2097 (223651) writes "As reported by Heise (german), Mozilla has introduced a new jpeg encoder called mozjpeg. Mozjpeg promises to be a "production-quality JPEG encoder that improves compression while maintaining compatibility with the vast majority of deployed decoders". The Mozilla Research blog states that Mozjpeg is based on libjpeg-turbo with functionality added from jpgcrush. They claim an average of 2-6% of additional compression for files encoded with libjpeg and 10% additional compression for a sample of 1500 jpegs from wikipedia — while maintaining the same image quality."

+ - Why IE9 will not support other codecs than H2.64-> 2

Submitted by jlp2097
jlp2097 (223651) writes "There is a new article up on Microsofts IEBlog explaining why IE9 will only support H.264:

First and most important, we think it is the best available video codec today for HTML5 for our customers. Relative to alternatives, H.264 maintains strong hardware support in PCs and mobile devices as well as a breadth of implementation in consumer electronics devices around the world, excellent video quality, scale of existing usage, availability of tools and content authoring systems, and overall industry momentum – each an important factor that contributes to our point of view. H.264 also provides the best certainty and clarity with respect to legal rights from the many companies that have patents in this area.

The article goes into detail for each of these points and is an interesting read, confirming a lot of points already discussed here."
