Quoi de mieux pour visiter le Kennedy Space Center et rêver d'espace que ce magnifique livre d'@EricLagadec.
Although I like the new colors in Google maps, I don't think the design is good for car navigation. I find it confusing that the contrast between my navigation path and the background is not high enough. Is there a way to change that?
Just updated the GitHub page github.com/MPEGGroup/FileFor… that lists all work items in the MPEG File Format group. New editions of major standards coming up: ISOBMFF 8th edition, NALU FF 7th edition, HEIF 3rd edition; and lots of new amendments too. Check them out!

AOMedia today announced the release of the Immersive Audio Model and Formats (IAMF) container specification, the organization's first-ever audio container specification to be offered under AOMedia’s royalty-free license. Read the full release here -> brnw.ch/21wEj8V
MP4 devs know it's hard to keep up with specs. Finding the syntax of a box is hard. @MPEGgroup just released mpeggroup.github.io/FileForm… . You can search for a box (or combination of) and get a snippet of the syntax and the list of corresponding conformance files (if any).
and if you search for the latest specs themselves, bookmark this page github.com/MPEGGroup/FileFor…

Calling in the Open Source community around AV1. I just created a GitHub issue github.com/AOMediaCodec/av1-… to track open source projects that could use some help to add or improve their AV1(-ISOBMFF) support. If you know of such project, please add them to the issue.
Thanks to @enginetankard you have no excuse to mis-signal priming samples in compressed audio. It's all explained here medium.com/vimeo-engineering…

Found 20-30 year old audio cassettes. Using Shazam to recognize these heavily distorted songs. Works like a charm. Impressive!
The File Format group of @MPEGgroup is collecting information on how decoder implementations (audio, video, ...) are initialized in practice. What information is needed. What is not necessary. Why. You can provide feedback in this GitHub issue github.com/MPEGGroup/FileFor….

The File Format group at @MPEGgroup is responsible for many standards, e.g. the Emmy-winning #ISOBMFF or #HEIF. It is sometime difficult for non-MPEG members to follow. Now, it should be easier. A public page github.com/MPEGGroup/FileFor… tracks what's happening. Hope it helps!
For those interested in details around the high-level syntax of the #opus audio codec, you can now inspect Opus files with @wearegpac: either "MP4Box -dxml opus.mp4" for MP4 files or "gpac -i file.opus inspect:deep:analyze=on" for Opus files, Ogg files, or else. #Opensource
