Last night I went to the Denver IEEE meeting of the Signal Processing Society. I was particularly interested in this talk because it was given by Gary Sullivan, the co-chair of the recent international standardization effort to create the High Efficiency Video Coding Standard (HEVC).
This is a follow-up to my World?s Smallest h.264 Encoder post. I?ve received several emails asking about precise details of things in two entities in the h.264 bitstream: the Sequence Parameter Set (SPS) and the Picture Parameter Set (PPS). Both entities contain information that an h.264 decoder needs to decode the video data, for example…
Evidently the Justice Department is investigating MPEG LA on the grounds that they may be stifling innovation in the area of standards for web video.
I?ve been waiting a little to mull over Google?s announcement about dropping H.264 support in Chrome in favor of VP8. Although my partner Ben Mesander would take the other side of the argument, I think the world needs VP8 like a fish needs a bicycle.
My partner Ben Mesander had a really cool post the other day: An h.264 encoder written in 30 lines of C code. Ben?s encoder outputs completely valid h.264, but it doesn?t actually compress anything. (What do you expect from 30 lines!) In fact, because of the necessary h.264 headers, the output of Ben?s encoder is…
Recently I have been studying the h.264 video codec and reading the ISO spec. h.264 a much more sophisticated codec than MPEG-2, which means that a well-implemented h.264 encoder has more compression tools at its disposal than the equivalent MPEG-2 encoder. But all that sophistication comes at a price: h.264 also has a big, complicated…
I just spent the last three days at the IACP show in Denver—the annual conference and expo for the International Association of Chiefs of Police. For anyone who was once a 12-year-old boy, IACP is about as cool as it comes, because there is all sorts of cop paraphernalia on display—from Bell helicopters to Sig…
