OpenCodecs release 0.84.17338 ----------------------------- OpenCodecs is a set of DirectShow filters for playing Ogg Vorbis, Speex, Theora, FLAC, and WebM files in Windows Media Player and other players. This release added WebM support (using versioned snapshots provided by The WebM Project), which determined the change of project's name from "Ogg Codecs" to "Open

...e. As an example of how MCA can be used to improve scheduling, we have built a prototype machine scheduler that optimizes the simulated latency of a block of code under the constraints of the scheduling DAG. We've had interesting wins of 2-3% on assembly kernels for webp <https://github.com/webmproject/libwebp/commit/67748b41dbb21a43e88f2b6ddf6117f4338873a3> and gemmlowp <https://github.com/google/gemmlowp/pull/91>*. The patch is completely mechanical and can be seen here <https://reviews.llvm.org/D55557>. It only moves the files and updates all references. We'd like to hear...

Google has opened up VP8, and has lined up about 40 companies/organizations (including xiph) in a coordinated launch: http://www.webmproject.org/ Anyone know where there are quality comparisons between H.264, Theora, and VP8? -SteveK

I did some tests: ### Theora support in Firefox 3.7a (missnamed as "Minefield"): Same as since 3.5 (plays, no controls if Javascript off, no thorough retest of buffering issues). http://lists.xiph.org/pipermail/theora/2010-January/003369.html http://bugzilla.mozilla.org/show_bug.cgi?id=449358 ### WeBM support in Firefox 3.7a Seems to play (controls bug of course also there) and

I think that should be interesting if we could upload videos of the applications that we test on wine to the AppDB and Bugzilla. I recently tested the WebM encoder (http://www.webmproject.org/) from Google and it seems to produce videos with a great quality and small file sizes. The most recent versions of Chrome and Firefox are able to play this format nativily. This would help people share their problems and findings more properly. It would be very nice if we could put these video...

Hello, I would like to know if there is a plugin for internet explorer 9 so that it supports playback of Ogg Vorbis files. In fact, I'm devellop a media site, and I use the tag <audio>. Since I want to promote ogg vorbis, I will require users to post their music in this format. For versions of Internet Explorer less than 9, I'll use a flash drive that can play ogg files. His name

...FLAC was designed a decade ago, I was wondering if there were any new compression techniques that FLAC could use in a new version to improve compression ratios. If so, it would be worth synchronising with WebM for compatibility reasons.

...lication is for (automated) optimization. We’ve experimented with using predicted throughput to schedule instructions. This has resulted in significant wins (see e.g. this PR improving a gemm kernel <https://github.com/google/gemmlowp/pull/91> and this PR improving WebM <https://github.com/webmproject/libwebp/commit/67748b41dbb21a43e88f2b6ddf6117f4338873a3>). We think it could also be used to improve instruction selection to offload some ports (typically un-vectorize some computations on Intel CPUs, where port5 typically becomes saturated for vector-intensive computations).To enable this, it...

Hi all, At Sony we developed an LLVM based performance analysis tool named llvm-mca. We currently use it internally to statically measure the performance of code, and to help triage potential problems with target scheduling models. We decided to post this RFC because we are interested in the feedback from the community, and we also believe that other people might be interested in a tool like
