similar to: Theora and WeBM support in Firefox and Opera

Firefox: 3.6 is out. What's new? I don't know (see :-( below) Trying to play videos: + Can play (in some cases) Internet videos + Can play (in some cases) videos from local storage + Seems to pass the testsuite tests , http://wiki.xiph.org/TheoraTestsuite , ("offset" looks good, 4:4:4 and 4:2:2 too, not sure about the 322x242 "not divisible by 16" - there is a black

Hi all, Sorry for the VP8 question on the Theora list, but I think all the relevant people are here :) I'm using Icecast to distribute some Ogg Theora streams at the moment with a view to adding VP8 along side these in future. Ideally I'd just use Ogg VP8+Vorbis, I know there is a mapping for this already but how much support from the browsers can I expect for this configuration?

Hello, I have proposed to WebM to use FLAC in a future version. Since 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. Here's the WebM discussion:

Hello, I?m new to icecast, after installing and configuring audio, I want to stream some webm videos in web browsers, so I have a few questions (I can?t find the answers in the docs) : - Which source client should I use ? - I want to stream an already encoded video, does it require a source client ? - How can I embed that in a browser ? Thanks by advance for your help. Olivier BATARD

Hey everyone. If you haven't seen this already, last week was Google I/O the third edition. The event page is : http://code.google.com/events/io/2010/ The youtube channel with the keynotes is : http://www.youtube.com/googledevelopers One of the most interesting things at that conference was the introduction of the WebM codec, which is a combination of On2's VP8 video codec (which is now

Hello , We are using Icecast for few years in a small french radio station with great success ! ( hitting 60 simultaneous listeners sometimes :-) ) http://www.radiogalere.org:8080/ Now we plan to stream the webcam capture of the studio, we 've done a test with Ogv/theora @128kb video with great sucess although none of the HTML5 browser wher able to keep on playing the stream after few

Hi! Short version of my question: How to produce Opus frames which can be safely concatenated and how to embed them into a WebM file? Long version: I'm currently implementing a web-based audio player which streams audio as opus/WebM using the HTML5 media source extensions. Currently, the server decodes a set of input files to a fixed RAW audio format (stereo, 48000 kHz) and encodes the

Hi Jean-Mark, thank you for your answer! Yes, you understood my question correctly. I was just about to compose a reply to my original question, where I described how I solved my problem. As you've already suggested, I've switched to Ogg/Opus, which is better supported, but does not work with the Media Source Extensions. I'll have a look whether disabling prediction will help with

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

Hi ! 2011/1/31 Romain Beauxis <toots at rastageeks.org>: > Well the interesting question is: "Is webm streamable?". Well it seems to ma that Google made Webm especially for streaming and I've even read that it should be easier to stream webm than ogg for various reasons. > Alternatively, there seems to be a ogg mapping for vp8 floating around: >

Hi Marvin I followed this advice for updating moov flags in mp4 and it "streams" directly from the file location on the server with html5 video: https://rigor.com/blog/optimizing-mp4-video-for-fast-streaming. Progressive downloading, seeking and video time all works 100% on a 195MB file. Regards On Wed, May 1, 2019 at 10:19 PM Marvin Scholz <epirat07 at gmail.com> wrote: >

Hi all, I finally understand how lipopusenc is capable of producing chainable Opus files (in contrast to my program), and I managed to successfully implement the method [1]. Essentially, the last frame of a file is marked as a "keyframe" by disabling prediction for this frame in libopus. This encoded keyframe frame is then copied in verbatim to the next file, with the pre-skip set to

What got me experimenting with Opus is that I heard it's going to be a supported codec in WebM, which I also have a Premiere plug-in for: http://github.com/fnordware/AdobeWebM I just posted a new beta that includes Opus support. Naturally, I *think* I'm doing it right, but I'd love for someone more knowledgeable about Opus or WebM to take a look. The closest thing to a standards

Hi Vorbis-Dev, I'm investigating various WebM/Vorbis bugs in chromium. AFAIK muxing Vorbis inside of WebM does not have an official specification, so I'm using ffmpeg's implementation to try to answer 2 questions: 1. Under what circumstances is it valid to find WebM Blocks containing Vorbis data with zero duration? (This would mean the next Block in the Cluster has the exact
