WebM and VP8 streaming live from Flumotion
We did it! Today we managed to get Flumotion to stream live over http a test signal encoded in Vp8 and muxed in the WebM container.
The below screenshot shows Firefox webm developer preview playing it back in browser!
It requires patches to GStreamer and to Flumotion. So what you need is:
- libvpx from webmproject
- git master of gstreamer, gst-plugins-base, gst-plugins-bad
- git
of gst-plugins-good from my github repositorymaster of gst-plugins-good git of Flumotion from my github repositorysvn trunk of Flumotion from https://code.fluendo.com/flumotion/trac/wiki/Documentation/DeveloperIntroduction#getting-your-development-environment-installed
Thanks to Google for opening up vp8 and throwing the HTML5 video tag’s codec race wide open! Thanks to Collabora (especially Sebastian Dröge) and Entropy Wave (especially David Schleef) for getting the GStreamer plugins in shape! Thanks to Mark Nauwelaerts for fixing bits in the matroska muxer so it doesn’t output small buffers then seek every ebml tag! Thanks to Andoni Morales and Xavier Queralt for also putting in a lot of time after hours to work together to have the streaming working quick-smart.
I believe we are the first free software live streaming solution to have VP8 in WebM streaming live to browsers, if we are not we are definitely one of the first. This makes me very proud. We still have work to do to clean up the patches we have done and push them upstream to GStreamer and to Flumotion. There is still some work to do in cleaning up the patches and get them upstream in GStreamer and Flumotion but the hard part is done.
UPDATE: All the patches have landed into GStreamer and Flumotion so no need to use my repositories any more, just get from upstream! Also we have an official demo up at http://www.flumotion.com/demosite/webm/

Awesomeness to the nth degree!

Brilliant!

Would it be possible to stream to an icecast2 with vp8???????
thanks.
May 21st, 2010 at 4:19 pm
walo, I don’t think icecast2 supports vp8 in ogg or vp8 in webm. Flumotion with the git rep mentioned in this blog post supports both.
May 21st, 2010 at 4:23 pm
Great job guys! It makes me proud to be a Flumotion employee.
May 21st, 2010 at 5:16 pm
Where’s the PR?
Just joking, good work!
May 21st, 2010 at 7:21 pm
ok, but, ¿can i install a flumotion server? or it isn’t free???? i want to stream in vp8 from a webcam client with flumotion-admin to a server, so ¿what do i have to do?
yo [at] alvarolara [dott] com is my email address please, contact me!!!
thanx

Woho, this is cool Zaheer.
Congrats
May 22nd, 2010 at 6:06 am
Awesome. I had no idea webm (or rather matroska) was streaming-friendly. And yay on Mark fixing the muxer !
Regarding the icecast question, if it can silently forward formats it doesn’t know about, one should be able to use a gstreamer pipeline (with latest -base) to create a ogg/vorbis/vp8 stream and push it out to icecast for streaming. Problem is that the ogg mapping for vp8 is still unofficial (read “only gstreamer-based players should be able to handle it”).
Carry on the good work
May 22nd, 2010 at 6:06 am
This is great. Are there any implications for adaptive bitrate streaming?
May 22nd, 2010 at 5:34 pm
That’s excellent (and very quick) work!
Thanks for this, I can’t wait to see all the code unleashed in stable releases.

while select webm flumotion shows error message:
Worker ‘localhost’ is missing GStreamer element ‘vp8enc’.
Please install the necessary GStreamer plug-ins that provide these elements and restart the worker.
devices are webcam and soundcard, and the ogg works.
all the package are installed with some thing like the following:
autogen.sh –prefix=/usr
make install
how to setup GStreamer with support for element ‘vp8enc’?
May 24th, 2010 at 1:03 pm
all packages are from the git provided in ths page
May 24th, 2010 at 1:04 pm
so I guess I might have missed some configure args concerning webm/vp8
May 24th, 2010 at 1:04 pm
pdfan, do you have /usr/lib/libvpx.so on your system?
May 24th, 2010 at 1:43 pm
yes, libvpx is installed, and ffmpeg installed with google webm patch, and it can save stream to webm file, but the live feed not work.
your demo just plays several seconds in my webm firefox and then stalled foreve.
May 24th, 2010 at 7:51 pm
I need support webm on my Apache, how to make this?
May 24th, 2010 at 7:54 pm
@pdfan: Do you have the vp8 encoder gstreamer plugin installed too?
The libvpx build system is horrible and ‘make install’ doesn’t install the headers in the right place and most likely it hasn’t been selected to be built because the headers were not found by the gstreamer’s ./configure script
Chek that when you run ./configure for gst-plugins-bad, this plugin is marked to be compiled.
For instance we needed to copy manually the libvpx headers to /usr/local/include/libvpx.

@pdfan: the ‘is-live’ property is part of the patches added by zaheer and xqueralt to the matroska muxer. If this property is missing that’s because you are not using zhaeer’s gst-plugins-good branch from github

May 26th, 2010 at 6:34 am
pdfan, you need the webmlive branch from my github.
Also we were the first to do LIVE streaming of webm, Cherokee just does serving of files at a speed just above the bitrate of the file but still files.
May 26th, 2010 at 6:36 am
maybe I missed a patch that set the is-live property for webm?

@pdfan looks like an issue with the webcam producer, please come on #fluendo on irc.freenode.net in irc and ask there, we can give interactive help hopefully.

@solca: what Cherokee did is not live streaming, but streaming a static file through progressive download, which is very different.

[...] 我们的发布在社区中引发了关于设计以及开发版质量的讨论。我们针对 VP8 进行了大量测试，结果该编码完全可以胜任或超越其他领先编码的质量。从本周起，WebM 幕后的工程师们将在本博客定期发表关于如何使该方案中的 VP8 视频编码与 Vorbis 音频编码取得最优化的利用。我们相信开放的开发模式将带来额外的改进，这些改进将进一步优化 WebM。事实上，开放开发的力量已经显现，开发者提交 patch，Flumotion 在项目启动仅三天内就在他们的产品中实现了 直播流支持。 [...]

Hi all:
These days i’ve been understandig how flumotion works, and now, i’ve got flumotion configure and working, with ogg theora, now i want to stream with vp8.
I’ve installed 0.62 version of flumotion, all the gstreamers, the libvpx, but nothing else matters, in flumotion’s assistant, it doesn’t appear the webm/vp8 codec, but if i type in a shell gst-inspect | grep vp8, it appears:
vp8: vp8dec: On2 VP8 Decoder
vp8: vp8enc: On2 VP8 Encoder
so i think the codec is installed.
How can i configure flumotion in order to have webm/vp8 streaming???
THanks
