Hello,

We are new to Flumotion and streaming and are looking for anyone who has experience with it to help us set up the software and maintain it on a long term base. I see that there are guys here who may be able to help us.

You may contact me at willy(at)payservices.com

Thanks

Willy

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

[...] 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。 [...]

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