This can be discussed in gstreamer embedded. Thanks ________________________________ From: gst...@li... [mailto:gst...@li...] On Behalf Of Alex Rades Sent: Friday, March 28, 2008 5:56 AM To: gst...@li... Subject: [gst-devel] gstreamer & dsp Hi, I'd like to set up a dedicated transcoding server at work. Is there any PCI/PCI-express DSP board *supported by gstreamer* for mpeg4 coding/decoding? I've read something about TI Davinci family but they seem to be no available as standalone pci/pci-express boards. Links to actual hardware to buy would be greatly apreciated. Thanks! |

There are OpenMAX IL hardware decoders/encoders and with gst-openmax it's possible to use them. I've been able to use OMAPx430 hardware capabilities that way. Also, the DaVinci stuff is publicly available: http://wiki.davincidsp.com/index.php?title=GStreamer Best regards. -- Felipe Contreras |

Hi, I've tried to look around for OpenMAX hardware decoders/encoders but i cannot find real world product, for example a pci/pci-express board to buy. Do you have suggestions?

There is no gstreamer interface to the outside of the chip. So if you find a board with this chip you still need to write the gstreamer interface for the host-machine yourself. Gr, Thijs |

Hello, Maybe the best option for a desktop-friendly product is the DaVinci PCI development board, but it's price may be "a bit too high" for production use. For fast cross-system prototyping, tcp gstreamer elements have always proved viable to me, but some real inter-processor communication protocol / memory access might be needed for achieving a real integration (DMA transfers ?) It may be interesting to start a wiki article with interesting hardware-en/de-coding devices, that may be suitable for destkop (non-embedded) gstreamer integration (mostly USB or PCI form factors). Where should this article be ? (http://gstreamer.freedesktop.org/wiki/HardwareAssisted ?) With wtay's help, i've been trying to decode an RTP h264 stream from the FastVDO SmartCapture [1] device, without success. Which means i'll probably have to integrate it into a proper gst src element so that the RTP payloading is done in Gstreamer (unfortunately, this kind of plugin is not publishable). I guess this is a common issue about hardware-assisted GStreamer elements: NDAs. For such dedicated products, how should NDAs be handled without letting all the dev work closed ? Maybe the best would be to have clean templates (usbsrc?) for such elements without the often NDAed parts. What are your thoughts about NDAs in such a context ? Regards, FLo [1] http://fastvdo.com/SmartCapture/ |

H Alex, I know some people have been using the Micronas MicRacer card with GStreamer, but I do not think there are any publicly available GStreamer plugins available yet.

So basically aren't there hardware mpeg4 decoders/encoders supported by gstreamer?

Hello, > So basically aren't there hardware mpeg4 decoders/encoders supported by > gstreamer? I'm desperately looking for x86-friendly hardware assisted gstreamer elements as well, especially if non embedded-specific (ex: usb form factor or pci), in the contrary to Ti's DSP products: AFAIK none of these products can really integrate as "simple" encoder elements into a destkop gstreamer ("get frames, return bitstream") but offer analog-to-encoded content features. For anyone wanting to do pure offscreen rendering, the analog conversion step is a bit quality-killing... I'd be glad to have more information about related topics as well... Kind regards, Florent |
