Re: [maemo-developers] Gstreamer in 770 uses OpenMax?
Hi Pavan, No, GStreamer in the 770 doesn't use OpenMAX. Christian On Fri, 2006-07-07 at 17:12 +0530, Pavan Krishnamurthy wrote: Hi, I have a query regarding Gstreamer wrt to OpenMax APIs.

You'd want to use tremor for the decoding, since the 770 doesn't have an FPU. Also on the information track, the Tremor plugin in GStreamer 0.10 works fine on the 770.

Hi Matti, No there isn't a specific Maemo example yet. Nokia do have some plans on this in regards to Maemo, but I am not sure of the details.

Re: [maemo-developers] GStreamer and 770
Hi Matti, do you already read this? http://maemo.org/maemowiki/EnablingGstreamerSupport But ALSA support didn't work with the internal soundcard, only via a usb headset, which uses the snd-usb-audio module. Because there doesn't exists an ALSA device for the internal dsp, you have only a Dummy ALSA device which IMHO moves your data to /dev/null or something similar useful ;) So doing anything with ALSA/OSS can not work with the internal dsp. To access the internal dsp you have (using the 45 Release - a little bit old) this gstreamer plugins available: snip--- Nokia770-45:~# gst-inspect-0.8 |grep dsp dspaac: dspaacsink: DSP AAC Sink dsppcm: dsppcmsink: DSP PCM Sink dspmpeg4sink: dspmpeg4sink: DSP MPEG4/H.263 Sink dspfbsink: dspfbsink: DSP FB Sink dspamr: dspamrsink: DSP AMR Sink dspmp3: dspmp3sink: DSP MP3 Sink snip--- May be the pcm sink is sufficient for you? Another solution will be to build the esdsink yourself...
