Hi everyone,
I’m Home Software Enabling engineer of ARM Shanghai and working on multimedia. I have paid attention to Linaro multimedia projects from wiki and mail list for several months.
I found that Linaro 1105 released and didn't include multimedia projects. Is the schedule of multimedia project changed?
Best Regards,
Fang Bao

All,
In context of a vc1 parser, I've posted the Annex L section from the
vc-1 spec. This describes the format that is used by TI vc-1 decoder
for simple and main profile.
https://docs.google.com/a/linaro.org/viewer?a=v&pid=explorer&chrome=true&sr…
Advanced profile is something different... just a start code. I'm not
entirely sure offhand the name for the format used for
advanced-profile, but it is different from simple/main profile.
Also, here is the relevant code from the GStreamer plugin for TI VC-1 decoder:
https://github.com/robclark/gst-ducati/blob/master/src/gstducativc1dec.c#L1…
We need to somehow:
a) identify if there are any other possible formats that decoders expect
b) choose caps field name(s) and values to uniquely identify the
different formats, so a vc1parser element could do the necessary
conversion
BR,

I want to join the group

Hi,
I got a suggestion (from a ST-E colleague) to help debug with futur UMM.
The idea is to add a "comment" to each allocated buffer
and with cat /proc/umm you get a list of all the allocated buffers + the
associated comment.
The comment is only a string and you can put what you want it.
For example you can just put the line of the file where the allocation is
done or something like "h264 1080p frame".
I think it could be very useful for debug if we could add this.

As we discussed in today's MMWG technical status call, Vishal is working on
a test content spec, which led to producing a chart of the multimedia format
capabilities of all the Linaro supported development boards. This is similar
to what I started for audio, but I think it makes sense to cover all
multimedia formats. Vishal, if you could create a wiki page for us to
populate, that would be great.
Here is a great example from Android, I'd like to see us produce something
like this: http://developer.android.com/guide/appendix/media-formats.html
I would like for us all to contribute to this capabilities chart. It won't
take long if we all contribute. If you can find out the specifics on a board
that uses your companies technology, or if you have the specs to a dev board
you can get your hands on, or if you can contact someone you know, please
do. This would be a very useful reference chart for everyone wanting to use
or develop on these platforms.
The blueprint for this work is at:
https://blueprints.launchpad.net/linaro-multimedia-wg/+spec/multimedia-lina…
Alexander could you assign this to Vishal?
If you missed today's MMWG tech call, we missed you. Please plan on
attending next week. I'll send out a reminder in advance.
