Packages affected: gst-openmax
Gst-openmax is a GStreamer plug-in for OpenMAX IL API (http://cgit.freedesktop.org/gstreamer/gst-openmax/).
This spec intend to make gst-omx compatible with multi vendor OpenMax (OMX) implementations.
OMX implementation are very segmented today and each vendor have it own version the gst-openmax to fit with. A unique version of gst-openmax will request less effort to maintain over gstreamer evolutions and avoid fragmentation.
All vendors use OMX bellagio core and have OMX audio/video decoder/encoder. gst-openmax version will be at least 0.10.1
- Define a list of gstreamer parser/demuxer/muxer to investiguate their interactions with OMX compoments
- avidemux / avimux
- flvdemux / flvmux
- qtdemux /qtmux
- asfdemux / asfmux
- Import zero copy spec into gst-openmax
- add unitary test suite in gst-openmax
- Define which input parameters are needed by OMX for each format
add unitary test plan in gst-openmax
provide test files for each format (h264,h263,mpeg4 and mp3,aac)
The following sequence diagrams propose a new implementation of gst-openmax to allow zero copy between OMX element:
Bellagio OMX components conformance:
- mp3 (libmad)
- Compatible with mp3parse
- Compatible with avidemux
