Hi all,

Sorry for the cross-post but I want this to have a wide audience.

For the 1.7 release I want to move GStreamer 0.10 from oe-core into
meta-multimedia, and ensure everything in oe-core has ported to
GStreamer 1.x. GStreamer 0.10 is considered dead upstream and is
unmaintained so we don't need to be shipping both versions anymore.

Everyone in agreement? Should I expect any hate mail over this?

The next question is does that mean for the "old" libav (which
depends upon), do we move that as well or drop it?
libav was migrated to oe-core quite recently and there is couple of
recipes in meta-oe, meta-webserver depending on it/ffmpeg so moving to
meta-multimedia wouldn't be very easy.

meta-multimedia/recipes-multimedia/sox/ = "libpng
libav libsndfile1"
meta-multimedia/recipes-mediacentre/xbmc/ = "libusb1
libcec libplist expat yajl gperf-native libxmu fribidi mpeg2dec ffmpeg
samba fontconfig curl python libass libmodplug libmicrohttpd wavpack
libmms cmake-native libsdl-image libsdl-mixer virtual/egl mysql5
sqlite3 libmms faad2 libcdio libpcre boost lzo enca avahi
libxinerama libxrandr libxtst bzip2 virtual/libsdl jasper zip-native
libtinyxml libmad"
meta-multimedia/recipes-multimedia/musicpd/ =
"alsa-lib libsamplerate0 libsndfile1 libvorbis libogg faad2 ffmpeg curl
sqlite bzip2 pulseaudio" meta-multimedia/recipes-multimedia/vlc/
faad2 ffmpeg flac libxpm libxinerama fluidsynth alsa-lib libdvdcss \

S =
"flac libav jpeg sqlite3 libexif libogg libid3tag"
meta-oe/recipes-support/opencv/ ??= "eigen
jpeg libav png tiff v4l"
meta-oe/recipes-graphics/gegl/[avformat] =
meta-oe/recipes-multimedia/libpostproc/ =
meta-oe/recipes-multimedia/mplayer/ = "libvpx
libdvdread libtheora virtual/libsdl ffmpeg xsp zlib \

fmpe g] = "--with-ffmpeg,--without-ffmpeg,libav"

But I would like to see migration to libav-9 which currently has
D_P (mplayer2 already depends on 9*, but there are few recipes which
with libav-9 too - see earlier world builds for list).
Yes, I'm just talking about libav 0.8 here - libav 9 would remain where it
is. That might still be problematic though given that their PN is the
same. I'm open to better suggestions, but I think we have to do
*something* here.
Ah ok, I though you meant both versions.

Then I would rather drop 0.8 completely, otherwise it will be preferred
even with negative D_P from meta-multimedia (YOCTO #2964) and we cannot
expect people which happen to have meta-multimedia layer to know that
they are expected to update P_V everytime libav is updated in oe-core.
Hmm. Perhaps a less intrusive solution then would be to create a completely
separate meta-gstreamer0.10 layer for those that still really need it rather
than putting it in meta-multimedia?
