Yocto / Gstreamer 1.0 / MPEG-2 AAC decoder missing

Products Support DragonBoard410c
#1

I have installed the good/bad gstreamer plugin libs. It appears there is no AAC support in these. What package should I be using to get AAC support?

Also when building gstreamer1.0-plugins-v4l2 I get an error:
WARNING: gstreamer1.0-plugins-v4l2-1.0-r0 do_fetch: Failed to fetch URL file://0001-introspection.m4-prefix-pkgconfig-paths-with-PKG_CON.patch, attempting MIRRORS if available

To enable faad:

local.conf
PACKAGECONFIG_pn-gstreamer-1.0-plugins-bad-faad = “faad”

image.bb
gstreamer1.0-plugins-bad-faad \

#3

I think this is better:
PACKAGECONFIG_append_pn-gstreamer1.0-plugins-bad = " faad"

Gstreamer decodes an AAC source with this.

Hello,

Have you done anything for the warning (patch missing?). I think this is a bug that needs to be fixed. To avoid the build to fail I add an empty file with the name of the missing patch in the meta-qcom/receipes-multimedia/gstreamer/files (this patch is already applied in oe/meta/recipes-multimedia/gstreamer).

Jérôme.

The issue with gstreamer1.0-plugins-v4l2 is out standing, and needs to be fixed.

#6

hi,

we just merged in our sample distro:

so that we have gst libav plugins by default, that should take care of AAC, i believe.

it was merged for the krogoth manifest branch. However I am not completely sure what your build setup/env is. So any additional details you can provide would help (typically for OE issues, if you can paste the output of the bitbake command that helps a lot).

This is the issue with v4l2 from master of “https://github.com/ndechesne/meta-qcom”. The patch file is getting appended to the SRC_URI in gstreamer1.0.inc:

SRC_URI_append = " \
    file://0001-introspection.m4-prefix-pkgconfig-paths-with-PKG_CON.patch \
"

the v4l2 plugin has just been removed from master branch, as i want to deprecate it anyways…
