--- Comment #87 from Matthieu Bouron <matthieu.bouron at gmail.com> ---
Here is the current status of the patchset:
  * the feature is working on broadcom devices (nexus 4 and 5 on android >=
4.4)

  * gl output is not properly negotiated under decodebin (#742924) and thus the
decoder falls back to main memory output if amcvideodec supports all the
relevant color formats (and it is unlikely as android 5.0 introduces new color
formats such as COLOR_QCOM_FormatYVU420SemiPlanar32mMultiView). To work around
this issue GST_AMC_IGNORE_UNKNOWN_COLOR_FORMATS should set to "yes".

  * an user reported that the patchset was not working on a tegra2 device
(whereas it was working on his broadcom device). I suspect the issue to be on
the GL side but I can't tell much as I don't have this kind of device. I'm
trying to debug the issue remotely but I don't know how many time it will take.
