The first buffer does not contain more garbage than any other MP3 decoder
outputs and we don't really know how much we have to drop or not.
After this change the output has the same duration as with mad.
gst_pad_get_pad_template_caps() returns a reference which is unreferenced,
so creating a copy using gst_caps_copy() results in a reference leak.
Also remove the incorrect comment to avoid confusion in the future.

Check if libnativehelper is loaded in the process and if
it has these awful wrappers for JNI_CreateJavaVM and
JNI_GetCreatedJavaVMs that crash the app if you don't
create a JniInvocation instance first. If it isn't we
just fail here and don't initialize anything.
See this code for reference:

On Samsung Galaxy S4 it is impossible to have more than one
hardware decoder at the same time. If we do not release it
explicitly the GC only releases it whenever the whole application
is finished not whenever the activity is finished and thus a player
will not be able to work correctly
gst_amc_color_format_copy will copy in/out a frame resides at a
GstAmcBuffer. Lots of codes in gst_amc_video_*_fill_buffer are moved to
this new function.
Some hack logic needs also to be present in create_src|sink_caps, for
working around some broken codecs. These hacks are hidden
in color_format/video_format conversion -- the prototypes of these
functions are also changed to include more args for hack judgement.
Also in case of multi-color_formats mapped to one video_format, then
map that video_format back will not give the original color_format, which
causes gst_amc_codec_configure failed with something like
'does not support color format N'.
The new prototype involves with GstAmcCodecInfo and mime, which
ensures the converted color_format is supported by the codec.
A COLOR_FormatYCbYCr to GST_VIDEO_FORMAT_YUY2 mapping is also added, in
order to work around bugs in OMX.k3.video.decoder.avc(which incorrectly
reports supporting COLOR_FormatYCbYCr, which is actually
COLOR_FormatYUV420SemiPlanar). There are already hacks for this in
gst_amc_video_format_to_color_format, gst_amc_color_format_to_video_format
and gst_amc_color_format_info_set, but the codec will still not work(be
ignored because of "has unknown color formats") without adding this mapping.
If the application is using the new ART runtime it will otherwise
load dalvik and start a dalvik VM next to the ART VM.
Does not work very well obviously.
Some audio decoders (at least the MP3 decoder on MTK based devices) outputs
raw audio in batches of multiple audio frames. We need to handle that
properly, otherwise the base class will be kind of unhappy.
Add a new color format seen on my Galaxy S3
(OMX_SEC_COLOR_FormatNV12Tiled = 0x7fc00002) to the table,
but don't actually implement it - the decoder doesn't choose it.
Remove an assert that makes the plugin fail noisily and take the app down
if it sees a color format it doesn't recognise (just skip the codec instead)
Modify the debug output when plugin scanning to print color format info to
make this sort of thing easier in the future.
Flushing the decoder invalidates all buffers, so it should be done
after quiting the decoding loop. Otherwise we can jump into
"failed_release" and stop everything
