Memory leak when specifying invalid channels count
Hi
I minor issue I noticed when I passed an invalid 'channels' parameter
to celt_encoder_create() is that celt_encoder_init() doesn't free
the CELTEncoder ('st' parameter) when 'if (channels < 0 || channels > 2)'
evaluates to true.
Seems celt_encoder_init() should do like this instead:
CELTEncoder *celt_encoder_init(CELTEncoder *st, const CELTMode *mode, int
channels, int *error)
{
if (channels < 0 || channels > 2)...

It seems quite strange that it would loop okay without the "trick" but
not with it.<br>

[RFC PATCH v1] Decode(float) optimize using libNe10
Hello All,
I extended the libNE10 optimizations for float towards
mdct_backwards/opus_ifft.
I am able to get about 14.26% improvement for Decode use
case now on my Beaglebone Black. Please see [1] for measurements.
Questions
1. Since this patch needs to go in after Encode [2] patch)
should I submit this as patch series?
2. Since Jonathan Lennox posted intrinsics cleanup [3]
patch, should

[RFC PATCHv3] Encode optimize using libNe10
Changes from RFC PATCH v2
- fixed compile issue when just compiling for --enable-intrinsics
for ARMv7 without NE10
- Notes for NE10:
- All compile/link warnings are now in upstream NE10
- Only patch pending upstream in NE10 is the one that
needs to add -funsafe-math-optimizations for ARMv7
targets.
- Phil Wang @ ARM is working on getting this fixed.
- Note that even without
