Subject: [PATCH] EncodeAlphaInternal: clear result->bw on error
|
|
||||||
|
|
||||||
This avoids a double free should the function fail prior to
|
|
||||||
VP8BitWriterInit() and a previous trial result's buffer carried over.
|
|
||||||
Previously in ApplyFiltersAndEncode() trial.bw (with a previous
|
|
||||||
iteration's buffer) would be freed, followed by best.bw pointing to the
|
|
||||||
same buffer.
|
|
||||||
|
|
||||||
Since:
|
|
||||||
187d379d add a fallback to ALPHA_NO_COMPRESSION
|
|
||||||
|
|
||||||
In addition, check the return value of VP8BitWriterInit() in this
|
|
||||||
function.

|
||||||

||||||
