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. Bug: webp:603 Change-Id: Ic258381ee26c8c16bc211d157c8153831c8c6910 (cherry picked from commit a486d800b60d0af4cc0836bf7ed8f21e12974129)
