Diego Biurrun	aaf47bcde7	Drop ALT_ prefix from BITSTREAM_READER_LE name. The prefix is a historic remnant that probably meant "alternative". Now that the A32 bitstream reader has been dropped it makes no sense anymore.	13 years ago

Stefano Sabatini	4f2954e232	smacker: remove unnecessary call to avctx->release_buffer in decode_frame() The release_buffer was cleaning the provided frame, thus causing the successive call to avctx->reget_buffer() to allocate a new frame. In case the returned frame was not the same one previously returned but a new one with different data, it resulted in artifacts. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
