When af_scaletempo2.c:process() detects a format change, it goes back through mp_scaletempo2_init() to reinitialize everything. However, mp_scaletempo2.input_buffer is not necessarily reallocated due to a check in af_scaletempo2_internals.c:resize_input_buffer(). This is a problem if the number of audio channels increases, since without reallocating, the buffer for the new channel(s) will at best point to NULL, and at worst uninitialized memory. Since resize_input_buffer() is only called from two places, pull size check out into mp_scaletempo2_fill_input_buffer(). This allows each caller to decide whether they want to resize or not. We could be smarter about when to reallocate, but that would add a lot of machinery for a case I don't expect to be hit often in practice. |
