[XviD-devel] Memory leak using decoder?

I am trying to use XviD in my application to decode video, and
everything appeared to be working fine until I checked memory usage. The
amount of free memory available on the system steadily declines as my
program runs. However, if I comment out the line that calls the decoder,
this huge memory waste does not occur. I am calling the decoder almost
exactly like the API example program does:
memset(&xvid_dec_frame, 0, sizeof(xvid_dec_frame_t));
xvid_dec_frame.version = XVID_VERSION;
decoder_stats->version = XVID_VERSION;
xvid_dec_frame.general = 0;
/* Input properties */
xvid_dec_frame.bitstream = buf_ptr;
xvid_dec_frame.length = new_bytes;
/* Output properties */
xvid_dec_frame.output.plane[0] = out_buffer;
xvid_dec_frame.output.stride[0] = stream_x_dim*2;
xvid_dec_frame.output.csp = XVID_CSP_YUY2;
out = xvid_decore(decoder_handle, XVID_DEC_DECODE, &xvid_dec_frame,
decoder_stats);
return out;
Is there something wrong with how I am calling the decoder? Should I be
freeing some buffer the decoder creates each frame? Or is there a known
memory leak in XviD when using YUY2 or something? As I said before,
commenting out the xvid_decore call causes the problem to go away.
Sorry, I'm pretty new to using video decoders myself like this. I would
really appreciate any advice that could help me figure this out!
Thanks,
Kyle
