Hi,
I use official H.264 HP encoder for C66x 1.0.0.1 version. I implemented aspect ratio change with flush like described in http://e2e.ti.com/support/embedded/multimedia_software_codecs/f/356/t/240820.aspx
After flush encoder releases wrong buffer that had been released before.

Error releasing YUV buffer in queue
To simulate the bug I change aspect ratio each 50 or 100 or 250 frames. Interesting fact that the bug disappears if I change aspect ratio each 25 frames.

Can you please check the encoder for this type of bug?
