memory leak av_codec_send_packet

[hagorms]

Summary of the bug:
when do avcodec_send_packet, av_util 5.6 allocates memory and never cleans it

How to reproduce:
{connect ip camera or open long video in h264
{
while (1)

{
av_read_frame(m_format_ctx_ptr, m_packet);
const int res = avcodec_send_packet(m_codec_ctx_ptr, m_packet);
if (res != 0) {

return;}

while (avcodec_receive_frame(m_codec_ctx_ptr, m_picture_ptr) == 0)

{

const int err_height = sws_scale(m_img_convert_ctx_ptr,

m_picture_ptr->data, m_picture_ptr->linesize, 0,

m_codec_ctx_ptr->height,

m_picture_rgb_ptr->data, m_picture_rgb_ptr->linesize);

av_frame_unref(m_picture_ptr);
}

}

}}

memory releases when I do :
avcodec_flush_buffers(m_codec_ctx_ptr);
avcodec_free_context(&m_codec_ctx_ptr);
