[Libav-user] [libav-user] Memory leak in Mac OS X Lion

[Quy Pham Sy]

Hi,

I made a simple console test base on Dranger 's tutorial code by
replace deprecated function by the new versions.
here the full source code:

https://github.com/phamquy/FFmpeg-tutorial-samples/blob/master/tutorial01.c

It works fine, but there is a huge memory leak (i use Instrument to
for leak detection).
It seem like the leaks caused by the while loop,
there is no leak after i commented out this part:


    i=0;
    while(av_read_frame(pFormatCtx, &packet)>=0) {
          if(packet.stream_index==videoStreamIdx) {
            avcodec_decode_video2(pCodecCtx, pFrame, &frameFinished, &packet);

            if(frameFinished) {
                static struct SwsContext *img_convert_ctx;
                int w = pCodecCtx->width;
                int h = pCodecCtx->height;
                img_convert_ctx = sws_getContext(w, h, pCodecCtx->pix_fmt,
                                                 w, h, PIX_FMT_RGB24,
                                                 SWS_BICUBIC, NULL, NULL, NULL);

                sws_scale(img_convert_ctx, (const uint8_t * const
*)pFrame->data,
                          pFrame->linesize, 0, pCodecCtx->height,
                          pFrameRGB->data, pFrameRGB->linesize);

                if(++i<=5)
                    SaveFrame(pFrameRGB, pCodecCtx->width, pCodecCtx->height,
                              i);
            }
        }
        av_free_packet(&packet);
    }


What is wrong with this code?

Thanks
