Help finding a memory leak

Question

C++ / C#

Memory leaks in functions:

static int xxxx_read_packet(AVFormatContext *s, AVPacket *pkt)
{
    struct xxxx *xxxx = s->priv_data;
    
    CFDataRef bitmapDataRef = CGDataProviderCopyData( CGImageGetDataProvider( xxxx->image ) );
    uint8_t *imgData = (uint8_t *)CFDataGetBytePtr( bitmapDataRef );

    av_init_packet( pkt );

    pkt->data = imgData;
    pkt->size = xxxx->frame_size;
    pkt->pts = curtime;

    CGImageRelease( xxxx->image );
    //CFRelease( bitmapDataRef );

    xxxx->image = CGWindowListCreateImage( CGRectInfinite, kCGWindowListOptionAll, kCGNullWindowID, kCGWindowImageDefault );

    return xxxx->frame_size;
}

I can't figure out where, please help.

Answer 1

Thank you all, the problem is crooked, but solved.

Answer 2

Here is a similar question: stackoverflow.com/questions/11992791/ios-potential-leak-of-data-cfdatagetbyteptr
There seems to be a similar situation. Copy the data, and then call CFRelease, which is now commented out for some reason.

Answer 3

av_free_packet(pkt) must be called if xxxx_read_packet is not called after calling xxxx_read_packet.

Answer 4

memwatch . Small and comfortable. I use them all the time.
