  av_malloc – mem leak

  Posted by Reichel Bart on July 18, 2011 at 11:17 am

  Hi,

  I try to debug part of code from sample an I do not know why I have strange memory leak. In one function I have

  buffer = (uint8_t *)av_malloc(numBytes * sizeof(uint8_t));
  av_freep(buffer);

  this works great I do not have any mem leak. But when I put one line

  buffer = (uint8_t *)av_malloc(numBytes * sizeof(uint8_t));
  memset(buffer, 0, numBytes * sizeof(uint8_t));
  av_freep(buffer);

  memory leaks very fast … (same if I put av_mallocz) and of course with avpicture_fill and sws_scale

  Could you help me ? Is this functions depend on something other (memset destroy mem align ?!) ? I do not see special av_ function for doing this.

  thank you
