  7 mars 2024, par Erin

  If you can’t get leads, you can’t get customers. To ensure you always have a steady stream of new customers (and revenue), you need to equip yourself with lead generation tools.

  Lead gen software does the heavy lifting for you so you can focus on providing great products and great services. With it, you’ll be able to turn more strangers into customers and grow your business.

  And you don’t need a ton of tools to get the job done, either. Consolidating your tech stack to a few select tools will help you get more done in less time (and with less confusion).

  In this article, we’ll analyse the top seven lead generation tools to help you grow your business in 2024.

  Let’s dive in.

  What is a lead generation tool ?

  Lead generation tools are great levers you can pull to drive high-quality leads. They remove the grunt work by automating the lead generation process. 

  Whether it’s through creating lead magnets, offering conversion rate analytics, helping you create high-quality forms or automating the lead follow-up process, lead generation tools can bring in new customers to grow your business.

  Coupled with CRO tools, certain testing tools and web analytics tools play a crucial role. They offer insight into user behaviour patterns, enabling businesses to choose effective strategies. By understanding what resonates with users, these tools help inform data-driven decisions. This allows businesses to refine online strategies and enhance the customer experience.

• ffmpeg/libavcodec memory management

  23 juillet 2015, par Jason C

  The libavcodec documentation is not very specific about when to free allocated data and how to free it. After reading through documentation and examples, I’ve put together the sample program below. There are some specific questions inlined in the source but my general question is, am I freeing all memory properly in the code below ? I realize the program below doesn’t do any cleanup after errors — the focus is on final cleanup.

  The testfile() function is the one in question.

  extern "C" {
  
  #include "libavcodec/avcodec.h"
  
  #include "libavformat/avformat.h"
  
  #include "libswscale/swscale.h"

      }
  
  
  
      testfile(argv[1]);
  
  
  
  }
  
  </cstdio>

  Specific questions :

  1. Is there anything I need to free in the frame processing loop ; or will libav take care of memory management there for me ?
  2. Is av_free the correct way to free an SwsContext ?
  3. The frame loop exits when av_read_frame returns < 0. In that case, do I still need to av_free_packet when it’s done ?
  4. Do I need to call av_free_packet every time through the loop or will av_read_frame free/reuse the old AVPacket automatically ?
  5. I can just av_free the AVFrames at the end of the loop instead of reallocating them each time through, correct ? It seems to be working fine, but I’d like to confirm that it’s working because it’s supposed to, rather than by luck.
  6. Do I need to av_free(codec) the AVCodec or do anything else after avcodec_close on the AVCodecContext ?
  7. Do I need to av_free(format) the AVFormatContext or do anything else after av_close_input_file ?

  I also realize that some of these functions are deprecated in current versions of libav. For reasons that are not relevant here, I have to use them.
