<pre>Look at av_dict_get() and av_dict_set() API</pre>
<pre>Ex: av_dict_set(&program->metadata, "service_provider", p2, 0); for example mpegts file</pre>

<div>Hello,</div>
<div> </div>
<div>I want to write a tag Genre=Classic in an aac file using ffmpeg API functions, I don't know how to do, and I did not find any useful example in the folder of source ffmpeg>doc>examples, there is only an example file named metadata.c which it iterates the metadata tags by using 4 API functions: avformat_open_input(), avformat_find_stream_info(), av_dict_iterate(), avformat_close_input(). I also searched online, and no results.</div>
<div> </div>
<div><br/>
Who could give me some examples of how to write a tag in the auido file using the FFMPEG API? Thank you for your help!</div>
<div> </div>
<div>Regards,</div>
<div>Ben</div>
