The audio decoder example below fails to decode any file

(mp3, opus, wav).....<br>

[mp2 @ 0x55d075c3d780] Header missing<br>

<div>Hello,</div>
<div><br>
</div>
<div>The audio decoding example specifically uses the MP2
audio codec to decode the audio.</div>
<div>It does this:</div>
codec = avcodec_find_decoder(AV_CODEC_ID_MP2); </div>
</div>
</div>

<p>Hi Jaka,</p>
<p>I've tried changing it to <br>
</p>
<p>AV_CODEC_ID_MP3</p>
<p>error = [mp3 @ 0x56136ad2f780] Header missing<br>
<br>
</p>
<p>AV_CODEC_ID_OPUS</p>
<p>error = [opus @ 0x55caa0cb7200] Error parsing Opus packet header.<br>
</p>
<p>I've noticed that the packet size is always 0 after calling
av_parser_parse2(). It would be nice to have an example for
avcodec_send_packet() and avcodec_receive_frame() that works.</p>
