Â  Â  Â  Â  Anybody had any luck finding sample code that uses the 3.0 API<br>

Â  Â  Â  Â  There was some traffic back in June that just seemed to end...<br>

Â  Â  Â  Â  Thanks<br>

<br>

Â  Â  AFAIK, the 3.0 API does not work.Â  That is codecpar (which works but<br>

Â  Â  is missing some stuff for encoding) and av_send_packet(),etc. which<br>

Â  Â  do not work at all.<br>

Â  Â  I suggest you wait until ffplay/ffmpeg get translated to that new<br>

Â  Â  api before you try it yourself.<br>

<br>

What is codecpar ? I have never heard of it.<br>
