<div><br>
</div>
<div>I tried to do it but it is not helped me...</div>
<div><br>
</div>
<div>The flow you wrote helps when I am decoding packets/frames.</div>
<div><br>
</div>
<div>looks likes the read packet/frame methods are for the
codecs themselves.</div>
<div><br>
</div>
<div>I am trying to find some code that gives me the == TS
packets == and its fields (continuity counter, scramble bit
etc...)</div>
<div><br>
</div>
<div>Also, the example that I saw under doc/sample in the ffmpeg
package are mostly for decode/transcode/encode and I didnt see</div>
<div><br>
</div>
<div>any API that gives me handling of the TS packets
themselves.</div>
<div><br>
</div>
<div>can you please be more specific with some example that I
can look on.</div>
<div><br>
</div>
<div>Thank you very much</div>

<div>In avcodec library, the AVPacket structure seems to
provide your needs.</div>

<div>To parse each packet you'll need to:</div>
<div>- Register codecs</div>
<div>- Open file</div>
<div>- Read frame (AVFrame structure)</div>
<div>- Read packet</div>
<div>- Extract what you need.</div>
<div><br>
</div>
<div>Plenty of examples in the FFMPEG sources.</div>
<div><br>
</div>
<div>Good luck.</div>

That would be somthing like DVB snoop. with -s ts flag I believe. Or
MPEG-2 packet analyzer if you need a gui<br>
