<div><span style="color: rgb(0, 0, 0); background-color: rgba(0, 0, 0, 0);">Hi, I want to use lib APIs to implement below ffmpeg cmd and I don't know where to start:</span></div>

<div><span></span><span style="color: rgb(0, 0, 0); background-color: rgba(0, 0, 0, 0);">ffmpeg -f concat -i mylist.txt -c copy output.mp4</span></div>
<div><br>
</div>
<div>I tried to read the source code directly but it a headache and I can't even go through the ffmpeg.c </div>
<div><br>
</div>
<div>I'm not sure is there any way to single step debug the ffmpeg process then I could see the execute path...</div>
<div><br>
</div>
<div>Could anyone tell me what APIs the cmd use or <span style="font-size: 10.5pt; line-height: 1.5; background-color: window;">give some instructions about how to map a cmd to lib APIs or some tips to read the source code?</span></div>
