If I set the AVPacket duration to 3,600, the warning disappears; however, I have concerns explicitly setting the duration of each AVPacket explicitly (especially if my life can be made easier by FFmpeg setting it).</span></div><div><span style="color: rgb(0, 0, 0); font-family: "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 12px; white-space: pre-wrap;"><br></span></div><div><span style="font-size: 12px; white-space: pre-wrap;">1. Should the duration of AVPacket be populated automatically? (Note: The duration is currently _always_ zero). </span></div><div><span style="font-size: 12px; white-space: pre-wrap;">2. Am I expected to populate the duration myself?</span></div><div><span style="font-size: 12px; white-space: pre-wrap;">3. Is the fact that the duration is being set to zero a symptom of incorrect values in the original AVFrame as passed to the encoder?</span></div><div><span style="font-size: 12px; white-space: pre-wrap;"><br></span></div><div><span style="font-size: 12px; white-space: pre-wrap;">Gavin.</span></div><div><span style="font-size: 12px; white-space: pre-wrap;"><br></span></div></div></body></html>
