Description
I'm trying to add audio silence so the audio track length matches the length of video track. But it seems not working correctly.
The input file has ~30s of video and ~1s of audio.

Replying to mrskman:
What more info do you need?
Can you double check about the audio pts? there have little audio packet in the first 5 second, so hlsenc only split by video pts which 5 seconds, there only have little audio packet in the first packet, this is not hls problem.
Note:
See TracTickets
for help on using tickets.
This is not hls problem.
