I guess I’m just talking to myself here, but thought I would close this thread
with a report of how I solved the problem. After trying hundreds of things, I
found the solution in a very old post by Carl Eugen, replying to someone who
had buffer queue overflows for a completely different reason.
I simplified the commands to highlight the problem and increase the chance of
getting help here. With my limited knowledge, it seems that the acrossfade
filter interferes with video.
Here is a command for two 10-second clips, cross-fading video and audio between
for two seconds. No error or wa
By the way, it’s exactly the same when I take out the asetpts filters. I guess
they were doing nothing, because acrossfade concatenates more are less, as Paul
Mahol said. But I don’t understand how the audio filter can mess up the video.

I am attempting to use ffmpeg to develop a finished video from raw video, with
fading audio and video in at the beginning, crossfading them between clips, and
fading them out at the end. I have three, 10-second clips for testing
(actually came out to 10.04, 10.04, and 10.01). For some earlier
