problems with astreamselect

Eric Ball
Thought I'd check with the mailing list before filing a bug report.

ffmpeg version 4.1.1-tessus on macOS 10.14.5

test.mp4 contains 3 streams :0 h264, :1 aac, :2 aac

ffmpeg -i test.mp4 -filter_complex:a "astreamselect=inputs=2:map=1" test.wav

ffmpeg locks up after producing minimal output.

(Yes, I know I can accomplish this with -map, but I want to use
asendcmd to change the map at set times.)

Adding -vn before -i doesn't help.  But if I extract the two streams
to individual wav files it works fine.

Only git head is supported here, Eric.
Retry with the current git head and report back.

4.1.1 is almost current (IIRC 4.1.3 is the current tagged version), but
please post the complete/uncut command output.

Reproduced with ffmpeg version N-94000-g78e1d7f421-tessus

However, I was hoping the mailing list could identify any obvious
usage problems before I generated the bug report.

Use asetnsamples to set same number of samples to both inputs.

No impact.

I'm beginning to wonder if it's something with the container.  If I
strip the video out so the mp4 only contains the two audio streams it
still fails.
