nut muxed with ffmpeg is missing index at the end

[Elon Musk]

And ffplay reports read_timestamp failed if you try to seek

At least one output file must be specified

[Michael Niedermayer]

The index isnt mandatory but seeking with ffplay should not fail
is this a regression ?

[Elon Musk]

That was my first muxing into nut, so I can not answer that.

Reported duration from ffplay is invalid (14 minutes but should be ~3), seeking works somehow but it is buggy causing mplayer2 to crash it I try to seek past end of stream.

[Carl Eugen Hoyos]

Seeking with ffplay works fine here with the output file and current git head.

Duration was shown as "N/A" until r21971 (6f5a3d0a), an incorrect value is shown since r21972 (b7884740)

Replying to cehoyos:

cant reproduce, duration is N/A here

I can confirm that the wrong duration is not shown anymore.
