What do "mp2" and "mpeg1video" have got to do with my config at all?

If you use libx264 you have to define profile.

Can you test this configuration?

Here are the results with that config:

Do you need any more tests for this?
I've been trying various ffserver.conf, but it seems that ffmpeg always returns to some "default" values, being mp2 for audio and mpeg1video for video..

comment:5 Changed 4 years ago by michael

it might work if you add -vcodec libx264 or something, this of course is not a proper solution

comment:6 Changed 4 years ago by lissyx

I hit the same behavior using git master branch, git describe giving n0.8-4175-g0b9a69f. Workaround suggested by michael previously works, at least I've been able to verify it with libtheora and libflv.
