MP4 recording can't be imported in Adobe Premiere (recorded with v2.2 or v2.3)

[TKooijmans]

When I setup a recording like this
ADD 1 FILE "myfile 1.mp4" -codec:v libx264 -crf:v 23 -preset:v veryfast -filter:v format=pix_fmts=yuv420p,tinterlace=4 -flags:v +ildct+ilme -codec:a aac -b:a 128k -ar:a 48k

I get a mp4 file with 8 channels audio.
This file does not import in Adobe Premiere, only audio is accepted not video.
Are the ffmpeg parameters changed again?
Are there good examples for stereo or 4 channel recordings?
