Cannot use tee muxer with libsvtav1

[Joe Amenta]

Summary of the bug:

I originally found this with a much more complicated command-line (i.e., one that makes more interesting use of the tee muxer), but I've reduced it down to this.

When I send a libsvtav1 encoded stream directly to an output file, ffmpeg consistently processes it as expected. See attached FFREPORT log file 'CODEC:libsvtav1_OUTPUT:file_SUCCESS.log'

When I send a libvpx-vp9 encoded stream through the tee muxer, ffmpeg consistently processes it as expected. See attached FFREPORT log file 'CODEC:libvpx-vp9_OUTPUT:tee_SUCCESS.log'

When I put the two together and try to send a libsvtav1 encoded stream through the tee muxer, ffmpeg consistently reports error 'av_interleaved_write_frame(): Invalid data found when processing input' and terminates immediately. See attached FFREPORT log file 'CODEC:libsvtav1_OUTPUT:tee_FAILURE.log'

How to reproduce:

% ffmpeg -f x11grab -video_size 2560x1440 -framerate 25 -i $DISPLAY -r 25 -c:v libsvtav1 -preset 7 -crf 30 -map 0 -f tee '[select=v]test.mkv'
