 **Summary of the bug:**
 FFmpeg is running infinitely when using alphamerge filter with input video
 file and nullsrc.

 **Bisected commit:**
 https://github.com/FFmpeg/FFmpeg/commit/88db1745fc3b99cd8df000baa0b1af9ee2bac4ac

 //Issue is reproducible// since FFmpeg v4.4 and also in the current HEAD.

 //Issue is not reproducible// when you use 2 files as the input for
 alphamerge filter.

 **How to reproduce:**

 Create an empty video with duration 3.03 seconds:
 {{{
 $ ffmpeg -t 3.03 -filter_complex 'color=red:size=480x270' -c:v libx264 -r
 30 input.mp4
 }}}

 Use alphamerge with this file and nullsrc:
 {{{
 $ ffmpeg -y -i input.mp4 -filter_complex 'nullsrc=size=480x270, loop=-1:1
 [v_1]; [0:v:0] [v_1] alphamerge [v_2]' -map '[v_2]' -c:v:0 libx264 -preset
 veryfast output.mp4
