#4138: Lavfilter output cyclically the same frame when using trim filter with
pipe

Summary of the bug:
How to reproduce:
ffmpeg -i input -map 0:v -c:v rawvideo -f yuv4mpegpipe -vf
trim=start_frame=240 - | x265 --input - --y4m --output output
The output has cyclically the same frame. FFmpeg and x265 don't produce
errors or warnings; if log is pretty necessary ask me and I'll provide to
add it.
However using this syntax the output works fine:
ffmpeg -i input -map 0:v -c:v libx265 -vf trim=start_frame=240 output
