1799,movie: loop option doesn't seem to work,ubitux,,"Given a small video stream:

{{{
./ffmpeg -f lavfi -i testsrc=d=5 -y loopme.mkv
}}}

And trying to loop it N times until the output reaches a given duration:

{{{
./ffmpeg -f lavfi -i movie=loopme.mkv:loop=0 -t 20 -y out.mkv
}}}

...leads to an infinite loop. All the frames >126 are dropped (the input has 125 frames):

{{{
frame=  126 fps= 10 q=32766.0 Lsize=      23kB time=00:00:04.96 bitrate=  38.6kbits/s dup=0 drop=59352 
}}}

Complete output:
