[FFmpeg-user] Error ‘can’t open stats file’ using 2 pass encoding with multiple audio inputs

Hi,

Here's the input commands boiled down to the simplest reproducible
versions.

Here's links to the input files https://s3.amazonaws.com/Jlangston/bunny.mp4
https://s3.amazonaws.com/Jlangston/track1.m4a
Trying either without the 2nd audio input or without rendering multiple
video versions with multiple audio tracks seems to work but the combination
of multiple input audio tracks and multiple output versions is hitting.
Which I am guessing might be around the usage of the -passlogfile option.

[libx264 @ 0x5562fa469c80] ratecontrol_init: can't open stats file
Error initializing output stream 0:2 -- Error while opening encoder for
output stream #0:2 - maybe incorrect parameters such as bit_rate, rate,
width or height

If I leave out the -passlogfile option I get a message about failure to
rename log file in pass1.

[libx264 @ 0x5621f1bcdfc0] failed to rename "ffmpeg2pass-0.log.temp" to
"ffmpeg2pass-0.log"
[libx264 @ 0x5621f1bcdfc0] failed to rename "ffmpeg2pass-0.log.mbtree.temp"
to "ffmpeg2pass-0.log.mbtree"

Here's the commands and their outputs below. Thank you in advance for any
assitance or guidance you might be able to provide as well as everyone's
work on ffmpeg.
