You could remove -c copy, but that makes the process much slower.
Are you sure that all input videos have the same properties? Same size,
video codec, framerate, audio codec, number of audio tracks, audio
sample rate?
They are downloaded using the same ffmpeg download command which sets the video
size to 480p, like this (variables are set appropriately in the script):
ffmpeg -hide_banner -referer \"${VIDEOURL}\" -i \"${VIDEOSTR}\" -vf
scale=w=-4:h=480 -c:v libx264 -preset fast -crf 26 -c:a copy -t ${CAPTURETIME}
${TARGETFILE}
That means the audio codec, number of audio tracks and audio sample rate
could be different.
You should check those videos that don't fit together with ffprobe.
