Comment (by dgillier):

 Check the 020 or any previous file and you will have a much higher data
 rate (that has nothing to do with silence...).

 It seems that the problem is a bit more tricky.

 The .mp4 file generated by the segmenter are not correct. They don't have
 the correct header in place.
 The file 0.mp4 is readable, but all the others are not, for a reason I
 don't know..
 VLC and other are displaying a black screen with no audio.

 If with the initial segmented files you add a  ffmpeg -i segmentfiles-
 xxx.mp4  -c copy -y newfile-xxx.mp4, afterward, the new files are correct
 and readable.
 But all the files after the 024 one, have false length data.
