Running MP4Box -add 4.mp4 41.mp4, MP4Box -inter 0 4.mp4 or MP4Box -add 4.h265 41.mp4 show exceptions such as:.

Running qtfaststart 4.mp4 41.mp4 throws the moov atom not found, is this a valid MOV/MP4 file? exception.

But none of them seemed to solve the issue. Google search led me to tools such qtfaststart and mp4box. moov atom not foundĤ.mp4: Invalid data found when processing input But ffmpeg throws these exceptions irrespective of the operation I try to perform: Format mov,mp4,m4a,3gp,3g2,mj2 detected only with low score of 1, misdetection possible! I thought re-encoding it with ffmpeg might solve the issue. It's actually a 2hr 49min 10sec long video. It doesn't seem to contain any metadata or codec information either.
