.mp4 file not detected
dcelasun opened this issue · comments
See attached file (Github doesn't let me upload a video, so it's in a zip).
file
doesn't recognize the mime type either:
$ file --mime-type vid-20180326-wa0000.mp4
vid-20180326-wa0000.mp4: application/octet-stream
$ file vid-20180326-wa0000.mp4
vid-20180326-wa0000.mp4: ISO Media
It plays fine with VLC. Here's the part I thought looked relevant:

We also have a similar issue where a mp4 video taken from a device isnt detected. This is the output from ffmpeg

When we do a file on this mp4, it outputs
192:Downloads raja$ file ~/Downloads/WhatsApp\ Video.mp4
/Users/raja/Downloads/WhatsApp Video.mp4: ISO Media, MPEG-4, MOBI format
But for a file that is accepted by a tool, the output is
192:Downloads raja$ file ~/Downloads/Client\ logged\ into\ Nisha\ PC.mp4
/Users/raja/Downloads/Client logged into Nisha PC.mp4: ISO Media, MP4 Base Media v1 [IS0 14496-12:2003]
It looks like the MPEG-4,MOBI format isnt detectable by the tool.
Is there anything that can be done to upload these files?
I'm also facing a undetectable mp4 file
