[Gargron]

Fix #11186

[tateisu]

(1a)
Galaxy S10's default voice recorder makes "*.m4a" file, but it's file header indicates it is "3gp4".
Sending it from WebUI on Chromw(Windows), its Content-Type header is "audio/x-m4a".
Mastodon returns 422 {"error":"バリデーションに失敗しました: Filehas contents that are not what they are reported to be, Fileは不正な値です, File content typeは不正な値です"}

Sending it from Subway Tooter, but Android's Media Scanner handles it is video, SAF content chooser show it as greyed and unselecteble.

[tateisu]

Also I have tried WebUI on Chrome(Android).
it sent multipart request with following header part .
in this case AAC's Content-Type is different to Chrome(Windows).

Content-Disposition: form-data; name="file"; filename="gs10plus.m4a"
Content-Type: audio/x-m4a

Content-Disposition: form-data; name="file"; filename="gs10plus.aac"
Content-Type: audio/aac

Content-Disposition: form-data; name="file"; filename="gs10plus_2.m4a"
Content-Type: audio/x-m4a

Content-Disposition: form-data; name="file"; filename="gs10plus.3gp"
Content-Type: video/3gpp

[tateisu]

testdata.zip

[tateisu]

my test server uses Docker, the Dockerfile is based on FROM ubuntu:18.04.

but file command in ubuntu 18 does not support 3gp file header.

$ cat /etc/issue
Ubuntu 18.04.2 LTS \n \l
$ file -i *
gs10plus_2.m4a: audio/x-m4a; charset=binary
gs10plus.3gp:   application/octet-stream; charset=binary
gs10plus.aac:   audio/x-hx-aac-adts; charset=binary
gs10plus.m4a:   application/octet-stream; charset=binary

[tateisu]

Ubuntu 19.04's file command detects "video/3gpp" for 3gp audio file.
It's better than Ubuntu 18.04, but still we need some special case for this type.

# cat /etc/issue
Ubuntu 19.04 \n \l
# file -i gs*
gs10plus.3gp:   video/3gpp; charset=binary
gs10plus.aac:   audio/x-hx-aac-adts; charset=binary
gs10plus.m4a:   video/3gpp; charset=binary
gs10plus_2.m4a: audio/x-m4a; charset=binary

Cannot upload m4a audio causes 422 video has no video stream
