Convert a video with content type video/quicktime to video/mp4 using ffmpeg
25 juin 2021, par schubI have a strange problem. I start with a video file recored with an iPhone. The output is
video.mov
. I convert this to mp4 using ffmpeg :

ffmpeg -i video.mov -vcodec h264 -acodec aac video.mp4


If I use a tool like exiftool to show the metadata the output for
content-type
isvideo/mp4
all seems to be correct. But my backend, which receives the video, uses a library called Apache Tika to extract the content type and the result here is :video/quicktime
.

Scala code to retrieve the content type from the file :


// byteArray: Array[Byte]

val tika = new TikaConfig()
val metadata = new Metadata()
val contentType = tika.getDetector.detect(TikaInputStream.get(byteArray), metadata)



BTW : If I use a video editing program (DaVinci Resolve in my case) I can load the video, adjust settings and explicitly set the codec to mp4, export the video and then the resulting file works and Apache Tika extract the desired content-type. This is a workaround, but it does not scale and I like to automate this process via ffmpeg.


I'm stuck here. Can anyone give me a hint what I can do ?
