• Convert a video with content type video/quicktime to video/mp4 using ffmpeg

  25 June 2021, by schub

  I 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 is video/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?

  


  Versions:

  


  tika: 1.22
  
ffmpeg: 4.4

• how to configure ffmpeg pipline for streaming

  30 June 2021, by Changhoon Lee

  I want to get real-time streaming data (use mediasuop) and send it to nginx-rtmp-server via ffmpeg, but if I run it through the pipeline, the error occurs after logging as below. I checked that the rtmp server works well through OBS studio program, but when I run with the pipeline I prepared, the error occurs. Do you know where this problem occurs?

  


  Problems with the pipeline? Problem with Sdp? Or something else?
