Open tasy5kg opened this issue 2 years ago • 2 comments

FFprobeKit.getMediaInformation("av1_encoded_video.mkv").mediaInformation will returns null, even if the media information can be read.

saf:26.mkv is the AV1-encoded video sample above.

Code fragment:

FFprobeKit.getMediaInformation("saf:26.mkv")

Result:

Code fragment:

FFprobeKit.getMediaInformation("saf:26.mkv").mediaInformation

Result:

null

Expected behavior

FFprobeKit.getMediaInformation().mediaInformation could prase correct AV1-encoded video infomation.

Environment

  • Platform: Android
  • Architecture: arm64-v8a
  • Version: com.arthenica:ffmpeg-kit-min:4.5.1-1
  • Android Studio version: 2021.2.1 Patch 2

In our Android API, FFprobeKit.getMediaInformation("av1_encoded_video.mkv").mediaInformation is not a valid call., FFprobeKit.getMediaInformation() returns a MediaInformationSession object. And that class doesn't have a public field or method named mediaInformation. We do have getMediaInformation() to get the media information extracted. I suggest using that.

Anyway, there is an issue there but I'm not sure how to resolve this. The ffmpeg-kit package you use don't have an av1 decoder inside. Because of that ffprobe prints those [av1 @ 0xb400007ae42abc00] Missing Sequence Header. lines which breaks the parsing.

You have two options:

  1. Use an ffmpeg-kit package that has dav1d inside e.g. video, full, full-gpl. They don't fail and process the av1 headers successfully
  2. Use FFprobeKit.getMediaInformationFromCommand method with the following arguments. Those arguments discard the decoding errors. So, parsing never fails.
FFprobeKit.getMediaInformationFromCommand("-v quiet -hide_banner -print_format json -show_format -show_streams -show_chapters -i " + url);

I'll let you know if I find a more elegant solution.

@tanersener , thank you for your patience in replying.

Sorry, I didn't specify it. FFprobeKit.getMediaInformation("av1_encoded_video.mkv").mediaInformation is property access syntax in Kotlin. It equals FFprobeKit.getMediaInformation("av1_encoded_video.mkv").getMediaInformation() in Java.

Your methods does work. Thanks again for your reply.

fixed on the development branch.
