  • Why don't VideoIntelligence end_time_offset values match for the same video ?

    3 septembre 2022, par ProGirlXOXO

    When parsing the results of Google's Video Intelligence API, I've noticed that speech_transcriptions and all other annotation results are split into two separate list items within annotation_results. See the example output below.

    


    Digging further, I've noticed they have slightly varied end_time_offset values.

    


      

    1. Why are these end_time_offset values different ? I expect them both to show the exact same value since the exact same video is being analyzed for both sets of features. In some cases this value is off by more than a second.

      2. 


    2. Assuming this is not an error, which end_time_offset I trust if I want to determine the total duration of the video ?

      3. 


    3. Why is feature output split into two different list items ?

      4. 


    


    {&#xA;    "annotation_results": [&#xA;        {&#xA;            "input_uri": "<redacted>.mp4",&#xA;            "segment": {&#xA;                "start_time_offset": {},&#xA;                "end_time_offset": {&#xA;                    "seconds": 57,&#xA;                    "nanos": 849516000&#xA;                }&#xA;            },&#xA;            "shot_label_annotations": [],&#xA;            "shot_annotations": [],&#xA;            "explicit_annotation": {},&#xA;            "text_annotations": [],&#xA;            "logo_recognition_annotations": []&#xA;        },&#xA;        {&#xA;            "input_uri": "<redacted>.mp4",&#xA;            "segment": {&#xA;                "start_time_offset": {},&#xA;                "end_time_offset": {&#xA;                    "seconds": 58,&#xA;                    "nanos": 69333000&#xA;                }&#xA;            },&#xA;            "speech_transcriptions": []&#xA;        }&#xA;    ]&#xA;}&#xA;</redacted></redacted>

  • How to process video stream ?

    27 avril 2016, par sharpener

    I would like to ask some experienced multimedia professional how to proceed with following task :

    Given URL provides video stream and we would like to get access to decoded frames (byte stream in memory) in managed Win7+ application (C#). We don’t want to render/present the frames the standard way. The video format is known but not fixed (might get changed between two successive sessions, but we will know the parameters).

    So far, I have found there are several methods and I have build following picture in my mind :

    1. ffmpeg wrapper
      • Pros
        1. Self contained (no dependency to windows technologies)
        2. Powerful
      • Cons
        1. Little more complex to understand
        2. Lot of different wrapping variants (FFmpeg.NET, ffmpeg-sharp, ffmpeg-shard, FFmpeg.AutoGen, ...)
    2. DirectShow wrapper
      • Pros
        1. Widely used/supported technology (variaous filters freely available)
        2. Nice/detailed documentation on MSDN
      • Cons
        1. Quite old
        2. Considered obsolete from the point of author’s view (available only for desktop model on runtime >= Win8)
    3. MediaFoundation wrapper
      • Pros
        1. Theoretical successor of DirectShow, so should be available in the future
      • Cons
        1. Seems to be not as good as DirectShow
        2. Not very popular, limited "community" support
    4. FFmpegInterop wrapper
      • Pros
        1. Microsoft’s open source wrapper alternative
      • Cons
        1. Not available for runtime < Win8
