I confirm this bug. The getDuration function returns values that do not match the duration of the video.

We don't see an issue about the duration field in our test apps.

Consider sharing the logs and/or instructions to reproduce the issue if you need help. Hard to say what it is without those two.

@tanersener await FFprobeKit.getMediaInformation(fpath) .then(async (session) => { // const information = await session.getMediaInformation(); const output = await session.getOutput(); const outputJSON = JSON.parse(output); console.log(outputJSON); }) .catch(error => console.error(error));

above code returning incorrect video dimensions i.e for portrait video its returning landscape o/p for some videos O/P => {"chapters": [], "format": {"bit_rate": "20142565", "duration": "20.433900", "filename": "/data/user/0/com.abc.appname/cache999999", "format_name": "mov,mp4,m4a,3gp,3g2,mj2", "nb_programs": 0, "nb_streams": 2, "probe_score": 100, "size": "51448897", "start_time": "0.000000", "tags": {"com.android.version": "11", "compatible_brands": "isommp42", "creation_time": "2022-06-05T12:39:01.000000Z", "location": "+19.9871+073.8417/", "location-eng": "+19.9871+073.8417/", "major_brand": "mp42", "minor_version": "0"}}, "streams": [{"avg_frame_rate": "18270000/608813", "bit_rate": "20025342", "bits_per_raw_sample": "8", "chroma_location": "left", "closed_captions": 0, "codec_long_name": "unknown", "codec_name": "h264", "codec_tag": "0x31637661", "codec_tag_string": "avc1", "codec_type": "video", "coded_height": 1080, "coded_width": 1920, "color_primaries": "bt709", "color_range": "tv", "color_space": "bt709", "color_transfer": "bt709", "display_aspect_ratio": "16:9", "disposition": [Object], "duration": "20.293767", "duration_ts": 1826439, "field_order": "progressive", "has_b_frames": 0, "height": 1080, "id": "0x1", "index": 0, "is_avc": "true", "level": 40, "nal_length_size": "4", "nb_frames": "609", "pix_fmt": "yuv420p", "profile": "100", "r_frame_rate": "30/1", "refs": 1, "sample_aspect_ratio": "1:1", "side_data_list": [Array], "start_pts": 12573, "start_time": "0.139700", "tags": [Object], "time_base": "1/90000", "width": 1920}, {"avg_frame_rate": "0/0", "bit_rate": "96005", "bits_per_sample": 0, "channel_layout": "stereo", "channels": 2, "codec_long_name": "unknown", "codec_name": "aac", "codec_tag": "0x6134706d", "codec_tag_string": "mp4a", "codec_type": "audio", "disposition": [Object], "duration": "20.415688", "duration_ts": 979953, "id": "0x2", "index": 1, "nb_frames": "957", "profile": "1", "r_frame_rate": "0/0", "sample_fmt": "fltp", "sample_rate": "48000", "start_pts": 0, "start_time": "0.000000", "tags": [Object], "time_base": "1/48000"}]}

@SandipJawaleRN Your question is unrelated to the original issue reported in the first post. Please ask google about it. It is not a bug, it is just how rotation information is stored in a file.

@tanersener. First off, thank you so much for this library. It helped me a lot. The question might be unrelated but my point is how to get such a video information correctly from FFprobeKit.getMediaInformation().

@SandipJawaleRN Hello sir , how did you fix this , I' having the same issue , the video duration is 4m52s , but FFprobeKit.getMediaInformation(inputURL.path).getDuration() returns 13 which is "unrelated" 😂

Edit: I know now , it's not the video duration , but the time taken to execute of session Now , how can I get the video total duration ?

Edit2 : finally I figured out it prints 291.860000 ( 4.86 m = 4m52s) Anyway I still want to know if there is a better way to get the video duration

FFprobeKit.getMediaInformation(fromCommandAsync: "-i \(inputURL.path) -show_entries format=duration -v quiet -of csv='p=0'", withCompleteCallback: { mediaInformationSession in

                        }, withLogCallback: { log in
                            if let msg = log?.getMessage() {
                                print("----------")
                                print(msg)
                                print("----------")
                            }

                        }, onDispatchQueue: DispatchQueue.main, withTimeout: 10000)
