codenoobforreal · 2021-11-26T08:19:40Z

Steps to Reproduce

flutter create bug
add the video_player plugin
Run the code sample

Expected results:
the same size on iOS and android

Actual results:
height is correct but width is wrong

iOS

flutter: ======== Size(782.8, 1080.0)

android

[+1825 ms] I/flutter ( 5846): ======== Size(1696.0, 1080.0)

Code sample

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  // This widget is the root of your application.

        // changing the primarySwatch below to Colors.green and then invoke
        // "hot reload" (press "r" in the console where you ran "flutter run",
        // or simply save your changes to "hot reload" in a Flutter IDE).
        // Notice that the counter didn't reset back to zero; the application
        // is not restarted.
        primarySwatch: Colors.blue,

Hi @codenoobforreal, thanks for filing the issue.

Please provide a sample video for reproduction. Also, please specify which version of video_player you're using.

Thank you

codenoobforreal · 2021-12-01T11:22:14Z

hi @danagbemava-nc,nice to hear that.I am using video_player: ^2.2.5.
video below.

Hi @codenoobforreal , one more question, is this issue on android or iOS?

Please provide the output of flutter run -v as well.

The output is likely to be huge, so please put it into a .txt file and attach it here.

Thank you

Probably related to #51250

I did a bit digging into the video_player source and I noticed the size is created at this point

size initialization in plugin

https://github.com/flutter/plugins/blob/702fada379f3b7b70a0b3af9879aa0629a1533b6/packages/video_player/video_player_platform_interface/lib/method_channel_video_player.dart#L108

 return VideoEvent(
            eventType: VideoEventType.initialized,
            duration: Duration(milliseconds: map['duration']),
            size: Size(map['width']?.toDouble() ?? 0.0,
                map['height']?.toDouble() ?? 0.0),
          );

and these values are from exoplayer on the native side

width and height from native side

https://github.com/flutter/plugins/blob/702fada379f3b7b70a0b3af9879aa0629a1533b6/packages/video_player/video_player/android/src/main/java/io/flutter/plugins/videoplayer/VideoPlayer.java#L274

if (exoPlayer.getVideoFormat() != null) {
        Format videoFormat = exoPlayer.getVideoFormat();
        int width = videoFormat.width;
        int height = videoFormat.height;
        int rotationDegrees = videoFormat.rotationDegrees;
        // Switch the width/height if video was taken in portrait mode
        if (rotationDegrees == 90 || rotationDegrees == 270) {
          width = exoPlayer.getVideoFormat().height;
          height = exoPlayer.getVideoFormat().width;
        }
        event.put("width", width);
        event.put("height", height);
      }

If you look at the logs, you'll notice this somewhere in there

codec information

[        ] D/CCodec  ( 5846): } and output: AMessage(what = 0x00000000) = {
[        ] D/CCodec  ( 5846):   int32_t android._color-format = 2135033992
[        ] D/CCodec  ( 5846):   int32_t android._video-scaling = 1

[        ] D/CCodec  ( 5846):   int32_t color-range = 2
[        ] D/CCodec  ( 5846):   int32_t color-transfer = 3
[        ] D/CCodec  ( 5846):   int32_t height = 1080
[        ] D/CCodec  ( 5846):   int32_t max-height = 1080
[        ] D/CCodec  ( 5846):   int32_t max-width = 1696
[        ] D/CCodec  ( 5846):   string mime = "video/raw"
[        ] D/CCodec  ( 5846):   int32_t rotation-degrees = 0
[        ] D/CCodec  ( 5846):   int32_t sar-height = 1
[        ] D/CCodec  ( 5846):   int32_t sar-width = 1
[        ] D/CCodec  ( 5846):   int32_t width = 1696
[        ] D/CCodec  ( 5846):   int32_t android._dataspace = 260
[        ] D/CCodec  ( 5846):   int32_t color-format = 2130708361
[        ] D/CCodec  ( 5846): }

which is coming from exoplayer, you'll notice that the width is reported as 1696 which matches what you got. So I decided to look into it further to see if anyone had reported this to exoplayer and I found this GH thread google/ExoPlayer#3690, so I decided to try what was stated in google/ExoPlayer#3690 (comment) with a native android application.

D/test: height: 1080
D/test: width: 1696
D/test: pixelWidthHeightRatio: 0.46153846
    width * pixelWidthHeightRatio: 782.7692

The value is closer to what expected it to be. It looks like the pixelWidthHeightRatio is not being taken into account when retrieving the width and height. I don't know why that is the case, labelling for further insight.

I found that the width and height of the video are only obtained once during initialization, but this does not meet my expectations. If it is a live broadcast and the width and height of the video will change, there will be a problem with the aspect ratio at this time. I hope his width High is real time.
