When using MediaFoundation API to play a HAP video, the video proportion is displayed incorrectly

Open moontains opened this issue 1 year ago • 6 comments

When using MediaFoundation API to play a video, the video proportion is displayed incorrectly

Your Setup (please complete the following information):

  • Unity version: Unity: v2019.4.26f1c1 WindowsEditor

  • AVPro Video version (number and edition (trial/core/ultra/enterprise)): v2.6.6 (plugin v2.6.3f1-ultra)

  • Operating system version: Windows 10 (10.0.22621) 64bit

  • Device model:

  • Video specs (resolution, frame-rate, codec, file size): 128*128 ；25；Hap Alpha mov ；1M

To Reproduce

  1. The same video is played on UGUI, and Scale Mode uses Scale To Fit.
  2. When using DirectShow Api to play, the screen ratio is displayed normally; when using MediaFoundation Api to play, the screen ratio is displayed incorrectly.
  3. In the WindowsMediaPlayer - GetTexturePixelAspectRatio method, the two APIs have different return values, which may be the key to this problem.

Well, I tested the same video on the latest version and the problem persists. Could there be something wrong with my video?

Any luck?

I had a look into why the Custom MOV Parser was returning incorrect video aspects and found it was using a pixel aspect ratio (PAR) of 2 by default, instead of 1.

Fixed for the next release.
