[BUG] Cannot play an incomplete download MKV file with HEVC stream

[h0tk3y]

Describe the bug Upon an attempt to open an MKV file that is still being downloaded, Next Player shows an error and fails to play the file.

The MX Player and the built-in Samsung Gallery / Video players manage to play the downloaded prefix of the file.

The media information of the file as shown in the properties dialog from the Next Player's file browser:

To Reproduce Steps to reproduce the behavior:

1. Start downloading a large file sequentially
2. While the download is incomplete but a big part of the file is downloaded, try to open the file in Next Player either via the in-app file browser or in a file manager app

Expected behavior The start of the file is played, until the incomplete part is encountered.

Device info (please complete the following information):

• Device: Galaxy S24 Ultra
• Android version: 14
• App version: 0.12.3

I can look for more specific logs if pointed to what to look for, like a tag to filter the logcat.
