Hey @sgunhouse and @leocg ,
I faced the same issue, and after some experiments I found out that videos with more than 1090 (1092) height aren't playing in Opera, but with 1088 height they're playing fine for me.
I tested with same file encoded:
Encoding settings for 1088:
When opened in opera, video and audio work fine.
What Media Internals says:
But when encoded with 1092 height, video doesn't work in Opera, just audio:
Encoding settings for 1092:
Everything is the same, just different height.
What Media Internals says:
found_video_stream false
Uploaded both files here
https://drive.google.com/drive/folders/12-ZBIRLCwumCbnoAkrR8X2omDUjOyZP5?usp=sharing
Opera Version: 62.0.3331.116 and 63.0.3368.66
OS: Windows 7 64-bit
Video card: Nvidia GeForce GTX 1070 with 382.33 driver
Bug exists in incognito mode (no extensions), and on different monitors (1080p, 1440p)
So it's not about codec/specific website, but about height of each particular video.
Also, in Chrome any height works fine for me.
Can you please confirm this bug?
Thanks!
