Dolby Vision with HDR fallback has incorrectly sized enhancement layer #5783

Open ChrisRosser opened 4 months ago

ChrisRosser commented 4 months ago

Describe The Bug When Playing Dolby Vision content with HDR10 fallback with a non-standard aspect ratio the enhancement layer is incorrectly sized over the base layer. It looks like the black bars top and bottom are exactly double the width on the enhancement layer (maybe some offset being applied twice?)

Steps To Reproduce

Play Dolby Vision content with HDR10 fallback.

Expected Behavior Enhancement layer should perfectly match the underlying base layer.

I can confirm the issue is present with prefer fMP4 enabled and disabled. This setting doesn't appear to make any difference to this particular problem. The key issue appears to be aspect ratio.

File that works perfectly: Codec: HEVC AVC: No Profile: Main 10 Level: 150 Resolution: 3840x2160 Aspect ratio: 16:9 Anamorphic: No Interlaced: No Framerate: 24 Bitrate: 18942 kbps Bit depth: 10 bit Video range: HDR Video range type: DOVIWithHDR10 DV title: DV Profile 8.1 (HDR10) DV version major: 1 DV version minor: 0 DV profile: 8 DV level: 6 DV rpu preset flag: 1 DV el preset flag: 0 DV bl preset flag: 1 DV bl signal compatibility id: 1 Colour space: bt2020nc Colour transfer: smpte2084 Colour primaries: bt2020 Pixel format: yuv420p10le Ref frames: 1

Problem file: Codec: HEVC AVC: No Profile: Main 10 Level: 153 Resolution: 3840x1608 Aspect ratio: 2.40:1 <<<<<< This is the only real difference between these two files.
