Bug ID: 521234
Summary: Transcoding of VFR clips loses orientation (regression
from 26.04.1 to 26.04.2?)
Classification: Applications
Product: kdenlive
Version First 26.04.2
Reported In:
Platform: Flatpak
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Project Bin & Import
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
DESCRIPTION
I have video clips with the following orientation information:
```
$ ffprobe -v quiet -print_format json -show_streams 'video.mp4' | grep side -A
20
"side_data_list": [
{
"side_data_type": "Display Matrix",
"displaymatrix": "\n00000000: 0 65536
0\n00000001: -65536 0 0\n00000002: 0
0 1073741824\n",
"rotation": -90
}
]
As they are VFR, when I add them, Kdenlive offers to transcode them in order to
work with them.
As soon as it's done transcording, however, the orientation of the clip changes
from vertical to horizontal.
This appears to be a regression, as it wasn't happening before the upgrade to
26.04.2; I've now downgraded to 26.04.1, and I've reproduced the prior,
seemingly correct, behavior.
STEPS TO REPRODUCE
1. Drag a VFR clip with rotation information as above into the project bin
2. Accept the offer to transcode
3. Wait until finished
OBSERVED RESULT
The clip is in the wrong (horizontal, in my case) orientation.
EXPECTED RESULT
The orientation of the clip should remain as originally shown before
transcoding.
SOFTWARE/OS VERSIONS
Operating System: Fedora 43
KDE Plasma Version, KDE Frameworks Version, Qt Version: unsure how to obtain,
I'm running the Flathub flatpak from GNOME
