What has changed and why?
Fix frame orientation issue.
We use two libraries to load videos:
However, OpenCV does not read video metadata properly and can return frames in wrong orientation
Solution
During indexing, use PyAV to get frame orientation. Note that PyAV only makes this metadata available on the frame level, not on the video level.
Considered options
ffmpeg-pythonexposesffmpeg.probe()function that returns the metadata. However, it callsffmpegin a subprocess and thus is not suitable for use with cloud storage.How has it been tested?
Loaded a video dataset that was previously displayed wrong.
Did you update CHANGELOG.md?
