Functions

reencode_videos(sample_collection[, …])

Re-encodes the videos in the sample collection as MP4s that can be visualized in the FiftyOne App.

fiftyone.utils.video.reencode_videos(sample_collection, delete_originals=False, ext='.mp4', verbose=False, **kwargs)

Re-encodes the videos in the sample collection as MP4s that can be visualized in the FiftyOne App.

The filepath of the samples are updated to point to the re-encoded videos.

You can configure parameters of the re-encoding such as codec, compression, resolution, and frame rate by passing keyword arguments for eta.core.video.FFmpeg(**kwargs) to this function.

By default, the re-encoding is performed via the following ffmpeg command:

ffmpeg \
    -loglevel error -vsync 0 -i $INPUT_PATH \
    -c:v libx264 -preset medium -crf 23 -pix_fmt yuv420p -vsync 0 -an \
    $OUTPUT_PATH

Parameters

• sample_collection – a fiftyone.core.collections.SampleCollection

• delete_originals (False) – whether to delete the original videos after re-encoding

• ext (".mp4") – the video container format to use

• verbose (False) – whether to log the ffmpeg commands that are executed

• **kwargs – keyword arguments for eta.core.video.FFmpeg(**kwargs)
