video_encoding.encoding package¶

Submodules¶

video_encoding.encoding.local module¶

Create temporary directory.

Returns: Tempfile object.
Return type: tempfile.TemporaryDirectory

video_encoding.encoding.utils module¶

video_encoding.encoding.utils.clean_up(path)[source]¶

Remove the folder

Parameters: path (str) – Path or folder to remove.

video_encoding.encoding.utils.get_file_name_extension(path)[source]¶

Get the file name and extension from the path.

Parameters: path (str) – Path of the file.
Returns: Tuple of file name and file extension.
Return type: Tuple(str, str)

video_encoding.encoding.video_encoding module¶

class video_encoding.encoding.video_encoding.Process(in_path, resolution, out_path)[source]¶

Bases: object

convert(video, writer, width, height)[source]¶

Convert the video frame by frame into the provided resolution frame by frame.

# TODO: Make this function parallel.

Parameters

video (cv2.VideoCapture) – Video that is to be encoded into a given resolution.
writer (cv2.VideoWriter) – Video writer which writes the encoded video frame by frame.
width (int) – Width according to the resolution to be set for the video.
height (int) – Height according to the resolution to be set for the video.

Return type

None

encode_audio(temp_video_path)[source]¶

Encode the audio into resized video.

Parameters: temp_video_path (str) – Temporary file path where the resized video is stored.
Returns: Final resized video to choosen resolution.
Return type: VideoFileClip

property encode_video¶: Encode the video and perform the process of conversion of and saving the video.

extract_audio()[source]¶

Extract audio from video.

Returns: Audio extracted from the video.
Return type: AudioFileClip

get_height_width_res()[source]¶

Get the height and width for a given resolution.

Returns: Height and width for a given resolution.
Return type: namedtuple

writer_setup(temp_path, fps, codec, width, height)[source]¶

Video writer setup according to the original frame per second, codec, width and height.

Here it is ensured that we preseve the original codec and frames per second (fps) of the original video. Hence the fps and the codec are extracted from the video information before the conversion of the video.

Parameters

temp_path (str) – Temporary path where encoded video is stored.
fps (float) – Frame per second of the original video before encoding. This is to preserve the fps from the original video.
codec (str) – Video coded to be used. This is determined by the extension currently.
width (int) – Width to set according to the resolution.
height (int) – Height to set according to the resolution.

Returns

OpenCV video writer object with the settings from the original video.

Return type

cv2.VideoWriter

video_encoding.encoding.video_information module¶

Function or utilities to get more information about the video. These includes functions to get video properties like:

Frame Rate

Video Height

Video Width

Total number of frames

video_encoding.encoding.video_information.Video_information[source]¶: alias of video_encoding.encoding.video_information.VideoInfo

video_encoding.encoding.video_information.get_video_information(video)[source]¶

Collect and present information about the video.

This function get the following information about a video. * Frame Rate * Width of the video. * Height of the video. * Total frames in a video.

Parameters: video (cv2.VideoCapture) – Video for which the information is required.
Returns: Frame rate, width, height and total frames in a video.
Return type: Video_information
