FFMpeg && pyFFMpeg - have questions!

Question

linux

Good night,% habrauser%

There is a task, a mini-task, the answer to which I do not want to know here. But I want to know the ways and methods of solving, and all kinds of manuals.

What you need:

There is a folder with a movie. You need to enter it, read what is in it (obviously there is only video), and write what you read to a file.

Plan:

Go to the folder, make a listing, write the list to a file (so that the movie names are with the extension, and if possible the relative path is "~/home/movie/" ). Go to the file, and in turn call the file from the list to be processed by ffmpeg to extract the length of the video.

PS: why not use ffmpeg -i ./movie.flv | grep length? Because the interest is to make a mini ffmpeg wrapper

I don't want to know the answer, I want to come to it myself. However, I want to get parting words or some examples. Let's say entering a folder, parsing a folder, writing a listing to a file.

Thanks\thx!

Answer 1

For a list of files in a directory, see docs.python.org/library/os.html#os.walk For
help using pyffmpeg, google it. Also remember pymedia.org/ (another ffmpeg wrapper). As an option, call ffmpeg and take data from its output.

Answer 2

Use mediainfo, the output of the necessary parameters is configurable, it can be used in shell scripts without additional processing
