This question puzzled me for some time, how to somehow read the length of the video without downloading the entire file.

Doing some tests with the pymediainfo library, came up with this:

def main():


    auth = JWTAuth.from_settings_file('.jwt.config.json')


    auth.authenticate_instance()


    client = Client(auth)





    user = client.user(user_rb_id).get()


    print(f"User: {user.id}:{user.name}")





    user_client = client.as_user(user)








    folder = user_client.folder(video_folder_id).get()


    print(f"Folder: {folder.id}:{folder.name}")





    items = folder.get_items()


    for item in items:


        print(f"Item: {item.id}:{item.name}:{item.type}")


        if item.type != 'file':


            continue





        item_url = item.get_download_url()


        # print(f"URL {item_url}")





        tic_download = time.perf_counter()


        media_info = MediaInfo.parse(item_url)


        print(f"MediaInfo w/ URL time: {time.perf_counter() - tic_download} seconds")





        tic_download = time.perf_counter()





        with open('./tmp/tpm_'+item.name, 'wb') as tmp_file:


            item.download_to(tmp_file)





        media_info = MediaInfo.parse('./tmp/tpm_'+item.name)


        print(f"MediaInfo w/ download time: {time.perf_counter() - tic_download} seconds")

With the following results:

Folder: 191494027812:Video Samples


Item: 1121082178302:BigBuckBunny.mp4:file


MediaInfo w/ URL time: 3.798498541000299 seconds


MediaInfo w/ download time: 21.247453375020996 seconds


Done

Looking at the time it takes to run the MediaInfo.parse() , it seems it doesn’t need to download the entire file.
