I WOULD LOVE IT IF SOMEONE SMARTER THAN ME CAN PROVE ME WRONG.
I'm the one who started this topic and never mentioned Youtube.
CreativeLive and Kelby training are places with training programs in mp3/mp4 format which you can download after you pay for them.
From these sites you could download the streaming video using an app like the (now banned by Apple) Video D/L Lite by publisher George Young, or the My Media app ( also banned by Apple this year), and listen to them from the lock screen. (just the audio).
I guess I am different to the typical Apple user who gets fat on tv shows and movies in that I like to do actual work with my equipment.
Apple BANNED these so that Apples NATIVE MUSIC APP has no COMPETITION. It's like Microsoft with the IE issue that got brought infront of the Antitrust commision on unfair business practices and they had to pay billions in fines.
IF you have an app that features these two functionalities (1. play audio from downloaded video in background, i.e. from lockscreen 2. has a repeat function) try to backup your iphone and then reset and restore it. You will find the app has mysteriously disappeared among the "some items couldn't be restored" list and disappeared off all your purchased app lists.
Apps like Onlineplayer or IDM Loader were not banned because they can download video but stop playing the audio as soon as you lock your phone, so you waste battery by having the screen on. Apps like Video D/L were banned in 2013 for having a repeat function. MyMedia was banned this year because it DID allow the audio to be played when the lock button was pressed. All these bans to force people to use the native Apple music app.
I Would LOVE to be proven WRONG and be shown a video/file downloader app that can play audio from lock screen and has a repeat button.
I WOULD LOVE IT IF SOMEONE SMARTER THAN ME CAN PROVE ME WRONG.
