My goal is to download a specific stream of video from neulion. The two hour video is split into thousands of mp4 slices. The url naming scheme does not have a progressive numbering logic (is not: ...1.mp4, ...2.mp4, ...3.mp4). Instead it has three variables:
general structure: http://...2013_h_whole_1_*.mp4/*/*.mp4
I broke the process into three stages:
1. Capture all the urls (using Coojah)
2. Download the video slices from the captured url (using wget)
3. Re-join the slices into a single mp4 file (using mp4box)
Stage 1: I played the video and used Coojah to capture the urls and their streaming order (thanks to rubiohiguey for Coojah and a good deal of other info! - see below)
Stage 2: I downloaded the files using wget, a simple script and the url list from Stage 1 (I could have used Coojah here too, but decided it was more transparent to me if I used wget + simple script)
Stage 3: I re-joined the mp4s downloaded in stage 2 using MP4Box, a simple script and the url list (to provide me the correct file order)
The result was a single video, with moments of clarity, but in general a mess. Often it looked like images were overlapping and colors were sometimes off. The limits of my knowledge prior to this was very straight-forward downloading with no complexities.
Am I missing something obvious?
Is using wget or mp4box inappropriate?
rubiohiguey mentioned using ffmpeg - should I be using that instead of mp4box?
unfortunately, I cannot provide a link to the video
