ffmpeg.exe by itself will not do anything. That's why you're seeing a black window pop open and then close. It's an executable that needs arguments. You can see a listing of all the arguments it can deal with by opening a command window, navigate to a folder containing ffmpeg.exe, and type ffmpeg --help at the command prompt. It'll race by, so you could use the |more pipe (eg. ffmpeg --help|more) or just scroll back up to the command to read from the top.

I find the easiest way to deal with this kind of command line executable is to write a batch file, especially when dealing with lots of text like some of the URLs we have to deal with.

Do to this, I create a new text file with a line of text starting with the letters rem (remark) with a comment about the use of the file - usually just the subject of the video to be processed. On the next line I type in the ffmpeg command line that I wish to process. You don't have to, but I often put a last line in the file with the pause command so I can see any feedback in the command window before it closes. Then I save it as a batch file (eg. file.bat) and place it in the same folder as ffmpeg.exe. Make sure you have room for the new video file there, or else add a path to the output filename (spaces require that the output name is surrounded in quotes) where you know there's enough free space.

rem - 2012 Olympics Track & Field Men's 100 Meter Final
ffmpeg.exe -i "http://www.youtube.com/api/manifest/hls_playlist/id/.../key/ck1/file/index.m3u8" -c copy newvideo.ts
pause

Once you've got a batch file in the folder you've chose for ffmpeg and the video, you will not need to use the command prompt window. Just double-click on the batch file.

Does that make sense?

thanks, it remains difficult to understand for me because i don't have a "great" experience in this :/ but for example in this video http://www.youtube.com/watch?v=78btYWiv_xM where is the ..api/manifest....? how can i take this link? i'm sorry, i'm a disaster!! maybe the best solution is someone who download video for me and then upload on a file sharging site

The URL for such programs often have an expiration date and they can be machine specific. I've found that to be the case with all the NBCOlympics videos that are served in 5-second chunks.

You won't be able to download/transcode (that's pretty much what ffmpeg is doing) the video without the proper URL, but there are numerous tools to do this. It's not completely trivial, as sometimes you have refresh the page and/or restart the video in order for the URL to be detected, but for these Olympics videos you're looking for the URL that ends in .m3u8. There are many ways to grab that URL. I happen to use the web console in Firefox (ctrl-shift-k) and enter m3u8 in the filter box in the upper right corner. The URL generally pops up right at the beginning of the video and that's all you need.

Don't give up - you're about to get this and then you'll be helping others.

thanks for all your help and patience, i'm looking for the m3u8

I usually take the last one, as it's the one that pops up the moment I click on the 1080p HD option of the quality gear in the video.
