Difficulty playing (decoding?) MP4 download
I've downloaded an MP4 of a Youtube purchase and cannot get it to play on Windows Media Player, Quicktime or Real Player. It was downloaded with FlashGot, the program I had previously installed in Firefox, and has appeared as four MP4 files, one of which has an "▶_" before it.
I think I need to decode it somehow, but have never done so and am not sure how to begin (if that's the problem). Any help would be greatly appreciated. Thanks :) |
Try VLC or mpc
|
Thanks, I tried VLC but no luck.
I'm really hoping an editing program will open the file and allow me to write a fresh MP4. I'd like to avoid strings altogether, even if it results in a bit of loss if re-encoding is needed. Hopefully it wouldn't be. |
I looked at the details via MediaInfo and came up with the following for each of the four resulting file downloads. Can anyone help? It looks to me like they need to be decrypted.

If you can't get it to play, I don't believe its possible to remove youtube DRM. I believe it stores license info server-side, so playback can only take place online. |
I didn't even know Youtube sold anything. :laugh:
The only way to record some videos is with a really, really good video card in a high-RAM system, a good online connection, and use screen cap software. I've done this a few times on my Mac (16gb RAM), using Hyper Cam 3 in Parallels. The screen cap program are easily susceptible to lags and graphics tearing (not to be confused with video tearing). |
