While the WebM file plays fine I get prompted to download the MP4 file because “Tor Browser cannot display this file”.
YouTube is working using HTML5.
I noticed that the Tor Browser doesn’t have the OpenH264 plugin maybe that is the reason?
For testing purposes I tried installing the OpenH264 plugin or getting it to download by setting “media.gmp-provider.enabled” to true in about:config but it would only say that the plugin will be installed shortly. I don’t remember the exact wording sorry.
Does someone else have this problem if it even is one?
first of all, en- and deenabling featuers like this will not really benefit you, as your fingerprint is even easier to “pin point” when you make it a habit to fluctuate the configuration in a predictable way. It might actually make it (even) easier to track you, then keeping the feature enabled all the time. Furthermore, what issue are you currently facing then?
I understand. What if I made two different workstations one has the feature enabled and the other disabled and I only use the one that has it enabled to browse websites that need it. One of those websites would be Vimeo as far as I know.
Also using the search function in about:config to search for the features I need to enable doesn’t bring up any results.
For me, the hardest part of troubleshooting is figuring out whether something is a Qubes / Xen / Whonix / Debian / KDE / VirtualBox / Tor / Tor Browser / Firefox issue! Ego did the hard part, easy part - search “play mp4 iceweasel”.
WARNING: Iceweasel is unmodified by Whonix, meaning you have to harden it yourself and configure privacy settings / addons yourself. You may just want to use with default settings + workaround in link to reduce fingerprint? In this case, definitely use a dedicated + disposable/amnesic VM for this purpose. IP will not be de-anonymized - thanks to Whonix - but should assume you will be pseudonymous (unique fingerprint).
Safest to download videos with TBB as Ego said, then play on un-networked disposable VM.
Sorry man, it seems that you know quite a lot about video playback issue. I have a question about it and would you mind me asking here? The thing is that recently I downloaded a YouTube MP4 video at this site as you can see " http://www.videoconverterfactory.com/tips/vdgb-yt-downloader.html"(I hope someone else if at convenience can check it), the videograbby. I move the MP4 video to my Windows Media Player. However, to my disappointment, there was only video output no audio, but after I converted the video to regular AVI video, then it was okay. why did this shit happen? Was that because of t he downloader itself or any codec errors?
