I have previously experienced no problems when I have downloaded videos from YouTube using Real Downloader and then viewing them in VLC media player. However, I have recently been experiencing problems in that while the videos still appear to download okay, they no longer play in VLC media player. (I have no sound or video although VLC shows the title and duration of the downloaded video.)
Old videos which I had downloaded earlier using Real Downloader from YouTube still play perfectly okay in VLC media player. It is only new videos that no longer play. I have tried various titles but none of them play. Have YouTube changed their video coding recently to prevent videos downloaded from playing? I would point out that I have little technical knowledge.
I would appreciate any help that anyone can give me.
Hello all, I have managed to solve the problem myself.
This is the solution that worked for me:
After trawling the web and other forums, I have found a downloader that still plays You Tube music videos (even Vevo ones). It is the YouTube Video and Audio downloader (version 0.2.2) which is an Add-On for Firefox and plays them in the .flv format. it can be found here.
The version of Real Downloader is 22.214.171.124. The version of VLC Player is 2.0.7. Twoflower. Both were installed within the last two weeks so should be the latest versions. I find that I am unable to play any music videos on YouTube. I provide a link to one of them https://www.youtube.com/watch?v=GZfj2Ir3GgQ I also provide a link to the debug file of another video which I pasted on https://pastebin.com/w9fuFafh
From searching other forums it seems that the problems I am experiencing are widespread and have something to do with YouTube having made some changes to their website and the DASH format....whatever that is?
I still have no downloading button appearing with Firefox. It is present with IE9 but downloaded videos do not play.
Thanks Jack for your help, but I know that Real Downloader is up-to-date as I only downloaded and installed it on 15 June 2013 after having taken my pc back to factory settings. I believe my problem is related to the video files downloaded from YouTube not being able to be read by VLC Media Player, rather than a problem with Real Downloader itself.
"We are aware of a compatibility issue that is preventing some .mp4 files from playing in RealPlayer. Essentially, the files that are being downloaded are not actually MP4s but a new streaming format that is being misidentified as MP4.
I would appreciate anyone's help in regard to my post of 23 June.
Since I last posted I have found that the Real Downloader "Download this video" button has disappeared from Firefox. (I suspect this may have something to do with me installing the latest Java update [Version 7 Update 25]). I also lost the button temporarily in IE9 but it reappeared after I disabled the Java(tm) SSV Helper. Downloaded music videos still fail to play (although a couple of news videos have downloaded sucessfully which play okay). However, the majority of content on YouTube still will not play after downloading with Real Downloader.
Does anyone how know I can fix Firefox and The YouTube problem?
Thanks once again for your help Jack it is appreciated. I checked that the Real Downloader Add-On was enabled. There was no compatibility issue.
I also followed the instructions given in the Real link you supplied but I am afraid that disabling Adobe MMS.cfg did not work either. The Real Downloader "Download this video" button still does not appear in Firefox.
The file extension of the videos I am unable to play in VLC Media Player are MP4s.
Thanks Jack for the suggestion, but I think I will stick to Firefox 22, rather than revert back to an earlier version. The reason is that I also use IE9 which does show the Real Downloader button. However, when I download music videos from YouTube they still do not play. So, I do not feel it is worthwhile going back to Firefox 22 just to get the Real Downloader button working as I do not believe the videos will play.
I have tried playing music videos downloaded with Real Downloader using IE9 in Windows Media Player but they do not play in that format either. I have not installed Media Player Classic. I might look into that, but I fear that they would not play in that player either.
Thanks. I think I understand what you are saying now. When you were referring of the need to install codecs for video players, you were referring to other players which currently do not have the necessary codecs to play music videos downloaded from YouTube - not VLC player.
Thanks once again Jack. My version of Firefox is 22.0 and it is up-to-date. I take your point about YouTube changing its streaming, which I believe they have done. However, would that effect all their videos, including those posted before YouTube updated?
Thanks Jack for the reply. I have tried again to play the video in Windows Media Player, but I am afraid it does not play for me (no audio or video). It identifies it as a mp4 file but I then get a message that the codec is not supported.
Hi, I had the same problem, what I did was I installed klite codec pack and select all extensions for video and audio during installation and after installing the codecs, open your file in media player classic home. chances are it will work.
