The contribution YouTube Meets Creative Commons, I wanted to finally upload a short video on YouTube with recordMyDesktop created. This is a problem I noticed again that I had ever been associated with open shot. The uploaded video is not displayed correctly, instead, you only see a green box. This is probably also again a missing keyframe at the beginning of the video.Totem and Co. do not mind. OpenShot or even YouTube are refusing to accept the video.

YouTube expressed the problem with a “green video” which you can see, unfortunately, only after the final conversion from YouTube. YouTube itself does not show any error in this regard.

Been tracked down by my solutions to this problem is limited to the recoding of the recorded video. Perfect I think this workaround may not, but as long as recordMyDesktop not understand, and YouTube, it is probably a necessity.

Coding can happen with either mencoder or ffmpeg, ffmpeg which may seem to be the smarter solution, since it thanks to the option “sameq” automatically checking tried a similar quality as the video input to achieve.

$ Mencoder-o out.ogv out.avi-oac mp3lame-ovc lavc$ Ffmpeg-i-vcodec mpeg4-acodec out.ogv libfaac-sameq out.mp4

The result can then easily upload to YouTube and of course to be finished with the open shot. Should you frequently work with screencasts, so you can make your lives a little easier and grab the command including a few dialogues in the script for Nautilus, so that you can transcode from Nautilus out a recording.

Created

To the folder ~ / .gnome2/nautilus-scripts your script. You can choose any name, but he appeared later on also in Nautilus, so I would use a meaningful name, so … For example,

$ Gedit “~ .gnome2/nautilus-scripts/Screencast / prepare for YouTube”Adds

Unchanged then the file in the following content. In the Sktip Zenity is used around the filename of the converted file to query and display a progress bar …

123# / Bin / bashconvers = $ (zenity – entry – text = “Please enter the name that is said to have converted the movie, please file extension”)kod = `mencoder-o $ $ NAUTILUS_SCRIPT_SELECTED_FILE_PATHS convers-oac mp3lame-ovc lavc '| zenity – progress – text =” Progress … “- percentage = 0 – pulsate# / Bin / bashconvers = $kod = `mencoder-o $ $ NAUTILUS_SCRIPT_SELECTED_FILE_PATHS convers-oac mp3lame-ovc lavc '| zenity – progress – text =” Progress … ” – Percentage = 0 – pulsateIf you want to use ffmpeg instead

Mencoder, which must change the script accordingly. Finally, the script must be made more feasible. If your seiht already in a terminal, you can also do the same there …

$ Chmod + x “~ .gnome2/nautilus-scripts/Screencast / prepare for YouTube”Now you can

With the right mouse button click on an image of the desktop recorder and call the script from the menu. After entering the file names for the file to be created, and begins to count mencoder to convert the video.

[UPDATE 21/06/2011] Tom has advised me on it, that the installation of ffmpeg alone is not enough. It still needs a special version of the package libavcodec-extra-52 from the Medibuntu sources. Without this package, you only get the error message Unknown encoder 'libfaac' to see. Therefore, these sources with an Ubuntu installation be added later by hand.

$ Sudo wget http://www.medibuntu.org/sources.list.d/ `lsb_release-cs` list -. Output-document = / etc / apt / sources.list.d / medibuntu.list & & sudo apt-get-q update & & sudo apt-get – yes-q – allow-unauthenticated install medibuntu-keyring & & sudo apt-get-q update$ Sudo apt-get install ffmpeg libavcodec-extra-52

… then it should work with ffmpeg.
