WebM Video Codec in Skype 5.0 Group Video
9 novembre 2010, par noreply@blogger.com (John Luther)Our friends at Skype recently released Skype 5.0 for Windows and Mac, which features a beta group video feature using VP8, the video codec in WebM. In the first half of 2010, approximately 40% of Skype-to-Skype calls were video calls and we’re excited that in the future many of those calls will be made using VP8.
To check out the new group video feature, simply download the Skype Software.
Note : For group video to work, everyone on the call needs the new Skype for Windows or Mac, a webcam and a broadband connection.
For more info about Skype group video, visit the Skype website.

Converting mkv to h264 FFmpeg
14 janvier 2021, par Rikus HoneyEDIT :
This question has become very popular and is one of the top results for searching "convert mkv to h264 ffmpeg" and thus I feel it is appropriate to add that for anyone stumbling upon this question to rather use


ffmpeg -i input.mkv -c:v libx264 -c:a aac output.mp4



as
libvo_aacenc
has been removed in recent versions of FFmpeg and it now has a native aac encoder. For more information visit the FFmpeg wiki page for encoding AAC.

Here is the original question :


I would like to convert my .mkv files to .mp4 using FFmpeg. I have tried the following code :


ffmpeg -i input.mkv -c:v libx264 -c:a libvo_aacenc output.mp4



But I get the error :




Error while opening encoder for output stream #0:1 - maybe incorrect parameters such as bit_rate, rate, width or height.




Is there any way to get around this ? I have tried setting the bitrate of the audio but the problem seems to persist.
