I would like to easily be able to convert a MKV video to MP4 video in Ubuntu. Is there any way I can easily do this at all?
I can't play or stream online videos with MKV extesions in Firefox though I can play these videos through Chrome. It says "The media could not be loaded, either because the server or network failed or because the format is not supported." while trying to play the video.
I am Using the latest Firefox for Ubuntu 16.04
Just downloaded a big mkv file which is more than 20GB. It took me several days to finish the downloading. But, how to check whether the download has been completed, or it was just aborted halfway? I have this question, because for a mkv file, mplayer can still play it until the point it is broken.
Any utility in ubuntu for such kind of checks?
I have an opera that I'm ripping to my computer in MKV format with Handbrake. This opera is on two discs. Is there a way to join the resulting MKV's together? They will have the same bitrate, resolution, etc. If I do this, can I keep chapters from both MKV files organized? And, since I have subtitles in the file (not burnt in), will they still stay intact?
I'm not too sure if this question is off-topic or not. If it is, feel more than free to delete it. :)
I'm quite new to multimedia things, I'm trying to find a way to make nice screencasts, I've already been able to capture my desktop with ffmpeg:
$ ffmpeg -f alsa -ac 2 -i hw:0,0 -f x11grab -r 30 -s $(xwininfo -root | grep 'geometry' | awk '{print $2;}') -i :0.0 -acodec pcm_s16le -vcodec libx264 -vpre lossless_ultrafast -threads 0 -y out.mkv
It works pretty nice, but I'd like to add music in the background, if I add it with mencoder:
mencoder -ovc copy -oac mix -audiofile track.mp3 out.mkv -o out.mp4
It delete the video sound, I don't want to replace it, I want to add music to my explanation, any ideas?
