comment when run a ffmpeg system will shutdown after sometime
That does not rule out overheating which a few users have claimed to experience when performing CPU intensive commands of longer durations.

comment when run a ffmpeg system will shutdown after sometime
There is very little information here to provide much help. Are you using a laptop? Is it overheating? Video encoding is very CPU intensive.

comment ffmpeg: installing from repository or compiling from source?
@Dan Then I assume it failed during configure (possibly due to previous failure of compilation of any required external library) or make, but it is only a guess without any actual error messages.

Unfortunately that is not the complete console output. You can, of course, omit multiple repeating lines.

comment Incorrect duration time in Audacious or any musical player when convert with ffmpeg or avconv
Glad it worked. You can provide and accept a full answer to your own question so others know a solution was found. I don't recommend /use/bin/ for your binary. You can put it in /usr/local/bin/ instead (or elsewhere in your PATH) and then you can keep the fake "ffmpeg" package for other dependent packages.

comment Incorrect duration time in Audacious or any musical player when convert with ffmpeg or avconv
Instead of providing ffmpeg from FFmpeg, Ubuntu uses a fork that supplies avconv and a fake "ffmpeg" which are often buggy. What happens if you download a recent build of ffmpeg from FFmpeg (just download, extract, and execute) and then manually use it to convert to MP3? Does the resulting file display the correct information in the players?

comment Streaming with FFMpeg: Splashscreen?
Only other idea I have, excluding writing a patch to add -update functionality for the demuxer, is to simply stop the recording and then initiate a new ffmpeg command that just shows splashscreen.png. I don't know if that will work on Twitch or not since I'm not really familiar with the site.

comment Streaming with FFMpeg: Splashscreen?
Since x11grab will show whatever is on your screen why not just switch the focus in your windows manager (alt+tab or similar) to a fullscreen image whenever you need to use the shitter? I don't think the image2 demuxer has the -update option like the muxer does...might be a good feature request. Also, I highly recommend looking at Encoding for streaming sites with ffmpeg to optimize your stream for your, or your viewers, network speed (includes some examples too).

comment Editing AVI Metadata
You should include the complete ffmpeg console output from your command (you can add -t 10 to encode just 10 seconds).

comment Is there a build of Audacity for Ubuntu that can use a local version of FFMpeg?
@RolandiXor You can always use ffmpeg (the real one, not the fake one) to stream copy the audio: ffmpeg -i input -codec:a copy -map 0:a output or re-encode it ffmpeg -i input output.wav.

comment ffmpeg batch convert files
@Levan My examples assume that you start in the directory that contains your files that you want to convert. I'll update it to make it more clear.

comment ffmpeg batch convert files
What format are the files? Are they all the same format? Please show the complete ffmpeg console output of: ffmpeg -i one_of_the_input_files

comment How to generate a MOV-file from PNG images?
Default frame rate for input is -r 25, so if you choose a different value for output then ffmpeg will drop or duplicate frames to compensate. Sometimes this is desired by the user. If not then use -r as an input option instead.

comment FFMPEG preset question
Whoever made the script does not know what they are doing. They use -qscale but libx264 ignores that option. Even if it did support -qscale this option is mutually exclusive with -b:b. -b 64KB is used but -b is ambiguous and -b:v or -b:a should be used instead if you want to declare a specific bitrate. 64k is very low for video.

comment Convert “H264 MP4 AVC (part 10) (avc1)”/“MPEG AAC 48kHz” 1080p 23.976000fps videos to 720p, as complete quality as possible
@Rautamiekka Filtering requires re-encoding, and usage of a lossy encoder will introduce quality loss (even if you do not notice it). Using a lossless encoder will, in most cases, result in a huge file.

@Rautamiekka Also, quality is subjective so no "one answer" is perfect.

@Rautamiekka You can choose the answer as "accepted" if you found it acceptable so others know it has been answered.

@Rautamiekka placebo is a waste of time (hence the name). It helps at most ~1%. That is why I did not list it in the answer.
