comment Ubuntu ffmpeg command -i not found
What Ubuntu version are you using? How did you install ffmpeg? If you followed a guide please provide the link. It is likely you will not need to use export or edit ~/.profile, or mess with anything like that.

comment Read bitmap data going to X server
The mouse cursor should be captured by default. I'm not sure why it does not for you. Did you compile ffmpeg yourself? Does the file /usr/include/xcb/shape.h exist on your system?

Could you also provide the complete console output from the ffmpeg command?

You should show what you tried: the ffmpeg command and the complete console output. You mentioned that you "don't need to create an mpeg", but what output format do you need?

comment How to play video using ffmpeg on ubuntu?
@ldeveloper That link returns "404 Not Found", but perhaps it is not supposed to be a http link. You need to provide the input protocol, such as http://sykiptv..., rtp://sykiptv..., rtsp://sykiptv..., etc. Perhaps VLC would be an easier player for you to use than ffplay.

comment How to play video using ffmpeg on ubuntu?
@cl-netbox Unfortunately, that guide is a mess (it's written by one well-intentioned, yet scatterbrained guy and has received no cleanup), and it about encoding for streaming, not playback. I think it will simply confuse the OP.

comment How to install ffmpeg 3.0 on Ubuntu 15.10
@NicolasRaoul Your ffmpeg is missing support for libx264, so it is using the "mpeg4" fallback which has not-so-good defaults. If you want to re-compile see FFmpeg Wiki: Compile FFmpeg on Ubuntu.

You should show your command and complete console output from the ffmpeg that you compiled.

comment how can I batch extract audio from mp4 files with ffmpeg without decompression (automatic audio codec detection)?
@jarno Probably not for this particular topic, but the Libav stuff is lacking in many features, but makes up for that with more bugs.

This is now outdated. FFmpeg is back and Libav is gone.

@jarno The real ffmpeg returned to Ubuntu in 15.04, and it looks like the Libav chaff avconv and avprobe has been removed in 15.10.

comment ffmpeg unrecognized option “draw_mouse”
Please show the complete console output from your command (without -report; it's usually way too verbose).

comment Converting mp3 with avconv keeping folder structure
Why do you specifically want to use avconv instead of ffmpeg? Why do you want to re-encode in the first place?

comment How do I use ffmpeg's -filter_complex
You must be using a super old ffmpeg. Your solution should be a last resort if you are unable to upgrade.

comment How can I convert a 1080p wmv video to a 720p video?
Using -2 instead of -1 in the scale filter will additionally ensure that the value will be divisible by 2, which is required by libx264 for videos with 4:2:0 chroma subsampling.

comment ffmpeg unable to record video with audio how to solve it?
Screenshots can't be searched, they're harder to read, text can't be copied from them, they take up more space, and take more time to make. You need to see if /dev/audio actually exists as I suggested before. I'm guessing it's actually named /dev/audio0 or something like that.
