@DominicIsaiah Please provide a pastebin link showing your command and the complete console output. What player did you use? Can you provide the input file?

comment Split a large video file into small clips 15 sec each
@DominicIsaiah I updated the example to include the Desktop in the path to the input. See Ubuntu Wiki: Using the Terminal - File & Directory Commands for more info.

comment avconv uses only the first image in directory
Try a build from the link I provided. Just download, extract, then run. Navigate to the directory containing the ffmpeg binary, then run ./ffmpeg .... The real ffmpeg returned to Ubuntu in 15.04. The long absence was due to the maneuverings of the package maintainer who aligned himself with Libav and switched Ubuntu to this fork. It provides avconv and the counterfeit "ffmpeg" in earlier Ubuntu releases.

comment avconv uses only the first image in directory
Does a recent static build of ffmpeg exhibit the same behavior?

comment AAC to AC3 avconv failing on some Files
Your input Film.mkv appears to already contain ac3 audio. Why are you using ac3_fixed (fixed point) instead of ac3 (floating point)? At least with ffmpeg the floating point ac3 encoder will provide better quality. I'm not sure about avconv: I don't use it (does anyone?).

comment FFmpeg use AAC encoder
As for -qscale with no stream specifier, using it with a non-ancient ffmpeg build will result in various messages: Please use -q:a or -q:v, -qscale is ambiguous and [libx264] -qscale is ignored, -crf is recommended. For aac it is ignored as well. This can be confirmed by using the md5 muxer.

comment FFmpeg use AAC encoder
The deprecated message refers to the fake, now dead "ffmpeg" from Libav, not ffmpeg from FFmpeg. Unfortunately the message did not make any distinction causing many users to assume it referred to ffmpeg from FFmpeg (some assume this was intentional). The package maintainer refused to clarify the message to be less confusing in that aspect although I requested a change, but this was unsurprising since he is also a Libav dev. FFmpeg returned to Ubuntu in 15.04.

comment FFmpeg use AAC encoder
Why do you answer with an avconv example? avconv != ffmpeg (although in this case it probably would not be too much different). Also, I'm guessing avconv will ignore -qscale if libx264 is being used as the encoder, or at least ffmpeg will; I'm not a user of avconv so you will have to check.

comment FFmpeg use AAC encoder
It is possible that you may not need to perform any re-encoding. Please show the complete console output of ffmpeg -i 5.mp4.

comment How to control volume in FFMPEG
@gertvdijk ffmpeg can actually be used as a media player via the various output devices (such as sdl).

comment How to replace avconv with (the real) ffmpeg and have it work right?
Symlinking should point to /usr/local/bin to prevent potential conflicts from any repo packages that provide the named files; notably from libav-tools package qt-faststart and the faux "ffmpeg" for 12.04 and older. Also, other users may not have the proper permissions to execute anything in another user's ~/bin (but I didn't investigate this). Lastly, I think the whole "/UPDATE" section from this answer can be removed: it is outdated (that PPA is gone) and does not contribute much anymore.

comment How to make ffmpeg executable everywhere?
The guide installs to ~/bin, and this directory is already in the $PATH, so no need to edit the $PATH. See my answer for more details.

comment Merge multiple webm files using avconv
Please download a recent ffmpeg build and then show some info about your inputs. It will help me provide an answer, and avconv doesn't have the functionality of what I'm going to suggest. Include the full output of: ffmpeg -i input0.webm -i input1.webm -i input2.webm, etc.

comment Merge multiple webm files using avconv
The fake ffmpeg from Libav is what was deprecated for avconv; not ffmpeg from FFmpeg. Unfortunately the maintainer refused to clarify that in the message resulting in confused users (and some think it was the intended effect).

comment avformat package seems to have outdated headers
It was a lot of work to get FFmpeg back in Debian.

comment Ffmpeg 2.5.2 executable not replacing existing version
I'm not sure why it was not persistent for you. Also, I don't know why ~/bin doesn't seem to be in the $PATH by default since it's already in ~/.profile last I checked, but that was a while ago since I'm not personally using Ubuntu. Anyway, if you found a solution you can provide it as an answer.
