Anybody recommend a GUI app (preferably in Ubuntu repos) to convert from .flv to .mp4 other than Transmageddon? Transmageddon now crashes in Trusty.
I don't think so there is GUI app is available in Ubuntu repository.
But you can simply convert your required formats in terminal. Try the following,
First you have to install
libav-tools, Open terminal(Ctrl+Alt+T) and type the below command,
$ sudo apt-get install libav-tools
Now you can do your needs, for FLV file to MP4
$ avconv -i input.flv -codec copy output.mp4
Have a look at winff
It is a graphical application that uses
ffmpeg (like a lot of other programs) to convert videos and audio.
It is included in the official Ubuntu repositories, so you can simply install it with
sudo apt-get install winff
The official website includes a link to a wiki and a mailing list if you need specific support and documentation with this tool
Handbrake is in the official repositories since Trusty (14.04). It is a small, efficient DVD ripper and video transcoder with a clean GTK GUI.
It can convert from a number of video formats, including flv, to either MPEG-4 or Matroska.
$ sudo apt-get install handbrake
Abstract from the blog Transcoding an audio or a video file - http://www.frasq.org/en/transcoding-an-audio-or-a-video-file (look for mp4flv in the page):
To convert a FLV already containing a video in H264 and an audio in AAC in MP4:
ffmpeg -i file.flv -acodec copy -vcodec copy -y video.mp4 MP4Box -raw 1 video.mp4 -out video.h264 MP4Box -raw 2 video.mp4 -out audio.aac MP4Box -add video.h264 -add audio.aac file.mp4 rm -f video.mp4 video.h264 audio.aac
If the FLV contains an audio in MP3, extract the video while converting the MP3 in AAC:
ffmpeg -i file.flv -vcodec copy -y video.h264 -f adts -ar 44100 -f wav -ac 2 - | faac -b 128 -o audio.aac -
Assemble the MP4 with MP4Box:
MP4Box -add video.h264 -add audio.aac file.mp4
The blog explains how to install ffmpeg, faac, MP4Box, etc.
La version en français : Transcoder des fichiers audio et vidéo - http://www.frasq.org/fr/transcoder-des-fichiers-audio-et-video
avconv -i input.flv -c:a copy output.mp4
This has the effect of transcoding the video stream with the default codec and copying the audio stream.
avconv can be installed with
sudo apt-get install libav-tools
It's not in the Ubuntu repository, but I liked Format Junkie for video conversions:
sudo add-apt-repository ppa:noobslab/apps
sudo apt-get update
sudo apt-get install formatjunkie
I've written a GUI (named ConvertFLVToMP4)for CLI avconv program. Its .deb can be downloaded from: https://app.box.com/s/vyr473g7q2nwkj6haq22 It requires the installation of gambas3 from: https://launchpad.net/~gambas-team/+archive/ubuntu/gambas3 before installing the app from the .deb.
