Install gstreamer on EC2 Amazon Linux AMI ?
6 décembre 2015, par vy32I’m trying to install QT5.5 on Amazon EC2 Linux, which apparently requires that I install some kind of multimedia support. It looks like that comes from gstreamer.

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
[ec2-user@ip-172-30-1-58 ~]$Supplying the suggested
--skip-broken
doesn’t help :[ec2-user@ip-172-30-1-58 ~]$ sudo yum install -y gstreamer-ffmpeg --skip-broken

What is the right command to convert an mp3 file to the required codec version (MPEG version 2) and bit rate (48 kbps) for Amazon Alexa SSML ?
6 mai 2017, par Asimov4I am trying to convert an mp3 file to the format expected by the audio tag in the Amazon Alexa SSML markup language as described here : https://developer.amazon.com/public/solutions/alexa/alexa-skills-kit/docs/speech-synthesis-markup-language-ssml-reference
The documentation recommends using https://www.ffmpeg.org/ffmpeg.html
I tried this command but can’t find the right codec to use :
ffmpeg -y -i input.mp3 -ar 44100 -ab 48k -codec:a mpeg2 -ac 1 output.mp3
I know I need to convert the file because Alexa fails with the following error :
The audio is not of a supported MPEG version

NVIDIA accelerated ffmpeg (nvenc_h264 ) is dead slow on Amazon G2 instance
16 novembre 2015, par Abhijit PathakFFMPEG when compiled with following options give abysmal performance on Amazon G2 instance( g2.2xlarge, GRID K520) when compared with standalone Dell-Precision-T1700 (Quadro-k620)
"--enable-nonfree --enable-gpl --enable-version3 --enable-shared --enable pthreads [b]--enable-nvenc[/b] --enable-runtime-cpudetect --disable-doc --enable-libmp3lame"
Above ffmpeg binary took 66 seconds to transcode 5.22 mins BVE_Localize.mp4 file with following command.
time ffmpeg -y -i BVE_Localize.mp4 -strict -2 -vcodec nvenc_h264 -b 5000k -acodec aac -ab 256k -f mpegts BVELocalize.ts ( took 1m6.990s on G2)
When same ffmpeg command is executed on Dell-Precision-T1700 (Xeon Dual core, Quadro K620) based workstation takes 0m41.572s.
I would like ffmpeg to perform better on Amazon G2 instance. What do you think I might be missing ? My Amazon G2 instance configuration is Ubuntu 14.04 64 bit, Cuda 7.0 , 352.55 drivers, MSI disabled,NVIDIA SDK 5.0.1
