• FFMPEG version 0.6.5 video rotate

  18 octobre 2017, par Sanjyot Shah

  I am writing a php code to rotate the video using ffmpeg 0.6.5 (This is the version installed on the client’s web-server). Unfortunately, I have not been able to find any documentation for this version of ffmpeg.

  Here is the command for ffmpeg I have written using few references I could find online.

  /usr/bin/ffmpeg -vfilters 'rotate=90' -i /hsphere/local/home/testdomain.com/ffmpeg-php-class-master/examples/media/nsa.mp4 /hsphere/local/home/testdomain.com/ffmpeg-php-class-master/examples/media/output.mp4

  The error for this command -

  array(18) [0]=> string(67) "FFmpeg version 0.6.5, Copyright (c) 2000-2010 the FFmpeg developers" [1]=> string(74) " built on Jan 29 2012 23:55:02 with gcc 4.1.2 20080704 (Red Hat 4.1.2-51)" [2]=> string(649) " configuration : —prefix=/usr —libdir=/usr/lib64 —shlibdir=/usr/lib64 —mandir=/usr/share/man —incdir=/usr/include —disable-avisynth —extra-cflags=’-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector —param=ssp-buffer-size=4 -m64 -mtune=generic -fPIC’ —enable-avfilter —enable-avfilter-lavf —enable-libdirac —enable-libfaac —enable-libfaad —enable-libfaadbin —enable-libgsm —enable-libmp3lame —enable-libopencore-amrnb —enable-libopencore-amrwb —enable-libx264 —enable-gpl —enable-nonfree —enable-postproc —enable-pthreads —enable-shared —enable-swscale —enable-vdpau —enable-version3 —enable-x11grab" [3]=> string(35) " libavutil 50.15. 1 / 50.15. 1" [4]=> string(35) " libavcodec 52.72. 2 / 52.72. 2" [5]=> string(35) " libavformat 52.64. 2 / 52.64. 2" [6]=> string(35) " libavdevice 52. 2. 0 / 52. 2. 0" [7]=> string(35) " libavfilter 1.19. 0 / 1.19. 0" [8]=> string(35) " libswscale 0.11. 0 / 0.11. 0" [9]=> string(35) " libpostproc 51. 2. 0 / 51. 2. 0" [10]=> string(135) "Input #0, mov,mp4,m4a,3gp,3g2,mj2, from ’/hsphere/local/home/testdomain.com/ffmpeg-php-class-master/examples/media/nsa.mp4’ :" [11]=> string(11) " Metadata :" [12]=> string(26) " major_brand : mp42" [13]=> string(23) " minor_version : 0" [14]=> string(39) " compatible_brands : mp42mp41isomavc1" [15]=> string(60) " Duration : 00:00:11.44, start : 0.000000, bitrate : 2163 kb/s" [16]=> string(124) " Stream #0.0(und) : Video : h264, yuv420p, 1280x720 [PAR 1:1 DAR 16:9], 2160 kb/s, 29.97 fps, 29.97 tbr, 30k tbn, 59.94 tbc" [17]=> string(24) "Unrecognized option ’vfilters’" int(1)

  The main part of the error is the last line - [17]=> string(24) "Unrecognized option ’vfilters’" int(1)

  I have tried using -vf as well instead of vfilters and I get the same error.

  Could someone please help me with any pointers ? I am open to any other technique to rotate video orientation. I have to rotate and save the video in the correct orientation.

  Thank you !

• 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 ?

  1er février 2019, par Asimov4

  I 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
