• FFMPEG version 0.6.5 video rotate

  31 mars 2016, 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 !

• ffmpeg records screen without end [closed]

  11 avril 2021, par josh joyer

  I used command

  


  ffmpeg -f gdigrab -framerate 10 -i desktop _mm.mp4


  


  While it starts, it never ends. It ignores even ctrl+c or ctrl+z finish command keypresses.

  


  How to stop screen recording and enjoy video ?

  


  I already solved this. That was problem to older version
of ffmpeg. I downloaded newest version and just press Q to stop recording.
Itworks fine in contrast to older vrsion.

  


• Concatenate multiple videos with a black screen loop into one video

  21 mars 2016, par AHC

  I am using ffmpeg to join a bunch of videos together.
  I am using the classic join ffmpeg code :
  

  ffmpeg -f concat -i joinlist.txt -c copy joinedfile.mp4

  but the problem is that the videos are of different formats, encodings, but the same size : all 640x480. I want to join them all and put a black screen video with no sound every other video :

  video1 + black_screen_video + video2 + black_screen_video + video3 ...

  I generated a black screen video of 2 seconds duration using :

  ffmpeg -f lavfi -i color=c=black:s=640x480:d=2 black_screen_video.mp4

  so all of the videos are of the same size : 640x480, and 25 fps but different codecs. The videos have sound, except for the black screen video.
  I can’t do anything manual, because the number of videos are around several hundred. So it has got to be an automatic way to do all this.

  When I joined them together using the above code, the resulting video does not play correctly at all.

  I know that I have to re-encode them, but how to do this to all these videos at once, with one line of code ?

  Update :
  I am already using with success this code to join them together, but only three, if I have more than one hundred, it is time consuming to write down one by one :

  ffmpeg -i vid1.avi -i vid2.avi -i vid3.avi -filter_complex "[0:v:0] [0:a:0] [1:v:0] [1:a:0] [2:v:0] [2:a:0] concat=n=3:v=1:a=1 [v] [a]" -map "[v]" -map "[a]" output.mp4

  but this is joining only the videos, not looping the black screen video. When I do with black screen, ffmpeg gives me stream matching errors.

  update :

  here is the console image :
  

  2nd update :

  a very long list of errors in red, of which a screenshot here :
