• Manually Adding h265 codec support to FFMPEG v1.0.10

  11 mars 2018, par Joe90210

  I have looked everywhere and I can’t seem to find a solution. I am using Debian 7 wheezy, I have managed to get as far as having the following version installed.

  ffmpeg version 1.0.10 Copyright (c) 2000-2014 the FFmpeg developers
  
  
  
  built on Jul 25 2014 07:50:40 with gcc 4.7 (Debian 4.7.2-5)

  But as you will see below there is no H265 support which is making for a real headache trying to convert iOS MOV files to MP4. Has anybody had any luck with this ordeal ? I’ve looked through stackoverflow for 3 hours and see nothing even close here.

   ffmpeg -codecs | grep h26
  
   DEV.L. h261                 H.261
  
   DEV.L. h263                 H.263 / H.263-1996, H.263+ / H.263-1998 / H.263 
  
   version 2
  
   D.V.L. h263i                Intel H.263
  
   DEV.L. h263p                H.263+ / H.263-1998 / H.263 version 2
  
   DEV.LS h264                 H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10 (decoders: h264 h264_crystalhd h264_vdpau ) (encoders: libx264 libx264rgb )

  Using a different software version at this time is not an option, I am aware of how lacking the packages can be with Debian.

  Thank you

• Python can't see FFMPEG (Mac) [duplicate]

  This question already has an answer here :

  • IDLE and Python have different path in Mac OS X

  I’m trying to run ffmpeg commands as subprocesses in Python (3.7.4) on a Mac (OS X 10.13.4) so that I can extract frames from a video and have them tagged with the date/time they were pulled, but I always get the error :

  FileNotFoundError : [Errno 2] No such file or directory : ’ffmpeg’ : ’ffmpeg’

  How do I get Python to see ffmpeg ?

  I currently have ffmpeg operating via terminal and can successfully run ffmpeg and ffprobe operations on the same test.mp4 video referenced below in inputFilename.

  In Python, I’ve tried subprocess.run(), subprocess.Popen() and subprocess.call(). All return the same error.

  import subprocess
  
  import datetime
  
  
  
  ### - VARIABLES - ###
  
  seekToSec = 3600
  
  inputFilename = '/Users/edit/Desktop/test.mp4'
  
  currentTimeStr = datetime.datetime.now().strftime('%Y%m%d_%H%M%S')
  
  outputFilename = '/Users/edit/Desktop/frameGrab' + currentTimeStr + '.jpg'
  
  
  
  command = ['ffmpeg',
  
             '-ss', str(seekToSec),
  
             '-i', inputFilename,
  
             '-vframes', '1',
  
             outputFilename]
  
  
  
  ### - MAIN - ###
  
  subprocess.call(command)

  Thanks for the help !

• How Many Default Languages ?

  26 janvier 2012, par Multimedia Mike — Programming

  I was thinking back to my childhood, when my family first owned a computer. It was an MS-DOS-powered IBM PC. The default OS came with 2 programming environments, such as they were : GW-BASIC and batch files. It was a start, I suppose. I guess most any microcomputer you can name from that era came with some kind of BASIC interpreter. That defined the computer’s “out of the box” programmability.

  Then I started wondering how this compares to computers (operating systems/distributions, really) these days. So I installed a fresh version of the latest Ubuntu Linux version (11.10 as of this writing ; x86_32) and looked for programmability (without installing anything else). This is what I came up with :

  1. gcc/C (only the C compiler ; other components of the GNU compiler collection are installed separately)
  2. Perl
  3. Python
  4. C#, as furnished by Mono
  5. Bash — can’t forget about the shell as a full-featured programming language (sh is also present, but not t/csh)
  6. JavaScript — since Firefox is installed per default, JS counts
  7. GNU Assember — thanks to Reimar for the reminder that if gcc is present, gas necessarily needs to be there as well

  I checked on C++, Objective C, Java, Ada, Fortran, Go, Lua, Ruby, Tcl, PHP, R and other languages I could think of, but the above items were the only ones present by default. At the same time, I checked my Mac OS X (10.6) box and it also has Ruby and PHP installed. It has a bunch of other languages, courtesy of Xcode, so I can’t certify anything about its out of the box programmability.

  Still, I think “embarrassment of riches” pretty well sums it up. I try not to be crotchety old fogey complaining that kids these days don’t know how good they have it ; rather, I’m genuinely excited for anyone who wants to leap into computer programming in this day and age.
