• Warning in ffmpeg : Invalid SampleDelta in STTS [closed]

  20 mars 2013, par JuCachalot

  I use ffmpeg to encode video files in order to use in HTML5 video tag. My input files are .mp4 files in h264 exported from Adobe Premiere CS5 and I want to create two output files, one in h264 - aac with higher compression in baseline profile and one in webm VP8 - vorbis.

  For some input files, I've got this warning from ffmpeg :

  [mov,mp4,m4a,3gp,3g2,mj2 @ 0x178f3a0] Invalid SampleDelta in STTS -31999

  It does not prevent me from encoding the files but I would like to ask you what does it mean and if I should care and do something about it.

  This is my command :

  ffmpeg -loglevel verbose -i inputVideo.mp4 -c:v libvpx -quality best -cpu-used 0 -crf 20 -b:v 300k -qmin 10 -qmax 42 -maxrate 350k -bufsize 1000k -threads 4 -rc_lookahead 16 -keyint_min 0 -g 360 -skip_threshold 0 -level 116 -c:a libvorbis -b:a 96k -ac 1 /home/juju/videos/outputVid.webm

  Here is the complete console output from ffmpeg :

• Fix min/max validation. Closes gh-666. Fixes #648

  20 mars 2013, par ekonijn

  Fix min/max validation. Closes gh-666. Fixes #648
  In 1.10.0, min/max validation was supported for input type="text",
  
  where min/max were interpreted as numbers.  This means min/max
  
  for date would not work : min="2012-02-13" was interpreted as min="Not a Number".
  In 1.11.0, min/max were no longer converted to numbers.  This means
  
  min/max for dates worked, but min/max for numbers failed :
  
  "50" < "150" < "1000" does not hold.
  For an example, see http://jsbin.com/awokex/3
  This commit makes the behaviour of min/max dependent on input type :
   * input type=text (or not type attribute) has numeric min/max, as in 1.10.0
  
   * input type=date has working min/max for type date ;
  
     on mobile browsers you also get a date picker,
  
     plus the browser may reject invalid dates before
  
     javascript gets a chance to complain.
  
   * input type=number or range get numeric min/max,
  
     plus numeric keypad or slider on mobile browsers,
  
     plus browser may reject invalid input before javascript
  
     gets a chance to complain
  Allowing use of min/max with type=number/range/date is important
  
  for mobile browsers, where the numeric keypad or date picker
  
  make the input much easier to use than a generic text input field.
  
  In this situation jquery-validate remains necessary to support
  
  older browsers that do not do input validation based on type
  
  and min/max.
  For situations where numeric input should be validated by jquery
  
  without giving the browser a chance to validate the input format,
  
  input type=text in combination with min/max can be used, as in 1.10.0.
  

• unable to compile ffmpeg for iOS

  25 mars 2014, par HaneTV

  I'm trying to compile FFmpeg for iOS (for iPhone5, in order to do some RSTP streaming stuff) following the tutorial here but I get stuck with this error :

  /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc is unable to create an executable file.
  
  C compiler test failed.

  In my config.log file I have this :

  I have other errors with other scripts found on stackoverflow or with google

  Any idea ?

  Ok (i'm kinda new on mac environment), I managed to pass the configure step by fixing the sdk target to the last sdk I have (6.1), removing Other Linker Flags but then the "make" command is full of errors (either with gcc or arm-apple-darwin10-gcc-4.2) :
