• FFMpeg : CFLAGS=-D__STDC_CONSTANT_MACROS ./configure where ?

  24 avril 2013, par olidev

  I got this problem " 'UINT64_C' was not declared in this scope" while using the ffmpeg library for Eclipse running under Ubuntu.

  After a while, I have found this solution : http://code.google.com/p/ffmpegsource/issues/detail?id=11

  But I could not know how to this :

  This should be fixed in our build system no matter what version of ffmpeg you're using. If you're still getting it, run configure like so :
  CFLAGS=-D__STDC_CONSTANT_MACROS ./configure
  and your problems should go away. This applies to other C++ programs using ffmpeg as well and not just to ffms2, but I can't guarantee that other programs won't break if you define that macro (they really shouldn't, though).

  Where can I run the configure ? from Terminal ? I tried with Terminal but it does not work.

  Anybody has an idea how to run the configure ?

  Thanks in advance and your help is much appreciate !

• FFMPEG Outputs gets blurry when scaled

  17 octobre 2022, par Ps Sarvna

  I'm trying to scale my input video to standard 1280x720 resolution, but my output looks blurred when compared to the input.

  


  FFMPEG CMD

  


  ffmpeg -i input.webm -filter_complex "[0:v] scale=1280.0:720.0 [v0]" -map [v0] output.webm
