  • Questions about empty cmake FIND macros

    12 mai 2014, par Ken Li

    I have a macro that looks like this

    MACRO(FFMPEG_FIND varname shortname headername)
    
    MESSAGE(STATUS "FFMPEG_${varname}_LIBRARIES: ${FFMPEG_${varname}_LIBRARIES}")
    
    MESSAGE(STATUS "FFMPEG_${varname}_INCLUDE_DIRS: ${FFMPEG_${varname}_INCLUDE_DIRS}")
    
ENDMACRO(FFMPEG_FIND)

    which is called like this :

    FFMPEG_FIND(LIBAVFORMAT avformat avformat.h)
    
FFMPEG_FIND(LIBAVDEVICE avdevice avdevice.h)
    
FFMPEG_FIND(LIBAVCODEC  avcodec  avcodec.h)
    
FFMPEG_FIND(LIBAVUTIL   avutil   avutil.h)
    
FFMPEG_FIND(LIBSWSCALE  swscale  swscale.h)  # not sure about the header to look for here.

    Which will give us the output of

    -- FFMPEG_LIBAVFORMAT_LIBRARIES: F:/Dev/Lib/ffmpeg-20140507-git-4cdea92-win32-de
    
v/lib/avformat.lib
    
-- FFMPEG_LIBAVFORMAT_INCLUDE_DIRS: F:/Dev/Lib/ffmpeg-2.2.1
    
-- FFMPEG_LIBAVDEVICE_LIBRARIES: F:/Dev/Lib/ffmpeg-20140507-git-4cdea92-win32-de
    
v/lib/avdevice.lib
    
-- FFMPEG_LIBAVDEVICE_INCLUDE_DIRS: F:/Dev/Lib/ffmpeg-2.2.1
    
-- FFMPEG_LIBAVCODEC_LIBRARIES: F:/Dev/Lib/ffmpeg-20140507-git-4cdea92-win32-dev
    
/lib/avcodec.lib
    
-- FFMPEG_LIBAVCODEC_INCLUDE_DIRS: F:/Dev/Lib/ffmpeg-2.2.1
    
-- FFMPEG_LIBAVUTIL_LIBRARIES: F:/Dev/Lib/ffmpeg-20140507-git-4cdea92-win32-dev/
    
lib/avutil.lib
    
-- FFMPEG_LIBAVUTIL_INCLUDE_DIRS: F:/Dev/Lib/ffmpeg-2.2.1
    
-- FFMPEG_LIBSWSCALE_LIBRARIES: F:/Dev/Lib/ffmpeg-20140507-git-4cdea92-win32-dev
    
/lib/swscale.lib
    
-- FFMPEG_LIBSWSCALE_INCLUDE_DIRS: F:/Dev/Lib/ffmpeg-2.2.1
    
-- Configuring done
    
-- Generating done

    My first question is how is cmake even finding the libraries on my hard drive while the FIND macro is essentially empty. The more important question being, why is INCLUDE_DIRS set to F:/Dev/Lib/ffmpeg-2.2.1 which is a path that doesn’t even exist (there is no ffmpeg-2.2.1 folder in F :/Dev/Lib), as it should be pointing to F:/Dev/Lib/ffmpeg-20140507-git-4cdea92-win32-dev/include

  • Find timestamps of videos split using FFmpeg

    13 décembre 2017, par Spandan Thakur

    I am able successfully able to split a video with FFmpeg using the below command

    ffmpeg -i Sample.mp4 -c copy -map 0 -segment_time 900 -f segment -reset_timestamps 1 output%03d.mp4

    This will split videos into 15 mins chunks (900 seconds) however this is not 100% accurate.

    Is there a way to add the starting and ending timestamp of each segment, in the output file name, relative to the original file ? Or generate a file containing the timestamps ?

    I want to know exactly where the cuts where made. I do not want to slow down the process though by forcing FFmpeg to cut at exactly 15 mins.
