  • How can I generate encoded HEVC bitstream using ffmpeg ?

    31 octobre 2014, par jgmao

    I am able to encoded YUV file to mp4 using HEVC :

    ffmpeg.exe -f rawvideo -s 1920x1080 -pix_fmt yuv420p -i input.yuv -c:v hevc -r 30 -x265-params crf=27 -vframes 300 -an -y test.mp4

    Here is the mp4box -info test.mp4 shows :

    * Movie Info *
    
        Timescale 1000 - Duration 00:00:10.000

        SPS resolution 1920x1080
    
        Bit Depth luma 8 - Chroma 8 - 1 temporal layers

    But how can I get the decodeble bit stream ? I tried

     mp4box -raw 1 test.mp4 -out out.bin

    It gives :

    Extracting MPEG-H HEVC stream to hevc

    But the out.bin couldn’t be decoded by HM or elecard.

    Thanks

  • How to avoid pumping artifacts when encoding still images into a mpeg-2 video using ffmpeg

    7 novembre 2014, par Daniel

    I’m encoding a still image into a dvd compliant mpeg stream using a command line like this :

    ffmpeg.exe -y -loop 1 -t 00:00:30 -r 1 -i "image.jpg" -target pal-dvd -b:v 6000000 video.mpg

    This generates a video of 30s showing a single still image.
    When watching the video I notice strange (and ugly) "pumping" artifacts, approximately at the end of each GOP.
    Using a stream analyzer tool I noticed that two consecutive I frames in a sequence of IPPPPPPPPPPPPPPIPPPPPPPPPPPPPP... do not look the the same as I would expect it, since there should be no reason for the encoder to change encoding parameters that influence quality.

    I also encoded the same image using the command line

    ffmpeg.exe -y -loop 1 -t 00:00:30 -r 1 -i "image.jpg" -f dvd -pix_fmt yuv420p -r 25 -s 720x576 -aspect 16:9 -vcodec mpeg2video -b:v 6000000 -maxrate 9000000 -bufsize 1835008 -muxrate 10080000 -minrate 0 -packetsize 2048 -g 15 video.mpg

    which applies more or less the same parameters that are implied by -target pal-dvd above.
    The result is the same as expected.

    Note : non still material shows less to no "pumping". It also nearly disappears when setting vbv buffer size to a higher value like 3670016 bytes, doubling it effectively.
    Unfortunately this is no option since the stream should be dvd compliant which enforces a vbv buffer size like in the command lines above.

    So how can I avoid these visual artifacts and get a stream that (really) shows a still image ?

  • Unable to use Makefile on ffmpegthumbnailer setup files with Cygwin for Windows 10

    21 août 2018, par Cole Phiper

    I am currently trying to build the exe/binary files to support ffmpegthumbnailer on Windows 10. I read multiple posts on getting it to work, but none seem to satisfy my needs. I currently have ffmpegthumbnailer-2.2.0 stored at C :\ffmpegthumbnailer-2.2.0 I see a folder named CMakeFiles, dist, kffmpegthumbnailer, libffmpegthumbnailer, man, test and thunar files. When I run make in the directory, I receive

    User@User-WIN10 /cygdrive/c/ffmpegthumbnailer-2.2.0/man
    
$ make
    
make: *** No targets specified and no makefile found.  Stop.

    How do I build/make the exec files, so that I can use the PATH variable to find ffmpegthumbnailer ?

    UPDATE 1 :
    I tried the automake command, but I received the message below

    $ automake
    
/cygdrive/c/RubyDevKit/mingw/bin/automake: /cygdrive/c/RubyDevKit/mingw/bin/automake-1.11: /bin/perl: bad interpreter: No such file or directory
    
/cygdrive/c/RubyDevKit/mingw/bin/automake: line 156: /cygdrive/c/RubyDevKit/mingw/bin/automake-1.11: No error

    UPDATE 2 :

    I ran cmake and received the message below.

CMake Warning at /usr/share/cmake-3.6.2/Modules/Platform/CYGWIN.cmake:15 (message):
    
  CMake no longer defines WIN32 on Cygwin!
    

    
  (1) If you are just trying to build this project, ignore this warning or
    
  quiet it by setting CMAKE_LEGACY_CYGWIN_WIN32=0 in your environment or in
    
  the CMake cache.  If later configuration or build errors occur then this
    
  project may have been written under the assumption that Cygwin is WIN32.
    
  In that case, set CMAKE_LEGACY_CYGWIN_WIN32=1 instead.
    

    
  (2) If you are developing this project, add the line
    

    
    set(CMAKE_LEGACY_CYGWIN_WIN32 0) # Remove when CMake >= 2.8.4 is required
    

    
  at the top of your top-level CMakeLists.txt file or set the minimum
    
  required version of CMake to 2.8.4 or higher.  Then teach your project to
    
  build on Cygwin without WIN32.
