  • avdevice/decklink_enc : Add support for compressed AC-3 output over SDI

    7 avril 2023, par Devin Heitmueller
    avdevice/decklink_enc : Add support for compressed AC-3 output over SDI

    Extend the decklink output to include support for compressed AC-3,
    
encapsulated using the SMPTE ST 377:2015 standard.
    

    This functionality can be exercised by using the "copy" codec when
    
the input audio stream is AC-3.  For example :
    

    ./ffmpeg -i /foo.ts -codec:a copy -f decklink 'UltraStudio Mini Monitor'
    

    Note that the default behavior continues to be to do PCM output,
    
which means without specifying the copy codec a stream containing
    
AC-3 will be decoded and downmixed to stereo audio before output.
    

    Thanks to Marton Balint for providing feedback.

  • opencv V3 mixing shared and non shared

    31 décembre 2015, par Kellerspeicher

    The current stable (V3.0.0) and unstable (V3.1.0) version of openCV is mixing shared and non shared libraries if compiled on an Ubuntu 14.04.3 LTS.

    Linking CXX shared library ../../lib/libopencv_videoio.so
    
/usr/bin/ld: /usr/local/lib/libavcodec.a(avpacket.o): relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a shared object; recompile with -fPIC
    
/usr/local/lib/libavcodec.a: error adding symbols: Bad value
    
collect2: error: ld returned 1 exit status
    
make[2]: *** [lib/libopencv_videoio.so.3.1.0] Error 1
    
make[1]: *** [modules/videoio/CMakeFiles/opencv_videoio.dir/all] Error 2
    
make: *** [all] Error 2

    Trying to create libopencv_videoio.so using libavcodec.a seems to be the problem. There is a bug report about that, but it is only giving the advice to check if libavcodec.so is installed (which is) and a workaround to use -DBUILD_SHARED_LIBS=OFF to prevent creation of shared libraries. Does anyone knows the reason for this problem. The openCV people just state the Ubuntu packaged ffmpeg library to be not correct. Any idea ?

    The problem seems to be old. I just found a very similar question not answered but commented with the advice of compiling ffmpeg with ./configure --enable-shared. But there is already a shared library /usr/lib/x86_64-linux-gnu/libavcodec.so which obviously is not found. I am not a cmake expert but couldn’t it be a problem of a miss leaded build process ?

  • How to get convert a avi to mp4 video in order to get a YouTube 1080p HD video ? [closed]

    26 mai 2012, par Swiss12000

    I have an avi video (31568 kbits/s ->video) (1411 kbits/s -> audio).
    The avi video is 7sec long and the size is 24 597KO.

    I'm trying to convert the avi video with ffmpeg to get a lighter mp4 version.

    In the command line, I've entered :

    ffmpeg -i test.avi test.mp4

    However, when I upload the video on YouTube, I can get a 720p quality maximum.

    My question is : how to convert a mp4 in order to get a 1 080p video ?

    Thank you

    edit : Am I missing something in my question. I get negative opinion, if so what can i do in order to improve my question. I'm totaly new in videos encoding. I also did lot of google reasearch about it but i find no specific answer about that issue... So I feel that my question isn't that much bad... :s
