  • Integrating ffmpeg in xcode5, Cannot find gcc

    22 juin 2014, par user2007547

    I have been trying to integrate ffmpeg in xcode5.
    The step [here][1]

    [1] : FFMPEG integration on iphone/ ipad project says that cc parameter needs to be gcc in iphoneOs.platform.

    But I could not find it in my xcode5.
    It is present in xcode 4.6.3 that I have.

    I tried the ./configure command with cc as gcc from xcode4.
    Something like this :

    ./configure --prefix=armv7 --disable-ffmpeg --disable-ffplay --disable-ffprobe --disable-    ffserver --enable-avresample --enable-cross-compile --   sysroot="/Applications/Xcode5.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk" --target-os=darwin --cc="/Applications/Xcode4.6.3.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc" --extra-cflags="-arch armv7 -mfpu=neon -miphoneos-version-min=6.0" --extra-ldflags="-arch armv7 -isysroot /Applications/Xcode5.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk -miphoneos-version-min=6.0" --arch=arm --cpu=cortex-a9 --enable-pic

    It works ok but then the make command after fails like this :

    libavcodec/arm/mdct_vfp.S:113:unknown register alias 'TCOS_D0_HEAD'
    
libavcodec/arm/mdct_vfp.S:114:unknown register alias 'TCOS_D1_HEAD'
    
libavcodec/arm/mdct_vfp.S:115:unknown register alias 'TCOS_S0_TAIL'
    
make: *** [libavcodec/arm/mdct_vfp.o] Error 1

    What am I doing wrong here ?? Where can I find gcc for xcode5 ??

  • Can not play local rtsp URL using FFmpeg in iOS

    12 juin 2015, par Priyanka

    I am using FFmpeg for stream rtsp URL in iOS.
    I am trying to stream a local url but my app is failed to open url
    avformat_open_input method always return -5

    I have played the same url rtsp://172.16.1.226:5544/1 on VLC media player on my iPhone and macbook it works on both.

    After few research i have found there is some problem with rtsp_transport

    I was using av_dict_set(&serverOpt, "rtsp_transport", "tcp", 0); for the server configuration while opening url and the result is can not open feed.

    When I changed it to av_dict_set(&serverOpt, "rtsp_transport", "udp", 1);
    I am able to open url successfully but I continuously getting error rtsp 1 missing packet and so on.

    Can anybody help what should be the right configuration while opening a local rtsp url using ffmpeg.
    Should i need to update av_dict_set(&serverOpt, "rtsp_transport", "udp", 1)

    Thanks in advance

  • [iOS]Use ffmpeg to add watermark(overlay) for video with image : JPG is OK, bug PNG is not useful 

    2 avril 2017, par WellBeing

    My test platform is iPhone.

    Some one told me to install zlib and libpng,

    and then rebuild ffmpeg with —enable-decoder=png —enable-encoder=png,

    but it is no useful,

    Use "ffmpeg -codecs" command, I find that the PNG decoder is exist.

    There is no problem when use JPG file, but PNG file is no useful

    I can’t see anything about watermark on the video

    The last log is :

    Generic error in an external library

    If the problem is on building of ffmpeg, how can I fix it ?

    Thank you very much !
