  • Stream Video from ios device

    29 avril 2014, par iJose

    I have integrated FFmpeg libraries to my project.

    Now

    i want stream a video that is captured using my ios device (iPhone, iPad, iPod) to an RTMP server using FFMpeg.

    I did post a similar question and googled for the same but did not end up with any solution.

    Can anyone of you suggest me a tutorial or atleast direct me as i am badly stuck over here and not able to move ahead.

    Kindly Pour your knowledge.

    Thanking you in advance.

  • Error Converting MOV to MP4 (avconv/ffmpeg)

    29 avril 2014, par user3584988

    I use: 

    avconv -i '/INPUT.MOV' -vcodec libx264 -vprofile baseline -acodec aac -strict experimental -r 24 -b 255k -ar 44100 -ab 59k 'OUTPUT.mp4'

    The conversion is done correctly and smoothly plays PC / MAC, but the video does not play on mobile devices.
    Does anyone have the same problem? How to solve it?

    Thanks in advance

  • Connection to Tvt Camera with FFmpeg via RTSP

    29 avril 2014, par Deniz Beker

    I try to connect a TVT camera with FFmpeg via RTSP. However, I cannot obtain stream info by using avformat_find_stream_info() as it is based on POST commands of HTTP. I can only obtain the codec (H.264). I already tried to increase analyze duration & probesize parameters. How can I manually set these parameters? Or how can I obtain codec parameters?

    Edit: I can obtain these parameters from a specific port. How can I make FFmpeg to connect via this HTTP port to obtain the metadata?

  • Connect ffmpeg to Visual Studio 2008

    29 avril 2014, par user2274492

    I try to connect ffmpeg to visual c++ like this, but when I type "./configure --toolchain=msvc" I have this error:

    c99wrap cl is unable to create an executable file.

    If c99wrap cl is a cross-compiler, use the --enable-cross-compile option. Only do this if you know what cross compiling means.

    C compiler test failed

    config.log:

    WARNING: pkg-config not found, library detection may fail. mktemp -u XXXXXX ./configure: line 728: mktemp: command not found WARNING: Unknown C compiler C:\c99\c99wrap cl, unable to select optimal CFLAGS check_ld cc check_cc BEGIN /tmp/ffconf..ZHENYA.500.5884.c 1 int main(void){ return 0; } END /tmp/ffconf..ZHENYA.500.5884.c C:\c99\c99wrap cl -c -o /tmp/ffconf..ZHENYA.500.5884.o /tmp/ffconf..ZHENYA.500.5884.c fatal error C1510: Cannot load language resource clui.dll. C compiler test failed.

    What's the problem? Or just send me files that you got after compilation with this (I would not have asked, but I fix this two months):

    ./configure --toolchain=msvc

    make

    make install
