  • Capturing Clear Stills from H264 Stream

    22 octobre 2013, par David Findlay

    I'm trying to capture still images from a H264 wireless IP camera using FFMPEG. I found a similar question here : How can I extract a good quality JPEG image from an H264 video file with ffmpeg ?

    ffmpeg -y -i rtsp://10.2.69.201:554/ch0_0.h264 -r 10 -f image2 /var/www/camera.jpg

    I've implemented it as shown in that example. You can see a sample of the image I'm getting here : http://storm.woodypointcomms.com.au/camera.jpg. Basically the issue is the bottom part of the image is always blocky. If the sky has more detail and clouds the whole bottom half of the image may be blocky or blurry.

    My camera has limited stream options. One of which is I-Frame interval, you can vary it between 25-100 kbps.

    Does anyone have some suggestions about how I can get a better image ?

  • Ffmpeg-Build : Error during build

    13 mars 2014, par talhamalik22

    I am building ffmpeg and stuck in an unusual spot. Inside libavutil we have float_dsp.h and float_dsp.c files. Inside these file there is a declaration of a methond which is :

    void (*butterflies_float)(float *av_restrict v1, float *av_restrict v2, int len);
    
float (*scalarproduct_float)(const float *v1, const float *v2, int len);

    when building and compiling this file i get this error and have no idea what to do. I think problem is somewhere else but again have no idea at all. Error is

    jni/ffmpeg/libavcodec/../libavutil/float_dsp.h:150: error: expected ';', ',' or ')'  before 'v1'
    
jni/ffmpeg/libavcodec/../libavutil/float_dsp.h:161: error: expected ';' before 'float'

    Anybody who wants to help please take a step forward because i have not really got any support on ffmpeg during couple of weeks now.

    Regards

make: *** [ffmpeg_frame.lo] Error 1

    i read that if i get the

    make: *** [ffmpeg_frame.lo] Error 1

    error , i replace all *PIX_FMT_RGBA32* with *PIX_FMT_RGB32* inside *ffmpeg_frame.c*. but when i search the file , there is no *PIX_FMT_RGBA32* . there are all PIX_FMT_RGB32 ! .
    so i have no idea what is wrong with it .
    can anyone please help me get this going ?
    Thanks in advance

    Edited :
    Thanks to God , i finally found the cause of the problem .
    when i was trying to replace PIX_FMT_RGBA32 with PIX_FMT_RGB32 inside ffmpeg_frame.c* using VI i mistakenly messed the source code (the ffmpeg_frame.c) and removed a comment sign (*/ ) and that messed just everything :)
    i re extracted all files and then replaced all PIX_FMT_RGBA32 with PIX_FMT_RGB32 and everything compiles just fine :)
