  • av_read_frame function in ffmpeg in android always returning packet.stream_index as 0

    31 juillet 2013, par droidmad

    I am using the following standard code pasted below (ref : http://dranger.com/ffmpeg/) to use ffmpeg in android using ndk. My code is working fine in ubuntu 10.04 using gcc compiler. But I am facing an issue in android.The issue is av_read_frame(pFormatCtx, &packet) is always returning packet.stream_index=0. I have tested my code with various rtsp urls and I have the same behaviour in all cases. I do not have any linking or compiling issues as everything seems to be working fine except this issue. I am trying to solve this from last 2 days but I am stuck badly.Please point me in right direction.

  • Linphone OSx msx264 encryption VGA takes 97% CPU, why ?

    11 septembre 2013, par Maxim Shoustin

    I have problem and today don't know how to fix it or even from where to start.

    I have Linphone application that uses msx264 plugin.

    All stuff I run on OSx and my ffmpeg version installed from port , I didn't using selfupdate for port

    bash-3.2# port installed ffmpeg-devel

    The following ports are currently installed:
    ffmpeg-devel @20130205_0+gpl2
    ffmpeg-devel @20130328_0 (active)
    ffmpeg-devel @20130328_0+gpl2

    So I compiled and build msx264, no errors.

    Now I try to send video over CIP resolution VGA (640x480) and get huge delay 8-9 seconds, even self-view I see in big delay.

    when I configure CIF (352x288), all seems fine.

    It's really strange that self-view camera has delay 4-5 sec.

    So from logs during the session I found that msx264 plugin takes 97% CPU

    On PC (windows 7) the same code runs fine, even HD I don't see any problems.

    What is the problem should be ?
