    input :

    


    


    Two audio file, It may be stereo or mono.

    


    


    output :

    


    

      

    • A stereo file, and the stereo FL uses one file all channels, and FR uses other file all channels.

      • 


    • The total duration is based on the longest file.

      • 


    • I hope it can be achieved through FFmpeg.

      • 


    


    


    There are four case :

    


      

    • mono + mono -> stereo

      • 


    • mono + stereo -> stereo

      • 


    • stereo + mono -> stereo

  • Why do I get "method DESCRIBE failed : 401 Unauthorized "

    28 juillet 2021, par TheOliveTurtle

    Let me explain my problem, I am trying to access different channels in a DVR system.
I have successfully gotten access to a single camera (channel 1) by using opencv as such :

    


    public_link = 'rtsp://test:test@192.168.1.48/cam/realmonitor'

cap = cv2.VideoCapture(public_link, cv2.CAP_FFMPEG)


    


    The problem is I can't access the other channels with these parameters :

    


    public_link = 'rtsp://test:test@192.168.1.48/cam/realmonitor?channel=3&subtype=0'

cap = cv2.VideoCapture(public_link, cv2.CAP_FFMPEG)


    


    I've tried the following links :

    


      

    • rtsp ://test:test@192.168.1.48/cam/realmonitor ?channel=3&subtype=0

      • 


    • rtsp ://test:test@192.168.1.48/cam/realmonitor ?channel=3&subtype=1

      • 


    • rtsp ://192.168.1.48/cam/realmonitor ?channel=3&subtype=0&authbasic=dGVzdDp0ZXN0

      • 


    


    I get this following error :

    


    


    [rtsp @ 00000201ce582cc0] method DESCRIBE failed : 401 Unauthorized

    


    


    I've noticed that even if I test with this URL (rtsp ://test:test@192.168.1.48/blablabla) it works just fine ! (ONLY Channel #1) but when I insert the symbol '=' into the URL string, I get the above error.

    


    It's really frustrating, Any sort of help would be much appreciated.

    


    PS : the user 'test' has admin privileges in the system.

    


    I've tried to run the test with plain ffmpeg command like such :
ffmpeg -loglevel debug -i "rtsp://test:test@192.168.1.48/cam/monitor?channel=3&subtype=0" ./folder/output.m3u8

    


    I get the following error :

  • FFmpeg make : *** [libavdevice/avfoundation.o] Error 1

    29 décembre 2014, par Althen Lim Zi Xuan

    I’m very new (1 weeks ago) to Mac OS environment and I have to create a iPhone apps using FFmpeg (I’m new to this, too !). This is what I’ve done to import FFmpeg library.

    First, here’s the environment :

    OS: Mac OS X 10.7.5
    
Xcode: 4.5
    
FFmpeg: 2.5 (Latest update of 04/12/2014)

    So I download from FFmpeg.org using command :

    git clone git://source.ffmpeg.org/ffmpeg.git ~/ffmpeg

    and create the folder in it :

    cd ffmpeg
    
mkdir i386
    
mkdir armv7
    
mkdir armv7s
    
mkdir -p universal/lib

    I download the gas-preprocessor.pl from yuvi and copied into /usr/bin and /usr/local/bin with READ/WRITE access for all.

    However, I do encounter the error as title mentions during the making process of armv7 and armv7s which appear like this :

    make: *** [libavdevice/avfoundation.o] Error 1

    Can anyone teach me how to deal with it ? Here’s my configuration.

    For i386 : (Compilation success and I saw files and folder in i386 folder)

    ./configure --cc="/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/gcc" --as="/usr/local/bin/gas-preprocessor.pl /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/llvm-gcc-4.2/bin/arm-apple-darwin10-llvm-gcc-4.2" --sysroot="/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator6.0.sdk" --target-os=darwin --arch=i386 --cpu=i386 --extra-cflags="-arch i386" --extra-ldflags="-arch i386 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator6.0.sdk"--prefix=compiled/i386 --enable-cross-compile --enable-nonfree --enable-gpl --disable-armv5te --disable-swscale-alpha --disable-doc --disable-ffmpeg --disable-ffplay --disable-ffprobe --disable-ffserver --disable-asm --disable-debug

    For armv7 :

    ./configure --cc=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc --as="/usr/local/bin/gas-preprocessor.pl /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/llvm-gcc-4.2/bin/arm-apple-darwin10-llvm-gcc-4.2" --sysroot=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.0.sdk --target-os=darwin --arch=arm --cpu=cortex-a8 --extra-cflags="-arch armv7" --extra-ldflags="-arch armv7 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.0.sdk" --prefix=compiled/armv7 --enable-cross-compile --enable-nonfree --enable-gpl --disable-armv5te --disable-swscale-alpha --disable-doc --disable-ffmpeg --disable-ffplay --disable-ffprobe --disable-ffserver --disable-asm --disable-debug

    and for armv7s :

    ./configure --prefix=armv7s --as="/usr/local/bin/gas-preprocessor.pl /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/llvm-gcc-4.2/bin/arm-apple-darwin10-llvm-gcc-4.2" --disable-ffmpeg --disable-ffplay --disable-ffprobe --disable-ffserver --enable-avresample --enable-cross-compile --sysroot="/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.0.sdk" --target-os=darwin --cc="/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc" --extra-cflags="-arch armv7s -mfpu=neon -miphoneos-version-min=6.0" --extra-ldflags="-arch armv7s -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.0.sdk -miphoneos-version-min=6.0" --arch=arm --cpu=cortex-a9 --enable-pic

    If any necessary information needed please do inform me and I will upload it A.S.A.P. Any help, comment, guideline are highly appreciated. Thanks !

    Updated :
    This is the error I received during the making process. I have no idea but hope that it helps in configuring out problem :
