  • ffmpeg - operation not permitted error while conversion

    20 février 2012, par Jomoos

    I am developing an android app. My requirement is that to implement an rtsp streaming server on android. It has to live stream video and audio captured using MediaRecorder. Another requirement is that I have to use live555 as the streaming server. What I get from MediaRecorder is in MP4 or 3GP format. live555 cannot able to stream both. But it can stream audio if I recorded it only in 'RAW_AMR' format. Since live555 support 'mpg' format for streaming, I decided to put someone in middle who can convert 'mp4' or '3gp' to 'mpg', and I chose ffmpeg.

    I have ported live555 and ffmpeg to android. ffmpeg is able to convert the file recorded by MediaRecorder once it is finished. But the problem is that ffmpeg cannot be able to do it concurrently. That is, ffmpeg is not able to convert the file while recording. It shows an Operation not permitted error. I tried the same on my linux machine, using VLC to record instead of MediaRecorder on android. The result is same. ffmpeg is able to convert once the recording is finished, and not able to do the same while recording.

    Here is the ffmpeg command I issued on my linux box :

    ffmpeg -v 9 -loglevel 99 -i test.mp4 test.mpg

    Where test.mp4 is the file to which VLC is recording in mp4 format. and test.mpg is my destination file. The following is the output by ffmpeg on terminal.

    Would anyone please tell me what is causing the problem ? Or is the scenario above is possible by ffmpeg. That is, is ffmpeg is able to do the conversion at the same time as that of recording ? If it is not possible by ffmpeg, would you please suggest any alternative solutions ?

    NOTE : I am putting a C tag because if it possible by some tweaking in C on ffmpeg, I am ready to do that(I want the solution that badly). But please provide some pointers to the right direction.

  • Opencv crosscompile with ffmpeg and other 3rdparty for arm board

    16 juin 2017, par Little Tooth

    After buliding Qt5.5.1 for my arm board sucessfully, I am taking up to crosscompile opencv. Here are the steps :

    First, I crosscompile 3rdparty :

    a.libz

    lmk@lmk-virtual-machine:/home/newdisk$ sudo tar -zvxf zlib-1.2.8.tar.gz
    
lmk@lmk-virtual-machine:/home/newdisk$ cd zlib-1.2.8
    
lmk@lmk-virtual-machine:/home/newdisk/zlib-1.2.8$ sudo ./configure --prefix=/home/newdisk/optnew/opencv-rely -shared
    
lmk@lmk-virtual-machine:/home/newdisk/zlib-1.2.8$ sudo vi Makefile

    and etit Makefile in some details :

    #Makefile
    
CC=/home/newdisk/optnew/opt/FriendlyARM/toolschain/4.5.1/bin/arm-none-linux-gnueabi-gcc
    
LDSHARED= /home/newdisk/optnew/opt/FriendlyARM/toolschain/4.5.1/bin/arm-none-linux-gnueabi-gcc -shared -Wl,-soname,libz.so.1,--version-script,zlib.map
    
AR=/home/newdisk/optnew/opt/FriendlyARM/toolschain/4.5.1/bin/arm-none-linux-gnueabi-ar
    
RANLIB=arm-linux-ranlib

    the last step is run make and make install :

    lmk@lmk-virtual-machine:/home/newdisk/zlib-1.2.8$ sudo make
    
lmk@lmk-virtual-machine:/home/newdisk/zlib-1.2.8$ sudo make install

    b.libjpeg

    lmk@lmk-virtual-machine:/home/newdisk$ sudo tar -zvxf jpegsrc.v9.tar.gz
    
lmk@lmk-virtual-machine:/home/newdisk$ cd jpeg-9
    
lmk@lmk-virtual-machine:/home/newdisk/jpeg-9$ sudo CC=/home/newdisk/optnew/opt/FriendlyARM/toolschain/4.5.1/bin/arm-none-linux-gnueabi-gcc ./configure --host=arm-linux --prefix=/home/newdisk/optnew/opencv-rely --enable-shared --enable-static
    
lmk@lmk-virtual-machine:/home/newdisk/jpeg-9$ sudo make
    
lmk@lmk-virtual-machine:/home/newdisk/jpeg-9$ sudo make install

    c.libpng

    lmk@lmk-virtual-machine:/home/newdisk$ sudo xz -d libpng-1.6.29.tar.xz
    
lmk@lmk-virtual-machine:/home/newdisk$ sudo tar -xvf libpng-1.6.29.tar
    
lmk@lmk-virtual-machine:/home/newdisk$ cd libpng-1.6.29
    
lmk@lmk-virtual-machine:/home/newdisk/libpng-1.6.29$ sudo CC=/home/newdisk/optnew/opt/FriendlyARM/toolschain/4.5.1/bin/arm-none-linux-gnueabi-gcc ./configure --host=arm-linux --prefix=/home/newdisk/optnew/opencv-rely --enable-shared --enable-static
    
lmk@lmk-virtual-machine:/home/newdisk/libpng-1.6.29$ sudo make
    
lmk@lmk-virtual-machine:/home/newdisk/libpng-1.6.29$ sudo make install

    d.yasm

    lmk@lmk-virtual-machine:/home/newdisk$ sudo tar -zvxf yasm-1.3.0.tar.gz
    
lmk@lmk-virtual-machine:/home/newdisk$ cd yasm-1.3.0
    
lmk@lmk-virtual-machine:/home/newdisk/yasm-1.3.0$ sudo CC=/home/newdisk/optnew/opt/FriendlyARM/toolschain/4.5.1/bin/arm-none-linux-gnueabi-gcc ./configure --prefix=/home/newdisk/optnew/opencv-rely --host=arm-linux
    
lmk@lmk-virtual-machine:/home/newdisk/yasm-1.3.0$ sudo make
    
lmk@lmk-virtual-machine:/home/newdisk/yasm-1.3.0$ sudo make install

    e.libx264

    lmk@lmk-virtual-machine:/home/newdisk$ sudo tar -jxvf last_x264.tar.bz2
    
lmk@lmk-virtual-machine:/home/newdisk$ cd x264-snapshot-20170612-2245 
    
lmk@lmk-virtual-machine:/home/newdisk/x264-snapshot-20170612-2245$ sudo CC=/home/newdisk/optnew/opt/FriendlyARM/toolschain/4.5.1/bin/arm-none-linux-gnueabi-gcc ./configure --enable-shared --host=arm-linux --disable-asm --prefix=/home/newdisk/optnew/opencv-rely
    
lmk@lmk-virtual-machine:/home/newdisk/x264-snapshot-20170612-2245$ sudo make
    
lmk@lmk-virtual-machine:/home/newdisk/x264-snapshot-20170612-2245$ sudo make install

    f.libxvid

    lmk@lmk-virtual-machine:/home/newdisk$ cd xvidcore-1.3.3
    
lmk@lmk-virtual-machine:/home/newdisk/xvidcore-1.3.3$ cd build/generic
    
lmk@lmk-virtual-machine:/home/newdisk/xvidcore-1.3.3/build/generic$ sudo CC=/home/newdisk/optnew/opt/FriendlyARM/toolschain/4.5.1/bin/arm-none-linux-gnueabi-gcc ./configure --prefix=/home/newdisk/optnew/opencv-rely --host=arm-linux  --disable-assembly
    
lmk@lmk-virtual-machine:/home/newdisk/xvidcore-1.3.3/build/generic$ sudo make
    
lmk@lmk-virtual-machine:/home/newdisk/xvidcore-1.3.3/build/generic$ sudo make install

    g.ffmpeg

    lmk@lmk-virtual-machine:/home/newdisk$ sudo tar -jvxf ffmpeg-3.3.2.tar.bz2
    
lmk@lmk-virtual-machine:/home/newdisk$ cd ffmpeg-3.3.2
    
lmk@lmk-virtual-machine:/home/newdisk/ffmpeg-3.3.2$
    
sudo ./configure --prefix=/home/newdisk/optnew/opencv-rely --enable-shared --disable-static --enable-gpl --enable-cross-compile  --arch=arm --disable-stripping --target-os=linux --enable-libx264 --enable-libxvid --cc=/home/newdisk/optnew/opt/FriendlyARM/toolschain/4.5.1/bin/arm-none-linux-gnueabi-gcc --enable-swscale --extra-ldflags=-L/home/newdisk/optnew/opencv-rely/lib --extra-cflags=-I/home/newdisk/optnew/opencv-rely/include
    
lmk@lmk-virtual-machine:/home/newdisk/ffmpeg-3.3.2$ sudo make
    
lmk@lmk-virtual-machine:/home/newdisk/ffmpeg-3.3.2$ sudo make install

    There is no problem in 3rdparty crosscompile.
    Next, opencv crosscompile :

    lmk@lmk-virtual-machine:/home/newdisk$ sudo unzip opencv-3.1.0.zip
    
lmk@lmk-virtual-machine:/home/newdisk$ cd opencv-3.1.0
    
lmk@lmk-virtual-machine:/home/newdisk/opencv-3.1.0$ sudo mkdir BuildOpencv
    
lmk@lmk-virtual-machine:/home/newdisk/opencv-3.1.0$ cd BuildOpencv
    
lmk@lmk-virtual-machine:/home/newdisk/opencv-3.1.0/BuildOpencv$ sudo vim toolchain.cmake
    
#toolchain.cmake

    Then I run cmake :

    While the file libavformat/avformat.h does exits in my directory

    Why can cmake find lib directory

    -- Found ZLIB: /home/newdisk/optnew/opencv-rely/lib/libz.so (found suitable version "1.2.8", minimum required is "1.2.3")

    but cannot find include directory ?

    /home/newdisk/optnew/opencv-rely/include

    Do you have any idea ?

    As seen from the screenshots there are 14 frames of difference, and later rise to 35

    Can frames be damaged and ffmpeg skip them ?

    The video for the first 13 minutes is perfectly synchronized

    FinalOutput.mpeg has the same frames as output.mpeg
    I have several TransportStreams to process and everyone has a frame difference

    someone can help me to solve the problem ?

    I need FinalOutput.mpeg to be aligned frame by frame with the original and necessarily the video must impress the timecode.

    a possible solution would also be a replace "damaged" frame but I can not find out how to replace the skipped frames

    EDIT :

    i’ve tried to work from OriginalVideo.ts and extracted video with -map directly with FFMPEG but the result is the same

    CL : ffmpeg -i OriginalVideo.ts -map 0:0 -c:v copy output.h264
