  • ffmpeg vaapi and drawtext

    31 mai 2017, par Viktor Joras

    Simple question like hell :
    Is it possible to use hardware accelerated transcoding with ffmpeg, Intel CPU and VAAPI using text overlay with drawtext ?

    My current working command without drawtext is :

    ffmpeg -vaapi_device /dev/dri/card0 -hwaccel vaapi -hwaccel_output_format vaapi  -i /file.mp4 -vf 'format=vaapi|nv12,hwupload' -threads 8 -vcodec h264_vaapi -acodec copy -scodec copy  -b:v 3000k /file2.mp4

    but it seems hwaccel and drawtext filter cannot coexist, at least as it seems at a first glance.

  • 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 :

    lmk@lmk-virtual-machine:/home/newdisk/opencv-3.1.0/BuildOpencv$ sudo cmake -DCMAKE_TOOLCHAIN_FILE=toolchain.cmake ../

    Why can cmake find lib directory

    Do you have any idea ?

  • ffmpeg Error while filtering : Cannot allocate memory

    7 juillet 2017, par Andres MERE

    My workstation seems to have plenty of memory (and everything). When I am trying to run ffmpeg as follows :

    /usr/local/bin/ffmpeg \
    
    -loglevel debug \
    
    -i "A066C002_170619NU_CANON.mov" \

    -y \
    
    "A066C002_170619NU_CANON.mp4"

    It fails with "Error while filtering : Cannot allocate memory".
