• ffmpeg error "No such file or directory" while compiling a video file compression

  13 janvier 2016, par Abraham Gharyali

  Firstly I have checked many questions and answers related to my question, but unfortunately none of them solves my problem.

  I have implemented ffmpeg library in my project, using it for 2 tasks :

  1). adding watermark on video.

  2). video compression.

  I am able to apply watermark on recorded video successfully using this command :

  {"-y" ,"-i", "/storage/emulated/0/Booms/Videos/video1122150738.mp4","-strict","experimental", "-vf", "movie="
  
  + watermarkFile + " [watermark]; [in][watermark] overlay=main_w-overlay_w-10:10 [out]","-s", "320x240","-r", "30", "-b", "15496k", "-vcodec", "mpeg4","-ab", "48000", "-ac", "2", "-ar", "22050", "/storage/emulated/0/Shared/Videos/video.mp4"}

  "watermarkFile" is the location of .png watermark file

  Now I need to compress video, for that i used this command :

  "ffmpeg -i "+"/storage/emulated/0/Booms/Videos/video1122150738.mp4"+" -vcodec mpeg4 -s 320x240 -r 25 -y "+"/storage/emulated/0/Shared/Videos/video.mp4";

  It gives error "No such file or directory". please see the logs.

  01-11 15:32:55.663 28027-28027/ D/FFMPEG compress: Finished.

  for both operations i input .mp4 file and need .mp4 file in output.

  Same process works for watermarking and not working for compression.

  My compress command is correct because I checked the same command compressing video in my windows pc using command prompt.

  I don’t understand what i am doing wrong.

  Any help would be appreciated.

• SocialEngine "Tasks have not executed for more than 180 seconds." error on Video upload using FFMPEG

  17 juillet 2017, par Amit

  I’ve installed FFMPEG on server to support video upload in Socialengine.

  Now I can see the option to upload Video from "My Computer" but after I upload a video I see "Your video is in queue to be processed - you will be notified when it is ready to be viewed."

  If I check "Task Scheduler" in Admin panel it shows "Tasks have not executed for more than 180 seconds." with 0% progress and after a while it fails.

• gcc "relocation R_X86_64_PC32 against symbol `ff_M24A'" error when linking statically against ffmpeg on linux

  22 janvier 2016, par YB_Evil

  I am trying to build a JNI shared library which statically links to ffmpeg.

  But at the linking stage, gcc fails with the following error :

  /usr/bin/ld: ./lib_lin64/libswscale.a(swscale.o): relocation R_X86_64_PC32 against symbol `ff_M24A' can not be used when making a shared object; recompile with -fPIC

  I am using the following commands to compile my jni library :

  gcc -I $JAVA_HOME/include -I $JAVA_HOME/include/linux -I ./include -fPIC -c *.c
  

  gcc -shared -Wl,--no-undefined -o libnv_avc_dec.so *.o -Wl,-Bstatic -L./lib_lin64 -lavcodec -lavutil -lswresample -lswscale -Wl,-Bdynamic -lm

  And I only use h264 decoding feature, so I am also building ffmpeg from source with the minimal required feature set. The ./configure command I use is :

  ./configure \
--enable-pic --prefix=ffmpeg-dist \
--disable-debug --enable-version3 --enable-gpl \
--disable-everything --enable-hwaccel=h264_vdpau --enable-hwaccel=h264_vaapi --enable-hwaccel=h264_qsv --enable-hwaccel=h264_mmal \
--enable-decoder=h264 --enable-decoder=h264_vdpau --enable-decoder=h264_crystalhd --enable-decoder=h264_mmal --enable-decoder=h264_qsv \
--disable-iconv --disable-securetransport --disable-xlib --disable-zlib --disable-lzma  --disable-bzlib  --disable-doc --disable-programs --disable-avformat --disable-avfilter --disable-postproc

  So, as I understand, the linker tells me that ffmpeg should be compiled with -fPIC flag in order to make a shared library. But I believe that I’ve already done so by specifying the —enable-pic configure flag. And I am pretty much stuck here because I am not very familiar with autotools, nor with ffmpeg build process in particular.

  If this is the issue of ffmpeg .a libs not being compiled with -fPIC flag, how can i force it ? And if this is not the case, what am i doing wrong and how can i fix this error ?

  Environment details : Ubuntu 14.04.3 64-bit in Virtualbox, gcc 4.8.5 and 5.3 (both give the same results), ffmpeg v.2.8.5
