• FFMPEG Convert HTML 5 Video NOT Working

  2 juillet 2016, par Brad

  I am using FFMPEG to convert a video to .mp4, ,ogg, .webm so that it may be viewed in all HTML5 capable browsers using the video tag. The problem is that I manage to convert the video to the 3 required formats but it does not display the video in the video tag, all I get is IE9 : red cross, Firefox : Grey cross, could it be a problem with the conversion or is it something to do with the way I am adding them to the source of the video tag. Here is what I have done :

  1. FFmpeg command line(s) :

     ffmpeg -i test.mp4 test.mp4
     
     ffmpeg -i test.mp4 test.ogg
     
     ffmpeg -i test.mp4 test.webm

  2. Here is the video tag :

     <video height="340" width="470" preload="true" autobuffer="true" controls="true">
     
         <source src="test.ogg" type="video/ogg"></source>
     
         <source src="test.mp4" type="video/mp4"></source>
     
     </video>

  3. Webconfig lines for the video support :

     <staticcontent>
     
         <mimemap fileextension=".mp4" mimetype="video/mp4"></mimemap>
     
         <mimemap fileextension=".ogg" mimetype="audio/ogg"></mimemap>
     
         <mimemap fileextension=".oga" mimetype="audio/ogg"></mimemap>
     
         <mimemap fileextension=".ogv" mimetype="video/ogg"></mimemap>
     
         <mimemap fileextension=".webm" mimetype="video/webm"></mimemap>
     
     </staticcontent>

  It would be great if someone could send me the required parameters for ffmpeg to convert the video to the 3 required formats and an example of how they setting the source in the video tag to display them again. And any other advise would be great like how to set the quality up etc when doing the conversion.

  Thanks in advance.

• FFmpeg Runtime Error. Input/Output Error Returned

  26 avril 2013, par manutd

  I got error during tcp opening.
  Exactly to say, avformat_open_input always return -5 (input/output error).
  I looked into the source of the error code using gdb and found that getaddrinfo(in libavformat/tcp.c) function didn't work well as expected and returned the error value EIO.
  My ffmpeg source have ff_getaddrinfo(in libavformat/os_support.c) function that is linked to getaddrinfo(which function is a pointer function) but when I run the program, my program called other function in libc.so(not getaddrinfo), dynamic library. I couldn't find which function is called.
  I gave the valid url to ffmpeg. The valid url is "http://stream.radiojavan.com/radiojavan".

  I compiled ffmpeg source for Android-use and used ffmpeg version 0.8.1
  This is my configuration.

  ./configure --target-os=linux \
  
      --prefix=$PREFIX \
  
      --enable-cross-compile \
  
      --extra-libs="-lgcc" \
  
      --arch=arm \
  
      --cc=$PREBUILT/bin/arm-linux-androideabi-gcc \
  
      --cross-prefix=$PREBUILT/bin/arm-linux-androideabi- \
  
      --nm=$PREBUILT/bin/arm-linux-androideabi-nm \
  
      --sysroot=$PLATFORM \
  
      --extra-cflags=" -O3 -fpic -DANDROID -DHAVE_SYS_UIO_H=1 -Dipv6mr_interface=ipv6mr_ifindex -fasm -Wno-psabi -fno-short-enums  -fno-strict-aliasing -finline-limit=300 $OPTIMIZE_CFLAGS " \
  
      --disable-shared \
  
      --enable-static \
  
      --extra-ldflags="-Wl,-rpath-link=$PLATFORM/usr/lib -L$PLATFORM/usr/lib -nostdlib -lc -lm -ldl -llog" \
  
      --disable-ffplay \
  
      --enable-zlib \

  Any advise or help would be very appreciated.
