• FFMPEG "no such file or directory" on Android

  25 mars 2013, par Feras

  I am trying to use the ffmpeg binary and call it via a native linux command in android. Most of the commands work fine but the problem is that when i need to pass an http url as an input to the -i option i get "No such file or directory" for the url. The url however is existing and running the SAME command on a mac does the job as expected.

  Here is my compile config for the ffmpeg build :

  ./configure \
  
  $DEBUG_FLAG \
  
  --arch=arm \
  
  --cpu=cortex-a8 \
  
  --target-os=linux \
  
  --enable-runtime-cpudetect \
  
  --prefix=$prefix \
  
  --enable-pic \
  
  --disable-shared \
  
  --enable-static \
  
  --cross-prefix=$NDK_TOOLCHAIN_BASE/bin/$NDK_ABI-linux-androideabi- \
  
  --sysroot="$NDK_SYSROOT" \
  
  --extra-cflags="-I../x264 -mfloat-abi=softfp -mfpu=neon" \
  
  --extra-ldflags="-L../x264" \
  
  \
  
  --enable-version3 \
  
  --enable-gpl \

  --enable-libmp3lame \
  
  --enable-network \
  
  \
  
  --enable-libx264 \
  
  --enable-libfaac \
  
  --enable-zlib

  Its based off of this project : https://github.com/guardianproject/android-ffmpeg-java

  Command is something along the lines of that :

  ffmpeg -i "http://someurl" -f mp3 -ab 192000 -vn demoo.mp3

  The idea being to download the audio track from a video and encode it as mp3. I explicitly added multiple enable protocols options but nothing seems to do the job. I tried an alternative config as well, removing everything below enable-gpl just to make sure there arent any conflicts, but it fires the same error. If i give it a normal filesystem path it works fine.

  Following the comments here is the exact output of the command and the output :

• convert flv video file to m3u8 format with h264 and aac codec in ffmpeg

  27 avril 2017, par user2138489

  I want to convert a flv video file to a m3u8 container using AAC and H264 encoding in FFmpeg version 0.7.15. Can anyone help me on this ?

  I used this command to convert to the m3u8 format, but it throws an error :

• Error compiling and building DashEncoder code and how to play the .mpd file when generated [closed]

  11 avril 2013, par niuu

  I'm trying to build the DashEncoder code which I downloaded from github https://github.com/slederer/DASHEncoder. Well, I followed all the instructions given in the how to compile dash file. installed Gpac n X264 and compiled both successfully. Then did make of Dashencoder and ran it as ./Dashencoder. But I found some issues in it. Got this log :
