FFMPEG "no such file or directory" on Android
25 mars 2013, par FerasI 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-ldflags="-L../x264" \
\
--enable-version3 \
--enable-gpl \

--disable-doc \
--enable-yasm \
\
--enable-decoders \

\
--enable-ffmpeg \
--enable-ffplay \
--enable-libmp3lame \
--enable-network \
\
--enable-libx264 \
--enable-libfaac \
--enable-zlibIts 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 :
