Compile ffmpeg library statically using visual c++
6 décembre 2017, par SaeedWhen I try to compile ffmpeg library statically using visual studio 2015, with following configure options
./configure --toolchain=msvc --arch=x86 --enable-yasm --enable-asm --disable-shared --enable-staticsurprisingly, I get
.alibraries instead of.lib. How can I compile ffmpeg to generate .libs ? -
convert mp4 to m4a using ffmpeg in android
30 novembre 2017, par abdulrahmanI’m trying to add the ability to compress video files in my project. However, I tried to extract the Audio from the original video file using FFMPEG Library before compressing it. The command line was
-i video.mp4 -c:a aac -b:a 160k target.m4aAfter the encoding was done I noticed that the output is still a video file but with a difference in the size. This brought two questions to me and I would like to know their answers.
1 - can the ".m4a" file be considered as a video file ?
2 - can I use this command line to compress video files ?
Best regards
