ffmpeg -i input -c:v copy -c:a aac -b:a 256k output.mp4 while executing
it gaves me error saying [aac @ 0000000002a802e0] The encoder 'aac' is experimental but experimental codecs are not enabled, add '-strict -2' if you want to use it. [aac @ 0000000002a802e0] Alternatively use the non experimental encoder 'libvo_aacenc'. So i used ffmpeg -i input.MTS -c:v copy -c:a libvo_aacenc -b:a 256k mp4fro output.mp4 and it works . i am just curious to know why aac is not working with my version of ffmpeg [ ffmpeg Details :] ffmpeg version 2.0.2 Copyright (c) 2000-2013 the FFmpeg developers built on Oct 26 2013 06:29:32 with gcc 4.8.2 (GCC) configuration: --disable-static --enable-shared --enable-gpl --enable-version3 --disable-w32threads --enable-avisynth --enable-bzlib --enable-fontconfig --ena ble-frei0r --enable-gnutls --enable-iconv --enable-libass --enable-libbluray --e nable-libcaca --enable-libfreetype --enable-libgsm --enable-libilbc --enable-lib modplug --enable-libmp3lame --enable-libopencore-amrnb --enable-libopencore-amrw b --enable-libopenjpeg --enable-libopus --enable-librtmp --enable-libschroedinge r --enable-libsoxr --enable-libspeex --enable-libtheora --enable-libtwolame --en able-libvidstab --enable-libvo-aacenc --enable-libvo-amrwbenc --enable-libvorbis --enable-libvpx --enable-libwavpack --enable-libx264 --enable-libxavs --enable- libxvid --enable-zlib libavutil 52. 38.100 / 52. 38.100 libavcodec 55. 18.102 / 55. 18.102 libavformat 55. 12.100 / 55. 12.100 libavdevice 55. 3.100 / 55. 3.100 libavfilter 3. 79.101 / 3. 79.101 libswscale 2. 3.100 / 2. 3.100 libswresample 0. 17.102 / 0. 17.102 libpostproc 52. 3.100 / 52. 3.100 so any one can explain how i can make aac codec working with my ffmpeg On Thu, Aug 3, 2017 at 1:26 PM, Karen Norton <norto...@gmail.com> wrote: > Hi all, > > I'm not entirely sure where this was left off but thought I would weigh in. > I looked at what your output stream is for audio and unless I'm reading it > wrong it looks like it's ac3.
