I can render a file, but when I play it I only hear the audio. I tried swapping out aac for acodec=libmp3lame and as I thought this didn't affect anything. I might be misunderstanding this thread, but my problem is not audio it's video. I need to verify, why.Ĭode: ffmpeg version git-e4f14c3 Copyright (c) 2000-2013 the FFmpeg developersīuilt on 18:16:31 with gcc 4.6 (Ubuntu/Linaro 4.6.3-1ubuntu5)Ĭonfiguration: -enable-gpl -enable-libass -enable-libfaac -enable-libfdk-aac -enable-libmp3lame -enable-libopencore-amrnb -enable-libopencore-amrwb -enable-librtmp -enable-libtheora -enable-libvorbis -enable-libvpx -enable-x11grab -enable-libx264 -enable-nonfree -enable-version3 BTW I did this latter, and then I could render with the predefined h.264 profile, but now somehow the libfaac encoder disappeared from my ffmpeg.
Either change the rendering profile (I think you can not change the predefined profile in kdenlive, but you can click on it, then click on 'Create new profile', which creates a new profile based on the selected one, and then change the option acodec=libfaac to acodec=aac), or recompile ffmpeg-extra as suggested. I'm not sure what is true and what is opinion.įinally the built in encoder needs work or you need a different set of settings to make the encoded files sound nice, i did a test between that and libfaac and libfaac to my ears at least sounded better, using the same settings "-ac 2 -ab 128k" built in acc had a sort of echo quality that didnt sound good.This below is just a guess, so please verify it yourself: the kdenlive h.264 rendering profile with AAC sound uses acodec=libfaac, whereas you verified that acodec=aac (built-in encoder?) is working.
Initially i tried just compiling svn ffmpeg again and compiling svn kdenlive (0.7.7) from source aac was listed in the H.264 profiles but i got the error that the codec was not recognized meaning even though via normal ffmpeg i could invoke the built in aac encoder with "acodec aac" and have it encode kdenlive just didnt see it.įinally the built in encoder needs work or you need a different set of settings to make the encoded files sound nice, i did a test between that and libfaac and libfaac to my ears at least sounded better, using the same settings "-ac 2 -ab 128k" built in acc had a sort of echo quality that didnt sound good.I haven't personally compared the quality of the native AAC encoder and libfaac, but some people have told me that it usually doesn't sound as good as libfaac, and then others say that libfaac doesn't sound as good as neroaacenc. Seems ffmpeg-extra will definitely replace some libraries i built/installed myself in particular libx264 with the repo version sure i can overwrite it by installing it again but you can never tell what conflict you might run into. Argh, they should really have a clear tutorial on building individual libraries yourself.
