  • ffmpeg : Image2 => Error while opening encoder

    29 mai 2019, par user1844282

    I get the following error ffmpeg.

    Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height

    ffmpeg -f image2 -i %05d.jpg -vcodec libx264 foo.mp4

    I’m pretty sure I’ve used this exact command before and it’s been fine. This is my terminal output. Any help would be appreciated.

  • Panning all audio channels center in ffmpeg ?

    7 mai 2012, par dcoffey3296

    I am using FFMPEG to transcode a large file to a smaller file. Usually the files will have 2 audio channels (though not always). I am trying to center all audio channels.

    I asked over at the ffmpeg-users for examples of how to do this : http://ffmpeg-users.933282.n4.nabble.com/Panning-audio-channels-example-td4417939.html

    What I got from the replies is that FFMPEG has yet to implement audio filters. Somehow I should be able to set up a libav filter (?) to pan all channels center... something to the effect of :
    pan="c0=0.5*FL+0.5*FR" though when I do this, I get the error : No such filter: 'pan'. Those guys are great but I can't figure this out by reading the docs.

    I have not disabled filters, here is my build info
    configuration: --prefix=/opt/local --enable-gpl --enable-postproc --enable-swscale --enable-avfilter --enable-libmp3lame --enable-libvorbis --enable-libtheora --enable-libdirac --enable-libschroedinger --enable-libopenjpeg --enable-libxvid --enable-libx264 --enable-libvpx --enable-libspeex --mandir=/opt/local/share/man --enable-shared --enable-pthreads --cc=/opt/local/bin/gcc-apple-4.2 --arch=x86_64 --enable-yasm --enable-nonfree --enable-libfaac

    Here is an example of one of my built command lines : ffmpeg -i inMovie.mov -acodec libfaac -ab 64k -vcodec libx264 -vpre medium -b 320k -pass 1 -s 374x210 -threads 0 outMov.mp4

    I've got the rest of my FFMPEG command line working great... Essentially what I am looking for is to have left/right audio channels both have the same audio in the output file. If there is an easier way to do this (convert to 2 mixed mono channels ?) I am all ears !!

    Thank you for your help !
