Other interesting software

How to convert any format to H264 (html5) video using ffmpeg ? [on hold]
14 juillet 2013, par kheyaI am trying to use a single command to convert avi, mov, wmv etc to H264 (HTML5 playback)
I have command that converted the avi correctly to H264 (created .mp4 file)
But the same command fails to convert a quicktime mov file.I am using the 64bit static built on windows.
Here is the command I used to convert AVI to H264. This one works.
for %%a in ("*.avi") do (
ffmpeg -i "%%a" -c:v libx264 -preset slow -crf 20 -c:a libvo_aacenc -b:a 128k "%%~na.mp4"
)I am trying this to convert mov to H264 :
for %%a in ("*.mov") do (
ffmpeg -i "%%a" -vcodec mpeg4 -acodec libvo_aacenc "%%~na.mp4" //fails
ffmpeg -i "%%a" -vcodec libx264 -vprofile high -preset slow -b:v 500k -maxrate 500k -bufsize 1000k -vf scale=-1:480 -threads 0 -acodec libvo_aacenc -b:a 128k "%%~na.mp4" //fails with error )Appreciate if you kindly help me.
EDIT :
Here is the error :

FFMPEG compiling on heroku
17 juillet 2013, par JanI have a Rails app running in heroku.
I wanna watermark an original AUDIO-file with another AUDIO-file through a merging/mixing (amerge or amix) filter. Also fades and looping should work.
FFMPEG must be compiled for this feature to run on heroku.
My steps I got from this GIST which uses Vuclanhttps://gist.github.com/liufengyun/5055354
Locally I use the following term to convert with Carrierwave which is an uploader :
"-i Original.aiff -i public/watermark/#{ENV['WATERMARK_FILENAME']}.aiff -loop 1 -filter_complex '[1]afade=t=in:ss=0:d=1[4];[4]afade=t=out:st=#{self.evaluate_length-2}:d=2[5];[5][0]amix=duration=shortest[out]' -map [out]"
This works with the ffmpeg built in on my mac.
My compiled version for heroku does contain amerge, amix and the libavformat library.
This is the log which I got from heroku when I go to my upload form and uplaod a file :
