Question

i have a script which uses this ffmpeg command’s parameters for encoding videos.

ffmpeg -i inputfile -acodec libfaac -keyint_min 20 -r 20 -vcodec libx264 -vpre hq -crf 25 -b 300k -bt 300k -y -v 0 -bf 16 -threads 0 outputfile

and i have a custom command i would like to add to it, is like this

ffmpeg -i inputfile -vf "movie=watermark.png [watermark]; [in][watermark] overlay=main_w-overlay_w-10:main_h-overlay_h-10 [out]" outputfile

so i replaced main command like this

 ffmpeg -i inputfile -acodec libfaac -keyint_min 20 -r 20 -vcodec libx264 -vpre hq -crf 25 -b 300k -bt 300k -y -v 0 -bf 16 -threads 0 -vf "movie=watermark1.png [watermark]; [in][watermark] overlay=main_w-overlay_w-10:main_h-overlay_h-10 [out]" outputfile

and tried it in command line, but this doesnt do anything, the output is nothing like this

[root@www test1]#  ffmpeg -i test1800.mp4 -acodec libfaac -keyint_min 20 -r 20 -vcodec libx264 -vpre hq -crf 25 -b 300k -bt 300k -y -v 0 -bf 16 -threads 0 -vf "movie=watermark1.png [watermark]; [in][watermark] overlay=main_w-overlay_w-10:main_h-overlay_h-10 [out]" outputfile.mp4
[root@www test1]#

how do i solve this ?

Thanks for your time.

Use -h to get full help or, even better, run 'man ffmpeg'

Your build of ffmpeg must be very old if you’re using -vpre with libx264. Also, -crf and -b are mutually exclusive so you can either use one or the other, but not both which will result in ffmpeg ignoring one of the options.

This example is an approximation of your command, but with recent syntax:

ffmpeg -i input -i watermark.png -c:v libx264 -preset slow -crf 25 -c:a libfaac -q:a 100 -filter_complex "overlay=main_w-overlay_w-10:main_h-overlay_h-10" output.mp4

If you are too lazy to compile see the ffmpeg.org download page for links to Linux, Windows, or OS X builds. Note that libfaac will probably not be available with third-party builds, but other AAC encoders such as libvo_aacenc may be available–and most certainly the native encoder aac is always an option.

See the FFmpeg and x264 Encoding Guide for more details.

Some things to remember for next time:

• ffmpeg usage questions are better suited for superuser.com. Stack Overflow is specifically targeted for programming questions and answers.

• This is a common problem, but instead of saying, “this doesnt do anything” please show the complete ffmpeg console output that results from your ffmpeg command. It contains more useful information than simply stating “this doesnt do anything”.

• Try to use a recent version of ffmpeg when possible. Development is very active and any encountered bugs have a good chance of already being fixed.
