Help to resolve FFMPEG Unrecognized option 'preset' “ error

Looking for help to resolve FFMPEG Unrecognized option 'preset' “ error

[poisondeathray]

Post some background information, and the command line used

[chrisj]

My web host upgraded FFMPEG to version SVN-r26402, and after uploading a video, via the web site, I get this error Unrecognized option 'preset' “ error,
and am told that "it appears that the version of FFMPEG that is installed, does not use the "preset" flag". So, I'm looking for a solution.

You must rewrite the ffmpeg command then....or tell your webhost to update ffmpeg.

What is the ffmpeg command? Are you using some ffmpeg script/code?

[chrisj]

Thanks for your reply.
Yes it is a convertor mod script.
The line, I believe, is:
$cmd = "$config[path_to_ffmpeg] -i $raw_video_path -vf 'movie=watermark.png [watermark]; [in][watermark] overlay=main_w-overlay_w-10:10 [out]' -strict -2 -preset medium -vcodec libx264 -acodec aac -ab 64k -ar $ffmpeg_audio_rate -b:v $bit_rate -r $frame_rate -nr 1000 -g 500 -y -s $ffmpeg_size $new_mp4";

You could start by removing -preset medium and see what happens.

[chrisj]

Thanks for your reply.
I removed -preset medium, uploaded another video file and then looked at the convertor log and see this:

Unrecognized option 'b:v'

The convertor code also has one other line relating to preset and that is this:

// createMP4("$raw_video_path","$file_name_no_extensi on","$conv_presets",3,"$file_name_no_extension".ti me());

Any help will be appreciated

-b:v is for newer ffmpeg syntax for "video bitrate" (ffmpeg binaries within the last couple of years), you're probably using very old ffmpeg build . Replace it with -b $bit_rate , or -bitrate $bit_rate, or ask the web hoster to update the ffmpeg build

[chrisj]

Thanks a lot for your reply.

Just to clarify, my web host upgraded FFMPEG to version SVN-r26402, but you're saying "ffmpeg build" is something else?

And when you say "Replace it with -b $bit_rate , or -bitrate $bit_rate", can you clarify what "it" means, please?

Thanks

SVN-r26402 is a few years old, not really an "upgrade"

2011-01-19 = over 3 years old. That is a few lifetimes in terms of ffmpeg development . Changes and updates occur frequently and fast . Officially, SVN isn't even supported anymore, they moved to a different system GIT

And when you say "Replace it with -b $bit_rate , or -bitrate $bit_rate", can you clarify what "it" means, please?

"it" means "-b:v" . Notice -b:v is replaced by -b

$cmd = "$config[path_to_ffmpeg] -i $raw_video_path -vf 'movie=watermark.png [watermark]; [in][watermark] overlay=main_w-overlay_w-10:10 [out]' -strict -2 -vcodec libx264 -acodec aac -ab 64k -ar $ffmpeg_audio_rate -b $bit_rate -r $frame_rate -nr 1000 -g 500 -y -s $ffmpeg_size $new_mp4";

[chrisj]

Much thanks again for your reply.

My web host sent me this:

[root@host3 ~]# ffmpeg -version
FFmpeg version SVN-r26402, Copyright (c) 2000-2011 the FFmpeg developers
built on May 6 2014 12:42:26 with gcc 4.1.2 20080704 (Red Hat 4.1.2-54)

I'm not that technical, but doesn't this show a recent build?

Also, just to be clear, are you suggesting that I replace, in the script, -b:v with -b ?

Thanks again

[poisondeathray]

It means that ffmpeg binary was built on May 6, 2014, but based on libraries that are old .

The analogy would be you have blue prints for a "Ford Model T" car circa ~1910 , and build that clunker on May 6, 2014 . It's ancient by today's standards. That's why none of the modern syntax work (those old builds are using an old libx264 snapshot, probably predated the presets)

Yes, you replace -b:v with -b , or -bitrate , and you remove -preset medium

[chrisj]

Thanks again.
I have sent a message to my web host.
In the meantime I change the -b:v to -b
And the command line looks like this now:
$cmd = "$config[path_to_ffmpeg] -i $raw_video_path -vf 'movie=watermark.png [watermark]; [in][watermark] overlay=main_w-overlay_w-10:10 [out]' -strict -2 -vcodec libx264 -acodec aac -ab 64k -ar $ffmpeg_audio_rate -b $bit_rate -r $frame_rate -nr 1000 -g 500 -y -s $ffmpeg_size $new_mp4";

And I got an error, and the log looks like this:
[buffer @ 0xa5cd580] w:200 h:110 pixfmt:yuv420p
No such filter: 'movie'
Error opening filters!

Any additional help will be appreciated

[poisondeathray]

They probably didn't have -vf filters back then . Or at the very least, it was very rudimentary compared to the filters today. You probably can't do your watermark unless you / they update the ffmpeg build


This part is responsible for the watermark/overlay , you can remove that , or ask them to update the ffmpeg build if the watermark is important

-vf 'movie=watermark.png [watermark]; [in][watermark] overlay=main_w-overlay_w-10:10 [out]'
