#1405 closed defect (invalid)

General errors parsing presets (invalid option 'directpred' for instance)

Reported by: klaussfreire Owned by:

Bad Version:
On git master branch, last commit at Sun Jun 3 17:40:30 2012 +0200

Happiness release from the download page (so not so happy)

Good version:

Freedom release from the download page

What I'm doing:
Trying to concatenate


Every time I try to use a preset that contains the "directpred" option, I get an error: Invalid option or argument:'directpred=3', parsed as 'directpred' = '3'.

If I comment the directpred option, I get:

[NULL @ 0x638120] [Eval @ 0x7fff6bf47810] Undefined constant or missing '(' in 'obmc'
[NULL @ 0x638120] Unable to parse option value "obmc+gmc+part+aic+umv"
[NULL @ 0x638120] Error setting option flags to value +loop+obmc+gmc+part+aic+umv.

So it seems to be general preset parsing brokenness, at least regarding libx264

Version: unspecifiedgit-master

You are asking for OBMC and GMC encoding in libx264. libx264 does not support these and indeed, there are no such features in H.264 itself. The previous version of ffmpeg indeed accepted such invalid flags silently 0.11 accepts obmc when the encoder supports it, otherwise it fails with an error message.

Ok, that accounts for the second error then. I'll try when I get a chance.

But there's still the "directpred" issue.

Resolution: invalid
Status: newclosed

libx264-hq.ffpreset was the name of an old file based preset. It appears you maybe copied this old preset from somewhere and added some additional options or parameters. FFmpeg used to use these files to emulate x264 presets, but they have been depreciated and removed for the -preset and -vprofile options. See available presets and profiles with "x264 --help".

If, for some reason, you need to overwrite a particular option (but usually not a good idea for most use cases unless you know what you're doing) then see "ffmpeg -h" for available libx264 specific options (under libx264 AVOptions) or use the -x264opts option.

ffmpeg -i input -preset medium -direct-pred 3 output
ffmpeg -i input -preset medium -x264opts direct=auto output

...and of course I meant "libx264 AVOptions", not "libx264rgb AVOptions" although the listed options are identical.

You're right, it works fine like you said.

For further reference, I couldn't make any flags2 work (so I just commented them out, I don't think they had an effect anyway), and I could fix the directpred thing in the preset by using "direct-pred=3" (with the "-")

Thanks a lot.
