Hi,  
When I try to use the ‘video/encode’ robot to transcode a video to h.364 with aac audio using the libx264 video codec and the libaafc audio codec I always get an error message once the file has finished uploading. You can view the error message at [http://api2.adia.transloadit.com/assemblies/REDACTED](http://api2.adia.transloadit.com/assemblies/REDACTED).

It is: {

Is this my problem - due to giving ffmpeg bad settings or is it a problem at your end?

Thanks a lot guys.

Hey there Jamie,

we hope you had a merry christmas.

I looked into your problem and found out that ffmpeg complained about two parameters, spitting out the following errors:

1. Unrecognized option ‘me’
2. Unable to parse option value “brdo+mixed\_refs+dct8x8+fastpskip”: undefined constant or missing (  
Invalid value ‘+bpyramid+wpred+brdo+mixed\_refs+dct8x8+fastpskip’ for option ‘flags2’  
",

Sorry, but we currently do not support the motion estimation option. I am not sure though what caused the second error, we are still investigating on that and will get back to you. When I remove both parameters, however, ffmpeg is saying that it can’t find a suitable output format, so that doesn’t help either.

Maybe you want to tell us what kind of encoding you want to achieve? We might be able to provide you with a suitable template for it. 🙂

Kind regards,  
Tim

Hi Tim,

Thanks for the quick reply!

I’ve never used FFmpeg before which may explain all the errors, my settings were - ashamedly - copied and pasted from a friends settings. ☹

Anyway, I’m trying to set it so it transcodes any uploaded video to the h.264 codec with aac audio in an mp4 file if that’s any help?

Thanks a lot,  
Jamie
