ffmpeg error message

[semperlinux]

Hi Forum,

I have an mp4 video clip that I'd like to compress to get it under the 100MB size limit - then I'll be able to upload it to my vShare website.

I get the following error message :- [mpeg4 @ 0x12621a0] Invalid pixel aspect ratio 65536/65536, limit is 255/255.

An output .mp4 file is generated but has no content.

The following is terminal o/p..................

I would try a different binary, although it's only a couple of months old, this build has a depreciated warning

> Invalid pixel aspect ratio 65536/65536, limit is 255/255.
-> you could try if it helps to specify the aspect ratio with:
-aspect 1:1

[semperlinux]

Poisondeathray :-
I read in several places that the 'deprecation' notice is there because Ubuntu have stopped using it - ffmpeg is apparently still being developed / maintained. This however must be an Ubuntu package version as it contains the deprecation notice.
I don't think there's anything wrong with this version - i.e. the problem isn't being caused by software failure.


Selur :-
Using your 'aspect' command produced a different error as follows...........
[mpeg4 @ 0x7c81a0] timebase 1/90000 not supported by MPEG 4 standard, the maximum admitted value for the timebase denominator is 65535

The remainder of the text o/p is identical to the original error.


Thanks for the input.

timebase 1/90000 not supported by MPEG 4 standard,

-> also specify the input frame rate e.g. -r 23.967
