Video shearing

[BlahUser]

Hello,

On some videos that I created using ffmpeg from a series of static pictures, the image is always sheared. It plays fine in other players (quicktime etc)
I have had this happen for lots of different videos, it is not isolated.

ffmpeg -r 10 -b 1800 -i Frame%d.png test1800.mp4

I am using 0.8.6d Janus

Does anyone know what is causing this, or how to resolve this issue. I am happy to post the offending video or a screenshot somewhere if it helps

Thankyou

Hello,

I have posted an example video and screenshot here:

Apologies for the terrible hosting service If any more information is needed let me know what to do!

Output from running VLC from the command line then using the menu to navigate to the file, with verbose (level 2) output:

Update:

Last time i was using macOSX 10.4 with x86; this time its on a powerbook G4 (Grishenko 0.9. -- I have uploaded new screenshots and a video sample (links below). With the same file the error doesn't happen under debian lenny.
