Padding to odd/uneven size fails

Reported by: agowad Owned by:
Priority: normal Component: avfilter
Version: git-master Keywords: pad

Description (last modified by Carl Eugen Hoyos)

### WHAT
I am try resize (scale + pad) and convert a video file to mp4 format and defined size.

### PROBLEM
When padding to odd width I face problems. Strangely, when I use even numbers then it works.

### COMMAND LINES (for two files)

  1. File "Duracell10sec_CutdowulydCDCD.wmv"

A.1 Resizing to 425x300

  • COMMAND LINE: 
    ffmpeg.exe -i "Duracell10sec_Cutdow__ulydCDCD.wmv"  -vf "scale=427:239,pad=427:300:0:30,setdar=427:300"  -y -b:v 400k -r 49.75 -ar 44100  -acodec libmp3lame -vcodec libx264 -ac 2 "Duracell10sec_Cutdow__ulydCDCD4_TMP.mp4"

The same error can be generated by shorter version of the command.

I do not see how padding for subsampled formats could work at all. In non trivial cases it needs chroma interpolation. So using yuv444p or rgb formats should be workaround.

The scale filter supports odd sizes for subsampled formats, why shouldn't the pad filter allow the same?

comment:6 by Elon Musk, 11 years ago

Your reasoning is flawed. Scale filter does not scale by itself - it use libswscale.

Non trivial padding - for example padding for 1 pixel left/above for subsampled format.

How is that related?

Non trivial padding - for example padding for 1 pixel left/above for subsampled format.

I understand that it would not (easily) work for left/top padding but that was not requested in this ticket, I am simply wondering why it shouldn't work for right/bottom padding.
Note that the original request was actually that pad should not fail if input size == output size.

comment:8 by Ivan Middleton, 5 years ago

I propose to fix this bug by having the pad filter round the output width and height up instead of down.

See my message to the devel list for more details and a patch:
