Padding to odd/uneven size fails

Reported by: agowad Owned by:
Priority: normal Component: avfilter
Version: git-master Keywords: pad
Cc: Blocked By:
Blocking: Reproduced by developer: yes

Description (last modified by cehoyos)

### 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.

  • Component changed from undetermined to avfilter
  • Keywords padding removed
  • Reproduced by developer set
  • Status changed from new to open
  • Summary changed from Scaling and padding to odd/uneven size fails to Padding to odd/uneven size fails

videofilter pad does not accept odd size values, I don't think this is documented.

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 follow-up: Changed 5 years ago by richardpl

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.

comment:7 in reply to: ↑ 6 Changed 5 years ago by cehoyos

Replying to richardpl:

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

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.

Note: See TracTickets for help on using tickets.
