#5108: png -> webm produces video with colors larger and offset
------------------------------------+--------------------------------------
Reporter: petrelharp | Type: defect
Status: new | Priority: normal
Component: ffmpeg | Version: git-master
Keywords: webm | Blocked By:
Blocking: | Reproduced by developer: 0
Analyzed by developer: 0 |
------------------------------------+--------------------------------------
Converting pngs to webm produces video where everything that's in color is
about twice as big as it should be, and about in the right place for a
video that's twice as big; something like a K channel (as in CMYK) shows
up in the right place. Conversion in the same way to mp4 does not have
this problem. This bug wasn't present in v2.6.1, but is present in
git/master, as well as in 2.8.4, the version current in debian/sid.
How to reproduce:
