Bug ID: 752802
Summary: avviddec: Sends incorrect CAPS event before the
correct one
Classification: Platform
Product: GStreamer
Version: git master
OS: Linux
Status: NEW
Severity: blocker
Priority: Normal
Component: gst-libav
Assignee: gstreamer-bugs at lists.freedesktop.org
Reporter: olivier.crete at ocrete.ca
QA Contact: gstreamer-bugs at lists.freedesktop.org
GNOME version: ---
In gst_ffmpegviddec_get_buffer2(), the AVPicture, for some 1080p streams
contains 1088 instead of 1080 as height, So it negotiates with the wrong
format, and later rengotiates to the right one when a frame is actually
produced.
This is a regression that was introduced by 5b6c8ee8 and it's caught by a
number of gst-validate tests, using sample H1_00094_1920x1280_MTS.
This possibly also needs to be fixed in ffmpeg. Although I wonder if that size
isn't the size that needs to be allocated as a scratch buffer so if it's not
the correct allocation size instead of the final picture size.
