Anton Khirnov aae5ba31ca lavf/dv: shorten code by using a local variable 2023-05-02 10:57:21 +02:00
Anton Khirnov c7a852b638 lavf/dv: do not set video timebase more than once 
Current code will call avpriv_set_pts_info() for each video frame,
possibly setting a different timebase if the stream framerate changes.
This violates API conventions, as the timebase is supposed to stay
constant after stream creation.

Change the demuxer to set a single timebase that is fine enough to
handle all supported DV framerates.

The seek tests change slightly because the new timebase is more
granular.

Niklas Haas e3143703e9 avfilter/vf_libplacebo: strip ICC profiles on CSP change 
Not doing so is an obvious oversight - the ICC profile is tied to the
original colorspace, so if we change it, we should definitely strip this
information.

We should probably also have an extra option to control whether the ICC
profile should be stripped, ignored, or applied, but for now this fixes
an existing bug.

Niklas Haas 54126920fc doc/filters/libplacebo: add vaapi interop example 
Some testing revealed this to be a very efficient and reliable method of
ingesting GPU frames into libplacebo, so it's a good idea to give as an
example.
 2023-04-26 15:36:10 +02:00
Niklas Haas 4fa691b761 doc/filters/libplacebo: remove outdated example 
This example being first is now misleading because round-tripping
through hwdownload/hwupload is neither required nor recommended. Also,
the comment about avoiding format conversion is unnecessary because
`libplacebo` will now inherit the input frame format by default.

Derek Buitenhuis f7d64881f8 mov: Do not blindly disable advanced edit lists if use_mfra_for is set 
This was a bug/mistake in dae3679a9b.

use_mfra_for by defintion only has an effect on fragmented MP4 files,
making the check not only redundant, but also broken if a user used
the option globally (i.e. set on non-fragmented MP4s).
