Version 6.26.1
This version fixes a major regression in the avformat producer to read from
network URLs.
Version 6.26.0
This is the last planned release of major version 6. Version 7 will be released
soon and introduce some minor API breakage while removing deprecations.
The main new feature in this version is hardware-accellerated decoding!
However, this is a basic implementation: It always returns the uncompressed
video to the CPU memory with no pipelining to filters. Even when coupled with
hardware encoding in the avformat consumer it must transfer the video. Also,
there is no automatic software/CPU fallback and no resource management.
Modules
* Added support for `hwaccel` query string parameter to the `avformat`
producer. It accepts the following values:
vaapi (Linux/BSD), cuda (Linux), videotoolbox (macOS), d3d11va (Windows), dxva2 (Windows)
* Added support for `hwaccel_device` query string parameter to the `avformat`
producer. This is only used with vaapi (device path) and cuda, d3d11va, or
dxva (number).
* Improved the usage of image slice threading in `frei0r`. This only applies
when `threads`=0 and only works with some frei0r plugins that you must decide
yourself.
* Added an ellipse item to `kdenlivetitle` producer.
* Added support for PNG and GIF as album art in the `avformat` producer.
* Added BT.2020 color space metadata to the `avformat` producer.
* Resolved many FFmpeg deprecations in the `avformat` producer making it possible to support AV1 decoding.
* Added a `strobe` fitler that periodically makes the alpha channel transparent.
* Added a new `typewriter` text filter (currently only works with the
kdenlivetitle producer).
* Improved sound quality for lower pitch shifts in `rbpitch`.
* Fixed speed of trick play in the `jack`, `rtaudio`, `sdl_audio`, and `sdl2_audio` consumers.
* Fixed matrix for independent channels in `swresample` filter.
* Fixed leading zeros for the `timer` filter.
