* avcodec/pgssubdec: Mark decoder as init-threadsafeAndreas Rheinhardt2021-05-02
| | | | Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
* avcodec: Constify AVCodecsAndreas Rheinhardt2021-04-27
| | | | | | | | | | Given that the AVCodec.next pointer has now been removed, most of the AVCodecs are not modified at all any more and can therefore be made const (as this patch does); the only exceptions are the very few codecs for external libraries that have a init_static_data callback.

| | | | | | | | | | | | | | | | | | Widen the values from limited to full range and use BT.709 where it should be used according to the video resolution: SD is BT.601, HD is BT.709 Default to BT.709 due to most observed HDMV content being HD.

* | pgssubdec: fix subpicture output colorspace and rangeJan Ekström2016-04-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Functionality used before didn't widen the values from limited to full range. Additionally, now the decoder uses BT.709 where it should be used according to the video resolution. Default for not yet set colorimetry is BT.709 due to most observed HDMV content being HD. BT.709 coefficients were gathered from the first two parts of BT.709 to BT.2020 conversion guide in ARIB STD-B62 (Pt. 1, Chapter 6.2.2). They were additionally confirmed by manually calculating values. Fixes #4637

| * lavc: Add data and linesize to AVSubtitleRectVittorio Giovara2015-10-21
| | | | | | | | | | | | | | | | | | | | | | | | Use the new fields directly instead of the ones from AVPicture. This removes a layer of indirection which serves no pratical purpose whatsoever, and will help in removing AVPicture structure completely later. Every subtitle encoder/decoder seamlessly points to the new arrays, so it is possible to deprecate AVSubtitleRect.pict. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>
