Andreas Rheinhardt	6aad1204cc	avcodec: Add FF_CODEC_CAP_NOT_INIT_THREADSAFE This is in preparation of switching the default init-thread-safety to a codec being init-thread-safe. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	2 years ago
Andreas Rheinhardt	6ed0d95fa2	avcodec/codec_internal: Constify AVPacket in decode_sub cb No subtitle decoder ever modifies the AVPacket given to it. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	3 years ago
Andreas Rheinhardt	4243da4ff4	avcodec/codec_internal: Use union for FFCodec decode/encode callbacks This is possible, because every given FFCodec has to implement exactly one of these. Doing so decreases sizeof(FFCodec) and therefore decreases the size of the binary. Notice that in case of position-independent code the decrease is in .data.rel.ro, so that this translates to decreased memory consumption.

Andreas Rheinhardt	fb59a42ef9	avcodec/codec_internal: Add FFCodec.decode_sub This increases type-safety by avoiding conversions from/through void. It also avoids the boilerplate "AVSubtitle sub = data;" line for subtitle decoders. Its only downside is that it increases sizeof(FFCodec), yet this can be more than offset lateron.

Andreas Rheinhardt	20f9727018	avcodec/codec_internal: Add FFCodec, hide internal part of AVCodec Up until now, codec.h contains both public and private parts of AVCodec. This exposes the internals of AVCodec to users and leads them into the temptation of actually using them and forces us to forward-declare structures and types that users can't use at all. This commit changes this by adding a new structure FFCodec to codec_internal.h that extends AVCodec, i.e. contains the public AVCodec as first member; the private fields of AVCodec are moved to this structure, leaving codec.h clean.

Andreas Rheinhardt	a247ac640d	avcodec: Constify AVCodecs 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.

Jan Ekström	4beccf400d	lavc/libaribb24: add error handling to region handling Fixes some rather embarrassing mistakes that somehow passed my eyes. * Now catches if memory allocation has failed during bprint usage by checking av_bprint_is_complete(). * Now catches if adding an ASS rectangle into an AVSubtitle failed. * Returns AVERROR_INVALIDDATA if we get an invalid region buffer length.	6 years ago
Jan Ekström	100bfac6d6	add libaribb24 ARIB STD-B24 caption decoder * Outputs ASS lines with basic coloring and font scaling for each given region. * Sets the default style to the resolution of the subtitle plane (for example, 960x540 / 36pt font for profile A). * Has options to: * Disable ruby text (which is coded as regions which have half-height text in libaribb24). Enabled by default as without positioning ruby text only confuses as it is usually coded in the beginning of the decoded subtitle line. * Set the working directory, in which libaribb24 will read configuration as well as into which it may save broadcast extra symbols as PNG. Unset by default. The unconventional library check can be explained by the library's current master branch being licensed as LGPLv3, but at the time of writing the latest official release is still licensed under GPLv3. Thus, one either has to wait for the following release, or enable GPLv3.	6 years ago
