Marth64	3525544e48	libavformat: add RCWT closed caption muxex Signed-off-by: Marth64 <marth64@proxyid.net> Raw Captions With Time (RCWT) is a format native to ccextractor, a commonly used open source tool for processing 608/708 closed caption (CC) sources. It can be used to archive the original, raw CC bitstream and to produce a source file file for later CC processing or conversion. As a result, it also allows for interopability with ccextractor for processing CC data extracted via ffmpeg. The format is simple to parse and can be used to retain all lines and variants of CC. A free specification of RCWT can be found here: https://github.com/CCExtractor/ccextractor/blob/master/docs/BINARY_FILE_FORMAT.TXT This muxer implements the specification as of 01/05/2024, which has been stable and unchanged for 10 years as of this writing. This muxer will have some nuances from the way that ccextractor muxes RCWT. No compatibility issues when processing the output with ccextractor have been observed as a result of this so far, but mileage may vary and outputs will not be a bit-exact match. Specifically, the differences are: (1) This muxer will identify as "FF" as the writing program identifier, so as to be honest about the output's origin. (2) ffmpeg's MPEG-1/2, H264, HEVC, etc. decoders extract closed captioning data differently than ccextractor from embedded SEI/user data. For example, DVD captioning bytes will be translated to ATSC A53 format. This allows ffmpeg to handle 608/708 in a consistant way downstream. This is a lossless conversion and the meaningful data is retained. (3) This muxer will not alter the extracted data except to remove invalid packets in between valid CC blocks. On the other hand, ccextractor will by default remove mid-stream padding, and add padding at the end of the stream (in order to convey the end time of the source video).	12 months ago

Niklas Haas	5e751dabc5	doc/APIchanges: document newly added buffersrc field This was accidentally removed in a prior revision of the series, alongside the corresponding (separate) version bump. Instead coalesce it into the follow-up commit's entry, since that's the lowest version actually supporting the new fields.	1 year ago

Niklas Haas	2d555dc82d	avfilter/buffersrc: add color_space/range parameters To allow adding proper negotiation, in particular, to fftools. These values will simply be negotiated downstream for YUV formats, and ignored otherwise.	1 year ago
Niklas Haas	8c7934f73a	avfilter: add negotiation API for color space/range Motivated by YUVJ removal. This change will allow full negotiation between color ranges and matrices as needed. By default, all ranges and matrices are marked as supported. Because grayscale formats are currently handled very inconsistently (and in particular, assumed as forced full-range by swscale), we exclude them from negotiation altogether for the time being, to get this API merged. After filter negotiation is available, we can relax the grayscale-is-forced-jpeg restriction again, when it will be more feasible to do so without breaking a million test cases. Note that this commit updates one FATE test as a consequence of the sanity fallback for non-YUV formats. In particular, the test case now writes rgb24(pc, gbr/unspecified/unspecified) to the matroska file, instead of rgb24(unspecified/unspecified/unspecified) as before.	1 year ago
