Mathieu Duponchelle	9e8d1dccb4	ccconverter: add support for advertising / selecting field ... Raw 608 caps can now contain a "field" field. On the input side it signifies that the input raw 608 is attached to either field 0 or 1, on the output side it allows selecting whether to extract the raw 608 data for field 0 or 1 for field-aware formats. In addition, it is also allowed to use ccconverter to "convert" 608 field 0 to 608 field 1 (and conversely), this is passthrough as the change only needs to happen in the caps.

Matthew Waters	088597b430	closedcaption: move CC buffering to helper object ... Move most of the interesting code from ccconverter to this new helper object. Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/3211>	2022-11-10 00:52:14 +00:00
Matthew Waters	741cfd18b5	ccconverter: drop data when overflow on extracting cea608 from cc_data ... If the buffer overflows, then drop rather than causing a failure and fropping the output buffer indefinitely. This may have caused downstream to be waiting for data the will never arrive.

Matthew Waters	542060fea7	ccconverter: fix framerate passthrough with malformed input ... If an input is malformed (only produces cea608 field 1 cc_data) then when in passthrough we would effectively be dropping every second cea608 on output as we would not store any unused cea608 data. Fix by having all code paths go through the framerate conversion code which will store and retrieve any relevant data across buffers.

Matthew Waters	2e69886a02	ccconverter: ensure correct ordering of cea608 across output buffers ... e.g. if a 60fps output is configured, we can only produce a single field of cea608 that must alternate between field 1 and field 2.

Matthew Waters	6977119f99	ccconverter: ignore padding cea608 data even if marked as 'valid' ... Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/2019>	2022-03-26 00:00:36 +00:00
