* avformat/internal: Move FF_FMT_INIT_CLEANUP to demux.hAndreas Rheinhardt2024-03-261-1/+1
| | | | | | | | | and rename it to FF_INFMT_INIT_CLEANUP. This flag is demuxer-only, so this is the more appropriate place for it. This does not preclude adding internal flags common to both demuxer and muxer in the future. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avformat/avformat: Add FFInputFormat, hide internals of AVInputFormatAndreas Rheinhardt2024-03-071-4/+5
| | | | | | | | | | | | | | | | | | | | | This commit does for AVInputFormat what commit 59c9dc82f450638a3068deeb1db5c56f6d155752 did for AVOutputFormat: It adds a new type FFInputFormat, moves all the internals of AVInputFormat to it and adds a now reduced AVInputFormat as first member. This does not affect/improve extensibility of both public or private fields for demuxers (it is still a mess due to lavd). This is possible since 50f34172e0cca2cabc5836308ec66dbf93f5f2a3 (which removed the last usage of an internal field of AVInputFormat in fftools). (Hint: tools/probetest.c accesses the internals of FFInputFormat as well, but given that it is a testing tool this is not considered a problem.)

* subviewer: sanitize packets.Clément Bœsch2013-01-031-12/+23
| | | | | | | | The data does not contain timing or trailing line breaks anymore. In addition to being less idiotic, it is consistent with other codecs and thus allows more switches between formats and codecs. It also fixes the issue of the trailing line returns being simple \n instead of CRLF in the ASS rectangle dialogue (this is the reason of the FATE update).
* lavf: remove generic index flag from text subtitles.Clément Bœsch2013-01-021-1/+0
| | | | This flag is not necessary.
* 10l: export ff_bprint_to_extradata between libs using avpriv_ prefix.Clément Bœsch2012-12-301-1/+1
| | | | Both libavformat and libavcodec requires this function.
* lavc: add ff_bprint_to_extradata() helper and use it.Clément Bœsch2012-12-301-5/+3
| | | | | | | | | | This commit also makes sure the extradata and subtitle_header are NUL terminated, without taking into account the trailing '\0' in account in the size. At the same time, it should fix 'warning: dereferencing type-punned pointer will break strict-aliasing rules' warning for compilers who don't consider uint8_t** and char** compatibles.
