* avformat: Make init function out of write_header functions if possibleAndreas Rheinhardt2024-03-22
| | | | | | Also mark them as av_cold while just at it. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avformat/mux: Add flag for "only default codecs allowed"Andreas Rheinhardt2024-03-22
| | | | | | | | AVOutputFormat has default codecs for audio, video and subtitle and often these are the only codecs of this type allowed. So add a flag to AVOutputFormat so that this can be checked generically. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avformat: Enforce one-stream limit where appropriateAndreas Rheinhardt2024-03-22
| | | | | | | | | | Several muxers (e.g. pcm muxers) did not check the number of streams even though the individual streams were not recoverable from the muxed files. This commit changes this by using the FF_OFMT_MAX_ONE_OF_EACH flag where appropriate. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avformat/avformat: Add FFInputFormat, hide internals of AVInputFormatAndreas Rheinhardt2024-03-07
| | | | | | | | | | | | | | | | | | | | | 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.)

* avformat/avformat: Move AVOutputFormat internals out of public headerAndreas Rheinhardt2023-02-09
| | | | | | | | | | | | | | This commit does for AVOutputFormat what commit 20f972701806be20a77f808db332d9489343bb78 did for AVCodec: It adds a new type FFOutputFormat, moves all the internals of AVOutputFormat to it and adds a now reduced AVOutputFormat as first member. This does not affect/improve extensibility of both public or private fields for muxers (it is still a mess due to lavd).

* configure: Use a separate config_components.h header for $ALL_COMPONENTSMartin Storsjö2022-03-16
| | | | | | | | This avoids unnecessary rebuilds of most source files if only the list of enabled components has changed, but not the other properties of the build, set in config.h. Signed-off-by: Martin Storsjö <martin@martin.st>
* bit: convert to new channel layout APIAnton Khirnov2022-03-15

* avformat: Constify all muxer/demuxersAndreas Rheinhardt2021-04-27
| | | | | | | This is possible now that the next-API is gone. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com> Signed-off-by: James Almer <jamrial@gmail.com>
* avformat: Forward errors where possibleAndreas Rheinhardt2019-12-12
| | | | | | | | | | It is not uncommon to find code where the caller thinks to know better what the return value should be than the callee. E.g. something like "if (av_new_packet(pkt, size) < 0) return AVERROR(ENOMEM);". This commit changes several instances of this to instead forward the actual error.
