* avformat/utils: Use static mutexes instead of ff_lock_avformat()Andreas Rheinhardt2024-05-201-5/+7
| | | | | | | | | Its existence is a remnant of (libavcodec's) lock-manager API which has been removed in a04c2c707de2ce850f79870e84ac9d7ec7aa9143. There is no need to use the same lock for avisynth, chromaprint or tls, so switch to ordinary static mutexes instead. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avformat: Make init function out of write_header functions if possibleAndreas Rheinhardt2024-03-221-2/+2
| | | | | | Also mark them as av_cold while just at it. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avformat: Enforce codec_id where appropriateAndreas Rheinhardt2024-03-221-1/+2
| | | | | | | | | | E.g. chromaprint expects to be fed 16bit signed PCM in native endianness, yet there was no check for this. Similarly for other muxers. Use the new FF_OFMT_FLAG_ONLY_DEFAULT_CODECS to enfore this where appropriate, e.g. for pcm/raw muxers. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avformat/mux: Add flag for "not more than one stream of each type"Andreas Rheinhardt2024-03-221-5/+3
| | | | | | | | | | | | | | | | More exactly: Not more than one stream of each type for which a default codec (i.e. AVOutputFormat.(audio|video|subtitle)_codec) is set; for those types for which no such codec is set (or for which no designated default codec in AVOutputFormat exists at all) no streams are permitted. Given that with this flag set the default codecs become more important, they are now set explicitly to AV_CODEC_ID_NONE for "unset"; the earlier code relied on AV_CODEC_ID_NONE being equal to zero, so that default static initialization set it accordingly; but this is not how one is supposed to use an enum.

* all: use designated initializers for AVOption.unitAnton Khirnov2024-02-141-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | Makes it robust against adding fields before it, which will be useful in following commits. Majority of the patch generated by the following Coccinelle script: @@ typedef AVOption; identifier arr_name; initializer list il; initializer list[8] il1; expression tail; @@ AVOption arr_name[] = { il, { il1, - tail + .unit = tail }, ... }; with some manual changes, as the script: * has trouble with options defined inside macros * sometimes does not handle options under an #else branch * sometimes swallows whitespace
* Revert "all: Don't set AVClass.item_name to its default value"Anton Khirnov2024-01-201-0/+1
| | | | | | | Some callers assume that item_name is always set, so this may be considered an API break. This reverts commit 0c6203c97a99f69dbaa6e4011d48c331e1111f5e.
* all: Don't set AVClass.item_name to its default valueAndreas Rheinhardt2023-12-221-1/+0
| | | | | | | | Unnecessary since acf63d5350adeae551d412db699f8ca03f7e76b9; also avoids relocations. Reviewed-by: Anton Khirnov <anton@khirnov.net> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avformat/avformat: Move AVOutputFormat internals out of public headerAndreas Rheinhardt2023-02-091-6/+7
| | | | | | | | | | | | | | 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).

* lavf/chromaprint: Silence compilation warningsCarl Eugen Hoyos2020-04-051-3/+4
| | | | | | | Fixes the following warnings: libavformat/chromaprint.c:117:42: warning: passing argument 2 of ‘chromaprint_feed’ from incompatible pointer type libavformat/chromaprint.c:132:52: warning: passing argument 2 of ‘chromaprint_get_raw_fingerprint’ from incompatible pointer type libavformat/chromaprint.c:143:71: warning: passing argument 4 of ‘chromaprint_encode_fingerprint’ from incompatible pointer type
* avformat/chromaprint: Fix writing raw fingerprintAndriy Gelman2019-10-161-1/+1
| | | | | | | | | The pointer fp after the call to chromaprint_get_raw_fingerpoint() points to an array of uint32_t whereas the current code assumed just a char stream. Thus when writing the raw fingerprint, the output would be truncated by a factor of 4. For reference the declaration of the function from chromaprint.h is: int chromaprint_get_raw_fingerprint(ChromaprintContext *ctx, uint32_t **fingerprint, int *size);
* avformat/chromaprint: improve logging messageAndriy Gelman2019-10-141-1/+1
| | | | Setting silence_threshold requires that -algorithm is set to 3.
* avformat/chromaprint: Fix fp_format optionAndriy Gelman2019-10-141-1/+1
| | | | | The fp_format option was incorrectly declared, so it could not be set via string constants.
* lavc, lavf: move avformat static mutex from avcodec to avformatwm42017-12-261-4/+5
| | | | | | | | It's completely absurd that libavcodec would care about libavformat locking, but it was there because the lock manager was in libavcodec. This is more stright forward. Changes ABI, but we don't require ABI compatibility currently.
