* avformat/mux: Store pointer to interleavement func in FFFormatContextAndreas Rheinhardt2021-11-19
| | | | | | | It avoids branches lateron and will allow to easily avoid the overhead of the linked list currently in use in case there is only one stream. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avformat/utils: Remove unused shorthand feature for auto-inserted BSFAndreas Rheinhardt2021-11-18
| | | | | | | | Besides being unused it should not be used at all: The order of options of bitstream filters is not guaranteed to be stable at all. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avformat/mxfenc: Make init function out of write_headerAndreas Rheinhardt2021-11-18
| | | | | | | | | The MXF muxers only write the header after they have received a packet; the actual write_header function does not write anything. So make an init function out of it. Reviewed-by: Tomas Härdin <tjoppen@acc.umu.se> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avformat/mxfenc: Remove redundant checkAndreas Rheinhardt2021-11-18
| | | | | | | | None of the muxers here has the AVFMT_NOSTREAMS flag set, so it is checked generically that there are streams. Reviewed-by: Tomas Härdin <tjoppen@acc.umu.se> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avformat/hlsenc: Only write something if there is something to writeAndreas Rheinhardt2021-11-18
| | | | | | | | | | This is especially important in case avio_write() would be switched to an unsigned type like size_t, then a potential error from avio_read() (with negative return value) would no longer be handled gracefully by avio_write().

* avformat/hlsenc: Remove nonsense memsetAndreas Rheinhardt2021-11-18
| | | | | | | | | | | The memset here is both unnecessary (avio_read() ignores the previous content of the destination buffer) as well as nonsense (for a char buf[BUFSIZE] sizeof(buf) and sizeof(BUFSIZE) are not the same; the latter is sizeof(int)).

* avformat/http: Add short_seek_size optionDerek Buitenhuis2021-11-17
| | | | | | | | | | | | | | | In 45bfe8b838275235412777dd430206d9a24eb3ee, short_seek_threshold was removed from the public AVIO struct. Although this option was private and not intended to be used by public API users, it was nonetheless, because it provided functionality that could otherwise not be gained via public API. This was especially important for networked I/O like HTTP, where the internal size for lavf could be way to small depending on the specifics of a user's usecase, such as reading interlavd media files from cloud storage. Add an AVOption to make this functionality accessible to the HTTP client. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>
* lavf: add "disposition" AVOption to AVStream AVClassAnton Khirnov2021-11-16

* lavf: add an AVClass to AVStream on next major bumpAnton Khirnov2021-11-16
| | | | | | | Also add a function to retrieve that class, analogously to avformat_get_class(). This will be useful for adding an AVOption for dispositions.
* lavf: improve AV_DISPOSITION_* doxyAnton Khirnov2021-11-16
| | | | | Also switch the values definition to the (1 << N) style, which is easier to read.
* */version.h: define FF_API macros unconditionallyAnton Khirnov2021-11-15
| | | | | | | There is no reason to wrap them in #ifndef guards, they should only be defined here and nowhere else. The define guards just add the possibility to accidentally use the same FF_API name in different libraries.
* avformat/concatdec: fix NEEDS_UNSAFE flag valueGoogleplex2021-11-14

| | | | | | | Try to make the feature easier to use, especially since the user have enabled -strict experimental manually. The user shouldn't be surprised that hls_playlist is enabled for lhls automatically, so change the log level from warning to info for that.

* avformat/avio{,buf}: introduce public AVIOContext::bytes_{read,written}Jan Ekström2021-10-24
| | | | | | | Such fields can be seen as generally useful in cases where the API user is not implementing custom AVIO callbacks, but still would like to know if data is being read or written out, such as in case data is being read from input but no AVPacket has been received yet.
* avformat/avio{,buf}: deprecate AVIOContext::writtenJan Ekström2021-10-24
| | | | | | | | Originally added as a private entry in commit 3f75e5116b900f1428aa13041fc7d6301bf1988a, but its grouping with the comment noting its private state was missed during merging of the field from Libav (most likely due to an already existing field in between).
* avformat/avio: privatize source of truth for AVIOContext::writtenJan Ekström2021-10-24
| | | | | | | | | | | Looking at 3f75e5116b900f1428aa13041fc7d6301bf1988a, the field was supposed to be private, but during merging the field and the group that had the comment about it got separated. Thus, move the actual privately utilized state of this variable into the private FFIOContext. Additionally, name the private field somewhat better, so that it does not get confused with the amount of bytes written out.

* seek: Fix crashes in ff_seek_frame_binary if built with latest Clang 14Martin Storsjö2021-10-18
| | | | | | | | | | | | | | | | | | | | | | | | | Passing an uninitialized variable as argument to a function is undefined behaviour (UB). The compiler can assume that UB does not happen. Hence, the compiler can assume that the variables are never uninitialized when passed as argument, which means that the codepaths that initializes them must be taken. In ff_seek_frame_binary, this means that the compiler can assume that the codepaths that initialize pos_min and pos_max are taken, which means that the conditions "if (sti->index_entries)" and "if (index >= 0)" can be optimized out. Current Clang git versions (upcoming Clang 14) enabled an optimization that does this, which broke the current version of this function (which intentionally left the variables uninitialized, but silencing warnings about being uninitialized).
