* libavformat/tls_libtls: handle TLS_WANT_{POLLIN, POLLOUT} in read/write ↵Matthieu Bouron2022-06-08
| | | | | | | | | | | | | | | functions According to the tls documentation: tls_read() and tls_write() can return TLS_WANT_POLLIN and TLS_WANT_POLLOUT which indicates that the same operation must be repeated immediately. This commit prevents the libtls backend from failing when libtls returns TLS_WANT_POLLIN or TLS_WANT_POLLOUT with the following error: [tls @ 0x7f6e20005a00] (null) Signed-off-by: Marton Balint <cus@passwd.hu>
* lavf/matroskadec: stop mapping text/plain attachments to AV_CODEC_ID_TEXTAnton Khirnov2022-06-08
| | | | | | There is no reason to think that an attachment will contain text subtitles. Furthermore, attachments are exported in extradata, so the AV_CODEC_ID_TEXT decoder would not do anything useful with them anyway.
* libavformat/isom: Add more language mappingsIvan Baykalov2022-06-07

* avformat/hls, dashdec: Don't use AV_OPT flags in av_dict_set()Andreas Rheinhardt2022-05-16
| | | | | | | | | | | | | | | | | av_dict_set() expects a different set of flags, namely the AV_DICT_* flags. Using AV_OPT_FLAG_DECODING_PARAM (or any AV_OPT_FLAG_*) ic av_dict_set() is therefore completely wrong and given that av_dict_set() just doesn't care about whether the string it receives has anything to do with a decoding parameter or not, it should just be removed without replacement. (The numerical value of AV_OPT_FLAG_DECODING_PARAM currently coincides with AV_DICT_IGNORE_SUFFIX. Given that the dictionaries we are dealing with here are always empty (i.e. NULL) before the calls to av_dict_set(), this flag changes nothing. It would be different if it were equal to one of the AV_DICT_DONT_STRDUP_* values.) Reviewed-by: Jan Ekström <jeebjp@gmail.com> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/ac3: Move non-(de|en)coder-only parts out of ac3.hAndreas Rheinhardt2022-05-15
| | | | | | | | | | Move AC3HeaderInfo into ac3_parser_internal.h and the rest into a new header ac3defs.h. This also breaks an include cycle of ac3.h and ac3tab.h (the latter now only needs ac3defs.h). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avformat/movenc: Add support for AVIF muxingVignesh Venkatasubramanian2022-05-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add an AVIF muxer by re-using the existing the mov/mp4 muxer. AVIF Specification: https://aomediacodec.github.io/av1-avif Sample usage for still image: ffmpeg -i image.png -c:v libaom-av1 -still-picture 1 image.avif Sample usage for animated AVIF image: ffmpeg -i video.mp4 animated.avif We can re-use any of the AV1 encoding options that will make sense for image encoding (like bitrate, tiles, encoding speed, etc). The files generated by this muxer has been verified to be valid AVIF files by the following: 1) Displays on Chrome (both still and animated images). 2) Displays on Firefox (only still images, firefox does not support animated AVIF yet). 3) Verified to be valid by Compliance Warden: https://github.com/gpac/ComplianceWarden Fixes the encoder/muxer part of Trac Ticket #7621 Signed-off-by: Vignesh Venkatasubramanian <vigneshv@google.com>

* avformat/internal: Hide BSF stuff only used by the core APIsAndreas Rheinhardt2022-05-12
| | | | | | | | | | | | | | | | | | | | | The general demuxing API uses bitstream filters to extract extradata and the muxing API uses them in order to transform packets into the format desired by the target format. Therefore FFStream contains pointers to AVBSFContexts and lavf/internal.h includes lavc/bsf.h. Yet actually, only a few files files are supposed to use these, namely avformat.c, demux.c and mux.c. For all the other files, it should be an opaque type that they should not touch and that they need not know anything about. This can be achieved by not including these headers and using the structs instead of the corresponding typedefs. This also forces translation units that really use the BSF API themselves to include lavc/bsf.h directly instead of relying on indirect inclusions (a few other files also use the BSF API; they already abided by this). Of course, it also avoids unnecessary rebuilds when bsf.h changes. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avformat/asf: Move ASF GUIDs to a new fileAndreas Rheinhardt2022-05-10
| | | | | | | | | | | They are also needed by the MMSH and MMST protocols and therefore the file they are in is pulled in when these protocols are enabled and used. By moving them to a separate file, linking statically to libavformat while only using AVIO no longer pulls in all the muxers/demuxers (and also no longer any AVCodecs when linking statically to libavcodec).
