* avformat/id3v2: Add Grouping frame to id3v2.4 metadata tableWolfgang Müller2022-02-15
| | | | | | | | | | | | | | | | | The ID3v2.4.0 standard defines TIT1 as the "Content group description" tag [1]. This frame is usually referred to as the "Grouping" tag and in de-facto use under that name by Vorbis and APEv2 [2]. This commit introduces a mapping from "TIT1" to "grouping" in the id3v2.4 metadata conversion table. This will enable software to access it using that name. In particular, MPD will now read this tag correctly when using the ffmpeg decoder plugin.

* avisynth: use AviSynth+'s frame properties to set various fieldsStephen Hutchinson2022-02-13
| | | | | | | | | | | | | | | * Field Order * Chroma Location * Color Transfer Characteristics * Color Range * Color Primaries * Matrix Coefficients The existing TFF/BFF detection is retained as a fallback for older versions of AviSynth that can't access frame properties. The other properties have no legacy equivalent to detect them. Signed-off-by: Stephen Hutchinson <qyot27@gmail.com>
* avisynth: corrected interlace detectionemcodem2022-02-13
| | | | | | | | | | | | | | | AviSynth works on frame-based video by default, which can be either progressive or interlaced. Some filters can break frames into half-height fields, at which point it considers the clip to be field-based (avs_is_field_based can be used to check for this situation). To properly detect the field order of a typical video clip, the frame needs to have been weaved back together already, so avs_is_field_based should actually report 'false' when checked.

* http: Send a Range header even when the offset is 0Justin Ruggles2022-02-11
| | | | | | | Using Range allows for getting the full file size from the Content-Range header in the response, even if the server sends back the response using chunked Transfer-Encoding, which does not allow using Content-Length.
* http: Improve handling of Content-Range with Transfer-Encoding:chunkedJustin Ruggles2022-02-11
| | | | | | | When Transfer-Encoding:chunked is used, the client must ignore a Content-Length header, if present. However, it should not ignore a Content-Range header, which also includes the full size of the entity.
* avformat/mpegts: initialize max_packet_size when sub-demuxerGyan Doshi2022-02-10
| | | | | | | | | | | bca30570d2 added a user option to set max_packet_size replacing a hardcoded value. This had a side-effect of leaving the field set to 0 when packet demuxing is carried out from another demuxer using avpriv functions, which could lead to demux failure. Hardcoded max_packet_size inside avpriv_mpegts_parse_open to 2048000 to avoid this. Value chosen to be 10x that of default value to accommodate large payloads.

* avformat/hls: Implement support for using AVSEEK_FLAG_BACKWARD when seekingGustav Grusell2022-02-09
| | | | | | | | | Before, seeking in hls streams would always seek to the next keyframe after the given timestamp. With this fix, if seeking in videostream and AVSEEK_FLAG_BACKWARD is set, seeking will be to the first keyframe of the segment containing the given timestamp. This fixes #7485.
