* libavformat/hlsplaylist: add subtitle_varname for naming subtitle streamsJonathan Baecker2024-10-131-1/+1
| | | | | | | | | If 'sname:*' is set in the var_stream_map variable, use it as the NAME attribute for subtitles. This improves the naming of subtitle streams in HTML players, providing clearer and more descriptive labels for users. Reviewed-by: Steven Liu <lq@chinaffmpeg.org>
* hlsenc: Calculate the average and actual maximum bitrate of segmentsMartin Storsjö2024-07-041-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, the bitrate advertised in the master playlist would only be based on the nominal values in either AVCodecParameters bit_rate, or via AVCPBProperties max_bitrate. On top of this, a fudge factor of 10% is added, to account for container overhead. Neither of these bitrates may be known, and if the encoder is running in VBR mode, there is no such value to be known. And the container overhead may be more or less than the given constant factor of 10%. Instead, calculate the maximum bitrate per segment based on what actually gets output from the muxer, and average bitrate across all segments. When muxing of the file finishes, update the master playlist with these values, exposing both the maximum (which previously was a guesstimate based on the nominal values) via EXT-X-STREAM-INF BANDWIDTH, and the average via EXT-X-STREAM-INF AVERAGE-BANDWIDTH. This makes it possible to use the hlsenc muxer with VBR encodes, for VOD style muxing. Signed-off-by: Martin Storsjö <martin@martin.st>

* Remove unnecessary libavutil/(avutil|common|internal).h inclusionsAndreas Rheinhardt2022-02-241-1/+0
| | | | | | | | | | Some of these were made possible by moving several common macros to libavutil/macros.h. While just at it, also improve the other headers a bit. Reviewed-by: Martin Storsjö <martin@martin.st> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
