* lavu: deprecate av_opt_set_int_list() and related infrastructureAnton Khirnov2024-09-301-0/+5
| | | | It has no more users and is replaced by array-type options.
* lavfi/buffersink: add array-type options to replace "int-list" onesAnton Khirnov2024-09-301-0/+18
| | | | | | | | "int-list" options are a hack that provides rudimentary support for array-type options by treating them as byte arrays (i.e. AV_OPT_TYPE_BINARY). Since we now have proper array-type options, they should replace "int-list" everywhere (which happens to be just buffersink).

* avcodec: add avcodec_get_supported_config()Niklas Haas2024-09-081-0/+5
| | | | | | | | | | | | | | | | This replaces the myriad of existing lists in AVCodec by a unified API call, allowing us to (ultimately) trim down the sizeof(AVCodec) quite substantially, while also making this more trivially extensible. In addition to the already covered lists, add two new entries for color space and color range, mirroring the newly added negotiable fields in libavfilter. Once the deprecation period passes for the existing public fields, the rough plan is to move the commonly used fields (such as pix_fmt/sample_fmt) into FFCodec, possibly as a union of audio and video configuration types, and then implement the rarely used fields with custom callbacks.

* lavu/opt: add API for setting array-type option valuesAnton Khirnov2024-09-061-0/+3
| | | | | | Previously one could only replace the entire array with a new one deserialized from a string. The new API allows inserting, replacing, and removing arbitrary element ranges.
* lavu/opt: add API for retrieving array-type option valuesAnton Khirnov2024-08-271-0/+3

| | | | | | | | | And av_stream_get_codec_timebase(). They were both added for ffmpeg CLI, which no longer calls either of them. Furthermore the notion of "internal stream timing info" that needs to be transferred with a special magic API function is fundamentally flawed and should be removed.

* avutil/pix{desc,fmt}: add new matrix coefficients from H.273 v3Jan Ekström2024-04-031-0/+4
| | | | | | | | | | | | * SMPTE ST 2128 IPT-C2 defines the coefficients utilized in DoVi Profile 5. Profile 5 can thus now be represented in VUI as {AVCOL_RANGE_JPEG, AVCOL_PRI_BT2020, AVCOL_TRC_SMPTE2084, AVCOL_SPC_IPT_C2, AVCHROMA_LOC_LEFT} (although other chroma sample locations are allowed). AVCOL_TRC_SMPTE2084 should in this case be interpreted as 'PQ with reshaping'. * YCgCo-Re and YCgCo-Ro define the bitexact YCgCo-R, where the number of bits added to a source RGB bit depth is 2 (i.e., even) and 1 (i.e., odd), respectively.

* avformat/demux: add duration_probesize AVOptionNicolas Gaullier2024-04-021-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | Yet another probesize used to get the durations when estimate_timings_from_pts is required. It is aimed at users interested in better durations probing for itself, or because using avformat_find_stream_info indirectly and requiring exact values: for concatdec for example, especially if streamcopying above it. The current code is a performance trade-off that can fail to get video stream durations in a scenario with high bitrates and buffering for files ending cleanly (as opposed to live captures): the physical gap between the last video packet and the last audio packet is very high in such a case. Default behaviour is unchanged: 250k up to 250k << 6 (step by step). Setting this new option has two effects: - override the maximum probesize (currently 250k << 6) - reduce the number of steps to 1 instead of 6, this is to avoid detecting the audio "too early" and failing to reach a video packet. Even if a single audio stream duration is found but not the other audio/video stream durations, there will be a retry, so at the end the full user-overriden probesize will be used as expected by the user.

* avutil/timestamp: introduce av_ts_make_time_string2 for better precisionMarton Balint2024-03-251-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | av_ts_make_time_string() used "%.6g" format, but this format was losing precision even when the timestamp to be printed was not that large. For example for 3 hours (10800) seconds, only 1 decimal digit was printed, which made this format inaccurate when it was used in e.g. the silencedetect filter. Other detection filters printing timestamps had similar issues. Also time base parameter of the function was *AVRational instead of AVRational. Resolve these problems by introducing a new function, av_ts_make_time_string2(). We change the used format to "%.*f", use a precision of 6, except when printing values near 0, in which case we calculate the precision dynamically to aim for a similar precision in normal form as with %.6g. No longer using scientific representation can make parsing the timestamp easier for the users, we can safely do this because the theoretical maximum of INT64_MAX*INT32_MAX still fits into the string buffer in normal form. We somewhat imitate %g by trimming ending zeroes and the potential decimal point characters. In order not to trim "inf" as well, we assume that the decimal point string does not contain the letter "f". Note that depending on printf %f implementation, we might trim "infinity" to "inf". Thanks for Allan Cady for bringing up this issue. Signed-off-by: Marton Balint <cus@passwd.hu>
