* examples/decode_filter_video: Add loop for draining the filtergraphTobias Rapp2024-03-281-0/+19
| | | | | | | | | Depending on the filters used, the filtergraph may produce trailing data after feeding it the last input frame. Update the example to include the necessary loop for draining the filtergraph. Reviewed-by: Stefano Sabatini <stefasab@gmail.com> Signed-off-by: Tobias Rapp <t.rapp@noa-archive.com>

* 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>

* avutil/film_grain_params: add av_film_grain_params_select()Niklas Haas2024-03-231-0/+3
| | | | | | | | Common utility function that can be used by all codecs to select the right (any valid) film grain parameter set. In particular, this is useful for AFGS1, which has support for multiple parameters. However, it also performs parameter validation for H274.
* avutil/film_grain_params: add metadata to common structNiklas Haas2024-03-231-0/+6
| | | | | | | | | | | | This is needed for AV1 film grain as well, when using AFGS1 streams. Also add extra width/height and subsampling information, which AFGS1 cares about, as part of the same API bump. (And in principle, H274 should also expose this information, since it is needed downstream to correctly adjust the chroma grain frequency to the subsampling ratio) Deprecate the equivalent H274-exclusive fields. To avoid breaking ABI, add the new fields after the union; but with enough of a paper trail to hopefully re-order them on the next bump.

* avutil/frame: Rename av_frame_side_data_get and add wrapper for itAndreas Rheinhardt2024-03-221-1/+4
| | | | | | | | | | | | | | | | | | | av_frame_side_data_get() has a const AVFrameSideData * const *sd parameter; so calling it with an AVFramesSideData **sd like AVCodecContext.decoded_side_data (or with a AVFramesSideData * const *sd) is safe, but the conversion is not performed automatically in C. All users of this function therefore resort to a cast. This commit changes this: av_frame_side_data_get() is renamed to av_frame_side_data_get_c(); furthermore, a static inline wrapper for it name av_frame_side_data_get() is added that accepts an AVFramesSideData * const * and converts this to const AVFramesSideData * const * in a Wcast-qual safe way. This also allows to remove the casts from the current users. Reviewed-by: Jan Ekström <jeebjp@gmail.com> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
