* avdevice/pulse_audio_dec: deprecate frame_size optionMarton Balint2022-06-16
| | | | | | It does not do anything. Frame sizes can be controlled by using fragment_size. Signed-off-by: Marton Balint <cus@passwd.hu>
* avdevice/pulse_audio_dec: reduce default fragment sizeMarton Balint2022-06-16
| | | | | | | | | | | | | Reduces default fragment size from the pulse audio default of 2 sec to 50 ms. This also has an effect on the size of the returned frames, which will be around 50 ms as well, making timestamps more accurate. This should fix the regression in ticket #9776. Pulseaudio timestamps for monitor sources are still pretty inaccurate for me, but I don't see how else should we query latencies from the library. Signed-off-by: Marton Balint <cus@passwd.hu>

* ffprobe: add -o optionStefano Sabatini2022-06-13
| | | | | | | | | | This enables printing to a resource specified with -o OUTPUT. In case the output is not specified, prints to stdout as usual. Address issue: http://trac.ffmpeg.org/ticket/8024 Signed-off-by: Marton Balint <cus@passwd.hu>

* ffmpeg: add option fps_modeGyan Doshi2022-06-11
| | | | | | | fps_mode sets video sync per output stream. Overrides vsync for matching streams. vsync is deprecated.
* avformat/librist: allow setting fifo size and fail on overflowGijs Peskens2022-06-09
| | | | | | | | | | Introduce fifo_size and overrun_nonfatal params to configure fifo buffer behavior. Use newly introduced RIST_DATA_FLAGS_OVERFLOW flag to check for overrun and error out in that case. Signed-off-by: Marton Balint <cus@passwd.hu>
* libavcodec/qsvenc: Add min/max QP control options for I/P/B frameYue Heng2022-06-06
| | | | | | | | | To do more accurate QP control, add min/max QP control on I/P/B frame separately to qsv encoder. qmax and qmin still work but newly-added options have higher priority. Signed-off-by: Yue Heng <yue.heng@intel.com> Signed-off-by: Wenbin Chen <wenbin.chen@intel.com>

* libavutil: Deprecate av_fopen_utf8, provide an avpriv versionMartin Storsjö2022-05-23
| | | | | | | | | | | | | | | | | | | | | | Since every DLL can use an individual CRT on Windows, having an exported function that opens a FILE* won't work if that FILE* is going to be used from a different DLL (or from user application code). Internally within the libraries, the issue can be worked around by duplicating the function in all libraries (this already happened implicitly because the function resided in file_open.c) and renaming the function to ff_fopen_utf8 (so that it doesn't end up exported from the DLLs) and duplicating it in all libraries that use it. This makes the avpriv_fopen_utf8 / ff_fopen_utf8 function work in the exact same way as the existing avpriv_open / ff_open, with the same setup as introduced in e743e7ae6ee7e535c4394bec6fe6650d2b0dbf65. That mechanism doesn't work for external users, thus deprecate the existing function. Signed-off-by: Martin Storsjö <martin@martin.st>

* lavfi: add vf_iccdetect for parsing ICC profilesNiklas Haas2022-04-23
| | | | | | | | | | | | | | | This filter is designed to parse embedded ICC profiles and attempt extracting colorspace tags from them, updating the AVFrame metadata accordingly. This is intentionally made a separate filter, rather than being part of libavcodec itself, so that it's an opt-in behavior for the time being. This also gives the user more flexibility to e.g. first attach an ICC profile and then also set the colorspace tags from it. This makes #9673 possible, though not automatic.

* lavfi: add vf_iccgen for generating ICC profilesNiklas Haas2022-04-23
| | | | | | | | | This filter is designed to specifically cover the task of generating ICC profiles (and attaching them to output frames) on demand. Other tasks, such as ICC profile loading/stripping, or ICC profile application, are better left to separate filters (or included into e.g. vf_setparams). Signed-off-by: Niklas Haas <git@haasn.dev>
