* avfilter/xstack: Add support for fixed size gridVignesh Venkatasubramanian2022-07-04
| | | | | | | | | | | | Add a short hand parameter for making a fixed size grid. The existing xstack layout parameter syntax gets tedious if all one wants is a matrix like grid of the input streams. Add a grid option to the xstack filter that simplifies this use case by simply specifying the number of rows and columns instead of specific x/y co-ordinate for each stream. Also updating the filter documentation to explain the new option. Signed-off-by: Vignesh Venkatasubramanian <vigneshv@google.com>
* doc/ffmpeg: correct description of -shortestGyan Doshi2022-07-04
| | | | | | -shortest stops 'recording' when the shortest output stream ends. The native or even seek-adjusted duration of the source input stream isn't considered.

* avformat/hlsenc: Use HLS version 2 if rounded durations are enabledLucy2022-06-29
| | | | | | | | | | | | | | | | | This allows for wider compatibility with older devices, such as those running iOS 3. The only difference between HLS version 2 and version 3 is that version 3 supports non-integer EXTINF values, and as such, we can default to version 2 if we're using whole-integer EXTINFs anyways, when `-hls_flags round_durations` is set. As this code seems to otherwise consistently use the lowest compatible version, this seems to fit in properly with existing behavior. Testing confirms with that this patch, HLS output can work all the way back to iOS 3. Reviewed-by: Steven Liu <liuqi05@kuaishou.com> Signed-off-by: Lucy <lucy@absolucy.moe>
* libavcodec/qsvenc: Enable fixed QP configure in qsv CQP runtimeYue Heng2022-06-27
| | | | | | | | | | Enable dynamic QP configuration in runtime on qsv encoder. Through AVFrame->metadata, we can set key "qsv_config_qp" to change QP configuration when we encode video in CQP mode.

* 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>

* 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>
