* avfilter: add overlay vaapi filterXinpeng Sun2022-01-17
| | | | | | | | | | | | | | | | | | | | | | | Overlay one video on the top of another. It takes two inputs and has one output. The first input is the "main" video on which the second input is overlaid. This filter requires same memory layout for all the inputs. An example command to use this filter to overlay overlay.mp4 at the top-left corner of the main.mp4: ffmpeg -init_hw_device vaapi=foo:/dev/dri/renderD128 \ -hwaccel vaapi -hwaccel_device foo -hwaccel_output_format vaapi -c:v h264 -i main.mp4 \ -hwaccel vaapi -hwaccel_device foo -hwaccel_output_format vaapi -c:v h264 -i overlay.mp4 \ -filter_complex "[0:v][1:v]overlay_vaapi=0:0:100:100:0.5[t1]" \ -map "[t1]" -an -c:v h264_vaapi -y out_vaapi.mp4 Signed-off-by: U.

* avformat/matroskaenc: Add option to shift data to write cues at frontAndreas Rheinhardt2022-01-13
| | | | | | | | | | | | | This is similar to the faststart option of the mov muxer, yet in contrast to it it works together with reserve_index_space (the equivalent to reserved_moov_size): If the reserved space does not suffice, the data is shifted; if not, the Cues are written at the front without shifting the data. Several tests that cover (not only) this have been added. Implements #7017. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avformat/mov: add option max_stts_deltaGyan Doshi2021-12-31
| | | | | | | | | | | | | | | | Very high stts sample deltas may occasionally be intended but usually they are written in error or used to store a negative value for dts correction when treated as signed 32-bit integers. This option lets the user set an upper limit, beyond which the delta is clamped to 1. Values greater than the limit if negative when cast to int32 are used to adjust onward dts. Unit is the track time scale. Default is UINT_MAX - 48000*10 which allows upto a 10 second dts correction for 48 kHz audio streams while accommodating 99.9% of uint32 range.

* avcodec/libx26[45]: add udu_sei option to import user data unregistered SEIsLimin Wang2021-12-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | Most of user data unregistered SEIs are privated data which defined by user/ encoder. currently, the user data unregistered SEIs found in input are forwarded as side-data to encoders directly, it'll cause the reencoded output including some useless UDU SEIs. I prefer to add one option to enable/disable it and default is off after I saw the patch by Andreas Rheinhardt: https://patchwork.ffmpeg.org/project/ffmpeg/patch/AM7PR03MB66607C2DB65E1AD49D975CF18F7B9@AM7PR03MB6660.eurprd03.prod.outlook.com/ How to test by cli: ffmpeg -y -f lavfi -i testsrc -c:v libx264 -frames:v 1 a.ts ffmpeg -y -i a.ts -c:v libx264 -udu_sei 1 b.ts ffmpeg -y -i a.ts -c:v libx264 -udu_sei 0 c.ts # check the user data unregistered SEIs, you'll see two UDU SEIs for b.ts. # and mediainfo will show with wrong encoding setting info ffmpeg -i b.ts -vf showinfo -f null - ffmpeg -i c.ts -vf showinfo -f null - This fixes tickets #9500 and #9557.

* avdevice/dshow: implement option to use device video timestampsDiederick Niehorster2021-12-24
| | | | | | | | | | | | | | | | | | | | | The dshow avdevice ignores timestamps for video frames provided by the DirectShow device, instead using wallclock time, apparently because the implementer of this code had a device that provided unreliable timestamps. Me (and others) would like to use the device's timestamps. The new use_video_device_timestamps option for dshow device enables them to do so. Since the majority of video devices out there probably provide fine timestamps, this patch sets the default to using the device timestamps, which means best fidelity timestamps are used by default. Using the new option, the user can switch this off and revert to the old behavior, so a fall back remains available in case the device provides broken timestamps. add use_video_device_timestamps to docs.

* avformat: introduce AVFormatContext io_close2 which returns an intMarton Balint2021-12-12
| | | | | | | | | | | | | | | | | Otherwise there is no way to detect an error returned by avio_close() because ff_format_io_close cannot get the return value. Checking the return value of the close function is important in order to check if all data was successfully written and the underlying close() operation was successful. It can also be useful even for read mode because it can return any pending AVIOContext error, so the user don't have to manually check AVIOContext->error. In order to still support if the user overrides io_close, the generic code only uses io_close2 if io_close is either NULL or the default io_close callback.

* ffmpeg: rewrite setting the stream dispositionAnton Khirnov2021-11-16
| | | | | | | | | | | | | | | | | | | | | Currently, the code doing this is spread over several places and may behave in unexpected ways. E.g. automatic 'default' marking is only done for streams fed by complex filtergraphs. It is also applied in the order in which the output streams are initialized, which is effectively random. Move processing the dispositions at the end of open_output_file(), when we already have all the necessary information. Apply the automatic default marking only if no explicit -disposition options were supplied by the user, and apply it to the first stream of each type (excluding attached pics) when there is more than one stream of that type and no default markings were copied from the input streams. Explicitly document the new behavior. Changes the results of some tests, where the output file gets a default disposition, while it previously did not.
