* avcodec/packet_internal: Add proper PacketList structAndreas Rheinhardt2022-01-04
| | | | | | | | | | | | | | | Up until now, we had a PacketList structure which is actually a PacketListEntry; a proper PacketList did not exist and all the related functions just passed pointers to pointers to the head and tail elements around. All these pointers were actually consecutive elements of their containing structs, i.e. the users already treated them as if they were a struct. So add a proper PacketList struct and rename the current PacketList to PacketListEntry; also make the functions use this structure instead of the pair of pointers.

* avcodec/raw: Reduce number of avpriv symbolsAndreas Rheinhardt2022-01-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | libavcodec currently exports four avpriv symbols that deal with PixelFormatTags: avpriv_get_raw_pix_fmt_tags, avpriv_find_pix_fmt, avpriv_pix_fmt_bps_avi and avpriv_pix_fmt_bps_mov. The latter two are lists of PixelFormatTags, the former returns such a list and the second searches a list for a pixel format that matches a given fourcc; only one of the aforementioned three lists is ever searched. Yet for avpriv_pix_fmt_bps_avi, avpriv_pix_fmt_bps_mov and avpriv_find_pix_fmt the overhead of exporting these functions actually exceeds the size of said objects (at least for ELF; the following numbers are for x64 Ubuntu 20.10): The code size of avpriv_find_pix_fmt is small (GCC 10.2 37B, Clang 11 41B), yet exporting it adds a 20B string for the name alone to the exporting as well as to each importing library; there is more: Four bytes in the exporting libraries .gnu.hash; two bytes each for the exporting as well as each importing libraries .gnu.version; 24B in the exporting as well as each importing libraries .dynsym; 16B+24B for an entry in .plt as well as the accompanying relocation entry in .rela.plt for each importing library. The overhead for the lists is similar: The strings are 23B and the .plt+.rela.plt pair is replaced by 8B+24B for an entry in .got and a relocation entry in .rela.dyn. These lists have a size of 80 resp. 72 bytes. Yet for ff_raw_pix_fmt_tags, exporting it is advantageous compared to duplicating it into libavformat and potentially libavdevice. Therefore this commit replaces all library uses of the four symbols with a single function that is exported for shared builds. It has an enum parameter to choose the desired list besides the parameter for the fourcc. New lists can be supported with new enum values. Unfortunately, avpriv_get_raw_pix_fmt_tags could not be removed, as the fourcc2pixfmt tool uses the table of raw pix fmts. No other user of this function remains.

* avdevice/dshow: ensure pin's default format is setDiederick Niehorster2022-01-04
| | | | | | | | | | | | Fixes regression in a1c4929f: there apparently are devices out there that expose a pin default format that has parameters outside the capabilities of any of the formats exposed on the pin (sic?). The VirtualCam plugin (v 2.0.5) of OBS-Studio (v 27.1.3) is such a device. Now when a default format was found, but not selected when iterating all formats, fall back to directly setting the default format.

* avdevice/dshow: select format with extended color infoDiederick Niehorster2021-12-24
| | | | | | | | | | | | | | | | | | | | | | Some DirectShow devices (Logitech C920 webcam) expose each DirectShow format they support twice, once without and once with extended color information. During format selection, both match, this patch ensures that the format with extended color information is selected if it is available, else it falls back to a matching format without such information. This also necessitated a new code path taken for default formats of a device (when user didn't request any specific video size, etc), because the default format may be one without extended color information when a twin with extended color information is also available. Getting the extended color information when available is important as it allows setting the color space, range, primaries, transfer characteristics and chroma location of the stream provided by dshow, enabling users to get more correct color automatically out of their device.

| | | | | | | | | | | | the list_devices option of dshow didn't indicate whether a specific device provides audio or video output. This patch iterates through all media formats of all pins exposed by the device to see what types it provides for capture, and prints this to the console for each device. Importantly, this now allows to find devices that provide both audio and video, and devices that provide neither.

* avdevice/dshow: set no-seek flagsDiederick Niehorster2021-12-24
| | | | | | | | | | | | | | | | avdevice/dshow is a realtime device and as such does not support seeking. Therefore, its demuxer format should define the AVFMT_NOBINSEARCH, AVFMT_NOGENSEARCH and AVFMT_NO_BYTE_SEEK flags. With these flags set, attempting to seek (with, e.g., avformat_seek_file()) correctly yields -1 (operation not permitted) instead of -22 (invalid argument). This actually seems to apply to many other devices, at least the gdigrab, v4l2, vfwcap, x11grab, fbdev, kmsgrab and android_camera devices, from reading the source.

* 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.
