* avdevice/lavfi: output wrapped AVFramesTimo Rothenpieler2022-07-18
| | | | | | | | | | | | | This avoids an extra copy of potentially quite big video frames. Instead of copying the entire frames data into a rawvideo packet it packs the frame into a wrapped avframe packet and passes it through as-is. Unfortunately, wrapped avframes are set up to be video frames, so the audio frames continue to be copied. Additionally, this enabled passing through video frames that previously were impossible to process, like hardware frames or other special formats that couldn't be packed into a rawvideo packet.
* avdevice/avdevice: fix return value of avdevice_list_devices()Marton Balint2022-07-17
| | | | | | | | | | | | | | According to API docs avdevice_list_devices(), avdevice_list_input_sources() and avdevice_list_input_sinks() should return the number of autodetected devices on success. This is redundant with AVDeviceInfoList->nb_devices so it was not noticed earlier that none of the underlying device list functions work like that. Let's fix it in generic code to make it in line with the API docs. Fixes ticket #9820. Signed-off-by: Marton Balint <cus@passwd.hu>

* avdevice/oss_dec: account for sample size when computing timestampMatt Jacobson2022-06-19
| | | | | | | | | Don't assume each sample is one byte in size. Doing so results in wrong and occasionally non-monotonically-increasing timestamps. Fix nearby cosmetic typo. Signed-off-by: Marton Balint <cus@passwd.hu>
* 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>

* libavcodec, libavdevice: Remove unnecessary includes of version.hMartin Storsjö2022-02-24
| | | | | | | | | | | | | | | xvmc.h used FF_API_* macros before, but they were removed in 1c63aed232febf4404659bf006237ee4f7f17c9c, leaving the include unused. The ones in android_camera.c and mediacodec_wrapper.c have been added due to a misunderstanding, fixed in c0bce367e4932f0fb09195e6978ac1a5a60480a4 and 13b77af2f0b56d6c87bb147947337981c21f4245.

| | | | | | | | | | | | iec61883_parse_queue_hdv() is only called when the mpegts-demuxer is available and can be optimized away when not. Yet this optimization is not a given and it fails with e.g. GCC 11 when using -O0 in which case one will get a compilation error because the call to the unavailable avpriv_mpegts_parse_packet() is not optimized away. Therefore #if the offending code away in this case. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* 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.

* configure, avcodec/Makefile: Add new mpeg4audio CONFIG_EXTRA groupAndreas Rheinhardt2022-01-04
| | | | | | | | | | | | | | | This group is mainly for the users of *_mpeg4audio_get_config2(); it is not for those who only use avpriv_mpeg4audio_sample_rates. This is in preparation for splitting the latter into a file of its own; if there were no CONFIG_EXTRA group for *_mpeg4audio_get_config2() users, one would have to add a dependency to the new file for all these users on top of the existing dependency on mpeg4audio.o. Adding a new CONFIG_EXTRA group only takes effect after a reconfigure; so in order to force a reconfigure some unnecessary headers from libavdevice/alldevices.c have been removed.

* 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.
