* avdevice/alldevices: Mark iterators as av_coldAndreas Rheinhardt2024-03-17

* avdevice/alldevices: Mark devices as hiddenAndreas Rheinhardt2024-03-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Both GCC and Clang create code that inlines the loops in next_input() and next_output() at high optimization levels (presumably when there are not too many devices) and this code leads to the creation of .got entries: e7: 48 3b 3d 00 00 00 00 cmp 0x0(%rip),%rdi # ee <av_input_video_device_next+0xe> ea: R_X86_64_REX_GOTPCRELX ff_alsa_demuxer-0x4 ee: 74 43 je 133 <av_input_video_device_next+0x53> f0: 48 3b 3d 00 00 00 00 cmp 0x0(%rip),%rdi # f7 <av_input_video_device_next+0x17> f3: R_X86_64_REX_GOTPCRELX ff_fbdev_demuxer-0x4 f7: 74 41 je 13a <av_input_video_device_next+0x5a> These relocations can't be fixed up lateron when it is known that the symbols exist in the same DSO. This commit therefore marks these symbols as hidden, leading to code like this: f7: 48 8d 05 00 00 00 00 lea 0x0(%rip),%rax # fe <av_input_video_device_next+0xe> fa: R_X86_64_PC32 ff_alsa_demuxer-0x4 fe: 48 39 c7 cmp %rax,%rdi 101: 74 55 je 158 <av_input_video_device_next+0x68> 103: 48 8d 05 00 00 00 00 lea 0x0(%rip),%rax # 10a <av_input_video_device_next+0x1a> 106: R_X86_64_PC32 ff_fbdev_demuxer-0x4 10a: 48 39 c7 cmp %rax,%rdi 10d: 74 50 je 15f <av_input_video_device_next+0x6f> (Note: It is actually strange that the compiler creates code that tries to read the addresses from the .got given that the addresses can be read directly from indev_list/outdev_list.)

* avformat/avformat: Add FFInputFormat, hide internals of AVInputFormatAndreas Rheinhardt2024-03-07
| | | | | | | | | | | | | | | | | | | | | This commit does for AVInputFormat what commit 59c9dc82f450638a3068deeb1db5c56f6d155752 did for AVOutputFormat: It adds a new type FFInputFormat, moves all the internals of AVInputFormat to it and adds a now reduced AVInputFormat as first member. This does not affect/improve extensibility of both public or private fields for demuxers (it is still a mess due to lavd). This is possible since 50f34172e0cca2cabc5836308ec66dbf93f5f2a3 (which removed the last usage of an internal field of AVInputFormat in fftools). (Hint: tools/probetest.c accesses the internals of FFInputFormat as well, but given that it is a testing tool this is not considered a problem.)

* 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.

* | Add Win32 GDI-based screen grabbingCalvin Walton2014-04-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Based on original code by Christophe Gisquet in 2010, updated to work with current ffmpeg APIs. Supports grabbing a single window or an area of the screen, including support for multiple monitors (Windows does funky stuff with negative coordinates here). I've moved most of the configuration to AVOptions; the input file name is now only the string "desktop", or "title=<windowname>" to select a single window. The AVOptions are the same as x11grab where possible. Code has been added to support a "show_region" mode, like x11grab, which will draw a rectangle on the screen around the area being captured. Instead of duplicating code for paletted image handling, I make use of the GDI API's ability to output DIB (BMP) images, which can be run through ffmpeg's existing BMP decoder.
