* avformat/http,tls: honor http_proxy command line variable for HTTPSMoritz Barsnick2021-03-191-0/+4
| | | | | | | | | | | | | | | | | | Add the "http_proxy" option and its handling to the "tls" protocol, pass the option from the "https" protocol. The "https" protocol already defines the "http_proxy" command line option, like the "http" protocol does. The "http" protocol properly honors that command line option in addition to the environment variable. The "https" protocol doesn't, because the proxy is evaluated in the underlying "tls" protocol, which doesn't have this option, and thus only handles the environment variable, which it has access to. Fixes #7223. Signed-off-by: Moritz Barsnick <barsnick@gmx.net> Signed-off-by: Marton Balint <cus@passwd.hu>

* avutil/adler32: Switch av_adler32_update() to size_t on bumpAndreas Rheinhardt2021-03-191-0/+7
| | | | | | | | | | av_adler32_update() is used by av_hash_update() which will be switched to size_t at the next bump. So it also has to be made to use size_t. This is also necessary for framecrcenc.c, because the size of side data will become a size_t, too.

* lavc: rename AV_CODEC_CAP_AUTO_THREADS->AV_CODEC_CAP_OTHER_THREADSAnton Khirnov2021-03-161-0/+5
| | | | | | | | | | This cap is currently used to mark multithreading-capable codecs that wrap external libraries with their own multithreading code. The name is highly confusing for our API users, since libavcodec ALWAYS handles thread_count=0 (see commit message in previous commit). Therefore rename the cap and update its documentation to make its meaning clear. The old name is kept deprecated until next+1 major bump.

* avformat/gopher: Add support for Gopher over TLSparazyd2021-03-112-0/+7
| | | | | | | | | | | | | | | | This commit adds a "gophers" handler to the gopher protocol. gophers is a community-adopted protocol that acts the same way like normal gopher with the added TLS encapsulation. The gophers protocol is supported by gopher servers like geomydae(8), and clients like curl(1), clic(1), and hurl(1). This commit also adds compilation guards to both gopher and gophers, since now there are two protocols in the file it makes sense to have this addition.

* avformat: Deprecate AVFMT_FLAG_PRIV_OPT, remove av_demuxer_open on bumpAndreas Rheinhardt2021-03-031-0/+4
| | | | | | | | | | | | | | | | | | | | | | | This flag was added in 492026209b9b58eaf6d2ea56423f6b1e1a8a76a5 in conjunction with av_demuxer_open() to allow to pass private options to demuxers. It worked as follows: av_open_input_stream() (the predecessor of avformat_open_input()) would not call the read_header function if this flag is set. Instead the user could set private options of the demuxer via the format's private class after avformat_open_input() and then call av_demuxer_open() which called the format's read_header function. This approach was abandoned in e37f161e66e042d6c2c7470c4d9881df9427fc4a and av_demuxer_open() deprecated; instead the AVDictionary based way of passing private options to the demuxer was choosen. Yet AVFMT_FLAG_PRIV_OPT has never been deprecated and av_demuxer_open() never removed. This commit implements the deprecation of the flag and schedules av_demuxer_open for removal on the next major bump. Given that av_demuxer_open() has been deprecated in 2012 and that this flag is useless without it, the flag will be ignored after the next major version bump.

* lavu/tx: support in-place FFT transformsLynne2021-02-211-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit adds support for in-place FFT transforms. Since our internal transforms were all in-place anyway, this only changes the permutation on the input. Unfortunately, research papers were of no help here. All focused on dry hardware implementations, where permutes are free, or on software implementations where binary bloat is of no concern so storing dozen times the transforms for each permutation and version is not considered bad practice. Still, for a pure C implementation, it's only around 28% slower than the multi-megabyte FFTW3 in unaligned mode. Unlike a closed permutation like with PFA, split-radix FFT bit-reversals contain multiple NOPs, multiple simple swaps, and a few chained swaps, so regular single-loop single-state permute loops were not possible. Instead, we filter out parts of the input indices which are redundant. This allows for a single branch, and with some clever AVX512 asm, could possibly be SIMD'd without refactoring. The inplace_idx array is guaranteed to never be larger than the revtab array, and in practice only requires around log2(len) entries. The power-of-two MDCTs can be done in-place as well. And it's possible to eliminate a copy in the compound MDCTs too, however it'll be slower than doing them out of place, and we'd need to dirty the input array.

* avdevice/avdevice: Deprecate AVDevice Capabilities APIAndreas Rheinhardt2021-02-141-0/+4
| | | | | | | | | | | | | | It has been added in 6db42a2b6b22e6f1928fafcf3faa67ed78201004, yet since then none of the necessary create/free_device_capabilities functions has been implemented, making this API completely useless. Because of this one can already simplify avdevice_capabilities_free/create and can already remove the function pointers at the next major bump; given that the documentation explicitly states that av_device_capabilities is not to be used by a user, it's options can already be removed (save for the sentinel).
