* avformat/http,tls: honor http_proxy command line variable for HTTPSMoritz Barsnick2021-03-19
| | | | | | | | | | | | | | | | | | 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>
* lavc/videotoolboxenc: Add support for HEVC with Alpha.Hironori Bono2021-03-19
| | | | | | | | | | | | | | | This change supports the "HEVC Video with Alpha" profile introduced in WWDC 2019 <https://developer.apple.com/videos/play/wwdc2019/506/>. (This change is a partial fix for Ticket #7965.) For example, the following command converts an animation PNG file to an HEVC with Alpha video: ./ffmpeg -i fate-suite/apng/clock.png -c:v hevc_videotoolbox -allow_sw 1 -alpha_quality 0.75 -vtag hvc1 clock.mov (This change uses the "HEVC Video with Alpha" profile only when the '-alpha_quality' value is not 0 for backward compatibility.)

* avutil/adler32: Switch av_adler32_update() to size_t on bumpAndreas Rheinhardt2021-03-19
| | | | | | | | | | 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.

* avformat: Make AVChapter.id an int64_t on next major bumpAndreas Rheinhardt2021-03-19
| | | | | | | | | 64 bits are needed in order to retain the uid values of Matroska chapters; the type is kept signed because the semantics of NUT chapters depend upon whether the id is > 0 or < 0.

* avformat/matroskaenc: Check chapter ids for duplicatesAndreas Rheinhardt2021-03-19
| | | | | | | | | | | | | | | Up until now, there has been no check that each chapter has a unique id; there was only a check for whether a chapter id is zero (this happens often when the chapters originated from a format that lacks the concept of chapter id and simply counts from zero) which is invalid in Matroska. In this case the chapter ids are offset by 1 to make them nonnegative. Yet offsetting won't fix duplicate ids, therefore this is changed to simply create new chapter uids when the input chapter uids don't conform to the requirements of Matroska (in which case it can be presumed that they did not originate from Matroska, so that we don't need to bother to preserve them).

* avformat/tests/fifo_muxer: Fix memleak on error, fix API violationAndreas Rheinhardt2021-03-19
| | | | | | | | | | The test program for the FIFO muxer allocates a buffer without padding and wraps it into a packet via av_packet_from_data(). This is an API violation. Furthermore, said buffer leaks in case av_packet_from_data() fails. Fix both of these issues by using av_new_packet() instead.

* avformat/mxfdec: Don't use wrong type of pointerAndreas Rheinhardt2021-03-19
| | | | | | | | | | | If one of the two results of a ternary conditional is a pointer to void, the type of the whole conditional operator is a pointer to void, even when the other possible result is not a pointer to void. This loophole in the type system has allowed mxf_read_local_tags to have a pointer of type pointer to MXFMetadataSet that actually points to an MXFContext.
