* avformat/mxfenc: Make init function out of write_headerAndreas Rheinhardt2021-11-18
| | | | | | | | | The MXF muxers only write the header after they have received a packet; the actual write_header function does not write anything. So make an init function out of it. Reviewed-by: Tomas Härdin <tjoppen@acc.umu.se> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avformat/hlsenc: Only write something if there is something to writeAndreas Rheinhardt2021-11-18
| | | | | | | | | | This is especially important in case avio_write() would be switched to an unsigned type like size_t, then a potential error from avio_read() (with negative return value) would no longer be handled gracefully by avio_write().

* avformat/hlsenc: Remove nonsense memsetAndreas Rheinhardt2021-11-18
| | | | | | | | | | | The memset here is both unnecessary (avio_read() ignores the previous content of the destination buffer) as well as nonsense (for a char buf[BUFSIZE] sizeof(buf) and sizeof(BUFSIZE) are not the same; the latter is sizeof(int)).

* avformat/http: Add short_seek_size optionDerek Buitenhuis2021-11-17
| | | | | | | | | | | | | | | In 45bfe8b838275235412777dd430206d9a24eb3ee, short_seek_threshold was removed from the public AVIO struct. Although this option was private and not intended to be used by public API users, it was nonetheless, because it provided functionality that could otherwise not be gained via public API. This was especially important for networked I/O like HTTP, where the internal size for lavf could be way to small depending on the specifics of a user's usecase, such as reading interlavd media files from cloud storage. Add an AVOption to make this functionality accessible to the HTTP client. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>

* aarch64: Add Armv8.5-A BTI supportJonathan Wright2021-11-16
| | | | | | | | | | | | | | | | | Add Branch Target Identifiers (BTIs) to all functions defined in AArch64 assembly files. Most of the BTI landing pads are added automatically by the 'function' macro. BTI support is turned on or off at compile time based on the presence of the __ARM_FEATURE_BTI_DEFAULT feature macro. A binary compiled with BTI support can be executed on an Armv8-A processor without BTI support because the instructions are defined in NOP space.

| | | | | | | | | | | | | | | | | | Change AArch64 assembly code to use: ret x<n> instead of: br x<n> "ret x<n>" is already used in a lot of places so this patch makes it consistent across the code base. This does not change behavior or performance. In addition, this change reduces the number of landing pads needed in a subsequent patch to support the Armv8.5-A Branch Target Identification (BTI) security feature.

* ffmpeg: rewrite setting the stream dispositionAnton Khirnov2021-11-16
| | | | | | | | | | | | | | | | | | | | | Currently, the code doing this is spread over several places and may behave in unexpected ways. E.g. automatic 'default' marking is only done for streams fed by complex filtergraphs. It is also applied in the order in which the output streams are initialized, which is effectively random. Move processing the dispositions at the end of open_output_file(), when we already have all the necessary information. Apply the automatic default marking only if no explicit -disposition options were supplied by the user, and apply it to the first stream of each type (excluding attached pics) when there is more than one stream of that type and no default markings were copied from the input streams. Explicitly document the new behavior. Changes the results of some tests, where the output file gets a default disposition, while it previously did not.

* avfilter/af_apad: do not add infinite silence for zero pad_dur or whole_durMarton Balint2021-11-14
| | | | | | | | | | | | | Unfortunately pad_len and pad_dur behaviour was different if 0 was specified, pad_dur handled 0 duration as infinity, for pad_len, infinity was -1. Let's make the behaviour consistent by handling 0 duration for pad_dur and whole_dur as indeed 0 duration. This somewhat changes the behaviour of the filter if 0 was explicitly specified, but deprecating the old option and adding a new for the corrected behaviour seemed a bit overkill. So let's document the change instead. Signed-off-by: Marton Balint <cus@passwd.hu>
