* avformat/mpegtsenc: get rid of packet counting for sdt/pat/pmtMarton Balint2019-08-23
| | | | | | | | | | | | | The packet counting based approach caused excessive sdt/pat/pmt for VBR, so let's use a timestamp based approach instead similar to how we emit PCRs. SDT/PAT/PMT period should be consistent for both VBR and CBR from now on. Also change the type of sdt_period and pat_period to AV_OPT_TYPE_DURATION so no floating point math is necessary. Fixes ticket #3714. Signed-off-by: Marton Balint <cus@passwd.hu>

* avcodec/lcldec: Check mthread_inlen instead of clipingMichael Niedermayer2019-08-23
| | | | | | | | | | | | | | | | Clipping was added in 2009 to avoid crashes. The clipped case would produce a 2nd slice with 0 input thus also producing 0 output. Subsequent checks will cause decoder failure unless both slices have the same output length. thus the only way this would not already fail is if the output from both slices was 0 bytes.

* Add assembly support for -fsanitize=hwaddress tagged globals.Peter Collingbourne2019-08-22
| | | | | | | | | | | | | | | | | As of LLVM r368102, Clang will set a pointer tag in bits 56-63 of the address of a global when compiling with -fsanitize=hwaddress. This requires an adjustment to assembly code that takes the address of such globals: the code cannot use the regular R_AARCH64_ADR_PREL_PG_HI21 relocation to refer to the global, since the tag would take the address out of range. Instead, the code must use the non-checking (_NC) variant of the relocation (the link-time check is substituted by a runtime check). This change makes the necessary adjustment in the movrel macro, where it is needed when compiling with -fsanitize=hwaddress.
