avformat/movenc: add support for fragmented TTML muxing

Attempts to base the fragmentation timing on other streams as most receivers expect media fragments to be more or less aligned.

avcodec/mjpegdec: Avoid mixing return value and error code, avoid branch

15 September 15:52 - FFmpeg - Andreas Rheinhardt

mjpeg_decode_dc() currently has a special return value (0xfffff) for the case of invalid data; this value does not overlap with the ordinary return values, yet the compiler can't prove this (at least on x86 where an asm version of NEG_USR32 is used inside get_xbits()), so the non-error return value has to be checked for being the special value even if mjpeg_decode_dc() is inlined. This commit avoids this by separating error code and ordinary return value.

vf_colorspace: Add an option to clamp trc LUT output

15 September 14:39 - FFmpeg - Drew Dunne

Add a new flag to the vf_colorspace filter which provides the user an option to clamp the linear and delinear transfer characteristics LUT values to the [0, 1] represented range.

support: add check_mem_access function

15 September 08:47 - glibc - Yury Khrustalev

avformat/whip: enable RTCP NACK for whip

15 September 06:40 - FFmpeg - Jack Lau

Refer to RFC 4585 4.2, Add SDP "a=rtcp-fb" so the peer can request rtx through sending NACKs. Add basic parsing for NACK packet.
