Also query time only once, not for every variant stream, otherwise variant
streams might get a slightly different initial program date time. And we can
set this unconditionally because HLS_PROGRAM_DATE_TIME flag is checked
elsewhere.

Threaded input can increase smoothness of e.g. x11grab significantly. Before
this patch, in order to activate threaded input the user had to specify a
"dummy" additional input, with this change it is no longer required.

Greetings!
unconditional AVFMT_TS_DISCONT also helps to survive when pts rollover in
mpegts occurs.
seems like this patch will break again reading long-lasting hls.

GCC complains:
warning: listing the stack pointer register ‘$29’ in a clobber

Actually stack pointer was restored at the end of the inline assembly
so there is no reason to add it to the clobber list.
Also use $sp insted of $29 to make our intention much more
Add MMI & MSA runtime detection for MIPS.
Basically there are two code pathes. For systems that
natively support CPUCFG instruction or kernel emulated
that instruction, we'll sense this feature from HWCAP and
report the flags according to values grab from CPUCFG. For
systems that have no CPUCFG
This series adds MIPS MSA & MMI runtime detection support
Please review.
Thanks!
v2:
- Add CPUCFG support.
- Add "-mloongson-ext" to MMIFLAGS for Loongson-3 as well. (Loongson2F don't
need this flag)
v3:
- Address reveiew suggestions from Shiyou Yin and Weixi Gu.
v4:
- Disable DSP
To enable runtime detection for MIPS, we need to refine ffbuild
part to support buildding these feature together.
Firstly, we fixed configure, let it probe native ability of toolchain
to decide wether a feature can to be enabled, also clearly marked

Change BitBuf into uint64_t on 64-bit x86. This means we need to flush the
buffer less often, which is a significant speed win. All other platforms,
including all 32-bit ones, are unchanged. Output bitstream is the same.
All API constraints are kept in place, e.g., you still cannot put_bits()
Preparatory patch for making the bit buffer different size on different
platforms; make a typedef and make all the hardcoded sizes into expressions
deriving from this size.
No functional change; generated assembler is near-identical.

This patch adds support for PPM marker for JPEG2000

The codeblock decoder checks whether the mqc decoder
has decoded the right number of bytes. However, this
check does not account for the fact that the mqc encoder's
flush routine adds 2 bytes of data which does not have to be
read by the decoder. The check is modified
From: Gautam Ramakrishnan
The JPEG2000 standard reserves marker values 0xFF30
to 0xFF3F to be used as parameterless markers. This
patch adds support to decode codestream with such
markers. This allows decoding of p0_02.j2k.
