256ef19844 h264: arm: use intra pred8x8 functions only for chroma_format_idc <= 1 2015-07-18 00:28:49 +02:00

a344e5d094 x86: bswapdsp: Don't treat 32-bit integers as 64-bit 
The upper halves are not guaranteed to be zero in x86-64.

Also use `test` instead of `and` when the result isn't used for anything other
than as a branch condition, this allows some register moves to be eliminated.

a062a55d37 hevc_parser: fix standalone build with the hevc decoder disabled

b9f76d19d8 hevc_ps: make sure failing to decode an SPS always returns an error 
Some of the goto err clauses do not set the error code. It seems better
to fall back on INVALIDDATA instead of adding it everywhere explicitly.

d82e1adc20 hevc: move splitting the packet into NALUs into a separate function

ae05b48655 hevc: eliminate the second call to hls_nal_unit() 
Also, make hls_nal_unit() work only on the provided NAL unit, without
requiring a whole decoding context.

86eee85dad bytestream2: set the reader to the end when reading more than available 
This prevents possible infinite loops with the calling code along the
lines of while (bytestream2_get_bytes_left()) { ... }, where the reader
does not advance.

1410eeb6ea imc: Use correct position for flcoeffs2 calculation 
flcoeffs2[pos] should be the log2 of flcoeffs1[pos].
flcoeffs1[0] can be 0 here, thus flcoeffs2[pos] gets set to -inf,
causing problems further down.

This seems to have been copied from imc_decode_level_coefficients in
commit 4eb4bb3 without updating the position.

02b7c63087 h261: Signal freeze picture release for intra frames 
Freeze picture release should be set to 1 when we're responding to a
fast update request. For simplicity we set it for all intra frames,
including those that starts a GOP.

Fixes issue where Tandberg MXP1700 does not recover from packet loss
state since it's waiting for the freeze picture relase indication.

dc1de0b958 h261: Set 'still image mode off' in picture header 
Ref H.261 recommendation section 4.2.1.3, setting the still image flag
to 1 disables still image mode. Some decoders require this in order to
decode the bitstream as normal video.

Fixes H.261 calls to Cisco E20.

Also, reserved (aka spare) bits should be set to 1 unless specified
otherwise.
