I have no idea why the first hunk uses ost->enc_ctx, because as far as
I understand, that is never used in case of -c:v copy, but this code
block is only entered if encoding_needed=0, which means stream_copy=1.
My point being: review from someone that knows this really well would
be appreciated.

avconv: pass the hw context from filters to the encoder
Merged-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>
Codec options of streams detected during avformat_find_stream_info are not set
therefore without this patch we initialize the encoders with decoder info
based on decoders without options.
This cause problems for probed DVB teletext streams where
avctx->subtitle_header depend on the txt_format setting.

avio_closep is not guaranteed to succeed, and its return value can
contain information regarding failure of preceding writes and silent
loss of data (man 2 close, man fclose). Users should know when the
progress was not successfully logged, and so a diagnostic is printed
here.

This adds a computation of the progress speed versus realtime ("Nx")
to the status line and to the report log. It uses the progress time
as already calculated for total output time as a base.

-hex and -dump command line options do nothing unless -loglevel debug is set.
-dump by itself is useful for monitoring live streams (to get the current PTS for example) however when it is used with -loglevel debug for an RTMP stream, librtmp also dumps the packet data which makes the output too noisy.
do_pkt_dump is only set in check_keyboard_interaction or by the -dump command line option so this change should have no effect on any other parts of the code..

Using -ss as an input option shifts timestamps down by the seek, so it
doesn't have to be added to the recording time when checking whether to
stop.

FFDIFFSIGN was created explicitly for this purpose, since the common
return a - b idiom is unsafe regarding overflow on signed integers. It
optimizes to branchless code on common compilers.
FFDIFFSIGN also has the subjective benefit of being easier to read due
to lack of ternary operators.
Tested with FATE.
Things not covered by this are unsigned integers, for which overflows
are well defined, and also places where overflow is clearly impossible,
e.g an instance where the a - b was being done on 24 bit values.

This is more concise and conveys the intent better.
Furthermore, it is likely more precise as well due to lack of floating
point division.

avconv: add support for Intel QSV-accelerated transcoding
Merged-by: Hendrik Leppkes <h.leppkes@gmail.com>
On lines 1633,1634 FFABS(pts) is performed. However, if av_stream_get_end_pts
returns AV_NOPTS_VALUE always, pts remains stuck at INT64_MIN, leading
to undefined behavior on FFABS.
One could conceive of a solution using FFNABS. However, such a solution
has to deal with the implementation defined rounding of integer division
with at least one negative operand in ANSI C89. C99 forces truncation to
zero, but I am not sure that all of our platforms compile with full C99
support, and in particular whether we can safely assume a fixed
rounding behavior across all platforms.
This solution is simple, and I doubt changing INT64_MIN to INT64_MIN + 1
has any practical loss - if it is stuck at its initial value, the stream
is messed up anyway.

If threading is used, the first (thread_count - 1) packets are read
before any frame/error is returned. Counting this as successful decoding
is wrong, because it also happens when no single frame could be decoded.
