Forced key frames generation functionality was assuming the first PTS
value as zero, but, when 'copyts' is enabled, the first PTS can be any
big number. This was eventually forcing all the frames as key frames.
To resolve this issue, update has been made to use first input pts as
reference pts.

With certain types of input and the filter chain getting re-initialized
or re-configured, multiple nullptr AVSubtitles can get pushed into
sub2video_update() in a row from sub2video_heartbeat.
This causes end_pts, and on the next round pts, to become INT64_MAX,
latter of which signals EOF in framesync, leading to complete loss of
subtitles from that point on.
Thus, check that the sub2video.end_pts is smaller than INT64_MAX
in a similar fashion to sub2video_flush before sending out the
nullptr AVSubtitle. This keeps premature EOFs from happening in
framesync and the subtitle overlay is kept past the filter chain
re-initializations/configurations.
The generic code should be able to finish the streams just fine initializing
and flushing the filters and codecs properly.
Fixes the following command:
ffmpeg -f lavfi -i "testsrc=d=0.1[out0];aevalsrc=0:d=0[out1]" -af apad -shortest -f framecrc -

It's been a noop for years, and it's been argued that in-band headers
should not be forcedly removed without the user's explicit request.
Also, as the FIXME line stated, this is a job for a bitstream filter
like extract_extradata, remove_extradata, dump_extradata, and
filter_units.

When a decoded stream is being looped, after each post-EOF rewind,
decoders are flushed in seek_to_start(). This only drains 1 frame, and
thus the output has a few frames missing at the tail of each iteration
except the last.
With this patch, process_input is looped till process_input_packet
reaches EOF.
Fixes#7081

On systems which deliver SIGPIPE (Unices), a broken pipe will currently
result in the immediate termination of the ffmpeg process (the default
disposition as required by POSIX). This is undesirable, because while
the broken pipe is likely fatal to useful cleanup of whatever component
is writing to it, there might be other components which can do useful
cleanup - for example, a muxer on another stream may still need to write
indexes to complete a file. Therefore, set the signal disposition for
SIGPIPE to ignore the signal - the call which caused the signal will
fail with EPIPE and the error will be propagated upwards like any other
I/O failure on a single stream.
add return value check to supress the build warning message like
"warning: ignoring return value" when use attribute -Wunused-result.

With there being two hwaccels that use the CUDA pix_fmt now, just
relying on the pix_fmt to identify the selected hwaccel is not enough
anymore.
So this checks if the user explicitly selected a hwaccel, and only
accepts that one.

Since af1761f7b5 ffmpeg waits for a frame in each
stream before writing the output header. If we are using threaded decoding for
attached pictures, we have to read till EOF to be able to finally flush the
decoder and output the decoded frame. This essentially makes ffmpeg buffer all
non-attached picture packets, which will cause a "Too many packets buffered for
output stream" eventually.
By forcing single threaded decoding, we get a frame from a single packet as
well and we can avoid the error.
