we'd memset() the codec context to zero, thereby setting audio input to U8
and video to YUV420P. For most video encoders, that actually works, but for
most audio codecs, it doesn't. This patch changes defaults to those set by
avcodec_context_get_defaults() and have ffmpeg figure out the optimal encoding
format itself if not set explicitely (as it does for the non-ffserver-cases
also).

ffmpeg.c uses lrintf(), which is missing on some systems. Previously
it picked up the replacement via libavutil/internal.h due to
HAVE_AV_CONFIG_H being erroneously defined.
Moving these replacements to a separate header enables ffmpeg.c to
use them without being exposed to internal interfaces.
This use of a non-public header is justified by the header in question
not being part of the internal interface either. It should rather be
considered as part of the build system, which is shared between the
libraries and the applications.
This header cannot be installed since the tested conditions depend on
the compiler.

Its now possible to also select programs per input file and there is
less code duplication.

Should fix different results between PPC and x86 for the idroq-video-encode

Guess the duration before converting video and write guessed duration
into flv header.

The change to ffmpeg.c is wrong as input and output files arent connected 1:1
(i seem to have missed that)
Also it can segfault see ([FFmpeg-devel] rtp streaming x264+audio issues (and some ideas to fix them))

fix the warning:
ffmpeg.c: In function ‘output_packet’:
ffmpeg.c:1317: warning: suggest parentheses around && within ||

This correct the stop point for demuxing with -vcodec copy and -t as well as
packet interleaving. (we already diddrop packets but kept demuxing them
for too long due to opts being wrong)
the change to ffm is due to 2 packets with timestamp 0 being stored
in different order.

This fixes at least ogg encoding with -t where the file was slightly too long.

because CODEC_CAP_SUBFRAMES is primarely misused to hide this warning otherwise
which renders the flag completely useless.

The various avcodec_thread_init() functions are updated to return
immediately after setting avctx->thread_count. This allows -threads 0
to pass through to codecs. It also simplifies the usage for apps
using libavcodec.

This option limits the CPU time used by ffmpeg to the number of seconds
specified. After this time, the OS sends a SIGXCPU signal, which we
handle and attempt to exit cleanly. If the process is stuck, the OS
will deliver a SIGKILL one second later, forcibly terminating the
process.
This functionality is useful in automated setups where a runaway ffmpeg
process would otherwise go undetected.

This is already done by avcodec_thread_init().
