aspect ratio in JPEG JFIF is SAR not DAR !
removed nonsense SAR guessing code
various related cleanups
bugs?

* fixing YUV4MPEG format.
* fixing a bug in DV codec where coded_frame was not set.

* backing out the 0-sized packets patch. We have to devise a more
sensible approach.

quality which was 1..31 float is now a 1..FF_LAMBDA_MAX int, and FF_QP2LAMBDA * qp can be used to convert to the new range

changing pix_fmt at the same time.
* aspect ratio should be more reliable for DV now.
Originally committed as revision 2338 to svn://svn.ffmpeg.org/ffmpeg/trunk
* removes use of read_key and getchar when input is received on stdin
(this was corrupting the packet reading)
* terminates av_encode when a termination signal is received (use of
ctrl-c issued a term_exit and subsequent uses of q failed)
* specific correction to yuv4mpeg pipe reading - the defined header was
too short to allow for extended yuv4mpeg flags [as used by smil2yuv and
y4mscaler and accepted by mjpeg tools]
Originally committed as revision 2183 to svn://svn.ffmpeg.org/ffmpeg/trunk
* -r now does the right thing.
* frame rate and frame sizes now share same abbv. table and you
can do -r ntsc as well as -s ntsc

PMCs, and with Apple's CHUD it's fairly easy too. No reason to keep useless
code around
2) make the PPC perf stuff a configure option
3) make put_pixels16_altivec a bit faster by unrolling the loop by 4

Originally committed as revision 2022 to svn://svn.ffmpeg.org/ffmpeg/trunk
+ avcodec_get_pix_fmt
converts textual representation of pixel format into
the actual id. Complements avcodec_get_pix_fmt_name.
+ avpicture_layout
serializes given picture into a flat array.
Complements avpicture_fill.
* adding a new option -pix_fmt to the ffmpeg, in order to control
pixel format for the codecs that do support it, like rawvideo,
for example.
* reducing complexity of the rawvideo codec by splitting it in two
and making it more reliable via hooking up to the avpicture_layout.
Plus adding new FourCC as described here: http://www.fourcc.org
* A tiny fix for avienc.c that makes avih and video strf consistent
regarding codec FourCC.
Originally committed as revision 1842 to svn://svn.ffmpeg.org/ffmpeg/trunk
* let ffmpeg preserve 'aspect_ratio' for recoding.
Do we want to make it tweakable from the command line ?
