Roman Shaposhnik 06ab9cffb2 * fixing -target *dv issues with not setting pix_fmt and adding dv50 target 
Originally committed as revision 5244 to svn://svn.ffmpeg.org/ffmpeg/trunk
 2006-03-30 02:36:02 +00:00
Roman Shaposhnik 56419683b2 I still don't think this should be here. Note: without this code DV encoder 
will accept incorrect pix_fmt's and such, but decoder will work much better
with containers not setting the same attributes. It seems like there will
be a generic mechanism for checking such constraints, but if not I can always
resurrect this check for *encoder* only.

Roman Shaposhnik aa06658248 Moving dv_anchor back to the global scope. This creates a tiny memory 
leak for cases like dlopening libavcodec.so and such, but I still

Roman Shaposhnik f02be79d61 * Introducing IIDC1394 grabbing interface. 
Use it with -grab dc1394

   * Introducing yet another packed pix_fmt in order to support some of
     the IIDC1394 modes: uyvy411 (Cb Y0 Y1 Cr Y2 Y3).

 2004-10-22 02:04:30 +00:00
Roman Shaposhnik 2639c651db * Introducing new UI for grabbing. 
There's an option -grab <format> that basically acts as -i
      but for grabbing. So now it's possible to grab from multiple
      sources at once and fully control -r -s and -pix_fmt for
      each individual grab.

    * removing -dv1394
      Please use -grab dv1394 instead.

 2004-10-13 00:03:00 +00:00
Roman Shaposhnik 5088363247 * experimental dynamic audio stream allocation for DV demuxer. This 
should make Nathan Kurz and if I don't hear too much complaints
     about it -- that's the way it will be from now on.

   * updating regressions

 2004-09-27 22:53:27 +00:00
Roman Shaposhnik 96319c3922 * let DV muxer generate audioless DV streams. This might not be 100% 
complaint with the SMPTE & IEC specs, but it seems harmless enough.
     The way we "specify" that there's no audio is by simply leaving
     audio DIFs filled with 0xff (I bet there's a way to mark this
     properly in the system info section!).

 2004-08-23 19:48:41 +00:00
Roman Shaposhnik 0c9fc6e187 * replacing calls to not-always-available gmtime_r with our own code. 
The new helper function actually differs in semantics from gmtime_r,
     so if that seems to be a problem I can actually move it to dv.c
     completely, since only DV muxer uses the code anyway.

Roman Shaposhnik 8f9298f801 * simplifying OpenDML AVI handling. 
* adding code to skip over JUNK. It turns out that video editing
     software uses junk to resize ix## chunks without actually
     scrubbing the data. That trips up our packet extraction
     code since it recognizes ix## entries as "packets". Basically
     we have to skip over JUNK chunks for exactly the same reason
     we have to skip over ix## entries.

Roman Shaposhnik cac0a56c55 * .mov files with uncompressed audio can't be correctly processed 
because of the sample_size == 1 and MINOLTA hack relying on
      the information. So in a way, it's a hack of a hack.

      btw, if somebody knows why in the world even Apple's software
      thinks that for PCM 16bit sample_size == 1 please let me know.
      It clearly isn't documented that way.

Roman Shaposhnik 380fd6b1b4 * DV decoder simplifications. Now it looks to be 6% faster. At least 
on my desktop.
     * Misc. DV cleanups and fixes.

Roman Shaposhnik e7a18d5deb * moving some of the commonly used bit reading/writing functions 
from common.c -> common.h so that they can be inlined.
         + performace gain ~1% (measured with DV decoding)
	 + code bloat 0.05%
      Looks like a win-win solution.

Roman Shaposhnik 826ca10408 * gotta setup coded_frame for encoding. avcodec.h says that for decoding 
lavc is supposed to set it up as well and I don't think I see any
      reason not to.

Roman Shaposhnik e15c330246 * 3x encoding speedup. Finally we seem to be on par with libdv 
in terms of time and we're doing slightly better w.r.t. to
     quality. I don't think there's much room for improvement
     left, but I'd like to try and vectorize a couple of things.
     Btw, any ideas on what may impact performance will be greatly
     appreciated.

Roman Shaposhnik ddaae6a9d1 * DV demuxer is now capable of decoding auxilary audio stream. So, 
everybody who still uses second streo track for dubbing can
     now export it.

   * void* -> DVDemuxContext* change (per Fabrice's suggestion).

   * -dv1394 capture now works in all modes.
