Fixes bug #5858 (Render to dv skips frames. OSX and Linux PPC).
Caused by stupid ffmpeg dv multiplexer. PAL-fix is easy, NTSC needs varying
buffer sizes...
Added support for XVid and H264-codecs in codec-selection. (only work, if
ffmpeg is compiled with XVid and/or H264-support. Failure in doing so
results in an error message that codec can't be selected.)
Both are written always to AVIs since raw-h264-files created by ffmpeg
can't even be opened by itself...
Video render options are reset to sane defaults (=DVD preset) on startup now.
Don't expect quicktime-support to be very exciting, since ffmpeg can't really
multiplex quicktime files. (Tried several codecs with the ffmpeg-commandline
tool,... sigh)
Timestamp crash on Debian-Sarge version is fixed.
This fixes again some segfaults on error conditions.
It also gives some reasonable error-messageboxes if chooses the wrong
DV-format-options.
More to come...
Bugfixes:
- hddaudio now allocates it's decode buffer + AVCODEC_MAX_AUDIO_FRAME_SIZE
safety interval. (The former code expected all decoded audio frames to
be the same size which can hurt under some circumstances e.g. VBR files)
- writeffmpeg: some pointers where not initialized on start and after
deletion not set to null. Could segfault randomly on error conditions.
- drawseq: use startdisp and enddisp to decide, if a strip should be drawn.
(Just extend strips first or last frame beyond screen dimensions in
the previous version and watch the strip disappear)
standard for film scanning, 10 bits/channel and logarithmic. DPX is
derived from Cineon as the ANSI/SMPTE industry standard.
DPX supports 16 bits color/channel, linear as well as logarithmic.
Code has been gratefully copied from CinePaint and was integrated in
Blender by Joe Eagar.
According to CinePaint's dev Robin Rowe the DPX code defaults to log
colorspace. Can't find in the code clues yet how to enable/disable that.
However, tests with write/read of DPX seems to show no visible loss by
log conversion code. Might be because it uses the entire 16 bit range...
CinePaint dpx files have been succesfully imported in a Quantel IQ HD/2K
finishing/grading set without problem, so for now I guess we can
use it! :)
Changes in code: added tests for image magic numbers before entering
the actual reading code. Prevents error prints, and makes it faster too.
(Note; this because Blender doesn't check for extensions, but calls
reading functions on every file until one accepts it. :)
- blur works again (this was a serious bug in gamwarp...)
- seperates all sequence effects into a seperate file with a clean interface
- thereby fixing some obscure segfaults
- seperates the scope views into a seperate file
- adds float support to all effects and scope views
- removes a bad level call to open_plugin_seq
- FFMPEG seeking improved a lot.
- FFMPEG compiles with debian sarge version cleanly
- Makes hdaudio seek and resample code really work
