Issue was caused by the change in FFmpeg options: some of them were
renamed, some moved to another class.
Made some tweaks to how options are passed to the FFmpeg which now
seems to be the same as ffmpeg.c.
* Removed audio-only options from ffmpeg render settings (added some versionning code too)!
* Moved the Mixdon button from the Scene->Audio pannel to the Render->Render panel.
Since FFmpeg 0.10 release FFV1 codec supports alpha channel which is getting
enabled when using PIX_FMT_RGB32 pixel format. This leads to incompatibility of
videos rendered in Blender with almost all external players (especially in OSX).
Seems that PIX_FMT_BGR0 is recommended to be used to make videos compatible with
older players which doesn't support alpha channel in FFV1.
Also added an option to switch to RGBA rendering if FFV1 codec is used and if RGBA
rendering is used FFV1 will be using PIX_FMT_RGB32 format which supports alpha channel.
Most part of this commit fixes issues with FFmpeg output with
currently supported codecs:
- avcodec_encode_video might return zero which doesn't mean error
happened, but blender will handle this as error and will stop
rendering to video file.
- Changing output video codec wouldn't update "expert" options
set for video output which leads to some sideeffects like
ignored Lossless option for x264 codec.
This fixes allowed to add QTRLE codec easily.
Issue was caused by incorrectly set PTS value frames came form Scene strip renderer.
This value used to be calculated from RenderData current and start frame which
lead to non-uniformuly counting which totally confuses encoder.
Switch append_avi and append_ffmpeg to use current frame from rendering scene
(which was already passing to this functions and was used mostly for logging)
and start frame of rendering scene (it's new parameter added). This allowed to
calculate correct PTS value easily and get rid of global static sframe variable
in writeavi.c file.
- recode of the whole sequencer audio handling
- encode audio flag removed, instead you choose None as audio codec, added None for video codec too
- ffmpeg formats/codecs: enabled: theora, ogg, vorbis; added: matroska, flac (not working, who can fix?), mp3, wav
- sequencer wave drawing
- volume animation (now also working when mixing down to a file!)
- made sequencer strip position and length values unanimatable
- scene.render_data.frame_path(frame=num), returns the output path for rending images of video.
- scene.render_data.file_extension, readonly attribute, gives the extension ".jpg", ".mov" etc
- player support was guessing names, use the above functions to get the actual names used, accounting for #'s replacing numbers.
* UI layout for scene buttons has quite some changes, I tried to
better organize things according to the pipeline, and also showing
important properties by default, and collapsing less important ones.
Some changes compared to 2.4x:
* Panorama is now a Camera property.
* Sequence and Compositing are now enabled by default, but will only
do something when there is a node tree using nodes, or a strip in the
sequence editor.
* Enabling Full Sample now automatically enables Save Buffers too.
* Stamp option to include info in file is removed, it now simply always
does this if one of the stamp infos is enabled.
* Xvid, H.264 and Ogg Theora are now directly in the file format menu,
but still using FFMPEG. Unfortunately Ogg is broken at the moment
(also in 2.4x), so that's disabled. And Xvid crashes on 64bit linux,
maybe solvable by upgrading extern/xvidcore/, using ubuntu libs makes
it work.
* Organized file format menu by image/movie types.
Added:
* Render layers RNA wrapped, operatorized, layouted.
* FFMPEG format/codec options are now working.
Defaults changed:
* Compositing & Sequencer enabled.
* Tiles set to 8x8.
* Time/Date/Frame/Scene/Camera/Filename enabled for stamp.
Think global, act local!
The old favorite G.scene gone! Man... that took almost 2 days.
Also removed G.curscreen and G.edbo.
Not everything could get solved; here's some notes.
- modifiers now store current scene in ModifierData. This is not
meant for permanent, but it can probably stick there until we
cleaned the anim system and depsgraph to cope better with
timing issues.
- Game engine G.scene should become an argument for staring it.
Didn't solve this yet.
- Texture nodes should get scene cfra, but the current implementation
is too tightly wrapped to do it easily.
Added optional OGG / theora / vorbis support.
(OGG-format encoding is currently disabled, since the bundled ffmpeg version
is broken here)
Fixed a bug with PTS-encoding, to make theora work.
You have to explicitly enable it and currently only scons is supported.
Otherwise: enjoy! :)
Added (disabled) MKV support. Might come handy later, if someone finds
out, why it instantly crashes after 2 frames.
Made it impossible to set min_rate higher than max_rate in render buttons
panel.
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.
