What exactly is threadsafe
Hey I am playing with a LOT of threads right now, and I want to know if the
threads all need their own little vorbis encoders running in them or what
exactly is threadsafe in vorbis?
So here are the functions that would be called from many threads of with
buffer = vorbis_analysis_buffer( &m_vorbisDsp, 4*DATA_CHUNK_SIZE );
vorbis_analysis_wrote( &m_vorbisDsp, dataLength/dataSize );

Can a libFLAC encoder be initialize and called from inside a libFLAC decoder callback?
I am getting large, corrupted native FLAC files when trying to call the
encoder from inside the decoder. The metadata in the output file is OK.
Is initializing and calling an encoder from inside a libFLAC decoder write
callback supported? The encoder is initialized on the first write callback.
Environment is Win 7 Ult, 64-bit, VS 2008, libFLAC 1.2.1.
Here is some context. The static

Can a libFLAC encoder be initialize and called from inside a libFLAC decoder callback?
Have you tried decoding to memory, and encoding from that memory?
This technique would avoid file I/O.
If you are reluctant to allocate enough memory for the full file (and
why not, with a 64-bit system?), then you could implement a FIFO.
You would need a semaphore to keep track of the decoder's progress,
and multithreaded coding. The decoder would pause, whenever the FIFO
gets

ogg_stream_pageout(): Weird Documentation (libogg-1.0).
Hello!
Can someone tell me, what the return value of ogg_stream_pageout()
_really_ means? Documentation (libogg-1.0 - 20000615) says:
...
Return Values
0 means that there is not enough data yet to form a page.
0 means that the page was successfully submitted to the bitstream.
...
Thank You very much!

[?] About YUV format
Hello. I read documentation, but I didn't found anything about encoder
supported YUV format. Is Y in [0-255] or in [16,235]? And U,V are in
[16,239]?
I'm trying to write a fast (with lookup) conversion from RGB -> YUV...
Thanks in advance,
Andrea

libtheora 1.1beta2 release
I've put up a second beta for testing. libtheora-1.1beta2:
- Improves rate control with difficult-to-encode input (the huskies issue)
- Has all the example code ported to the 1.0 api
- Builds on OpenBSD and Apple Xcode
- TH_ENCCTL_SET_SPLEVEL is work again for trading of encode speed
for quality. There's now a TH_ENCCTL_GET_SPLEVEL as well for reading
the default/current

[?] About YUV formats...
Hello. I'm a theora newbie... I see it accept video frames in some
differents YUV formats.
How theora manage them internally? I mean: if i encode the same video twice,
first time encoding it with YUV444 packets and then with YUV420, will second
video be smaller than first (due to subsampling...)? Or theora compress them
in the same way?
Thanks in advance,
A. F.
