handheld theora video camera wish list
What would your wish list be for a handheld theora
video camera?

Record to a memory card (SD)
Lan / WIFI support (auto/manual upload of file on
memory card)
Live streaming (icecast like)

Encoding speed
I tried to encode two minutes from an AVI DV file 720x480:
ffmpeg latest release produces a FLV 320x240 25fps 360k video 40k audio in about 45 sec.
ffmpeg latest release produces an OGG 320x240 25fps 360k video 40k audio in about 1:20 sec.
ffmpeg2theora the same in about 2 minutes or more.
The FLV quality it's quite good, some dropped frames maybe.
I was wondering to know if ffmpeg team it's usi...

libtheora 1.1 problem? with firefogg and ffmpeg2theora
hi all,
i have been trying to export some videos using firefogg in two pass mode. the problem i get recently with various files is that when i choose a low bitrate (for example 1200kbps for a 512x224 25fps video with so many details) the video quality is very very good at the beginning (much better then my quality based -v 5 export which produces a 1204kbps video with the same build) and then the pixel blocks get bigger and bigger towards the end of the video and at the end they become very very big...

super-low 19.5KB/s theora videos
I am only able to get streamable videos at 19.5KB/s (156kb/s) due the transcoding and streaming from the mythtv setup over 900Km away
the videos on the mythtv setup are 352x288 interlaced at 25fps at 524KB/s and the audio is 48000 stereo at 128KB/s
What are the best setting for 19.5KB/s (156kb/s) theroa video stream?

ATI/AMD GPU + Ubuntu + Wine + EVE Online = I need help...
...things work as described below. This applies to source and packaged.
For the most part, everything works. But only barely.
Under Windows, EVE runs at 140+ FPS, churning a hard 60-85% CPU usage across all cores. (She's quite a CPU hog, sheesh!)
On Linux, under Wine though, EVE can't break 25FPS, and barely ever touches in at 25% MAX across all cores.
Now here is what I am having trouble identifying. I am aware that ATI/AMD's drivers are not all that, but I'm not too sure this is indeed the problem. How come the CPU usage is so low under Wine?
Within EVE, the monitor indicates 100...

Granule pos bug ?
...d Size : 43
Data Size : 2311
Page Size : 2354
Num Packets : 10
<p><p>Notice on the second shown page (seq no 12) the granule pos is the same as the page before instead of -1... also notice on the next page (no 13) the granule pos is now 4104... the video is only 40 seconds long @ 25fps ~= 1000frames.
And by the last page of the video bitstream the granule pos is way up to 81225.
Anyone have any idea what could have caused this ? And what is the correct way to indicate no packets end on a page ? Is it -1 or the same as the previous page...
Cheers,

Encoding - CPU usage ...
Hi all.
I would really like to use Theora for the commercial product I work on...
It's a Linux based DVR. Actually we use ffmpeg to produce MPeg4 short
clips from 4 BNC channels in CIF resolution.
I made a small module for our project that uses Theora... but I see that
it gets a lot of CPU :(
So I'm here to ask for any kind tips to reduce the CPU usage.
- Hardware... do you think there

Theora hardware is running on LEON3!
Theora hardware with LEON3 is runinng!!!
My video was too slow, then I discovered that the problem was on LINUX!
I don't exactly, but I suppose that the time of LINUX Call systems (like
fread()) is the problem. If I don't use the linux (like is done on NIOS), I
can to decode much faster than the time of exibition!
Now we have two points on software (the hardware is the same,

Best Way to Import HC-X800 1080 60p/50p MTS to iMovie HD
...OV conversion, you can adjust
video and audio profile via clicking “setting” icon. If you want to get
a smaller MOV file, you can click triangle icon and you will have
several options to decrease the video size.
Tips:
It is recommended that 1920*1080 as video size, 30fps for users in NTSC
area and 25fps in PAL area as video bitrate to achieve high video
quality.
Step 4: Start convert 1080 60p/50p MTS to iMovie HD on Mac
At last, click the "Convert" icon to convert and transcode Panasonic
HC-X800 1080 60p/50p MTS to AIC for iMovie HD.

OpenGL context switching with Noveau
For details see my presentation on day 3 of XDC2016. TL;DW: A context
switch on average takes ~25 microseconds, but depending on the display
resolution and the load on the card times up to 130 microseconds have
been observed. The average does not appear to differ much between cards
as the (growing) size of the context is in balance with the increased
DRAM bandwidth. Measured worst cases
