Camera Viewer App (Cam View) / News: Recent posts

The primary motivation is to render 4k video. It seems to be very demanding for resources.
A new version of CamView 2.3. detects presence of MMX unit and can use vectorised CPU instructions for some operations. This can decrease CPU load a little bit. Some time critical functions are embedded in wx widgets library and they are not accelerated yet.
This feature has been introduced in pictures library version >=2.81. ... read more

All video modes reported from AV video generator could be rendered by CamView from version 2.2.4. See the image.

CamView 2.1 can display and analyse camera framerate, see attached image. There are available 32bit and 64bit binary variants, they should be functionally equivalent.

Please note tremendes performance boost due to code optimisations, CamView now consumes 8% and previous versions consumed 36%

Nobody noted and or reported that load image stopped to work. Now it is working again.

A new possible crash has been found in x64 port. This problem looks innocent, but can potentially cause random unexpected crash: https://sourceforge.net/p/wp2latex/wp2latex/ci/a9e3f4f4f2f0a593a45964d167a87293e959d36b/

32 bit port is here for more than 10 years, but 64 port is still relatively new.

A new bugfix release 2.0.3 is available.

Anyway, ussing assembler is critical to push CPU load as low as possible. It is much more better when CamView with eunning camera consumes 5% of CPU and not 50%.... read more

I have posted CamView 2.0.2 that contains fully 64 bit version. . It has a same API as 32bit version. 32bit and 64bit versions could be installed simultaneously (on 64bit machine of course). There are bugfixes in histogram calcullation for some obscure videoformats.

Please upgrade to 2.0.2 or uninstall 2.0.0 and 2.0.1 betas, they have unpleasant bugs.
