Re: [Freevo-users] freevo 1.8 memory usage when viewing images

2009-02-20 Thread Duncan Webb 
On 19/02/2009 10:16, Olivier Sessink said the following:
 Attached is a patch that should reduce the memory and speed up the
 display of images, it may not be 100% correct yet (lack of rotation and
 using the thumbnails for the full image).

 The thumbnails can be generated with the helper mkimagemrss and the
 size of the thumbnail can be controlled with: WWW_IMAGE_THUMBNAIL_SIZE.

 The patch applied to 1.8.3 with some fuzzy offsets.
 
 it is a good improvement.I don't get into problem with the
 out-of-memory killer anymore on my 512Mb box. Memory usage is now
 around 80% when listing a directory with photo's. Do you want a
 comparison with the 1.7 series (where I never had any memory
 problems?)

No don't need the comparison with 1.7 as kaa.imlib2, which generates the 
thumbnails wasn't used then.

I did notice that all the images are cached for later use but didn't 
check when they are freed from the cache. Of course caching big images 
would cause a memory problem.

It should be a lot faster too, it takes quite a long time for imlib2 to 
process a large photo (3072x2048) about 1.5 secs on my P3 box which is a 
performance killer.

Re: [Freevo-users] Handling usb foreign drives

 Hey all,
 
 Does anyone have a Freevo solution where I can connect an
 External hard drive, USB key whatever and Freevo would be
 able to navigate it.  The automount stuff is easily enough
 done but the issue I run into is Freevo has the idea of
 audio_items and video_items where the directory would be
 linked in.  On a foreign drive though, we don't know in
 advance what will be on it, music movies, pictures etc.  Is
 there any setting whereby Freevo will just launch the
 appropriate playback method and not care where the
 directory is categorized?

I have solved this the following way:

1) Install the usbmount program
2) In /etc/udev/usbmount.rules (might vary on your distro), insert:

-- snip --

# Rules for USBmount

KERNEL==sd*, BUS==usb, ACTION==add,RUN
+=/usr/share/usbmount/usbmount add
KERNEL==ub*, BUS==usb, ACTION==add,RUN
+=/usr/share/usbmount/usbmount add
KERNEL==sd*, ACTION==remove, RUN
+=/usr/share/usbmount/usbmount remove
KERNEL==ub*, ACTION==remove, RUN
+=/usr/share/usbmount/usbmount remove

-- snip --

3) Restart udev
4) Make sure you have in /etc/usbmount/usbmount.conf: FILESYSTEMS=ext2
ext3 vfat to allow fat partitions to work AND:
MOUNTOPTIONS=sync,noexec,nodev,noatime,ro to mount al devices
read-only, or data loss could happen, since you won't be able to unmount
devices cleanly with freevo

5) Then you can add in your freevo's local_conf.py on the
Video/Music/Images section something like: ('External
Storage','/var/run/usbmount/')

Then if you plug in your usb key, a new folder should show up
in /var/run/usbmount/, and if you go to Video/Music/Images on your
freevo system and select External Storage on them you will see the usb
key and files.

Hope this helps.

Cheers,
Benedikt

kaa.imlib2 has two layers of cache: one for uncompressed data (16MB),
and the one built into imlib2 for compressed data (4MB).

The uncompressed data cache can be tuned:

   kaa.imlib2._image_cache['max-size'] = number of bytes

Now that I look at the code, max-size is a bit of a lie.  It will
actually cache one image, even if that image exceeds the max size.  So
an extremely large image (3072x2048 in your example) will actually use
an extra 24MB of memory.

You can, however, bypass the uncompressed image cache by using
kaa.imlib2.open_without_cache()


 It should be a lot faster too, it takes quite a long time for imlib2 to 
 process a large photo (3072x2048) about 1.5 secs on my P3 box which is a 
 performance killer.

beacon uses epeg (which is nowadays merged with evas, but beacon still
has it split out), which is probably the fastest JPEG thumbnailer
around.

Not prefect, but then this is  a hard job for a prefect solution. It
does however make a really good answer to teh problem as you should
know what is on the media :)

Beacon's epeg code is around 4 times faster than imlib2 (so my changelog
says). And it looks even faster since beacon is doing all the stuff in the
background and you do not have to wait.

[Freevo-users] Blank screen after seek w/ mplayer in 1.x SVN

2009-02-20 Thread alhaz 
Recently updated my tired old debian box to lenny and in the process  
threw out my freevo 1.7.

I'm now using freevo 1.x from SVN (perhaps foolishly, because i plan  
to try to use the livepause plugin, which the wiki still says is only  
in svn) and have rebuilt ffmpeg, mplayer, etc - also from their  
respective repositories.

If i seek forward or back with the ir remote, the video goes blank a  
second or two after seeking. If i use the keyboard at the console to  
seek, it works fine. The secreen only goes blank if I've been using  
the remote.

Any ideas?
