I have php 5.1.6 running on my CentOS 5 server running Apache 2.2.3
I installed ffmpeg library and my aim is to covert a set of images into a slideshow with the fadein/fade out effect per image swap.
Command ffmpeg says:
`FFmpeg version SVN-r26402, Copyright (c) 2000-2011 the FFmpeg developers

Use -h to get full help or, even better, run 'man ffmpeg'
and command ffmpeg -filters prints:

Filters:
anull Pass the source unchanged to the output.
anullsrc Null audio source, never return audio frames.
anullsink Do absolutely nothing with the input audio.
copy Copy the input video unchanged to the output.
crop Crop the input video to width:height:x:y.
drawbox Draw a colored box on the input video.
fifo Buffer input images and send them when they are requested.
format Convert the input video to one of the specified pixel formats.
gradfun Debands video quickly using gradients.
hflip Horizontally flip the input video.
noformat Force libavfilter not to use any of the specified pixel formats for the input to the next filter.
null Pass the source unchanged to the output.
overlay Overlay a video source on top of the input.
pad Pad input image to width:height[:x:y[:color]] (default x and y: 0, default color: black).
pixdesctest Test pixel format definitions.
scale Scale the input video to width:height size and/or convert the image format.
setdar Set the frame display aspect ratio.
setpts Set PTS for the output video frame.
setsar Set the pixel sample aspect ratio.
settb Set timebase for the output link.
slicify Pass the images of input video on to next video filter as multiple slices.
transpose Transpose input video.
unsharp Sharpen or blur the input video.
vflip Flip the input video vertically.
buffer Buffer video frames, and make them accessible to the filterchain.
color Provide an uniformly colored input, syntax is: [color[:size[:rate]]]
nullsrc Null video source, never return images.
nullsink Do absolutely nothing with the input video.`
firstly my ffmpeg was not having fade filter because it was giving error
fade: filter not found
so i installed the patch created vf_fade.c and made corresponding changes to Makefile and allfilters.c file of directory libavfilters in ffmpeg. configured it again then also ran commands ‘make’ and ‘make install’ Restarted the server but still its showing the same error
fade: filter not found
what should i do next? if any more details needed please ask and all the helps and ideas and links will be appreciated.
Do you really need ffmpeg?
It sounds like you could achieve the same effect, maybe even better, just using javascript. Have a look at jQuery’s fading API and see if that would be enough to do what you want.
