Creating a DirectShow Filter for live video/audio stream analysis (black/frozen, silence), writing events to text log file
$750-1500 USD
Pagado a la entrega
I need a DirectShow Filter created that does the following:
1) Analyses live video stream for black / frozen video. It can, for example, save a frame in buffer every few seconds, then compare frames. If identical then change log file.
2) Analysis the same video stream's audio track for silence. It can work similarily with the video analysis - save some samples, then analyse them. If they are with lower-than-treshold dB's, change the log file.
3) Keeps a text-based log file that basically has the live status of this stream. It would be nice to be able to change (in the DS Filter properties) the name and location of this status log file. Example of such log file contents ("NO" changes to "YES" when the problem is active in the video/audio stream):
VIDEO_BLACK|NO
VIDEO_FREEZE|NO
AUDIO_TRACK1_SILENCE|NO
AUDIO_TRACK2_SILENCE|NO
This DirectShow Filter needs to be constructed as follows:
1) Has to have a possibility to add an input - demuxed video/audio stream.
2) Possibility to analyse a stream with multiple audio tracks.
3) Has to have GUI/config file for changing the configuration of the filter.
4) The DirectShow Filter device doesn't need to output the video streams anywhere.
5) Like already mentioned, writes status log file all the time (like, updates status of each of the elements (BLACK, FREEZE etc.) every 10 or so seconds).
P.S. All of the tresholds for freeze/silence etc. detection have to be configurable. Also, multiple instaces of this DS Filter have to be able to be run simultaneously (of course, in different GraphEdit graphs).
