Video Pre-Frame Caching Architecture.

 

F

inally, first 64 bit development of Shira Player is completed. In this version video playing architecture was changed completely. Qt and FFMPEG library versions were upgraded to last ones.

Henceforth, it will be using "Frame Caching Architecture" for video playing. Now, up to 3K videos can be played without any drop frames.

What is the Pre-Frame Caching Arch.?

Old versions of the Shira Player were experiencing drop frame problems over 1K videos. To solve this, frames of the first second (it is usually 30 frames) buffered in the memory. As soon as first second of the video is prepared, it begins to play. Thus dropped frame problems will be eliminated. Of course this can be related with videos bitrate and resolution. In addition to save play as stable, Shira Movie Encoder software was developed by using power of FFMPEG. It encodes image sequence or transcodes different codec movies to stable bitrate and fps movies.

In this version and next, Shira requires splitted video and audio files. The Shira Movie Encoder also provides this operation.
