[theora-dev] Manually Change Quality value of each frame
Hi All, I have set *cpi->pb.ThisFrameQualityValue* parameter to* 10(minimum value of the ac scale factor matrix) *manually while compressing in CompressKeyFrame and CompressFrame functions in encoder_toplevel.c. As we were expected, size of the encoded ogg video increased. But quality of the was not increased (It's quality has been degraded). Can anybody explain the reason for this? In Decoding process, is it only consider about the quality value of the First Frame rather than considering the quality value of each frame? -- Nuwan Millawitiya -------------- next part -------------- An HTML attachment was scrubbed...
