Sorry for the top-post, unintentionally. The high thread count caused significant quality reduction with older ffmpeg/x264 encoders. I'll run some tests with the newer versions and post the results.
In most cases there is no reason for multi threaded decoding. On the other hand 4 threaded x264 encoding runs 2.5-3 times faster than a single threaded encoding, assuming that there are enough free CPU. With 4 threads the quality insignificantly lower, almost invisible. Unfortunately, I did not keep the PSNR results. _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
