I think it may be something related to the file format, many player reports the sample.mkv has same length as the movie.

is there anyone have played yuv444p10le format? no one has encountered this issue?
I think Infuse is using software decoder while A10+ SoC support hardware decoding, because the chip is getting warmer and warmer while I played.

Confirmed that this is caused by Infuse’s software decoder, this file played well using nPlayer on my iPad, and nPlayer supports[1] hardware decode of yuv444p10le.

Hope developers support this colorspace to be hardware acc-ed asap.
