I am probably not describing things correctly (again!)
[with the Xilisoft product, not BatMan]
32000 audio is too fast, 44100 is just slightly too slow (sound lags after 20 secs or so) and
48000 is way too slow, hence I figured if I turned the audio sample rate down a little (which would result in the audio playing faster, hence keeping up with the video), e.g 43900 for example, the audio and video would remain in sync on a Rockchip device at 25FPS. If only standard rates like 44100, 48000 etc are supported, then my idea is rubbish :cry: . I'll move on !
I'll take on board your comments and will try your suggestions.
Keep up the excellent work !!
