Loss of Frames in second movie

Post by solamnic »

I playback from my NFS Server running on Gigabit LAN (windows 10 - hanewin nfs server)

When i playback any first movie everything is fine i can move to any part of the movie with no problems.

After that i start a second movie.

Playback is ok BUT if i move to another part of the movie after 1 h problems start.

I have loss of frames.

If reset apple tv and start the second movie i have no frame loss.

Using AV Codec

Using AVF I often see this on h264 material. A skip or restart from long pause will result in a slow motion look.

Davilla has said that AVF isn't very good with h264 compared to VTB and I think these instances are what he's talking about.

yep, it does compared to AVF. With VTB I use contrast 46% to bring back whites.
