Serviio

Hi,

I've attempted to watch some recordings made on my camera which were recorded in AVCHD format @ 1080P50 that is 1080P resolution captured at 50fps with a bitrate of roughly ~ 26Mbps stored in ".mts" X-264 Container files.

The maximum resolution, frame rate and bit rate for video files in any format on the D Series seems to be 1080P30 @ < or = 25Mbps

Naturally I can't playback the files directly by copying them to a USB memory stick

Serviio is usually able to down-convert video files where necessary but the special decoder for the Samsung D series doesn't seem to reduce the frame rate (and or bit rate) to be compliant within the maximum thresholds of the device.

Please could you include a more comprehensive encoder in the next release (1.2) which can handle the drop in frame rate or at least allow, effectively slow-motion playback of the high frame rate video @ 30fps (as if viewing speed is 50%)

Same issue here. My C7000 does not play natively the 1080P50 files and Serviio does not transcode them in a way the TV can play them.

Thanks.

Here the mediainfo of a file:

I was just looking at transfer rates:

Wired network speeds on a 100Mb/s switch are about 12.5MB/s
1080P50 video encoded in this way is about 25Mb/s which is about 3.125MB/s so it certainly seems plausible from a bandwidth perspective.

To give you an idea of just how much power it uses though, A pc I was recently using with a 9500GT, 4Gb Ram, E7400 etc (which is a little old but not that bad) could not playback the video files. It was badly torn and jumpy, it couldn't handle it.

The main question is to playback in slowmotion or to cut frames? Every second one would need to be removed. I guess it could be done individually converting the videos but it would be a great help if the Serviio were able to conquer it.
