Mpeg4
Earlier tonight I was fast searching 5HD and it seemed faster than before, so i checked the system info diagnostics and it appears that they have
switched to H.264(Mpeg4) Video. I checked some other channels and BBC 2hd, Universal hd, itvBe hd, Film 4hd and BT Sport 3 have switched also. While this is a good thing I have found the 2x search or 30 sec skip is now too fast !.

Re: Mpeg4
I use subtitles, and the 2x speed allows me to watch a programme in half the time. We seem to have lost 2x speed. It goes from play(1x) to 1x(again) to 6x.

Re: Mpeg4
It's so fast it's almost as if it's an error in frame handling and counting.

Wait until they swap to H.265, the compression is insane with that codec.

Re: Mpeg4
Not sure the DVB-C standards include H.265 yet?

Re: Mpeg4
Playing back H264 & H265 videos on my PC doesn't have these problems, so it must be fixable.

Indeed it is
I have x265 (HEVC) copies of many of my TV episodes, and the 1280 x 720 files are smaller than the older 720 x 404 [x264] copies.
(and way smaller than the older xvid format).

Re: Mpeg4
My V6 is unaffected so far. Fast forward was at the usual speed.

Re: Mpeg4
Yep, looking at the file sizes on some of this weeks recordings - some channels (BBC1HD) are around 7-8Gb for an hour's HD, others (BBC2 HD) around 2Gb. I'm guessing the 7-8Gb are still MPEG2 currently, perhaps a staggered change maybe.

Re: Mpeg4
Watching KIRI on Channel 4 last night and FFding through the adverts it went much faster than normal. Is this the H264 malarky?

Re: Mpeg4
It does seem a bit wrong at the moment, pressing the 30sec forward button to 4 minutes to bypass the adverts goes way past 4 minutes, to more like 8 minutes then jumps backwards to correct itself. I hope they sort it out and slow it down a tad.

Is it a problem of handling the situation where MPEG2 and MPEG4 versions of the channel are available and the decoding settings for MPEG2 are used on MPEG4?
