MVP skip/jump FWD/REW does opposite or nothing (quite often)

[pvruser]

It's odd but since i started using the MVP somewhat more i noticed that the remote keys for skip & jump FWD/REW sometimes do the opposite or do nothing or work just fine. the funny thing is that i see the timeline indicator on top of the screen changing time but the video does not (in the cases where no skipping at all happens).

is this common or just my issue? the remote has 34 keys & i use the ffmpeg for transcoding (pretty much the standard settings):

<MVPFFmpegTranscodeCmdLineNTSC>-y -i "{SOURCE_FILE}" -b 2400k -ar 48000 -ac 2 -r 29.97 -s 352x240 -f svcd "{DEST_FILE}"</MVPFFmpegTranscodeCmdLineNTSC>

Are these .mpg files you're playing? If not, then all bets are off. The MVP only plays .mpg files natively. Anything else requires on the fly transcoding, and simple playback is about the most you can expect to work - skipping etc is hit or miss. If you want it to work more reliably, you need to convert the files .mpg before you try playing them on the MVP.

i'm using the forced ffmpeg on the fly transcoding (from avi and HD mpegs). since there is a temporary mpg file created MVP0000000000002.mpg i would assume that the skipping would work fine. both the original and temp file play ok on the PC.

other than keeping a directory of mpegs (although i dont quite see why since the temp file is already mpeg) is there a solution for this?

also want to add that even after the MVP transcoding was complete on the PC, the skipping was not correct.

Sorry, as mentioned above, all bets are off when its having to do on-the-fly conversions to .mpg. All you can do to improve things is convert the videos to .mpg before playing.

OK it's fine i can live with it considering how much i'm watching the MVP... my other question is will the same things happen with the PCH when i do on the fly transcoding? or does the PCH play every format without transcoding so the issue does not apply? asking because i intend to buy a PCH and use it along with my MVP and GBPVR.

Thanks!

It doesnt do transcoding on the PCH. It can play a much wider set of media formats.

ok sounds great! i'm still amazed though and cant get over the fact that the MVP logs where the command says "skip forward" the index set is actually before the current file index... multiple times!

Your post in another thread made me understand the problem better. You are transcoding all mpegs to deal with digital broadcast so you are going from the broadcast stream to ati mux to ffmpeg to transcoded mpeg. You should be lucky it works at all.

yes you got that right. i have to transcode it because the MVP can't play HD video... so any avi or mpeg file goes through ffmpeg and to the MVP. i thought avi files HAVE to go that way anyway. the thing is that the file (or the part i'm trying to jump to) is already transcoded on the disk when i make that jump request. even after transcoding finishes for the entire file i get the same result of random skipping.

i understand there's a problem with (on the flu) transcoding, i just don't see why if a mpeg file (even a transcoded one) already exists is played fine but one that just got created by the same ffmpeg does not work.
