iPhone 4 videos stutter

Hi,

I've just stumbled across serviio and it looks great so far, its the best working DLNA server that I've found to work with my Sony BDP-S370 (and I've tried a few!).

My question is why do videos that I've shot on my iPhone 4 really stutter on play back on my blue ray player?

I'm new to this world of video formats and from what I can figure out the server isn't transcoding as the video kind of plays with it on or off.

I've downloaded a hd divx trailer and this streams perfectly so I don't think this is down to the server resources (also the CPU usage is low).

Does anyone have any ideas as it would help me out greatly!

Thanks
Matt

What is your video format? Could you please make a "ffpmeg -i" of it.

Hi,

Thanks for the reply, here's the output:

Which version of ffmpeg did you used?
I'm not a linux user, but I think you may try to compile source code of ffmpeg given in this link
"This release includes FFmpeg (rev. 23013, incl. a patch)"

HI,

I'm using this version:

FFmpeg version SVN-r0.5.1-4:0.5.1-1ubuntu1

I'm not sure how to compile the version on this site, are there any instructions anywhere?

Thanks
Matt

in the readme.txt distributed with the sw

ta - really should have looked inside

[zip]

anyway, FFmpeg will not be the cause of the stuttering in your case, as the video is not transcoded. It might be that the player doesn't like the encoding... I guess the bitrate is no too much for the network to cope

cool - didn't relish having to compile it!

The network shouldn't be a problem as the server and player are wired into the same router.

Is it worth transcoding it into something else?

[zip]

maybe..

looking at the ffmpeg output again, it's a HD video, 10MBit/sec ... are you sure the player can play this king of bitrate? It should be ok, just checking.

not sure what it can handle, I'm trying to find out.

I managed to place a HD divx trailer (ffmpeg doesn't show a bit rate) without issues.

You can see the bitrate displayed on the TV when you play a clip if you press the i+ button on the remote. It ought to be ok with 10Mbps because I have a test clip in 720p@60fps that hits around 15Mbps with no stutter.

Actually, I just remembered that although MOV files (very similar to MP4) are recognised by the player I found that they stuttered unless transcoded to M2TS. This has the added advantage of supporting FFWD/REW which is not permitted by the player for MP4.

Thanks, I did that and its around 10mbps (I forget exactly) but in the top right there is another bit rate and this is about 70kbps which doesn't seem a lot...

I edited my post above - are you playing the mov natively, or is it transcoding to m2ts? And what happens if you try to play it from the USB port directly?

Sorry, just saw the edit. Tried it and it fixed it! Genius, many thanks!

[patters]

Cool. If I recall, MOV playback was dodgy from USB too so I think it's an issue with the player rather than Serviio.
