Serviio Stuttering - Fine on PMS
Posted:
Fri May 04, 2012 2:49 pmby WannabeMKII
I'm a recent convert from PS3MediaServer (PMS) to Serviio, as I often had issues with my PS3 connecting to PMS without having to keep restarting the service. Serviio on the other hand, is much more reliable and stable without any issues (hoping I've not now cursed it). However, there is one thing that PMS does well, that I'm sure I should be able to do in Serviio is have a buffer/cache.
The PS3 is connected over LAN and the source plays on Serviio, but often pixelates and/or jumps slightly. Whereas, on PMS, the buffer builds and although it does sometimes empty a little, there's always enough in the 'bank' for it to stream perfectly.
I've doubled the socket buffer from from 65536 to 131072, restarted etc, but it's not helped. Not sure if that was the right thing to change, but a look on the Wiki, FAQ's etc and was hoping this was the solution.
Can anyone assist?
Happy to provide more info if required?

Just to add, the file/s in question, are mkv's.

Can you post the ffmpeg information of the file.
I've had no issues with mkvs on my ps3 with 720p or less, because my ps3 is far from my router it's on wifi, ps3 still got the very slow wifi G so I don't bother streaming big files. This should not be an issue if your on LAN.
BTW: welcome to Serviio, I've learned no more "Unsuppoted Data" on ps3

Thanks for the response and the welcome
Which method should I use to provide the info, as I see there's a couple?

might be due to the transcoder used in PMS. You can compare the ffmpeg (if they use that) command lines from Serviio and PMS.

I believe PMS uses MEncoder.
What can I do to prevent the pixelation on Serviio?
Am I right in what I did with increasing the socket buffer? It's just watching the buffer in PMS, it does fluctuate a bit, but the buffer is big enough to continue streaming without any issues.

The socket buffer is just a buffer of the network protocol. Nothing to do with FFmpeg. Serviio doesn't use any buffer for transcoding. You can try to enable detailed logging, find the ffmpeg command used for transcoding, run it manually and see how many fps it's managing.

No problem, now back to default, thanks for explaining.

OK, I've enabled detailed logging, but now need a little guidance on how to display the number of FPS?

Can anyone help advise on how to find out the number of FPS that ffmpeg is managing in Serviio?

This was on linux for me but this is how I ran a file to check FPS, however this will remux the video. It isn't too cpu intensive though. I was getting 130FPS off of an old Atom Processor.

there will be and ffmpeg.exe -i ............ command used for transcoding in the log. Then run the command in your command terminal and you'll see fps value as it's transcoding

How does that look and does it tell you what you need?

ok, that's fine, 315 fps is more than enough. not sure how to help tbh, might be the bitrate of the remux is higher than whatever PMS is doing.

This is probably due to variable muxrate
[mpegts @ 0237ee20] muxrate VBR, pcr every 2 pkts, sdt every 200, pat/pmt every 40 pkts
Do you have the same problem with this sample ?
http://divxtrailers.divx.com/BigBuckBun ... PlusHD.mkvEDIT:
There is an option "-vsync 3" :
‘drop’ : As passthrough but destroys all timestamps, making the muxer generate fresh timestamps based on frame-rate.

OK, will try that later and let you know.

Sorry, being a bit 'simple' does this mean that it'll force a frame rate and override the variable rate?

Don't really know ?
I make some test, and I'm not sure that this option change something when video is remuxed (-vcodec copy)...
EDIT: Another ffmpeg option seems to modify PCR/PTS Timestamp, you can try
-copytb 1
-copytb mode’
Specify how to set the encoder timebase when stream copying.
‘1’ : Use the demuxer timebase. The time base is copied to the output encoder from the corresponding input demuxer. This is sometimes required to avoid non monotonically increasing timestamps when copying video streams with variable frame rate.
