    Re: Video stuttering: messages about RingBuf, waiting for data

    Problem solved. One problem was that the raid-array was to slow when writing. I swapped first to a SSD and now to a singe hard drive (not raid) and that solved a part of the problem.

    Some days ago I updated MythTV and my feeling is that the update made some changes in a positive way. The problem is now minimized.

    Re: Video stuttering: messages about RingBuf, waiting for data

    Since last time I posted in this thread, I have taken a few steps forward and some step backwards.

    Now I have a singe 2TB harddrive storing both MythTv recordings and live TV.

    MythTv has been updated to v0.26.0-64-g637d6d8 some days ago. Stuttering in live Tv has nearly vanished, it appears sometimes, mostly on HD channels.

    After upgrading to v0.26.0-64-g637d6d8 recordings are now the victim for worse stuttering than ever before - I cannot watch recordings any longer.

    I also having trouble with channel locking. Something is happening sometimes when I am leaving live TV mode or not watching live TV for a couple of hours. After that something has happened, channel locking cannot be done any longer, I have to restart the backend computer.

    Re: Video stuttering: messages about RingBuf, waiting for data

    Now I made a short recording which stutters enormously. Below are a section of mythbackend.log where the recording took place.

    Watching LiveTv is normal, watching a live Tv recording is also normal.

    Re: Video stuttering: messages about RingBuf, waiting for data

    Sorry for this. You made me check my adapters. I have four of them.

    Watching Live Tv is using adapters in the following seuqence 1,2,3 and 4. While recordings are using adapters in the following seuqence 4, 3, 2 and 1.

    Swapping live tv adapter in frontend to adapter 4 revealed why recordings are stuttering, the fourth adapter is faulty, probably due to a bad connection to my sat dish.

    Re: Video stuttering: messages about RingBuf, waiting for data

    Now I have located and fixed the bad cabling. It is working much better now

    However, when watching HD channels live on two frontends simultaneously as I am recording two HD channels makes live TV stutter sometimes.

    Here is the ringbuffer information message. It is a lot of them. Can they have something to do with the stuttering? Or something else?

    And what are the ringbuf (WaitForAvail) meaning in a technically point of view?

    Re: Video stuttering: messages about RingBuf, waiting for data

    There are a lot of ringbuf i my log now. Only watching one HD channel now. No stuttering.
    Is curios about what this ringbuf really means. Is it related to hard disc IO or is it related to the DVB device, reading from the DVB driver etc?

    Code:

    Hi Erik-na did you ever resolve this I have exactly the same symptoms, video stuttering when watching HD channels and same Ring buffer logs on the backend

    The problem was solved after I changed to better cabling from LNB to my DVB-S card. I also swapped to a bugger dish which increased both signal level and snr.
