    New problems in analog radio in latest svn (at least from 272xx).
    Now when changing channels between analog stations the ts buffer file is reproduced always from the beginning (from 0:00).
    This doesn't happen with dvb radio, which works perfectly.
    Everything was working (very very slow channel change) before svn 272xx.
    Analog card (pinnacle 3010ix) with software encoder (ati avivo)
    Logs attached.
    Bye,
    sdf

    Hi again sdf

    This is confirmed, and I'm looking into it. The issue seems to have been introduced somewhere between 27300 and 27350...

    [Edit: found that the issue is introduced in 27301]

    Hi -Manfred-

    Logs attached as promised. Note that the 27301 logs contain the vmr9 log - clearly analog FM is recognised as video...

    Testing process:
    1. Tune to "Life FM".
    2. Listen for 30 seconds.
    3. Change to "More FM".
    4. Listen for ~30 seconds.

    In 27300 the changeover to "More FM" happens immediately (well, channel changing is quite slow, but I think that is a driver issue). In 27301 the changeover to "More FM" happens after 30 seconds of listening to the same section of "Life FM" that was heard previously...

    [Edit: note that my tuners (2 x Pinnacle PCTV 7010ix) are the same as sdf's except that they also have 2 satellite tuners each.]

    Yes, I can see it now why this is not working. FM radio is detected as video because we receive OnVideoFormatChange from TSReader.

    Maybe it doesn't help.
    But the analog.grf is unique both for tv and radio.
    Could it be that is better to split two graphs, one for tv (with video and audio) and another for radio (not connecting the video part in the graph)?
    Don't know if the muxer and the tswriter can cope with it.
    Btw, I've tried a simple graph without tsfilesink and the channel change is lightning fast.
    Thank you,
    sdf

    Update:
    I just committed a fix for the buffer issue. :)
    Channel changing speed is still slow at this time. :(
    Perhaps I can look at switching speed sometime, but I've got too many other things to do at the moment...
