[mythtv-users] Video playing at 30fps

[Andrew Wilkinson]

Hi,

Since upgrading from Mythbuntu 12.04 to 14.04 I've had the issue where if
booted without the tv being on then there is no signal when the tv is
switched on. I've resolved the issue by disabling xfsettingsd and running a
script that calls xrandr on hdmi connect. There is one remaining issue, and
that's that after my script uses xrandr to turn on the screen MythTV plays
all recordings at 30fps, making the sound higher pitched than usual. If the
tv is on when the machine is booted the recordings play at 25 fps as usual.

Here is the xrandr output when the TV was on when booted:

Screen 0: minimum 320 x 200, current 1360 x 768, maximum 32767 x 32767
VGA1 disconnected (normal left inverted right x axis y axis)
HDMI1 disconnected (normal left inverted right x axis y axis)
HDMI2 connected 1360x768+0+0 (normal left inverted right x axis y axis)
160mm x 90mm
   1360x768       60.0*+
   1920x1080i     60.1     50.0     60.0
   1280x720       60.0     50.0     59.9
   1024x768       60.0
   800x600        60.3
   720x576        50.0
   720x480        60.0     59.9
   640x480        60.0     59.9
   720x400        70.1
VIRTUAL1 disconnected (normal left inverted right x axis y axis)

And here's the start of the frontend log with -v playback, also when the TV
was on when booted.

Here is the xrandr output from when the TV was turned off when the machine
booted:

Screen 0: minimum 320 x 200, current 1360 x 768, maximum 32767 x 32767
VGA1 disconnected (normal left inverted right x axis y axis)
HDMI1 disconnected (normal left inverted right x axis y axis)
HDMI2 connected 1360x768+0+0 (normal left inverted right x axis y axis)

   1920x1080i     60.1 +   50.0     60.0
   1360x768       60.0*+
   1280x720       60.0     50.0     59.9
   1440x576       50.0
   1024x768       60.0
   1440x480       60.0     59.9

   720x576        50.0
   720x480        60.0     59.9
   640x480        60.0     59.9
   720x400        70.1
VIRTUAL1 disconnected (normal left inverted right x axis y axis)

And here's the log with -v playback from when TV was off during boot.

As you can see in the second of these log outputs it is playing the video
at 30fps, but earlier it correctly detects that the video is 25fps. Why?
What can I do to get it to play at the correct speed?

Many thanks,
Andrew
