[vdr] Weird frame rate issue (VDR 1.6 recording, VDR 1.7 playback)
Hi!
Several recordings recorded from JSC Sports (S13.0E-318-500-8440) seem to
have a weird framerate. The recordings were done in PES format with VDR
1.6, so there's no framerate setting in the info file and VDR will use 25
fps by default. This leads to a wrong recording length display (30 minutes
for a recording that was actually 20 minutes long). VDR 1.7.22 is used for
playback and with a small patch I can provide the framerate via the
info.vdr (Which might be a useful feature anyways, patch attached.).
So far so good, but the recording seems to have a weird framerate
This is the recording:
501593483 2012-01-20 13:15:00.0 +0100 001.vdr
366032 2012-01-20 13:15:00.0 +0100 index.vdr
149 2012-01-20 12:55:05.0 +0100 info.vdr
The mtime diff between info.vdr and 001.vdr is 19:55 minutes. index.vdr is
366032 bytes in size, which divided by 8 gives a framerate of 38,29 fps.
Can anyone explain this framerate?
ffmpeg and mediainfo both say 25fps (see below) and VLC tells me it's 50fps.
When I convert the recording to TS using project-x, set the framerate in
the info.vdr to 25 and reindex it with VDR 1.7.22, it still shows the
wrong length.
bye,
Tobias

The media_build repo is a daily snapshot of what you'd get with media_tree (minus the kernel source itself). ___ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr

Hi, The media_build repo contains only backported drivers. Are you sure that the new api changes were backported? The mainstream development happens in media_tree only, which contains a complete kernel snapshot. HTH. Halim ___ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr

Hi,

I have updated my current build taken from the Media Build Tree last Tuesday
with the contents of the linux media tarball dated 22/01/2012 and rebuilt my
drivers.
I still get the same results.
As the system initialises the following lines appear in the syslog:

I'm sure that I have the latest drivers loaded now, but still the same issue.

Yes, I would get to the same conclusion. There should only be one frontend.
You should point the guys on the linux-media mailing list to this "bug".
