Hi,

the attached vdr-1.5.9-h264.patch adds H.264 support to VDR's remuxer.
The changes to earlier releases are:

- H264::cParser has been enhanced to provide information for
  H264::cContext::GetFramesPerSec() and therefore outsourced
  into separate files.
- cVideoRepacker generates Access Unit Delimiters in case they
  are not part of the stream.

These changes should make VDR ready for the upcoming IFA fair in regard
to the broadcasts on the temporary channel EinsFestival HD.

The other attached patch vdr-1.5.9-framespersec.patch tries to replace
the macro FRAMESPERSEC by a function call GetFramesPerSec() which
analyses a recordings first video frame to determine frames per second
which are used to calculated a recordings length. The changes to earlier
releases are:

- add support for H.264 recordings by making use of the above
  mentioned H264::cParser, as frame timing stuff is quite complex.
  H.264 support can be turned off by putting a comment around the
  macro ADD_H264_SUPPORT in tools.c.

This change provides correct recording length reports for recordings
taken on EinsFestival HD as this channel broadcasts 50p, i. e. without
the patch, VDR will report recording times which are twice the actual time.

The patch in general may especially be useful for people with PAL and
NTSC recordings, as in this scenario it was never possible to find a
single setting for FRAMESPERSEC.
Although FRAMESPERSEC has been replaced on many locations, it is still
used to read/write cutting marks file, to stay compatible.

Have fun while expecting the next vdr-xine-release ;-)

Bye.
