Well, I've spent some time with subtitles. Will switch to 1.5.11 this
weekend and supply new patches.

That's OK with me. As I wrote earlier, feel free to contact me when you
think about taking over the patches.

Actually, we are not asking for decoding H.264, as there are no patches
necessary to VDR regarding decoding. Decoding is handled either by
FFmpeg-svn, xine-lib-1.2-hg and vdr-xine-0.8.0 or by a HDe and the
reelbox plugin. Both decoding and display solutions don't need VDR to be
patched.

The most relevant patch to VDR enhances the remuxer to extract the
picture type of H.264 frames. This part is sufficient to record H.264
broadcasts on DVB-S and DVB-C.

Then there is the part which adds DVB-S2 support to VDR (provided by
Marco Schlüßler). Sure, this one is a bummer as one needs to use the new
multiproto DVB drivers.

The remaining parts (syncearly, framespersec) support H.264, but are
also useful for MPEG2. One provides faster zapping and the latter will
make VDR show correct recording lengths e. g. for NTSC recordings.

So to sum up and refer to my previous post, there is no need to watch
H.264 on a PIII 450 MHz (although this should be possible with a HDe),
but even this machine would be able to record H.264.

Bye.
