DVB-T AVC/h264 MPEG2-TS live remux

[lif]

Hello!

Our DVB-T service provider here broadcasts MPEG2-TS streams consisting of h264 video and mpa audio. GBPVR is able to record it OK and muxing only one channel into .ts file. Fine for recordings, but a little bit not so fine when playing it on PC client(s). Some why when playing back this .ts using PVRX2 UI on Pentium-M 1.4GHz laptop, it consumes about 98% CPU and A/V is going out of sync. But when for example remuxing this .ts into .mkv the CPU load on laptop client is about 50..70% and A/V is in sync.

So, question is, how to remux AVC transport stream into avi/mp4/mkv in real time when gbpvr is still recording the show. I guess that this could be done using parallelprocessing.bat and ffmpeg.exe or mencoder.exe, but there are two issues:

a) how to tell gbpvr that right after it has finished .ts recording from DVB-T (or from IPTV), point to remuxed container in gbpvr db?
b) what would be the right syntax for ffmpeg to remux .ts into another supported container (I haven't figured out this yet, as every try I've made I had some errors concerning some mysterious .ts timing errors)

So, any ideas, any help?

a) Although I've never testing it with TS files, typically if GBPVR cannot find the video file, it will check for the corresponding AVI or MKV file (possibly MK4 as well). This only works if you're running the GBPVR frontend on the server machine. If you're running a separate GBPVR client or a media extender like the PCH then you'll need to change the name in the database. The only way I'm aware of doing it is by getting the sqllite3.exe command line app and changing it that way but you need to be aware of shows that contain question marks.


I'm also not sure if ffmpeg supports h.264 video in a TS container. I've have much success with demuxing MPEG2 video from a TS container though.

You could try dsmux.exe from the haali splitter. That's probably the only other app that can mux from TS to MKV in one step.
