Experimental TsReader development (7 Viewers)

[Owlsroost]

since the area51 thread is closed, I´m posting here.

Got a black screen on channel change using the area51 tsreader. Logs attached. Channel NRK3 on at 20:09:25.

Does it happen every time with this channel ?

If not, can you post some logs from when it works OK ?

(It's timing out after 5 seconds in the initial stream reading section and never finding the correct video data, so MP thinks it's a radio stream......)

Try noStopMod50 -> here <-

Various H.264 header parsing, media sample PMT info, NALU start code detection, sample queue locking, video/audio 'slow motion sync' experiments/mods/fixes.

Tony

Does this include the changes of "v0_4_17a from -> Area51 <-", too?

The "TsReader_0_4_17a_black_screen_and RTSP_fixes2" version does very well for me! First one with having no problem watching TV, after watching a BluRay (and switch Framerate)...

Yes (in fact the fixes went from the 'noStopMod' versions to v0_4_17a).

Tony

well, did v50 a short try: Stutter for several seconds after channel change (PDVD11)
went back to v0_4_17a : Fine!

I'm on the road for some days, so I don't have time to make logs now...

The stutter on video at the start may be the 'slow-motion' sync feature - see https://forum.team-mediaportal.com/...reader-development.102693/page-52#post-847873 - for instructions on how to disable it.

This is also in v0_4_17a and older versions but it doesn't work correctly in those versions.

After short testings i´m back to v048. v50 gives me slow channel change [ using UNC ]. Has v050 the registry stuff from v048 ?

Yes.

Can you post TsReader logs for v48 and v50 with the same channel change ?

There has been a change in when it adds PMT sample info to the decoder - it now does it on every channel change, instead of just when TsReader is first loaded. Try setting the 'disableAddPMT' reg key to '1' and see if it's any faster.

I will try it today evening again and will post up the logs. I had a quick check, but does not found something interesting.

OK latest version seems to work well with MS codec for SDTV and PDVD12 for HDTV.

Using PDVD12 for SDTV with this tsreader gives massive stuttering after channel change for about 30 seconds.
Using MS codec for HDTV gives flashing picture (picture / back / picture / black) after channel change.

Cheers.

Logs ? System specs ?

Are the SDTV and HDTV MPEG2 or H264 ?

Damn system spec have gone since switch to new forum which I didn't notice.
Sorry for that.

SDTV is MPEG2
and HDTV is H264.

Cheers.
