DVB-T (h264) mux streaming makes corrupted output
Posted: 14 Sep 2011 11:08
Hi,
I try to stream some channels from local (hungarian) dvb-t reception, but I have problems with it. The whole mux dump can be played without problem, like the live reception. When I seperate the channels to streams the SD (720*576i, HP@L3) channels get corrupted. The HD (1440*1080i, 1920*1080i HP@L4) channels can be streamed with good quality.
This is the official technical specification about the mux:

I tried streaming with tsreader lite from the mux dump and that was right. VLC played this stream without problem.
I saw that tsreader creates the stream like a multiplex: it has pat, pmt and sdt:

VLC streams out only elementary streams.
Here is a sample dump from the whole multiplex A (230MB), this can be played locally without problem:

The dump made with this command:
Here is the corrupted output on streaming:
VLC streaming command:
- m1 m2 are HD channels.
- rtl, tv2, eunews, info are SD channels.
How can I stream with VLC valid streams? Is there a way to stream valid data with mux informations (pat, pmt, sdt) like tsreader does?
I tried to stream with ts{} parameters, like in this thread: viewtopic.php?f=2&t=58049, but without success. The output was corrupted. I think this is a bug. Developers: Please test it with the multiplex dump file and fix this issue
VLC version is 1.1.11 but the previous versions are behave like this one, too.
