Converting MPEG-TS to MPEG-PS (please help! bug in mpegpsmux?)

[Bernhard Graaf]

Hi,

 

is there anyone who can tell me, why the mpepsmux-element recognized only
the video caps?

 

If I try to use the pipe only with audio-pids, I'll get a file with
audio-data, but the Message is also:

/GstPipeline:pipeline0/MpegPsMux:mpegpsmux0.GstPad:pad0: caps = video/mpeg,
mpegversion=(int)2, systemstream=(boolean)false

 

So, there must be a bug in the mpegpsmux-element!

 

Who can help me?

Bernhard

Hi,

 

Sorry, there is a fault in my pipe. I try this:

gst-launch-0.10 -v dvbsrc adapter=0 frequency=12544000 pids=97:511:512:515
polarity='h' symbol-rate=22000 ! mpegtsdemux es-pids=511:512 ! mpegpsmux !
filesink location=test.mpg

 

The Messages are:

 

New clock: MpegTSClock

/GstPipeline:pipeline0/GstMpegTSDemux:mpegtsdemux0.GstPad:sink: caps =
video/mpegts, mpegversion=(int)2, systemstream=(boolean)true

/GstPipeline:pipeline0/GstMpegTSDemux:mpegtsdemux0: pat-info =
((GValueArray*) 0x8307b60)

/GstPipeline:pipeline0/GstMpegTSDemux:mpegtsdemux0: pmt-info =
((MpegTsPmtInfo*) 0xb6c04680)

/GstPipeline:pipeline0/MpegPsMux:mpegpsmux0.GstPad:pad0: caps = video/mpeg,
mpegversion=(int)2, systemstream=(boolean)false

/GstPipeline:pipeline0/MpegPsMux:mpegpsmux0.GstPad:src: caps = video/mpeg,
mpegversion=(int)2, systemstream=(boolean)true

/GstPipeline:pipeline0/GstFileSink:filesink0.GstPad:sink: caps = video/mpeg,
mpegversion=(int)2, systemstream=(boolean)true

 

And that's what I get: Only the video-stream without any audio.

 

What's wrong with this pipe?

 

Thanks' a lot!

Bernhard

Hi,

 

I have a problem for seeking in MPEG-TS-files (to slow) and want to convert
a TS-Stream to PS.

But it seems to be a little tricky to select the pids. My pipe looks like
this:

'gst-launch-0.10 dvbsrc pids=97:511:512 frequ... ! mpegtsdemux
es-pids=511:512 !  mpeg2dec ! filesink location=test.mpg'

 

The pids are: 97 = PMT, 511 = Video, 512 = Audio.

 

But it doesn't work. The file is always 0 Bytes long.

 

Without converting, it's a very simple pipe:

'gst-launch-0.10 dvbsrc pids=97:511:512 frequ... ! filesink
location=test.mpg'

 

And it's works very good.

 

What to I wrong to convert the stream?

 

Thanks' a lot for helping!!

Bernhard
