Hi,
I have try to understand how work remux.c with the steam and when I add
in remux.c after
for (int i = PayloadOffset; scanning && i < TS_SIZE; i++) {
scanner <<= 8;
scanner |= Data[i];
line 770 : dbgframes("type = %02X, scanner = %10X \n", type, scanner);
I have this output :
type = 02, scanner = 0
type = 02, scanner = 0
type = 02, scanner = 0
type = 02, scanner = 1
type = 02, scanner = 109
type = 02, scanner = 10950
type = 02, scanner = 1095000
type = 02, scanner = 9500000
type = 02, scanner = 50000000
type = 02, scanner = 1
type = 02, scanner = 106
type = 02, scanner = 10600

Never stream with type 0x1B
When I play stream with mplayer as : mplayer rtp://@232.0.1.17:8200 I
have this output
TS file format detected.
Stream not seekable!
VIDEO H264(pid=1217) AUDIO MPA(pid=1317) NO SUBS (yet)! PROGRAM N. 1017
Stream not seekable!

Trying to force audio codec driver family libmad...
Opening audio decoder: [libmad] libmad mpeg audio decoder
AUDIO: 48000 Hz, 2 ch, s16le, 128.0 kbit/8.33% (ratio: 16000->192000)
Selected audio codec: [mad] afm: libmad (libMAD MPEG layer 1-2-3)
==========================================================================
Is this is the mpeg2 streams with H264 codec ?
How to identify this stream ?
Thanks for you help.
