Bernhard and Chen,
Here is what I did, for example,
I have 3 separate video and audio files.
Video 1.MPG Audio 1.WAV
Video 2.MPG Audio 2.WAV
Video 3.MPG Audio 3.WAV
Each MPEG 2 file has added sequence headers in
front of each GOP for record to DVD. Each Audio file
was compressed from WAV data with identical header
files. I can NOT concatenate the video or audio files
before multiplex with timing and limited space. So, I
have to do
Mp2enc < Audio1.WAV -o Audio1.MP2
Mp2enc < Audio2.WAV -o Audio2.MP2
Mp2enc < Audio3.WAV -o Audio3.MP2
Mplex -f 9 Video1.MPG Audio1.MP2 -o TempMplex.MPG
Cat TempMplex.MPG >> Mplex.MPG
Mplex -f 9 Video2.MPG Audio2.MP2 -o TempMplex.MPG
Cat TempMplex.MPG >> Mplex.MPG
Mplex -f 9 Video3.MPG Audio3.MP2 -o TempMplex.MPG
Cat TempMplex.MPG >> Mplex.MPG
The result Mplex.MPG can NOT be recorded to DVD.
I looked at the video files using MPEG inspector,
Video*.MPG are the right format with 15 frames / GOP.
Is there any time stamp issue or something? Can
anyone let me know what is the "single pass" is about,
sorry, I'm new to this.
thanks, Cindy
