tsMuxeR - How to join two streams with different audio delay each?

[jgae]

tsMuxeR 2.6.12, Win7 64bit

I want to join two .ts transport streams, one has an audio delay of 10ms, the other one has -800ms. I received them from satellite disrupted by an advertisment break. I do not know why these delays are such different.

If I try to merge both streams together by tsMuxeR's join function everything seems to work well. But it takes for all the streams to join always the delay configuration derived from the first stream and applies it to all the following parts. That results in an asynchronous output between lips view and voice.

Does any one know how to workaround this?

Thanks

You could "fix" the audio track of each before appending by deleting or adding silence (padding) , so that the effective delay is 0ms

Yeah, that was the solution! Thanks.

Ok, I've demuxed the ts stream in separate video and audio tracks now. Either the first ms of audio or the first ms of video can be cut off with tsMuxeR's "Split&Cut" feature to produce a new copy of track. Then mux both tracks back together. Result is a new ts stream with delay 0 and correct synchronous audio.

It's tricky and a lot of work. But it flies.

It's tsMuxeR better that Audacity or AudioCoder when we "work" with mp4's ?

In my case above there is nothing to re-code. It's only the need for shift of relative position between audio and video track. And cut of some miliseconds at the beginning of a track is somewhat faster done with tsMuxeR. tsMuxeR does not re-code the track. It's only a copy. In my case audio was AC3 coded, in your's it's maybe AAC. Demux the stream into it's parts is necessary anyway.

I had try to author an mp4 [AAC]; but is seams to me that it is a lot more easy to author (audio or video or both at once) after is "transfer" into a .vob [AC3], since I am keeping upgrading to file all the way to an ISO to be save it into the HDD (or else) or burn into a DVD.

- I "recode" with AVStoDVD
- I just want to adjust the volume on the fly & re-check all the files, since some originals mp4 (few) come out very loud & others with low volume.
