.ts video file problematic for transcoding

[marcorocchini]

Hi,

a cat here. However


Please can you download this .ts video?

https://www.swisstransfer.com/d/3a601a60-de2d-4c74-bf07-f1198f53fe7c

I can play it on VLC, for a duration of 34 minutes and 31 seconds.

But I cannot transcode it, using avisynth/ffmpeg or other editing programs. Seems that a part of it is "invisibile":
the part start at 4'42'' and finish at 26'20''

Is there a way to resolve? thanks

The file has a corruption on the PRC and has errors in the audio/video streams.



You can use TSDoctor to fix it.

If you can play it in VLC - VLC can convert video too


There are 2 video streams, 3 audio streams. You can demux or combine them with eac3to, it will also fix the gaps and errors

1: h264/AVC, 1080i50 (16:9)
2: h264/AVC, 720p50 (16:9), 152987ms
3: MP2, Italian, 2.0 channels, 128kbps, 48kHz, -1153ms
4: MP2, Italian, 2.0 channels, 128kbps, 48kHz, 152523ms
5: MP2, oth, 1.0 channels, 64kbps, 48kHz, -1177ms


Stream 1 video is 10:47, Stream 2 video is 23:42 . It looks like they play sequentially in VLC. Stream 4 audio has long audio silence and 26:15. Stream 5 is 34:40 but lower bitrate audio .You could demux them and edit them as you see fit. The different resolution would cause problem for many programs, so you should probably match them

eac3to "Rai 3 TGR Emilia-Romagn.ts" -demux

Will only demux the 1st video , you can specify stream 2 separately

eg.

eac3to "Rai 3 TGR Emilia-Romagn.ts" -demux 2: stream2.h264

For the "hidden" Stream 2 , Stream 4 belong together with Stream 2, the delay is about -153s . I wouldn't re-encode the audio, I'd just cut the beginning silence and mux it (no quality loss)

You can test sync, seeking in MPCHC to preview, to see how much you need to cut

Stream2

vid2 = DGSource("stream2.dgi")

aud2 = FFaudioSource("Rai 3 TGR Emilia-Romagn - 4 - MP2, Italian, 2.0 channels, 128kbps, 48kHz.mp2")

audiodub(vid2,aud2)

delayaudio(-153)

Or if you wanted to combine/join/edit with Video Stream 1 (and audio stream 3, they belong together), you can do that in the script too .

(Personally, I prefer not to re-encode audio, but mp2 audio might not be compatible for your situation)
