Allows the MPC to play data transmission in the vob file.

The latest version of storm audio and video is used in the following discussions. 5.03.24

Is there anything else that cannot be played in the well-known Media Player classic? Yes, I have encountered this situation.

I have a test album with three audio tracks, 6-channel AC3 (0x80), 5-channel DTS (0x89 ), 2-channel AC3 (0x82) is the companion song. When playing the video in a DVD drive, everything works normally, and all three audio tracks can be played. However, after using vstrip to extract the vob file, except for 6-channel AC3 audio tracks, the MPC can no longer play the other two audio tracks (specifically, it cannot be selected). If the Three audio tracks are extracted separately, only the AC3 audio tracks can be played, and DTS cannot play any sound.

After a long time, I almost gave up. I thought that the playing of DTs audio tracks was not supported by the PC. The result of Google was that only windvd and powerdvd could be decompressed to play DTs, the latest versions of the two software can be played, but both are commercial software and cannot be provided. Source code And if you can't play any of them, what else do you want to do. So I think:

1. the playing of data transmission is not supported for the time being (the reason is that I have Code Found a dtsdec-0.0.1 folder, it seems that the DTs decoding function is not completed );

2. currently, there is no filter to support DTS decoding (but I still have doubts on this point, because the DTs decoding filter is obviously available in ffdshow, but the actual situation cannot be heard, so I only have doubts)


So I went to research vstrip to extract the DVD file.

Another powerful free audio and video playing software, was originally found to boast that KMP is powerful, and I did not agree with it, but I downloaded one with a look at it, I didn't expect that KMP could play the DTs audio that gave me a headache. It was a bit unacceptable for me for a while. I thought that the MPC was a matter of course No. 1. Now I didn't expect that South Korea had such a good software, in addition, it surpassed the MPC (later I realized that KMP did not actually surpass the MPC in terms of functionality. This is what we will talk about later ). However, I am relieved to see that there are many developers in KMP. Maybe some of them specialize in DTS decoding. After all, gabest is just a person. However, KMP is not open-source, so I have no choice but to study it. I am depressed for two days.

However, after carefully studying the functions of KMP, I finally discovered the secret of KMP playing DTS. In fact, it is not mysterious. KMP also uses a plug-in filter to play the DTs in the vob file, this splitter filter was developed by gabest and is named mpegsplitter. ax.

I searched the installation directory of storm audio and video, and even the entire drive C did not find the existence of this file. When I added this filter to the filter management of the MPC, my DTS audio track was recognized immediately and I heard the dream sound from the PC. Is to compare the effect before and after loading the filter:
