[Finished] MP1-4777 Additional info for video and audio (4 Viewers)

[yartat]

There was a discussion in another thread concerning the information returned by the existing support for recordings (TV and radio).

Should you present a small sample to check?

Could you present a small sample to check?

I think that recent series of "The Simpsons" have a multichannel soundtrack, and there is an episode starting in 10 minutes (at 18:00). I have scheduled it to record. It will start at 17:59 (I use one minute of pre-padding), but I will stop the recording at 18:05. As well as the pre-padding, the programme may start a minute or two late, but stopping it at 18:05 should ensure that part of the actual Simpsons episode is recorded. I don't know how big the TS file will be (it's HD!).

"Small" may be difficult.

I checked the info display on my Sony TV. Prior to the start of "The Simpsons", the audio type was displayed as English HE-AAC 2/0. This changed to English HE-AAC 3/2.1 after "The Simsons" had started. I stopped the recording even earlier than I said previously, but the TS file is still 121MB in size .

Where do we go from here?

It is a complicated to understand. In you case may be next things:

1. there are 3 different PATs with different audio PID on each PAT
   
2. there is 1 PAT and 3 different audio PID with offsets

so, I need a sample to understand what kind of solution should analyze.

1. there are 3 different PATs with different audio PID on each PAT
   
2. there is 1 PAT and 3 different audio PID with offsets

I don't know anything about how the data is stored in a TS file, so the following is just guesswork.

When TV Server is recording a channel, it simply writes to disk the data that it receives from the tuner. If the recording crosses the boundary between two programmes (as it does when pre-padding is used), TV Server does not know at the start of the recording what properties will change at the boundary between those programmes. So, the recording may start with audio=two-channel-sound, but later change to audio=five-channel-sound.

My guess is that every few seconds there is a header block in the data stream that defines the properties of the data that follows (until the next header block is encountered). So the audio will change at one of these header blocks.

So I think that the processing should probably be something like this:

(1) If the invoker of MediaInfo specifies offset=0, return the properties from the header block at the start of the file.

(2) If the invoker specifies (say) offset=5 minutes, find the first header block following the offset of 5 minutes from the start, and return the properties specified in that header block.

Perhaps @Owlsroost knows more about this?

@yartat
New MediaInfo put in DB VideoCodec like AVC High@L4.1 instead AVC

rowid    idFile    videoCodec    videoResolution    aspectRatio    hasSubtitles    audioCodec    audioChannels

Need or return old behavior (replace AVC High@L4.1 to AVC) or need add to all skin new video codec images like avc high@l4.1.png
