A new build of MC30 which plays WTV files is here: https://yabb.jriver.com/interact/index.php/topic,135519.msg938823.html#msg938823

Plays - or plays and records?

Yaobing · « **Reply #52 on:** March 27, 2023, 03:56:19 pm »

Just plays.

mcq · « **Reply #53 on:** March 27, 2023, 03:58:31 pm »

But the current one plays - or is it the change you did for me to get the video to show?

JimH · « **Reply #54 on:** March 27, 2023, 03:59:19 pm »

I believe that you have a special version.

mcq · « **Reply #55 on:** March 27, 2023, 04:00:48 pm »

Ok - so it's that one on wider release - thanks

Yaobing · « **Reply #56 on:** March 27, 2023, 05:09:42 pm »

You had build 85. The release now is 87. It has a few more fixes, one of which is related to WTV playback, on audio.

mcq · « **Reply #57 on:** March 27, 2023, 05:13:15 pm »

Excellent - thanks for that Yaobing - will move to 87
Does that mean that I still need to make any change to filetype wtv from automatic to 'experimental' - or is that what you have fixed?

Yaobing · « **Reply #58 on:** March 27, 2023, 05:36:55 pm »

I think automatic should work now. Try it.

mcq · « **Reply #59 on:** March 27, 2023, 06:09:58 pm »

Will do tomorrow - if I remember right this was to endure that AAC 5.1 came out as such not stereo

Yaobing · « **Reply #60 on:** March 27, 2023, 06:40:22 pm »

Exactly.

Exactly.

With multiple audio tracks the new version seems to pick the default track from WTV files - Stereo, when I want AC3 - without an option to switch (or at least I haven’t found it yet)

mcq · « **Reply #62 on:** March 28, 2023, 06:16:48 am »

Agree with sheppy99 when tracks are as per attached JR picks MPEG stereo, WMC picks AC3 5.1
The sample i sent you Yaobing had the tracks in the opposite order - i.e. AC3 was Stream 1 with MPEG Stream 2
Will look later at AAC as I need a file with stereo and 5.1 on it - the AAC sample I sent you Yaobing was 5.1 on both tracks!
There's no knowing what the broadcaster will do in this regard.

Yaobing · « **Reply #63 on:** March 28, 2023, 08:32:26 am »

I will investigate this one.

I think I got this one. Just need you to confirm:

The sample recording of the football game has only one audio stream (AAC stereo).

The AC3 BBC Test card has two audio streams: AC3 5.1 English, and NAR [nar] (mp2) [visual impaired]

The AAC BBC Test card has two audio streams: AAC 5.1 English, and AAC mono English.

Yaobing · « **Reply #65 on:** March 29, 2023, 09:48:20 am »

I think we got it right. I tried playing those sample videos in VLC. The same audio streams are detected there too.

mcq · « **Reply #66 on:** March 29, 2023, 11:55:01 am »

As far as I can see both my clips have the true 5.1 as Stream 1

The AC3 clip - Stream 2 is marked MPEG - but I don't hear any audio when switched to it in VLC
The AAC clip - Stream 2 is marked as 5.1 - but again - I don't hear any audio when switched to in VLC

So for both clips JR is playing Stream 1

The question is if sheppy99's clip has Stereo on Track 1 and 5.1 on Track 2 - how does he select which track to hear - don't think JR has a 'track' choice like VLC - probably needs a sample from sheppy99 to resolve.

Correct.

The AC3 clip - Stream 2 is marked MPEG - but I don't hear any audio when switched to it in VLC

In my tests, VLC does play with sound, using stream 2, but since it is stereo only, it plays the L and R channels with sound, all other channels are silent. Now (after my fix today) MC does the same.

With stream 2, it is total silence, in VLC and in MC (with my fix today). So the clip probably does not really have audio in the second stream, although it says it has a second stream.

Yes. In a few days when you get a new build with my fix today, you will be able to switch to other available streams.

I fixed that. Wait for a new build to come out in a few days.

Thanks for confirming that there are two advertised audio streams in your test file, which I also confirmed with VLC.

Brilliant, will try that later. Thanks for the prompt response

mcq · « **Reply #71 on:** March 29, 2023, 05:39:51 pm »

Hi sheppy99 - out of interest - when you open your file in VLC is the 5.1 channel the first or second audio stream?

A quick look at 5 of the latest WTV files suggests AC3 is usually the last of the sound streams

mcq · « **Reply #74 on:** March 30, 2023, 04:20:54 am »

What is your broadcast source - is it in UK, in EU?
I tried to find some regulation or standard on this, but no luck so far.

mcq · « **Reply #75 on:** March 30, 2023, 04:44:38 am »

I won't be continuing to persevere with JR if there isn't a commitment to provide wtv recording.
Mixed WMC/MC working would need to coexist for some time.

JimH · « **Reply #76 on:** May 06, 2023, 12:15:20 pm »

31.0.8 is available now: https://yabb.jriver.com/interact/index.php/topic,135878.msg941279.html#msg941279

It has some tag changes.
