Hi Cypheros,

Here I have another umax ts file relayed by another provider and it seems it has similar time stamp error like previous one.

link

Can you check if the typical fix via TSD would do?

Thanks.

TS-Doctor 1.2 / Clean source and Audio error
« am: Oktober 06, 2015, 06:51:32 »
Hi Cypheros,

Thank you for the update 174 and I use it very well. (Will soon buy the license)

But I still have some audio sync issue and want to know if the audio error like AC3 crc error from every clean source at the attached log is unavoidable due to PCR issue at my source UMAX?

I don't have any video error but get always audio error regularly in every clean source. This is for sure nothing to do with audio sync issue I've got?

Thanks,
freebits

The delay between audio and video you can find in the log is no error, that's OK for transport streams. It will be automatically corrected during playback.

I checked your samples and audio video sync is OK. Please be aware that playback of UHD will bring your computer to the limits. If CPU usage is at maximum, the system is not able to keep audio and video in perfect sync.
Try to playback with a H.265 capable hardware decoder like Samsung UHD TV and you'll see that audio and video is in sync.

I test those clips via 4K UHD media player supporting hw acceleration of HEVC stream and saw the audio sync issue from it. Anyway, will test it again after remuxing it with some delay using ffmpeg or so..

Okay. Then can I adjust the audio delay from the fixed recording?

Cypheros,

Another observation is I don't get message like 'PCR error is detected and you can "Virtually cut and reopen' in a larger recordings.

The only files that I got such message was rather smaller recordings like 1gb or so.

When I get the message?

The fix doesn't change the synch because all timers (audio, video, subtitles, etc. ) are changed with the same value. Most sync problems are caused by errors during remuxing to other container formats like MKV, MP4, ...
If you have a transport stream with lost packets due to reception problems, remuxers tend to ignore missing audio parts and you'll get an audio stream that is shorter that the video stream. That causes the sync problems. As you stay with transport stream format, any part of the stream has it's own timers to keep audio and video in sync, even if some audio or video packets get lost during transmission.

Thank you.

I meant the fixed TS stream not the remuxed mkv or mp4.
I thought the attached log is from the relative very clean TS recording and I saw audio is slight ahead of video during the whole play.

Can the delay below found in the log affect the audio/video sync?

Video PCR to PTS difference -912 ms
$01A1: Delay to video stream = -494ms

Can I add audio delay in millisecond when cutting/fixing the file to have better sync?

Thank you.

Understood your point.

Btw, I see some recordings fixed by TS-Doctor have slight audio sync issue (Audio is slightly faster than video) and some are good in sync.

This fix does not touch anything regarding to Audio sync stuff and is it purely because of recording error or signal strength when audio is out of sync?

Thank you so much, Cypheros. It's been working great for several large recording files.

But I have additional questions about TS-Doctor before buying it.

1. Can I skip audio detail scan? It takes very long time to scan PCR switching position and audio scan adds additional time to get the final fix if the recording is very long? It would be best if another option to on/off the audio detail scan is added so I can save some time fixing the recordings.

2. Auto cut does not work? We have some midprogram advertisings in the UHD channel but TS-Doctor doesn't ask if I'd like to cut them automatically or not. I think the problematic TS sample I shared had also the commercial for your test.

Thanks!

I guess it should be possible to fix the PCR problems.

Great. Will it take some more time?

Great, download is in progress. I'll check it ASAP.

Thank you. Do you think if it's possible to fix?

Thanks for the quick reply :)

Here's the link of the cut file as you instructed.

Thank you for the reply.

But unfortunately, the main recording (22gb) was not fixed via two time fix. The duration and bitrate info was not correct after 2nd fix and the TS-Doctor didn't ask for the fix of invalid PCR info at 2nd fix different from the sample. The previous sample was cut via Raw cutter in TS-Doctor btw.

Pls check the attached logs of main recording. Dunno if you need larger samples to investigate this.

Thanks.
