Anyone here uses Potplayer?

On my AMD laptop it plays tp files recorded from the Comet TV station with audio only and no video. The files play with both audio and video in VLC, MPV, and MPC-HT.

I can't figure out the problem. Thanks

Video codec not supported in Potplayer?

Thank you.

I don't know. TP files recorded from other stations play with sound and video.

Why does the muxing page show the original video and the encoded video? The original video is not needed.

Apparently, x264 software encoding retains the embedded CC in ts files while hardware encoding such as x264_amf removes it. This is ffmpeg, not just Clever. Can someone explain the inconsistency? Thanks.

I tried with ffmpeg and then Clever. Same result.

All source streams are always displayed in the multiplex window.
This guarantees maximum flexibility. Simply deselect or hide the streams you don't need.

That's interesting.
I just tested it with an h264 (avc) stream with cc.
Encoded with x264 and x264_qsv, both with modified resolution too.
The cc are still included in all outputs.

It's just amd amf then. I am not a fan of how AMD handles encoding. Intel QSV looks better.

Hello @ProWo

I'm trying to extract audio segments from an AAC file using Cut, but I can't get it to work. When importing the audio into Clever, the AAC file shows a duration of 1:02:23.706, but if I mux it into an MKA container, it shows 1:03:56.099.

If I try to extract a segment—especially near the end of the file—using the raw file (without a container), for example: 00:55:00.000 - 1:03:00.000, I get an error message: "Endtime Error! / Selected Endtime > Duration."

What I need is to cut certain audio segments that I don't need and then concatenate the rest, without transcoding and being as precise as possible.

How should this type of AAC format be edited?"

Raw .aac files do not store duration information, therefore the duration is estimated and is inaccurate.
To avoid this, mux the raw aac stream to mkv and cut this new mkv.
Then you can join/merge this mkv junks.
If you need aac as output, extract it from the final mkv.
