Describe the bug

Hi, I'm experiencing and audio/video desync with almost all my videos. All my library is encoded with the following ffmpeg command: ffmpeg -progress pipe:1 -i {INPUTFILE} -map 0:v:0 -c:v hevc_nvenc -cq:v 19 -preset slow -map 0:a -c:a eac3 -b:a 512K

Hi guys, I can understand that this is an open source project with a lot of thinks to do, but your application, despite being focused to media content, does not have a player 100% working. I opened this issue and this: #3025, neither of them with a single comment.

Can I ask if you have a workaround to have the audio 100% working? I'm tired of hoping that the next update will fix it

Could you describe in more detail how to reproduce this? Such as:

One thing to note is that AFAIU the playback code is undergoing a major rewrite, which may inadvertently fix this issue (and perhaps your other issue) when it lands; this would mean that less attention is currently on tricky or hard to reproduce playback issues.

Hi:

How long does it take for noticeable audio desync to occur?

30 to 60 seconds. The delay between audio/video keep increasing

Can you try reproducing with videos encoded with libx265 or x264 instead of hevc_nvenc, or stereo instead of eac3?

I will try to generate a couple of clips with different codec audio/video.

Could you provide a sample file that reproduces this behaviour?

Same of above, I will try to generate a couple of minutes video just for this test.

Sweet. Should we wait for this instead try to solve this issue? There is an expected release date or a blog topic/issues/other which can I follow?
