play ape audio files on vlc player has no sound and delay issues

[liugaohuan]

I am now using VLC media player 3.0.21 Vetinari (revision 3.0.21-0-gdd8bfdbabe8) to play ape audio files. in the playing process, if i do a pause action, vlc will be responding to my pause request after 5 seconds or so, which is not so instant. and when i do play action , what puzzles me is there is no sound any more in the playing process.

SO, is there any patch to fix the issue?

Sampling rate : 44.1 kHz
Bit depth : 16 bits
Encoding settings : Extra-high

I also have troubles with APE files on Windows. The higher encoding setting the more troubles.

With encoding setting High: the time counter is updating every 2 seconds and when clicking on the Pause button it takes between 1 and 2 seconds for the playback to be paused.

With encoding setting Extra High: the timeline is orange and bouncing from left to right end vice versa for about 5 seconds, the time counter is updating every 5 to 7 seconds, and when clicking on the Pause button it takes between 3 and 4 seconds for the playback to be paused.

With encoding setting Insane: the timeline is orange and bouncing from left to right end vice versa for about 25 seconds or no timeline at all, the time counter is updating every 25 seconds, and when clicking on the Pause button it takes between 15 and 20 seconds for the playback to be paused.

You should create a new report ticket on the VLC issues tracker with your above report, the link to your messages log, and the link to this thread:

If possible, because of this:

someone thought the term "pkt_dts_time="0.000000" is the cause of my problem. "pkt_dts_time=0.000000" will render playing not smoothly. and when you do a pause action, the next play will not work due to the pkt_dts_time`s value. Do you agree on this comment? But this audio file works fine with other audio player like Qmmp.

Now i am unable to create the bug tracker because i cannot login to https://code.videolan.org/videolan/vlc/-/issues. It says "Your account is pending approval from your GitLab administrator and hence blocked. Please contact your GitLab administrator if you think this is an error." I registered my gitLab account just now. It is maybe being reviewed?

From your previous replay, i thought this problem is kind of related the encoding setting?
