extracts from youtube show wrong duration info

Recommended Posts

.m4a - sound files are shown with wrong duration. A file is shown with duration 19:25, immediately after start of playing it the current time jumps to 9:43 and progress is shown as 50%, updated smoothly from there.
The stock player on the other hand displays the duration as 09:42, starting at 00:00.
This behaviour has been seen with all files which were created by youtube-dl on linux
The origin from youtube-videos may be significant.
I have some .mp3 files created by youtube-mp3 online converter (http://www.youtube-mp3.org/)
that show another type of duration misinformation, here an example file is shown as 18:13 but runs for 4:30 (there is some whitespace at the end of it). Factor 4 this time and here the progress bar starts at 00:00 and it skipps to the next song at 25%.
However, the latter error is only with some .mp3 created that way while others behave as expected.

I've got some m4a podcast files which do play, but won't allow ffwd or scrubbing or remembering playback position, so I suspect your issue is probably similar to my files. Email a sample to poweramp.maxmpz(at)gmail.com.

I can confirm this problem.


Downloaded a ripped .m4a from YouTube using FlashGot v1.5.6.12 on Firefox v38.0.5.


Currently using Poweramp v2.0.10-build-580-play (Full Version).


Poweramp thinks the song duration is twice as long. The song starts from the beginning but Poweramp sets the scrubber at 50% and the time is set to the actual length of the song.


Example: If the song duration is 3:12, Poweramp will set the song duration at 6:24 and set the scrubber to 3:12. It will then continue to play until 6:24.


Here's some more info:

  • Poweramp: 2.0.10-build-580-play (Full Version)
  • Phone: Samsung Galaxy S4 1337M
  • Android: 4.4.2
