2.2.0 playing WMA tracks ~ 500 ms silence gap at start

Postby Puppy8 » 05 Mar 2015 10:58

When I start to play a WMA track or move to the next track in playlist, it plays first ~ 500 ms, then stops for another ~ 500 ms and continues to play the rest of track. Older 2.1.5 version did not have the issue.

I can't reproduce the issue, no problem here with v2.2.0 so far.

Please open Tools -> Messages (set Verbosity to 2) before you start the playback, and then paste the full resulting log here or on Pastebin.com if it's too long.

Also upload a short sample of a problematic file to either http://streams.videolan.org/upload/ or to Zippyshare.com (200 MB max) or to EmbedUpload.com, the latter will upload the file for you to several other hosts (use the default ones) and then post the link to the file here.

I made short 30 sec sample. It is sine wave created by Audacity and converted to WMA2 by Microsoft Expression Encoder 4. Notice the dropout at 0:01 position. The dropout also occurs in one second after seeking to a different position. There is no issue playing the sample file in VLC 2.1.5.

Sample file (518 KB): http://members.upc.cz/petr/temp/VLC220_ ... sample.wma

You should create a bugreport, mentioning it's a regression.
