Description
I am trying to transcode from WMA Lossless to anything else, but this bug report desribes transcoding to MP3 problems. Transcoding to OGG/Flac results in the same anyway.
Playing file anywhere, be it VLC, Qmmp, Clementine, ffplay, there is a loud static noise at the end of the file. The static is also present when I play the original wma file in ffplay. File itself is not broken, because WMP 11/Win7 plays them w/o much hassle.
CLI action used for transcoding:
ffmpeg -report -v 9 -loglevel 99 -i 25_Sciezka_25.wma 25_Sciezka_25.mp3
As an attachment I am sending both the original file and the transcoded one, plus logfile of the conversion process.

First attachment is invalid, as that is logfile from conversion of the file, that was to large to upload it here, and it could not be truncated due to the nature of the problem.
comment:2 Changed 15 months ago by cehoyos
- Keywords wma convert noise removed
- Status changed from new to open
- Version changed from unspecified to git-master
- Component changed from FFmpeg to avcodec
- Reproduced by developer set
For future bug reports: Please do not use other software (in your case libmp3lame) to test ffmpeg if this is not necessary; for audio decoding reports, I believe decoding to wav is preferred.
Attaching the output file is usually not necessary.
out.wav has the described severe audible artefacts after 30 seconds.
$ ffmpeg -i 03_Track_3.wma out.wav
