The tag library supports WMA, so add the mimetype. Some wma files have embedded album art encoded as a video stream alongside the audio: ``` Input #0, asf, from '01. Emergency Pulloff.wma': Metadata: (snip) Duration: 00:03:11.47, start: 0.000000, bitrate: 129 kb/s Stream #0:0: Video: mjpeg, yuvj420p(pc, bt470bg/unknown/unknown), 200x200 [SAR 96:96 DAR 1:1], 90k tbr, 90k tbn, 90k tbc Metadata: comment : Cover (front) Stream #0:1: Audio: wmav2 (a[1][0][0] / 0x0161), 44100 Hz, stereo, fltp, 128 kb/s Output #0, opus, to '/tmp/output.opus': Output file #0 does not contain any stream ``` The `-map 0:0` passed to ffmpeg is selecting the video stream to transcode, then `-vn` says not to transcode video, so the whole process returns an error code: ``` 2021/05/28 18:59:09 transcoding according to transcoding profile of 96k 2021/05/28 18:59:09 serving transcode `02. Cotton Patch Rag.wma`: cache [opus/96k] miss! 2021/05/28 18:59:09 serving transcode `02. Cotton Patch Rag.wma`: error: starting transcode: running ffmpeg: exit status 1 ``` I believe the correct solution here is to use an _audio_ stream specifier, as in `-map 0🅰️0`. Doing this selects the audio and successfully performs the transcode.
