Description
The wav format decoder has a hard-coded assumption that there is 1 audio stream at index 0 and optionally one video stream at index 1.
When wav_read_header encounters an ID3 tag, it will call ff_id3v2_parse_apic which creates a new stream for the attached picture.
If the ID3 tag comes before the fmt tag, the audio tag will therefore end up at index 1 instead of index 0.
wav_read_packet on the other hand will mark all packets as belonging to index 0, thus you may end up never finding a packet to feed to the audio codec.
The easiest fix is probably to re-order the streams in read_header to ensure the assumptions hold up.
