Before the introduction of AV_CODEC_ID_TIMED_ID3 for timed_id3 metadata streams
in mpegts (commit 4a4437c0fb), AV_CODEC_ID_SMPTE_KLV
was the only existing codec for metadata.
It seems that this codec has a 5-bytes metadata header[1] that, for some reason,
was always skipped when decoding data packets.
However, when working with a AV_CODEC_ID_TIMED_ID3 streams, this results in the
5 first bytes of the payload being cut-off, which includes essential informations
such as the ID3 tag version.
This patch fixes the issue by keeping the 5-bytes skip only for AV_CODEC_ID_SMPTE_KLV
streams.
