Parsers? What do you mean?

I use  av_read_frame() and then either avcodec_decode_audio4() or  avcodec_decode_video2().

Is there any additional parsing possible to do? (I went through the ffplay source but I didn't notice anything different there.)

Right after calling avformat_open_input() on the AvFormatContext I run av_find_stream_info(), which has the effect that mp2 is correctly recognized as mp2 instead of mp3, however it has no influence on the errors.
