typefinding: mp3 file is misdetected as H.263
Last modified: 2014-04-12 13:24:23 UTC
when I execute "gst-launch playbin uri=file:///filename.mp3",
file is recognized as h.263 but it contains only audio stream.
gst/typefind/gsttypefindfunction.c h263_video_type_find function results good(1), bad(0) so this problem is occured.
I will attach the mp3 file.
Thanks for the bug report and the sample file.
This should fix it:

typefindfunctions: lower H.263 typefinder max probability
The typefinder returns LIKELY for as little as one possible
sync and no bad sync (not even taking into account how much
data was looked at for that). It's generally just not fit
for purpose, so should just not return anything like LIKELY
at all ever, even more so since it only recognises one out
of ten H263 files, and likes to mis-detect mp3s as H263.
