Description Florent Thiéry 2008-11-05 17:15:30 UTC
Please describe the problem:
All ffmpeg-based media players/frameworks complain every second (approx) when playing the following video back (see below).

The effects are mostly side effects. When h264 parse is inserted, warnings resolve but video plays back badly

Steps to reproduce:
1. wget https://flowty-public-dev.s3.amazonaws.com/2008-10-22_20-42-59.mp4
2. GST_DEBUG=2 gst-launch-0.10 -vvv filesrc location=emc.mp4 ! qtdemux ! ffdec_h264 ! xvimagesink


Actual results:
Errors, sometimes non-fluid playback (whenever a decoding error happens, tiny freeze)

Expected results:
Fluid playback and no decoding errors

Does this happen every time?
Yes

Comment 1 Wim Taymans 2008-11-10 10:47:09 UTC
The decoding error is when the decoder gets the config string, which does not decode to anything. It does however not seem to cause any problems or hickups in the playback for me.
Comment 2 Edward Hervey 2009-03-05 06:54:14 UTC
Same thing here, But the video plays fine. Maybe those errors were fatal previously, but they're now just informational.

Closing bug.
