ffplay: Broken playback of H.264 RTSP streams

[Johannes]

The playback of H.264 RTSP streams seems to be broken. Only the upper part of a frame is displayed and the lower part gets interpolated from the last row of correct pixels. Additionally, some pixels in the left upper corner are corrupted. This might be some buffer problem?

This is also similar to ticket #285, but which is fixed according to the latest post.

The following error messages are produced, when connecting to this stream: rtsp://dmzosx001.dpa.act.gov.au/medium

The streams works nicely with VLC, though i don't think, that the stream is corrupt.

The stream is not very exciting atm, but works fine for me.

[Carl Eugen Hoyos]

The stream still plays fine for me.
