Patch to fix chunk size (577 bytes, patch)
2006-04-02 11:00 UTC, Fabrizio Gennari 		committed Details | Review

Description Fabrizio Gennari 2006-04-02 11:00:07 UTC 
Please describe the problem:
In function gst_avi_demux_massage_index, if a very large chunk of data is found,
it is split in smaller chunks, and each chunk is indexed separately.

When splitting audio chunks, the block alignment is not taken in consideration,
so the smaller chunks could be of size which is not a multiple of the block
alignment.

This causes problems later, when passing the buffer to the next element,
negotiation could fail with a wrong size error.

Steps to reproduce:
1. 
2. 
3. 


Actual results:


Expected results:


Does this happen every time?

        Patch by: Fabrizio Gennari <fabrizio dot ge at tiscali dot it>

        * gst/avi/gstavidemux.c: (gst_avi_demux_parse_stream),
        (gst_avi_demux_parse_index), (gst_avi_demux_massage_index):
        When splitting audio chunks, the block alignment is not taken in
        consideration, so the smaller chunks could be of size which is
        not a multiple of the block alignment. Fixes #336904
