| | | | | | | | It was introduced in d3d9b1fc8e2dfc8b4d66c9916ab7221062ff4660; Fixes Coverity issue #733800. Reviewed-by: Tomas Härdin <tjoppen@acc.umu.se> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
* avformat/mxfdec: Don't use wrong type of pointerAndreas Rheinhardt2021-03-19
| | | | | | | | | | | If one of the two results of a ternary conditional is a pointer to void, the type of the whole conditional operator is a pointer to void, even when the other possible result is not a pointer to void. This loophole in the type system has allowed mxf_read_local_tags to have a pointer of type pointer to MXFMetadataSet that actually points to an MXFContext.

* avformat/mxfdec: Fix memleak upon repeating tagsAndreas Rheinhardt2020-07-24
| | | | | | | | | | | When parsing MXF encountering some tags leads to allocations. And when these tags were encountered repeatedly, this could lead to memleaks, because the pointer to the old data got simply overwritten with a pointer to the new data (or to NULL on allocation failure). This has been fixed. Reviewed-by: Tomas Härdin <tjoppen@acc.umu.se> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
* avformat/mxfdec: Fix memleak when parsing tag failsAndreas Rheinhardt2020-07-24
| | | | | | | | | | | | | | The MXF demuxer uses an array of pointers to different structures of metadata (all containing a common initial sequence containing a type field to distinguish them) and some of these structures contain pointers to separately allocated subelements. If an error happens while reading and creating the tags, the semi-finished new tag is freed using the function to free these tags. But this function doesn't free the already allocated subelements, because the type has not been set yet. This commit changes this.
