| | | | | | | | | | | | | frame->enc_ctrl.Payload is malloced in get_free_frame, directly memset the whole structure of enc_ctrl to zero will cause the memory leak for enc_ctrl.Payload. frame->enc_ctrl as a structure will be malloc and init to zero by calling frame = av_mallocz(sizeof(*frame)), so the memset is redundant and can be removed.

* Revert "lavf/utils: Allow url credentials to contain a slash."Marton Balint2019-05-18
| | | | | | | | | | | | | | | | This reverts commit dd06f022b07438d650c82255dff16908ba04244a. Fixes ticket #7871 and reopens ticket #7816. The introduced regression caused URL's with @ in them to be parsed incorrectly which is a bigger issue then not being able to specify the slash character as a password. I think there are better ways to fix the original issue, like being able to specify HTTP username and password as a protocol option, or adding a protocol option to percent-decode the URL first.
