* avformat/mux: return a pointer to the packet in ff_interleaved_peek()James Almer2021-02-13
| | | | | | | And make it const, so the caller doesn't attempt to change it. ff_get_muxer_ts_offset() should be used to get the muxer timestamp offset. Signed-off-by: James Almer <jamrial@gmail.com>

* avformat/movenc: remove unnecessary HDR metadata log messagesJan Ekström2021-02-10
| | | | | | | | | | | | | | These made sense before 3ebf449766d4b69a7774c4990fb24fe71c848a3e when the creation of these boxes was specifically requested by the user, but now they have become unnecessary as they are just like many other boxes: If the input has the information required, they are written, otherwise they are not. They were moved to verbose verbosity level (which happens to be the last level still relatively usable), and now appear either once (normal MP4 muxing), or thrice (with the faststart flag set) in any normal MP4 usage, without giving much useful information. Thus, remove them in their current form.

* avformat/libsrt: fix race condition with libsrt_network_wait_fd and epollMarton Balint2021-02-07
| | | | | | | | | | | | | | | The way SRT's async / epoll-based IO works is that the event status is stored in the epoll containers. That is, if an event occurs on an SRT socket, and that SRT socket isn't part of any epoll container, then that event is lost. If we later add that socket to an epoll container, we still won't receive the event even if it wasn't serviced. Therefore we create the epoll and put the fd into it right after the connection is established.

* avformat/rtsp: Fix build failure when RTP demuxers are disabledAndreas Rheinhardt2021-02-03
| | | | | | | | | | | | | | | rtsp.c uses a check of the form "if (CONFIG_RTSP_DEMUXER && ...) {}" with the intent to make the code compilable even though the part guarded by this check contains calls to functions that don't exist when the RTSP demuxer is disabled. Yet even then compilers still need a declaration of all the functions in the dead code block and error out if not (due to our usage of -Werror=implicit-function-declaration) and no such declaration exists for a static function in rtsp.c. Simply adding a declaration leads to a "used but never defined" warning, therefore this commit resorts to an #if.
