* avformat/flacdec: Remove useless packetAndreas Rheinhardt2019-11-17
| | | | | | | | | | | flac_read_timestamp() applied av_init_packet() to a packet (which initializes all fields of the packet except for data and size) and then went on to use only the data and size fields. In other words: Said packet can be removed and replaced by an uint8_t * and an int.

* avformat/av1dec: Redo flushing of bsfAndreas Rheinhardt2019-11-14
| | | | | | | | | | | | | | The current approach has two different calls to av_bsf_send_packet(): A normal one, sending a packet; and an extraordinary one just for flushing. These can be unified into one by making use of the newly documented fact that av_bsf_send_packet() allows to signal flushing via empty packets (i.e. packets without data and side-data). This also fixes CID 1455685 which resulted from the fact that the call for flushing was not checked given that it couldn't fail.

* avformat/ftp: add AVOptions for authenticationNicolas Frattaroli2019-11-03
| | | | | | | | | | | | | | | | | This introduces two new AVOption options for the FTP protocol, one named ftp-user to supply the username to be used for auth, one named ftp-password to supply the password to be used for auth. These are useful for when an API user does not wish to deal with URL manipulation and percent encoding. Setting them while also having credentials in the URL will use the credentials from the URL. The rationale for this is that credentials embedded in the URL are probably more specific to what the user is trying to do than anything set by some API user.

* avformat/hls: Set AVFMT_TS_DISCONT flag on HLS input formatPhilip Langdale2019-10-30
| | | | | | | | | | | | | | | | | | | | | | | | | | There have been many reports over the years about problems when taking an HLS stream as input to `ffmpeg` where there are timestamp discontinuities present. This is explicitly supported in the HLS spec (EXT-X-DISCONTINUITY) and often used for ad injection. Various fixes and work-arounds have been proposed over the years, but one step that seems obvious, even if it's not a complete fix, is to mark the HLS input format as supporting discontinuities. This will prevent timestamp fixup logic in ffmpeg.c kicking in that ends up mangling the timestamps unnecessarily. I've tested this out with an example provided by Joe Koberg early last year, and it is sufficient to allow `ffmpeg` to download and mux the stream correctly. Joe had briefly suggested that other situations can still be handled incorrectly, but this seems like a strict improvement.
