2017-02-13AVFrame: add an opaque_ref fieldwm4
This is an extended version of the AVFrame.opaque field, which can be used to attach arbitrary user information to an AVFrame. The usefulness of the opaque field is rather limited, because it can store only up to 32 bits of information (or 64 bit on 64 bit systems). It's not possible to set this field to a memory allocation, because there is no way to deallocate it correctly. The opaque_ref field circumvents this by letting the user set an AVBuffer, which makes the user data refcounted. Signed-off-by: Anton Khirnov <anton@khirnov.net> Merges Libav commit 04f3bd349651.

2017-02-07avformat/hlsenc: add hls_flag option to write segments to temporary file ↵Aman Gupta
until complete Adds a `-hls_flags +temp_file` which will write segment data to filename.tmp, and then rename to filename when the segment is complete. This patch is similar in spirit to one used in Plex's ffmpeg fork, and allows a transcoding webserver to ensure incomplete segment files are never served up accidentally.

Return a channel layout and the number of channels based on the specified name. This function is similar to av_get_channel_layout(), but can also parse unknown channel layout specifications. Unknown channel layout specifications are a decimal number and a capital 'C' suffix, in order to not break compatibility with the lowercase 'c' suffix, which is used for a guessed channel layout with the specified number of channels.

2017-01-12avformat/hlsenc: hls_start_number_source and start_numberBodecs Bela
start_number option starts the playlist sequence number (#EXT-X-MEDIA-SEQUENCE) from the specified number. Unless hls_flags single_file is set, it also specifies starting sequence numbers of segment and subtitle filenames. Sometimes it is usefull to have unique starting numbers at each run, but currently it is only achiveable by setting this parameter manually. This patch enables to specify start_number source parameter by introducing hls_start_number_source with 3 possible values: generic/epoch/datetime. This ensures to set start sequence number automatically for practically unique numbers. Generic option is the default and this is the curent behaviour: start_number option value specifies the start sequence number. (start_number default value is 0) If hls_start_number_source is set to epoch, then the start number will be the seconds since epoch (1970-01-01 00:00:00). If set to datetime, then the start sequence number will be based on the current date/time value as YYYYmmddHHMMSS. e.g. 20161231235659. Hls speficication allows 64 bit integers as sequence numbers. This patch also changes some code where only 32 bit integer values were handled correctly.
