* avformat/dashenc: write the styp box when the first frame of a segment is readyJames Almer2020-02-22

* avformat/dashenc: make AdaptationSet id an integer valueJames Almer2020-02-16
| | | | | | | Unlike Representation id, it's defined as an integer in the spec, and not as a string. Signed-off-by: James Almer <jamrial@gmail.com>
* avformat/dashenc: use AV_OPT_TYPE_DICT for http_optsMarton Balint2020-02-03
| | | | | | | | This changes the separator character from comma to colon, but since this option was only added recently I think it should be done for consistency with other similar options. Signed-off-by: Marton Balint <cus@passwd.hu>
* dashenc: check pts to prevent division by zero errorAlfred E. Heggestad2020-01-31
| | | | | | | | | | | | | | | | | | this usecase will cause a division by zero trap: 1. dashenc has received one frame 2. os->max_pts and os->start_pts have same value 3. delta between max_pts and start_pts is 0 4. av_rescale_q(0, x, y) returns 0 5. this value is used as denominator in division 6. Bang! -> segfault this fix checks that max_pts > start_pts. the fix has been tested and works. Signed-off-by: Alfred E.

* avformat/dashenc: add an option to enable low latency Dash manifestJames Almer2020-01-15
| | | | | | | In combination with the streaming option it constrains the value of a few elements, to prevet clients from buffering too much data before starting presentation. Signed-off-by: James Almer <jamrial@gmail.com>

* avformat/dashenc: allow setting fragment durationsJames Almer2020-01-15
| | | | | | | | Implemented as as a frag_duration muxer option and key=value entry in the adaptation_sets muxer option. It has the same syntax as the seg_duration option. A new frag_type option is also introduced to select the kind of fragmentation. Signed-off-by: James Almer <jamrial@gmail.com>
* avformat/dashenc: allow setting segment durations per AdaptationSetJames Almer2020-01-15
| | | | | | | | | Implemented as as a seg_duration key=value entry in the adaptation_sets muxer option. It has the same syntax as the global seg_duration option, and has precedence over it if set. Signed-off-by: James Almer <jamrial@gmail.com>
* avformat/dashenc: Fix leak of AVFormatContext on errorAndreas Rheinhardt2020-01-08
| | | | | | | | | | | The Dash muxer uses submuxers and when one such submuxer has been allocated, it is initially only stored in a temporary variable. Therefore it leaks if an error happens between the allocation and storing it permanently. This commit changes this.

* avformat/dashenc: Added support for Low-latency HLS(Experimental)kjeyapal@akamai.com2018-12-17
| | | | | | | Apple doesn't have an official spec for LHLS. Meanwhile hls.js player folks are trying to standardize a open LHLS spec. The draft spec is available in https://github.com/video-dev/hlsjs-rfcs/blob/lhls-spec/proposals/0001-lhls.md This option will also try to comply with the above open spec, till Apple's spec officially supports it. Applicable only when @var{streaming} and @var{hls_playlist} options are enabled.

* avformat/dashenc: Added an option to ignore io errorskjeyapal@akamai.com2018-12-02
| | | | | When dashenc has to run for long duration(say 24x7 live stream), one can enable this option to ignore the io failure of few segment's upload due to an intermittent network issues. When the network connection recovers dashenc will continue with the upload of the current segments, leading to the recovery of the stream.
