* avformat/hlsenc: deprecate hls_wrap optionSteven Liu2017-02-11
| | | | | | | | | | | | | | When user use the hls_wrap, there have many problem: 1. some platform refersh the old but usefull segment 2. CDN(Content Delivery Network) Deliver HLS not friendly The hls_wrap is used to wrap segments for use little space, now user can use hls_list_size and hls_flags delete_segments instead it.

* avformat/apetag: reorder some code to improve readabilityJames Almer2017-02-10
| | | | | | | | This way it's clear the size field accounts for the footer length plus every tag entry, but not the header. Reviewed-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: James Almer <jamrial@gmail.com>
* avformat/apetag: account for header size if present when returning the start ↵James Almer2017-02-10
| | | | | | | | | | | position The size field in the header/footer accounts for the entire APE tag structure except the 32 bytes from header, for compatibility with APEv1. Reviewed-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: James Almer <jamrial@gmail.com>
* avformat/apetag: fix flag value to signal footer presenceJames Almer2017-02-10
| | | | | | | | | | | | | | According to the spec[1], a value of 0 means the footer is present and a value of 1 means it's absent, the exact opposite of header presence flag where 1 means present and 0 absent. The reason for this is compatibility with APEv1 tags, where there's no header, footer presence was mandatory for all files, and the flags field was a zeroed reserved field.

* vaapi_encode: Add VP8 supportMark Thompson2017-02-08
| | | | | | Fixes ticket #6116. (cherry picked from commit ca62236a89f47bd871eaf69d8d9e837c93c55a6c)
* vaapi_encode: Pass framerate parameters to driverMark Thompson2017-02-08
| | | | | | | | | Only do this when building for a recent VAAPI version - initial driver implementations were confused about the interpretation of the framerate field, but hopefully this will be consistent everywhere once 0.40.0 is released. (cherry picked from commit ff35aa8ca4069bf1543adeec4c28e51e4a012eee)
* vaapi_h264: Enable VBR modeMark Thompson2017-02-08
| | | | | | | | | | Default to using VBR when a target bitrate is set, unless the max rate is also set and matches the target. Changes to the Intel driver mean that min_qp is also respected in this case, so set a codec default to unset the value rather than using the current default inherited from the MPEG-4 part 2 encoder. (cherry picked from commit eddfb57210298a0a94472794485400a3a6c76196)
* vaapi_encode: Support VBR modeMark Thompson2017-02-08
| | | | | | | | This includes a backward-compatibility hack to choose CBR anyway on old drivers which have no CBR support, so that existing programs will continue to work their options now map to VBR. (cherry picked from commit f033ba470fbab1ff6838666d4d86411effa97b27)
* vaapi_encode: Add MPEG-2 supportMark Thompson2017-02-08

* vaapi_h264: Scale log2_max_pic_order_cnt_lsb with max_b_framesMark Thompson2017-02-08
| | | | | | | | | Before this change, it was possible to overflow pic_order_cnt_lsb and generate a stream with invalid POC numbering. This makes sure that the field is large enough that a single IDR B* P sequence uses fewer than half the available POC lsb values. (cherry picked from commit 89725a8512721fffd190021ded2d3f5b42e20e2a)

* vaapi_encode: Fix GOP sizingMark Thompson2017-02-08
| | | | | | | | This change makes the configured GOP size be respected exactly - previously the value could be exceeded slightly due to flaws in the frame type selection logic. (cherry picked from commit 37fab0661a760b2a9d727939d72e629acee1a6ef)
