* libavfilter/vf_scale: Ensure scaled video is divisible by nLars Kiesow2019-08-13
| | | | | | | | | | | | | | | | | | | | This patch adds a new option to the scale filter which ensures that the output resolution is divisible by the given integer when used together with `force_original_aspect_ratio`. This works similar to using `-n` in the `w` and `h` options. This option respects the value set for `force_original_aspect_ratio`, increasing or decreasing the resolution accordingly. The use case for this is to set a fixed target resolution using `w` and `h`, to use the `force_original_aspect_ratio` option to make sure that the video always fits in the defined bounding box regardless of aspect ratio, but to also make sure that the calculated output resolution is divisible by n so in can be encoded with certain encoders/options if that is required.

* vp9_metadata: Improve spec-compliance and warningsAndreas Rheinhardt2019-07-28
| | | | | | | | | | | | | | | | | | The earlier version had three deficits: 1. It allowed to set the stream to RGB although this is not allowed when the profile is 0 or 2. 2. If it set the stream to RGB, then it did not automatically set the range to full range; the result was that one got a warning every time a frame with color_config element was processed if the frame originally had TV range and the user didn't explicitly choose PC range. Now one gets only one warning in such a situation. 3. Intra-only frames in profile 0 are automatically BT.601, but if the user wished another color space, he was not informed about his wishes being unfulfillable. The commit also improves the documentation about this. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>

* dump_extra: Don't add extradata if it already existsAndreas Rheinhardt2019-07-14
| | | | | | | | | | | | | | | | | | | | | The dump_extra bitstream filter currently simply adds the extradata to the packets indicated by the user without checking whether said extradata already exists in the packets. Besides wasting space duplicated extradata in the same packet/access unit is also forbidden for some codecs, e.g. MPEG-2. This check has been added to be able to use the mpeg2_qsv encoder (which only adds the sequence headers to the first packet) in broadcast scenarios where repeating sequence headers are required. The check used here is not perfect: E.g. dump_extra would add the extradata to a H.264 access unit consisting of an access unit delimiter, SPS, PPS and slices. Fixes #8007.

* avformat/hlsenc: temp_file usage for master playlist and vtt playlistBela Bodecs2019-06-28
| | | | | | | | | | | | | currently master playlist and subtitle playlist creation does not use temporary files even when temp_file flag is set. Most of the use cases it is not a problem because master playlist creation happens once on the beginning of the whole process. But if master playlist is periodically re-created because of master_pl_refresh_rate is set, non-atomic playlist creation may cause problems in case of live streaming. This patch correct this behavior by adding this functionality. Reviewed-by: Steven Liu <lq@onvideo.cn> Signed-off-by: Bela Bodecs <bodecsb@vivanet.hu>

* avformat/hlsenc: better error log message for var_stream_map contentBela Bodecs2019-06-24
| | | | | | | | | | | | When multiple variant streams are specified by var_stream_map option, %v is expected either in the filename or in the last sub-directory name, but only in one of them. When both of them contains %v string, current error message only states half of the truth. And even %v may appears several times inside the last sub-directory name or in filename pattern.

* avformat/hlsenc: enhanced %v handling with variant namesBodecs Bela2019-06-20
| | | | | | | | | | | | | | | | When multiple variant streams are specified by var_stream_map option, %v placeholder in various names ensures that each variant has its unique names. Currently %v is substituted by its variant index value (0, 1, 2 etc.). In some use cases it would be handy to specify names for variants instead of numerical indexes. This patch makes it possible to use names instead of default indexes. In var_stream_map option each or some of the variant streams may use an optional name attributum (e.g. -var_stream_map "v:0,a:0,name:sd v:1,a:1,name:720p") If a name is specified for a variant, then this name value will be used as substitution value of %v instead of the default index value.
