* libavcodec: Reduce the size of some arraysAndreas Rheinhardt2019-06-20
| | | | | | | | | | This commit uses smaller types for some static const arrays to reduce their size in case the entries can be represented in the smaller type. The biggest savings came from inv_map_table in vp9.c.

* avformat/segment: fix muxing tmcd tracks in MOVGyan Doshi2019-06-20
| | | | | | avformat/movenc still relies on AVCodecContext time_base to mux tmcd tracks and segment muxer did not copy that field to inner streams leading to SIGFPE in the child muxer instance.
* 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.

* av_format/hlsenc: fix %v handling by format_name functionBodecs Bela2019-06-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hi All, When multiple variant streams are specified by var_stream_map option, %v placeholder in various names ensures that each variant has its unique names. Most of %v handlng is done in format_name function. Currently in this function the result buffer is the same as the input pattern buffer, so you must allocate it before calling format_name function. It also means, that it is silently assumed that the result string will NOT be longer that the pattern string. It is true most of the time, because %v may appear only once in the pattern string and number of variant streams is less than 100 in practical cases. But theoretically it will fail if specified number of variant streams is greater than 100 (i.e. longer than 2 digits). This patch fixes this behaviour by altering format_name function to allocate the result buffer and return it to the caller. Please, review this patch. best, Bela >From 6377ebee8a106a9684d41b270c7d6c8e57cd3e7b Mon Sep 17 00:00:00 2001 From: Bela Bodecs <bodecsb@vivanet.hu> Date: Mon, 17 Jun 2019 14:31:36 +0200 Subject: [PATCH] av_format/hlsenc: fix %v handling by format_name function When multiple variant streams are specified by var_stream_map option, %v placeholder in various names ensures that each variant has its unique names.

* vaapi_encode_mjpeg: fix bad component id bugU. Artie Eoff2019-06-12
| | | | | | | | | | | | | | | | | | | | | | | | | The compound literals assigned to "components" only exist within the scope of the if/else block (thanks Mark Thompson for the better explanation). Thus, after this if/else block, "components" ends up pointing to an arbitrary/undefined array. With some compilers and depending on optimization settings, these arbitrary values may end up being the same value (i.e. 0 with GNU GCC 9.x). Unfortunately, the GNU GCC compiler, at least, never prints any warnings about this. This patch fixes this issue by assigning the constant arrays to local variables at function scope and then pointing "components" to those as necessary. Fixes #7915 Signed-off-by: U.
