      avformat/segment: fix muxing tmcd tracks in MOV · 91f5950f
      Gyan Doshi authored 
      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 names · 86f04b91
      Bodecs Bela authored 
      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 function · 09a48539

      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
