[Petr Nejedly]

This is needed to deliver video to iOS devices without player transcoding.

From Andy:

ffmpeg -vsync cfr -f $pipefmt -i "$fifo" \
      -map 0:0 -map 0:1 \
      $audio_options -r:a $AR -b:a ${BA}k \
      $video_options -profile:v $P $video_extra \
      -g $keyint -keyint_min $[keyint/2] -r:v $R -b:v ${BV}k \
      -s $S -vf "$dt" \
      -flags -global_header -threads 0 \
      -f segment -segment_time $gop -segment_format mpegts \
      "$frag" < /dev/null

Android devices running 3.0+ (and some runing 2.3) seem to have fairly good support for HTTP Live Streaming via the built in media libraries, which would make writing a custom video player with seek support across Medium/Low qualities for ServiiGo much easier. Please let me know when you start on this so I can do some testing at the same time.

It seems that Sony 2013 models support HTTP Live Streaming format in native:

application/x-mpegURL or vnd.apple.mpegURL (.M3U8) Index Files (Playlists)

video/MP2T (.ts) Media Segment Files

exemple of M3U8 :

#EXTM3U
#EXT-X-TARGETDURATION:10
#EXT-X-MEDIA-SEQUENCE:1
#EXTINF:10,
http://media.example.com/segment0.ts
#EXTINF:10,
http://media.example.com/segment1.ts
#EXTINF:10,
http://media.example.com/segment2.ts
#EXT-X-ENDLIST
