lavf: Add WebM DASH Manifest Muxer
This patch adds the ability to generate WebM DASH manifest XML using ffmpeg. A sample command line would be as follows: ffmpeg \ -f webm_dash_manifest -i video1.webm \ -f webm_dash_manifest -i video2.webm \ -f webm_dash_manifest -i audio1.webm \ -f webm_dash_manifest -i audio2.webm \ -map 0 -map 1 -map 2 -map 3 \ -c copy \ -f webm_dash_manifest \ -adaptation_sets “id=0,streams=0,1 id=1,streams=2,3” \ manifest.xml It works by exporting necessary fields as metadata tags in matroskadec and use those values to write the appropriate XML fields as per the WebM DASH Specification [1]. Some ideas are adopted from webm-tools project [2].
