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].
