I've created a series of video segments using dashenc.c from ffmpeg's libav on my windows machine. The mpd file is templated, so it's fairly simple and it passes validation. The video plays, but only if I put ffplay in the same folder as all the files and use:
ffplay -i manifest.mpd If I try to play from some other directory, or even the same directory using: ffplay -i c:\tmp\manifest.mpd or ffplay -i c:/tmp/manifest.mpd The attempt fails, producing this error: [dash @ 0000016ce0d69900] Failed to open an initialization section in playlist 0 [dash @ 0000016ce0d69900] Error when loading first fragment, playlist 0 C:/tmp/manifest.mpd: Invalid argument The mpd file: <?xml version="1.0" encoding="utf-8"?> <MPD xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xmlns="urn:mpeg:dash:schema:mpd:2011" xmlns:xlink="http://www.w3.org/1999/xlink"; xsi:schemaLocation="urn:mpeg:DASH:schema:MPD:2011 http://standards.iso.org/ittf/PubliclyAvailableStandards/MPEG-DASH_schema_files/DASH-MPD.xsd"; profiles="urn:mpeg:dash:profile:isoff-live:2011" type="dynamic" minimumUpdatePeriod="PT500S" suggestedPresentationDelay="PT4S" availabilityStartTime="2020-03-23T14:54:16Z" publishTime="2020-03-23T14:54:25Z" timeShiftBufferDepth="PT4811H53M52.3S" minBufferTime="PT9.6S"> <ProgramInformation> </ProgramInformation> <Period id="0" start="PT0.0S"> <AdaptationSet id="0" contentType="video" segmentAlignment="true" bitstreamSwitching="true"> <Representation id="0" mimeType="video/mp4" codecs="avc1.42001e" bandwidth="5953124" width="720" height="480"> <SegmentTemplate timescale="1000000" duration="5000000" availabilityTimeOffset="4.967" initialization="init-stream$RepresentationID$.m4s" media="media-stream$RepresentationID$-$Number%06d$.m4s" startNumber="1"> </SegmentTemplate> </Representation> </AdaptationSet> </Period> </MPD> Adding in a BaseUrl element didn't help; my guess is I'm formatting it wrong. Any ideas what I might do to fix this?
