It doesn't affect file output. Issue is similar to the one originally reported in ticket 5440.

Other shells seem to gloss over that slight mistake but zsh, when run as sh, seems to be very strict. A look into the manual of dash, which claims to be the most POSIX compliant shell, shows that grouped command lists must always be finished with a semicolon. I believe this is also what POSIX says but have not found the text to back up this claim, yet. -- Ticket URL: <https://trac.ffmpeg.org/ticket/9135> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

I have tracked the problem down to BaseURL handling in resolve_content_path. The manifest has a BaseURL in the AdaptationSet and another in the Representation. e.g. URL - http://192.168.1.18:8080/live/manifest.mpd AdaptationSet/BaseURL - video/ Representation/BaseURL - v_34_10000/ The assets are under http://192.168.1.18:8080/live/video/v_34_10000/ but ffmpeg only concatenates the BaseURL with the Root URL (i.e. http://192.168.1.18:8080/live/v_34_10000/) rather than all the parent BaseURLs. I do not have access to the relevant standard so I don't know if concat parents is the expected behaviour (but that seems to be what VLC does). {{{ <?xml version="1.0" encoding="UTF-8"?> <MPD xmlns="urn:mpeg:dash:schema:mpd:2011" id="1614186048" profiles="urn:mpeg:dash:profile:full:2011" type="dynamic" availabilityStartTime="2021-02-24T17:00:49Z" publishTime="2021-02-24T18:02:43Z" minimumUpdatePeriod="PT2S" timeShiftBufferDepth="PT20S" minBufferTime="PT2S"> <Period id="p0" start="PT0S"> <AdaptationSet contentType="video" segmentAlignment="true" mimeType="video/mp4" par="16:9" maxWidth="1920" maxHeight="1080" maxFrameRate="30.00/1001"> <BaseURL>video/</BaseURL> <Representation id="v_34_10000" bandwidth="10000000" width="1920" height="1080" sar="1:1" frameRate="30.00/1001" codecs="hvc1.1.60000000.L93.B0.00.00.00.00.00" startWithSAP="1"> <BaseURL>v_34_10000/</BaseURL> <SegmentTemplate timescale="30030" duration="84084" startNumber="1" media="1614186048_$Number$.m4s" initialization="1614186048_init.mp4"/> </Representation> </AdaptationSet> <AdaptationSet contentType="audio" lang="und" segmentAlignment="true" mimeType="audio/mp4"> <BaseURL>audio/</BaseURL> <Representation id="a_35_SAMPLE_RATE_48000" bandwidth="128000" audioSamplingRate="SAMPLE_RATE_48000" codecs="mp4a.40.2" startWithSAP="1"> <BaseURL>a_35_SAMPLE_RATE_48000/</BaseURL> <AudioChannelConfiguration schemeIdUri="urn:mpeg:dash:23003:3:audio_channel_configuration:2011" value="1"></AudioChannelConfiguration> <SegmentTemplate timescale="48000" duration="134400" startNumber="1" media="1614186048_$Number$.m4s" initialization="1614186048_init.mp4"/> </Representation> </AdaptationSet> </Period> </MPD> }}} -- Ticket URL: <https://trac.ffmpeg.org/ticket/9126> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
