youtube-dl: mewatch unable to download video; Unable to download JSON metadata

I am not sure how I can help but I hope my info can help in some way.

Say I wanted to download this video link, https://www.mewatch.sg/watch/The-Star-Athlete-E9-Floorball-368951

It creates a .mpd file where it shows that files are hosted on cloudfront.net

And with the .mpd file, I could play the stream via VLC.

And these are the content of the .mpd file <?xml version="1.0"?> <MPD xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="urn:mpeg:dash:schema:mpd:2011" xsi:schemaLocation="urn:mpeg:dash:schema:mpd:2011 http://standards.iso.org/ittf/PubliclyAvailableStandards/MPEG-DASH_schema_files/DASH-MPD.xsd" type="static" mediaPresentationDuration="PT2727.080S" minBufferTime="PT4S" profiles="urn:mpeg:dash:profile:isoff-main:2011"> <Period> <AdaptationSet id="1" segmentAlignment="true" maxWidth="1920" maxHeight="1080" maxFrameRate="25"> <SegmentTemplate timescale="1000" media="https://d1gbibt4vs5yna.cloudfront.net/dash/p/2082311/sp/208231100/serveFlavor/entryId/1_4n8bmm4x/v/1/pv/1/ev/17/flavorId/1_,a5kbb1y2,f1tmjacw,dze9tizj,lcfh661u,9szc627d,c8c75745,/forceproxy/true/name/a.mp4.urlset/fragment-$Number$-$RepresentationID$.m4s" initialization="https://d1gbibt4vs5yna.cloudfront.net/dash/p/2082311/sp/208231100/serveFlavor/entryId/1_4n8bmm4x/v/1/pv/1/ev/17/flavorId/1_,a5kbb1y2,f1tmjacw,dze9tizj,lcfh661u,9szc627d,c8c75745,/forceproxy/true/name/a.mp4.urlset/init-$RepresentationID$.mp4" duration="4000" startNumber="1"> </SegmentTemplate> <Representation id="f1-v1-x3" mimeType="video/mp4" codecs="avc1.42c01e" width="640" height="360" frameRate="25" sar="1:1" startWithSAP="1" bandwidth="715430"> </Representation> <Representation id="f2-v1-x3" mimeType="video/mp4" codecs="avc1.42c01e" width="854" height="480" frameRate="25" sar="1:1" startWithSAP="1" bandwidth="1293595"> </Representation> <Representation id="f3-v1-x3" mimeType="video/mp4" codecs="avc1.42c01f" width="960" height="540" frameRate="25" sar="1:1" startWithSAP="1" bandwidth="1811971"> </Representation> <Representation id="f4-v1-x3" mimeType="video/mp4" codecs="avc1.42c028" width="1280" height="720" frameRate="25" sar="1:1" startWithSAP="1" bandwidth="2434897"> </Representation> <Representation id="f5-v1-x3" mimeType="video/mp4" codecs="avc1.640028" width="1920" height="1080" frameRate="25" sar="1:1" startWithSAP="1" bandwidth="3945434"> </Representation> </AdaptationSet> <AdaptationSet id="2" segmentAlignment="true"> <AudioChannelConfiguration schemeIdUri="urn:mpeg:dash:23003:3:audio_channel_configuration:2011" value="1"/> <SegmentTemplate timescale="1000" media="https://d1gbibt4vs5yna.cloudfront.net/dash/p/2082311/sp/208231100/serveFlavor/entryId/1_4n8bmm4x/v/1/pv/1/ev/17/flavorId/1_,a5kbb1y2,f1tmjacw,dze9tizj,lcfh661u,9szc627d,c8c75745,/forceproxy/true/name/a.mp4.urlset/fragment-$Number$-$RepresentationID$.m4s" initialization="https://d1gbibt4vs5yna.cloudfront.net/dash/p/2082311/sp/208231100/serveFlavor/entryId/1_4n8bmm4x/v/1/pv/1/ev/17/flavorId/1_,a5kbb1y2,f1tmjacw,dze9tizj,lcfh661u,9szc627d,c8c75745,/forceproxy/true/name/a.mp4.urlset/init-$RepresentationID$.mp4" duration="4000" startNumber="1"> </SegmentTemplate> <Representation id="f2-a1-x3" mimeType="audio/mp4" codecs="mp4a.40.2" audioSamplingRate="44100" startWithSAP="1" bandwidth="93589"> </Representation> <Representation id="f4-a1-x3" mimeType="audio/mp4" codecs="mp4a.40.2" audioSamplingRate="44100" startWithSAP="1" bandwidth="125588"> </Representation> <Representation id="f6-a1-x3" mimeType="audio/mp4" codecs="mp4a.40.2" audioSamplingRate="44100" startWithSAP="1" bandwidth="64001"> </Representation> </AdaptationSet> </Period> </MPD>

I just realized what is being asked for ToggleIE and the url format no longer exists. All of them are in the MeWatchIE format now. So we can just go with MeWatchIE and not bother with ToggleIE format

This MeWatchIE._real_extract() seems to work:

    def _real_extract(self, url):
        video_id = self._match_id(url)
        webpage = self._download_webpage(
            url, video_id, note='Downloading video page')
        page_data = self._search_regex(
            r'(?s)window\s*\.\s*__data\s*=\s*(\{.*?\})\s*</script>',
            webpage, 'hydration JSON')
        page_data = self._parse_json(page_data, video_id)
        partner_id = traverse_obj(
            page_data, ('app', 'config', 'playback', 'kalturaThumbnailBaseUrl'),
            expected_type=lambda u: (url_or_none(u) or '').rstrip('/').rpartition('/')[2] or 2082311)
        show_data = traverse_obj(page_data,
                                 ('cache', 'page', Ellipsis, 'entries',
                                  lambda _, v: v['item']['id'] == video_id),
                                 get_all=False)
        
        entry_id = traverse_obj(show_data, ('item', 'customFields', 'EntryId'))

        txt_or_none = lambda x: x.strip() or None

        return merge_dicts(
            {'_type': 'url_transparent'},
            self.url_result(
                'kaltura:%s:%s' % (partner_id, entry_id), ie='Kaltura', video_id=video_id),
            {
                'title': traverse_obj(show_data, 'title', ('item', ('title', ('customFields', 'sortTitle'), 'episodeName')),
                                      get_all=False, expected_type=txt_or_none) or self._generic_title(url),
                'description': traverse_obj(show_data, ('item', ('description', 'shortDescription')), get_all=False, expected_type=txt_or_none),
                'uploader': traverse_obj(show_data,('item', 'distributor'), expected_type=txt_or_none),
                'categories': traverse_obj(show_data,('item', 'genres', Ellipsis), expected_type=txt_or_none),
                'episode_number': traverse_obj(show_data,('item', 'episodeNumber'), expected_type=int_or_none),
                'episode': traverse_obj(show_data, ('item', 'episodeName'), expected_type=lambda x: re.sub(r'^Ep\s+\d+\s+(.*?)\s*$', r'\1', x) or None),
                'season_id': traverse_obj(show_data, ('item', 'seasonId'), expected_type=txt_or_none),
                'series_id': traverse_obj(show_data, ('item', ('showId', ('season', 'show', 'id'))), get_all=False, expected_type=txt_or_none),
                'season_number': traverse_obj(show_data,('item', 'season', 'seasonNumber'), expected_type=int_or_none),
                'season': traverse_obj(show_data, ('item', 'season', 'title'), expected_type=txt_or_none),
                'series': traverse_obj(show_data, ('item', 'season', 'show', 'title'), expected_type=txt_or_none),
            })

I didn’t investigate how ToggleIE should be updated. The first test fails in the same way as the MeWatch pages.
