Hello, I see iprima.cz works after last update. Thank you for that. Is there any chance to switch between LQ / HQ? What is default? Thank you again. Tom

The default protocol is HLS.

The default quality is HD (720p), but HD videos only available for RTMP. So if you choose HLS, you'll get HQ (480p) instead of HD.

To change protocol and quality preferences: Options->Preferences..->Plugins->Settings tab, choose iprima.cz, then click "Options" button.

Hello,
unfortunately it seems there was again some change and plugin doesn't work. Instead of video I can only download short clip were is written:

Doslo k chybe, zkuste to prosim pozdeji

One file is attached.

Could you please check it?
Thank you
Tom

Works fine for me. Example link please. Make sure the link works with browser.

FYI since plugin v1.5.0 HD has also been supported for HLS: [wordrider.net].

Link is here:
[play.iprima.cz]

Still works fine:


Maybe it's temporary server problem?

Hi,
iprima.cz plugin for FRD stopped working today morning.
They change the whole web pages (new look) - [play.iprima.cz]
... and they add advertising for videos - before video start playing.

Will be possible to download RTMP in HD again? (FLV file in 1280x720p)?

Thank you.


Sample links for some videos:
[play.iprima.cz]
[play.iprima.cz]

[play.iprima.cz]
[play.iprima.cz]
[play.iprima.cz]

Yes, I can confirm that jimmy's first sample link

http://play.iprima.cz/bursikovy-brikety

fails to be downloaded with v1.5.0 of iprima.cz frp plugin.
The GUI shows the following error:
No string between '"zoneGEO":' and ',' was found
"app.log" is attached...

I first thought that "zoneGEO" implied the programme
was simply blocked for my non-Czech IP, so I went ahead
and tried the link in Firefox:
1. The new iPrima website doesn't like my adblocker
(uBlock Origin), so I had to disable it on "play.iprima.cz"
in order to load the embedded player (wouldn't otherwise) ...
2. After a set of 3-4 ads (as reported by jimmy),
the programme started playing fine, so was not geo-blocked!

I did some preliminary tests and, at least on Firefox on a PC,
RTMP is not being used; the default streaming method is
(unencrypted) AppleHLS. Through Webconsole I sniffed for "m3u8"
URLs and found the master playlist to be:

http://prima-vod-prep.service.cdn.cra.cz/vod_Prima/_definst_/0001/9944/cze-ao-sd1-sd2-sd3-sd4.smil/playlist.m3u8

If you open that in an editor, you'll see
that it points to four "child" playlists, all of whom are
standard def (720x400p), the best quality being:

#EXT-X-STREAM-INF:BANDWIDTH=1667072,RESOLUTION=720x400
chunklist_b1667072.m3u8

You can download that best quality via a recent build of FFmpeg:

ffmpeg -loglevel 8 -stats -i "http://prima-vod-prep.service.cdn.cra.cz/vod_Prima/_definst_/0001/9944/cze-ao-sd1-sd2-sd3-sd4.smil/chunklist_b1667072.m3u8" -c copy "bursikovy-brikety.ts"

(776 MiB file, V=1500Kbps-400p, A=128Kbps)
Optional remux to MP4 container:

ffmpeg -loglevel 16 -stats -i "bursikovy-brikety.ts" -c copy -bsf:a aac_adtstoasc -f mp4 -movflags faststart "bursikovy-brikety.mp4"

(709 MiB file, due to smaller overhead...)
The embedded player does not provide a setting
for HD stream (even when "Video Quality" is set
manually to "MAX", no HD playlists are sniffed... )
Perhaps HD is not offered to free users, it could
well be 720p streams are reserved for those that
do not want the ads and register with their
"Prima Premium PLAY" service (which I would guess
is a paid one... )

I'm pretty sure tong2shot will come up with a solution
for at least downloading the SD HLS streams, more
research is needed whether (hidden) RTMP streams
do exist and whether HD is even still available...

They change the whole thing, so the plugin needs a complete overhaul.

I got this part of playlist (excerpt) :

'tracks': {
    'HLS': [{
        'lang': 'cze',
        'title': 'Čeština',
        'src': 'http://prima-vod-prep.service.cdn.cra.cz/vod_Prima/_definst_/0002/0485/cze-ao-sd1-sd2-sd3-sd4.smil/playlist.m3u8',
        'type': 'application/x-mpegURL',
        'profiles': ['ao', 'sd1', 'sd2', 'sd3', 'sd4']
    }, ],
    'DASH': [{
        'lang': 'cze',
        'title': 'Čeština',
        'src': 'http://prima-vod-prep.service.cdn.cra.cz/vod_Prima/_definst_/0002/0485/cze-ao-sd1-sd2-sd3-sd4.smil/manifest.mpd',
        'type': 'application/dash+xml',
        'profiles': ['ao', 'sd1', 'sd2', 'sd3', 'sd4']
    }, ]
}

From what I tested there are only HLS and DASH streams. And for HLS (we don't have DASH plugin), there are only SD streams with various bitrates.

I'm not sure when will the new plugin be released, we'll see what we can do.

Having as a start-point the SD master playlist I sniffed:

http://prima-vod-prep.service.cdn.cra.cz/vod_Prima/_definst_/0001/9944/cze-ao-sd1-sd2-sd3-sd4.smi/playlist.m3u8

I did some extrapolation and was lucky enough
in my guesswork to arrive at hard-coded HD
playlist URLs that actually work:

http://prima-vod-prep.service.cdn.cra.cz/vod_Prima/_definst_/0002/0485/cze-hd1.smil/playlist.m3u8

Opened in an editor, it reveals:

#EXT-X-STREAM-INF:BANDWIDTH=2310144,RESOLUTION=1280x720
chunklist_b2310144.m3u8

Download 720p AppleHLS stream with FFmpeg:

ffmpeg -loglevel 8 -stats -i "http://prima-vod-prep.service.cdn.cra.cz/vod_Prima/_definst_/0002/0485/cze-hd1.smil/chunklist_b2310144.m3u8" -c copy "bursikovy-brikety_720p.ts"

Specs of the file are:
Video: Resolution=1280x720p, Bitrate=2000Kbps
Audio: Bitrate=256Kbps

...And there's more

http://prima-vod-prep.service.cdn.cra.cz/vod_Prima/_definst_/0002/0485/cze-hd2.smil/playlist.m3u8

Opened in an editor, it reveals:

#EXT-X-STREAM-INF:BANDWIDTH=3334144,RESOLUTION=1920x1080
chunklist_b3334144.m3u8

Download 1080p (FullHD) AppleHLS stream with FFmpeg:

ffmpeg -loglevel 8 -stats -i "http://prima-vod-prep.service.cdn.cra.cz/vod_Prima/_definst_/0002/0485/cze-hd2.smil/chunklist_b3334144.m3u8" -c copy "bursikovy-brikety_1080p.ts"

File specs are:
Video: Resolution=1920x1080p, Bitrate=3000Kbps
Audio: Bitrate=256Kbps
(Be warned that this HD stream produces huge files;
a 1min long test 1080p download, after the remux
to MP4, measures at 24.6 MiB; so a full 1hr long
programme would be aprox. 1.43GiB...)

Hoping my findings are of value to the devs,
although, understandably, hard-coded playlists
constitute a very fragile hack - we have to find
another way to get to those HD streams...
