Panasonic Imgapp web protocol hacks
  • GrimorGrimor

    Not a hack at all, but really interesting thing.

    Have you seen those new features that can be unlocked to some lumix cameras like Gx80 and Lx100 with web browser using the imgapp web protocol? This is the conversation: http://www.eoshd.com/comments/topic/24995-would-you-perhaps-be-interested-in-a-different-gx8085-colour-profile/

    This is the web file for the browser: https://drive.google.com/file/d/0B10Ows_xNNgHQXNMLWpkZXNkQUE/view?usp=sharing

    In my G80, when Option Availble request is send, this is the camera answer: https://drive.google.com/file/d/0B10Ows_xNNgHR3RDOHdCNUFqLXM/view?usp=sharing

    You can see parts like this:

    item enable="no" id="menu_item_id_ph_sty_vlog_l" option="detail"/

    item enable="no" id="menu_item_id_v_quality_mp4ed_c24p_200mbps"/

    Can a simple .html file unlock vlog or higher bitrates for free on Lumix G80?

    Old topic, but anyone knows if increasing 1080p bitrate on the G80/81/85 via html went any further? @Grimor attempts seem gone pretty close. Just wondering if efforts continued or were communicated in other channels/forums.

    –nostalgic about those colors, mad at the crippled bitrate sky banding.

  • GrimorGrimor

    He's back

  • MarcioKMarcioK

    BTM_Pix reappeared, probably with some good news soon.

  • GrimorGrimor

    No luck. I spent many hours with my G80 and nothing really usefull was found. Interesting things/prototypes was made by @BTM_pix but suddenly he disapear from online comunity. The man is missing, sadly.

    Did anything happen to the 200mbps mode ?

  • samuelcabralsamuelcabral

    Got it! We can only send commands and see if the camera responds.

    Would be awesome if we could copy features from one camera to another. Such as high bitrates, v-log, anamorphic mode...

  • endotoxicendotoxic

    in theory you can command at wish at some point. seem this app is able to control the machine since we do manage to access functions apparently disabled. i wish vitally could unite forces and make a next hack for this series of LSI, since 400mbits on HVECc seem promising.

  • samuelcabralsamuelcabral

    It's a very curious trick... What's the possibilities that something like this can bring us?

  • GrimorGrimor

    User BTM_Pix at eoshd is using "packet capture" for android to study camera-app communication. There are many cameras and many different modes/features for each one to try. Its like a "hide and seek" game.

    @Grimor

    May be we really need to start some combined and open hacking effort.

    I mean, at least he have now simple way to set parameters.

  • GrimorGrimor

    After many requested combinations G80 accepts: <P><A HREF="http://192.168.54.1/cam.cgi? mode=setsetting&type=videoquality&value=mov_25p_100mbps">mov 25p 100MBPS</A></P>

    And

    <P><A HREF="http://192.168.54.1/cam.cgi? mode=setsetting&type=videoquality&value=mov_25p_200mbps">mov 25p 200MBPS</A></P>

    Both generate same .mov corrupt files, so no hight bitrates here.

    If you send http://192.168.54.1/cam.cgi?mode=setsetting&type=colormode&value=vlog_gamma camera accepts and change color profile to "Standar". Weird.

    Keep on searching

  • alcomposeralcomposer

    Don't give up guys. I'm sure this wouldn't have been put into the camera without any real use. I'll play with this when I get time.

  • GrimorGrimor

    Did you try all of them? All?

  • JOFOJOFO

    no HBR mode worked.. :)

  • GrimorGrimor

    If you want to try by yourself here its a html file with plenty of hight bitrates requests: https://drive.google.com/file/d/0B10Ows_xNNgHTWwyaEdIOUU4RWs/view?usp=drivesdk Connect, tryan option, back on browser and repeat.

  • alcomposeralcomposer

    @JOFO on GH2 when you made up super high bitrates it would just bottom out. So it wouldn't do the 'highest available' bitrate- rather some really low 'protection' mode bitrate.

  • JOFOJOFO

    but 41M is a bit low for hw limit as G80 can record 100M 4k video without any issue on 60MB/s cards... I have a feeling that we're not going to get any bitrate or profile hack through protocol hack on G80.. sadly :(

  • alcomposeralcomposer

    @JOFO I think what is happening is similar to what would happen to the GH2. The encoder is stressed out, and then drops to a lower 'protection' mode bitrate. Could be a hardware limitation- both in LSI/ SDCard write speed, or even SDCard slot write speed.

    Then again this may work on GH5 with more powerful LSI & V90 card?

  • JOFOJOFO

    it seems like it's 22 secs video and thus its bitrate is about 41 Mbit/s. So definitely not a 200Mbps encode.. :(

  • alcomposeralcomposer

    Good news and bad news.

    • Treasured can open and repair file: http://aeroquartet.com/movierepair/download
    • Not inexpensive to use Treasured for every single video recorded with camera.
    • Treasured does have a 'software coders' guide, to tell software developers how to achieve same result
    • Without going into more detail with Treasured - I can't tell if the video is 200mbps or simply a lower bit rate yet corrupt.

    Proof attached, hope you don't mind @Grimor that I posted the thumbnails of your video. Also attached price of Treasured service.

    Doesnt work

  • GrimorGrimor

    Ok

  • omega1978omega1978

    No.takes only header from reference file

  • GrimorGrimor

    Reference file doesn't have to be 200mbps too?

  • omega1978omega1978

    Take a normal 25p mov file
