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?

    Interesting.

    It seens that nobody want cine profiles in their cameras... Weird. If someone is brave enought to test the vlog request for G80/85 i can upload the file.

  • Vitaliy_KiselevVitaliy_Kiselev

    @Grimor

    Of course upload and link to this topic from G85 one.

    Don't worry, first steps always hard.

  • GrimorGrimor

    @Vitaliy_Kiselev , do you think is risky to send html request to the camera trying to find bugs like early Vlog on Gh4 and now cine D & V on Gx80 and Lx100? Or camera simply will do nothing without any damage? Even when the hack is succesfull you have to store in a custom memory (C1, C2, etc) to prevent it loose when powering down.

    @Grimor

    It is nothing more than modes change, no risk.

    @Grimor V-log is quite awful when recording internally. Cine D is also very average despite many users liking it. Cine V crushes detail in blacks. This could be why there is little interest. From my own tests, Standard & Natural record the best looking images and they cope with color grading very well.

    i like idea of 200Mbps bitrate more than vlog.. :)

  • GrimorGrimor

    Well, we keep on working.

    G80 accept "mov_25p_200mbps".

    camera says OK, menu of video quality became erased (no text info of framerate) and seens to be 1080 due no crop and some type of high bitrate, and records fine... but files can´t be played either on cam or Pc.

    Premiere gives error when importing. 20 seconds file is around 120mb on this mode.

    there are so many thing to test! its purely "trial & error" search .

    This working on GH5?

  • GrimorGrimor

    Probably. First run deploy.html file with "option available" request. Save the html answer and the take your time to see what option is better than original in camera. In example, G80 only goes to 100mbps max, and apppear a few options with 200mbps encoding. Then modify the request from deploy.html with the one you can try. Really easy and no risky at all.

  • GrimorGrimor

    mp4/mov/mp4ed

    24p, c24p, 25p, 30p, 50p, 60p

    100mbps,200mbps

    I tryed almost all this combinations, and only "mov_25p _200mbps" worked. Recorded files seens to be without metadata or info about resolution/bitrate, but not corrupted at all. Someone knows how to recover them? What does "mp4ed" means?

  • alcomposeralcomposer

    Have you tried VLC to playback files? For conversion maybe try ffmpeg?

    This would be amazing! Not only now- but even after the new GH5 firmware we may be able to achieve even higher bitrate. I will test tomorrow. It would be great to get a collection of known working settings. Any chance we can change 60p 4k to 422? ;-)

  • GrimorGrimor

    @alcomposer here is one of those files: https://drive.google.com/open?id=0B10Ows_xNNgHbUEwTk4tU0VWY0U May be a 1080p 25fps 200mbs .mov Hope you can recover it

  • alcomposeralcomposer

    @Grimor have you tried with "Video Repair Software": http://grauonline.de/cms2/?page_id=5

  • GrimorGrimor

    No yet.

  • omega1978omega1978

    Works only version 1.8.you must double the file lenght because in trail you can restore only 50% of the file

  • alcomposeralcomposer

    @omega1978 you got it working?

  • omega1978omega1978

    I' m not at home.will try it tomorrow.

  • GrimorGrimor

    Video repair soft ask for another file in the same format that works ok. I have no "25p 200mbps mov file" to make it work

  • omega1978omega1978

    Take a normal 25p mov file

  • GrimorGrimor

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

  • omega1978omega1978

    No.takes only header from reference file

  • GrimorGrimor

    Ok

  • GrimorGrimor

    Doesnt work

  • 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.
