    Hi Hermat,
    We have build the library using windows visual studio.
    We have used both master and c++11 branch.
    Both the branch got same write violation exception.

    @hermet , I sent an email with sample project with .lib and dll.

    Hi @hermet @smohantty We downloaded the lottie sample player. It works fine. Looks like the lib and ddl we generated in cmake was having some issue. Is it possible for you to provide WIN32 x86 lib and dll rlottie files?
    Our project supports only x86? Thanks

    @Anukeerthana
    How did you generate rlottie.lib out of visual studio? We generated using cmake -G "Visual Studio 14 2015" -DCMAKE_BUILD_TYPE=Debug ..

    Hi @hermet , I have a performance issue with lottie that contains png #452 .
    The performance is too low compare with lottie-android of airbnb
    Do you guy have any plan to update this?

    @sonphan12 hi,
    @sonphan12 Need to discsus @smohantty check the situation also whether is doable or not.
    do you know how resolution of image do you use in the issue case?
    and if you share the resource us to figure out the performance at the exact situation, we might could help you.

    @sonphan12
    2880 × 1800, I know it is quite a high resolution but the problem is Airbnb's lottie-android is really smooth even with this high solution.
    So I expect rlottie can improve since I like this lib a lot and was using it in my production.

    the resource has any confidentials?

    Here is the resource @hermet
    Nothing confidential, feel free to examine it @hermet

    I just checked the resource.
    i'm not sure we can make you satisfied..
    basically rlottie works on sw rasterization though it's fine-tuned,
    image rasterizing won't be better than andorid/ios's..
    because they would perform on gl acceleration.
    lottie embedding image resource is not recommended because it's harmful at scalability.
    rlottie hasn't been optimal at the bitmap rasterization.

    @hermet
    We could check any performance improvement points, but fundamentally it's unlikely to satisfy your device if that kind of high-resolution image is used in rlottie.
    @sonphan12 does it necessary to use that image effect in json?
    Otherwise you can separate image animation from the lottie and implement it using sort of property animation in ui system fundamental functions.
    I think you can play both animation (Image animation + lottie animation) make it same result with good performance.

    @hermet Thank you for the detailed explanation. I understand the problem now. We will re-consider using png inside lottie, seems like we shouldn't do it in the beginning.
    I have a small question. As you said, android performs rasterizing on gl acceleration and rlottie is sw rasterization. But why in normal lottie (not have png), rlottie is way more smoother
    than lottie-android of Airbnb
    Hermet Park
    @hermet
    @sonphan12 it's up to case by case. vector rendering & composition is a little complex to answer.
    @sonphan12 in case of gl in android they might need intermediate frame buffers for lottie animation also composition step. they would take some context switching. Also some vector raster is not suitable with shader logics then normal language functions.
    @sonphan12 so the perforamance is up to how lottie resource is composed wrt specific sequences. just my guess.
    Consequently, rlottie could be faster if more complex vector is used there (not image)

    Hello everyone, I have a curious question about rlottie
    https://github.com/Samsung/rlottie
    is it the same telegram code? https://github.com/DrKLO/Telegram/tree/master/TMessagesProj/jni/rlottie

    Have a nice day.

    @mymedia2
    @nguyenchihungsgu_gitlab yes, it is pretty old version, but it looks slightly patched

    Hello everyone, Can I run file .tgs ( telegram animation sticker) with this lib (https://github.com/Samsung/rlottie)?

    Hello everyone, Can I run file .tgs ( telegram animation sticker) with this lib (https://github.com/Samsung/rlottie)?

    Yes, you can

    Telegram use rlottie itself

    @nguyenchihungsgu_gitlab
    @sonphan12 Do you know any libs using rLottie to run .tgs (not telegram) ?

    thanks.
