  • flash/modules/global/app/ffmpeg.exe is Non-Executable

    30 octobre 2013, par Juan Rocamonde

    I cannot install dolphin. Always it returns back the same error :

    The following files have inappropriate permissions:
      flash/modules/global/app/ffmpeg.exe;


    And if I scroll down, I can se this :
    flash/modules/global/app/ffmpeg.exe -- Non-Executable
    And I made it executable, chmod777 and I didn't work, so I tried with chmod755 and all chmods with executable parametres. And it didn't work anyway.
    Help please ! I need to get this working asap, is for a business !
    Thanks people.

  • Parsing NAL units using FFMPEG

    6 novembre 2013, par 2ndlife

    I am new to MPEG-4 and taking baby steps to learn it. I am using FFMPEG as reference.

    1. I understand that all mpeg-4 are encoded into NAL units and wrt to FFMPEG av_read_frame() function returns one NAL unit, Am I right ? Is frame a NAL unit ? (though it can be a combination of multiple NALs)

    2. I also saw that h264_parser.c implements a function called h264_parse which is calling parse_nal_units() inside, If i need to get NAL units how can I use this parse_nal_units from my main function ?

    3. What is av_parse_Parse2() function do ? does it return decoded NAL units ?

    4. OR FFMPEG has -vbsf h264_mp4toannexb switch to dump raw NAL units, Can somebody help me understand how I can use the same from my main function ?

    Please help me out here...

  • How to convert a GIF to optimized mp4 video using FFMPEG on android ?

    6 novembre 2017, par Omar Hezi

    I successfully integrated FFMPEG as a library on android and I am using JNI to communicate my JAVA classes with C and C++ classes.

    Background and my question
    A chat app where GIFs can be sent, the issue is that one GIF could weigh up to 2MB, after a lot of research I found that the best solution is converting those gifs to mp4 (Something that Facebook messenger, whatsapp and telegram do).

    My question is, how can I convert a gif to mp4 in order to reduce its size, using ffmpeg (not in command line, in android) as Telegram mentions here ?

    What I have attempted

    • Understanding and implementing the gifvdeo.cpp from Telegram (it was extremely complicated and I could not understand it fully)
    • Converting the gif to frames of bitmaps, and compressing each bitmap and then converting those bitmaps to mp4 (I was not able to pass the bitmap object to C through JNI because of " Fatal signal 11 (SIGSEGV), code 1, fault addr 0x31f in tid 26952" which is another question)

    Research I have done

    the problem with above questions is that they use command line FFMPEG which is not what I am doing, I am using JNI and direct access to c classes of mentioned library.
