• How to make videos .mp4 for a Phillips Media Player GO GEAR VIBE models ? [closed]

  14 avril 2023, par Ivan Rojas Calvo

  Here is the answer by steps (4/13/23) :

  


  


  1. First download and install the software WinFF here

     


  


  2. Check the specificacions of your media player, mine is the GoGearVibe SA2VBE08K/55 model

     


  


  3. Look for the video specification : mine says that the video format needs to match this specifications :

     


     Format = MJPEG (.mp4)

     


     Resolution = 128 x 128 píxeles

     


     Frames per second = 30 cps (fps)

     


     Bitrate = 512 kpbs

     


  


  4. Read this tutorial to create a preset in WinFF here

     


  


  5. Create a preset that turns ANY mp4 video you have into an MJPEG video with the properties shown above with this info :

     


     name : GoGearVibe55

     


     preset label : MJPEG GOGEAR

     


     Preset command line :

     


     -f mov -vf scale=128:128 -c:v mjpeg -b:v 512k -r 25 -c:a adpcm_ima_wav -b:a 192k -ar 22050 -ac 2


     


     output file : mp4

     


  


  6. Understand how to adapt the code to your necessities with this image
enter image description here

     


  


  


  Do not change what is mark in red, that's the resolution of the screen and the encoder of the video. You can change the value mark in blue, which means the bitrate, more bitrate the video will have more definition without changing the resolution. Tha value in green refers to the fps and the ones marked in yellow is the audio settings, don't worry about that, are good audio settings.

  


  Done. I did'n know how to create an article so I let you try this solution, good luck !

  


• Distribute app with Developer ID with Hardened Runtime and 3rd party CLI-executable - Code sign Error

  22 août 2023, par soundflix

  While I tried to distribute my app with Developer ID from Xcode Organizer, I got this error :

  


  


  Hardened Runtime is not enabled.

  


  "ffmpeg" must be rebuilt with support for the Hardened Runtime. Enable the Hardened Runtime capability in the project editor, test your app, rebuild your archive, and upload again.

  


  


  

  


  Hardened Runtime is enabled in Project > Signing & Capabilites.

  


  My app has the FFmpeg CLI tool in its Resources folder.

  


  Since FFmpeg is a compiled binary, I have no option to enable Hardened Runtime.

  


  How can I solve this and have my app properly code signed ?

  


• How to add a new filter to FFMPEG in c with third-party dependences

  8 avril 2024, par ucag

  I'm a newbie to FFMPEG development and want to add a customized filter to FFMPEG.

  


  I've followed the filter tutorial in the docs. However, it's just a very simplified example and not mentioned how to add other dependences to Makefile. Especially in libavfilter/Makefile, there is only a OBJS-(CONFIG_NAME_FILTER) += name.o for me to add my filter.

  


  I want to add a new video filter with third party dependencies, like third-party c code with some other dependences, third-party compiled .so on Linux, .dylib on Mac, .dll and .lib on Windows, etc.

  


  How can I add these third-party dependences to build process of FFMPEG ?
