• Facebook Reels Upload always failing

}


  


  It seems the error code 1363008 is related to the video properties format but even after following Facebook Reels video format recommandations, I can't make it work.

  


  Can you help me with this please ?

  


  I failed getting usefull help with ChatGPT 😅, and thanks in advance for anyone who answers or comments my question.

  I have tried asking ChatGPT, Gemini, or Bing, and they always lead me into a loop of errors that cannot be resolved. This error only occurs when the song naturally finishes playing due to its duration. If the song is playing and I use the command !skip, the next song in the queue will play and function normally. I noticed that it seems like if a song ends naturally, the song queue is also cleared immediately. I hope someone can help me with this

  


• When using libva* (ffmpeg) encoded GIF images, an error is reported when compiling the demo

  10 août 2023, par yangjinhui2936

  issuse : I need to use the GIF encoding feature in FFMPEG to encode argb images as gifs.Because the encoding effect of using GIF library is not as good as the effect of FFMPEG.
However, several libraries like avcodec were too bulky, so I did some cropping.I just want to keep the functionality of GIF encoding.
Below is my makefile for cropping ffmpeg :

  Then link the compiled so to the gif demo.
Blew is gif demo code(He was automatically generated by chatgpt, and I want to verify it) :

  Belw is shell of compile script for gif :

  


  #!/bin/sh
gcc -o x2gif x2gif.c -L ./output/lib/ -l:libavformat.a -l:libavcodec.a -l:libavutil.a -lz -I ./output/include/


  


  Unfortunately, the compilation did not pass.
How can I troubleshoot and resolve this issue ?
