  i have made a music bot with discord.py, but i get this info thing and it doesnt work anymore error [youtube] QxYdBvB8sOY: Downloading webpage 985104597242773505 [2022-06-25 07:45:51] [INFO    ] discord.player: Preparing to terminate ffmpeg process 37580.

  its weird since all the other code in my bot works fine like the !info command, so it must be an error with either youtube-dl or ffmpeg. But then again it doesnt join the voice call in the first place so that might be the error. i added ffmpeg to path but i still wrote the path to it here player = discord.FFmpegPCMAudio(song, **ffmpeg_options, executable="C:\\Users\\jonas\\Documents\\ffmpeg-2022-06-16-git-5242ede48d-full_build\\ffmpeg-2022-06-16-git-5242ede48d-full_build\\bin\\ffmpeg.exe"). i followed this tutorial for the bot https://www.youtube.com/watch?v=Q8wxin72h50&t=1040s i did everything he did but it didnt work. My discord.py version is 2.0.0 my Python version is 3.10.5 and my youtube_dl version is 2021.12.17 my ffmpeg download is ffmpeg-2022-06-16-git-5242ede48d-full_build. I tested it on discord.py 1.73 and it worked fine. This was in intellij though whilst my main program is in Visual Studio Code but i couldnt see it making any big difference so it could be the intents that makes the program not work.I couldnt see any mistakes in the code but im new to discord.py, youtube_dl and ffmpeg stuff so unless visual studio code showed me what i did wrong, i wouldnt notice. But what did i do wrong and how can i fix it ?

  


• FFmpeg encoding in c

  25 décembre 2012, par barisatbas

  I have been working on a project about video summarization on android platfrom. and I am stuck in encoding. I think ;
  first I must convert my frame into RGB Frame, then convert that RGB FRame into YUV Frame. Then encode the frame. After this operations, The output video was so weird. I think I missed something. Here is my las optimized code. Maybe someone has an experiement in this subject.

  Its syntax is changed according to android ndk syntax :

• Ffmpeg conversion from RTSP to RTMP stops transmitting video in a Odroid C4 device

  14 mars 2023, par JuanN

  We hace a video camera (transmitting using RTSP) connected to an Odroid C4. We want to send the streaming to a OvenMediaEngine using RTMP. For us to achieve this goal, we run this command :

  


  ffmpeg -rtsp_transport tcp -nostdin -i "rtsp://admin:xxxxxx@aaa.aaa.a.aaa:ppp//h264Preview_01_sub" -threads 1 -cod
ec copy -f flv -flvflags no_duration_filesize -an "rtmp://xxxxx.xxxx.xx:pppp/xxxxxxx"


  


  Apparently the transmition is fine but, after a while (this "while" ranges from a few hours to a few days) the ffmpeg command stops working, with the following message [rtsp @ 0x55a46347b0] CSeq 3005 expected :

  We thought at first this was due to the limitation of ffmpeg when it is run on background (that's the reason for the nostdin option), but it keeps on failing. Looking online, we also found that it could be some issue of the file size (hence the no_duration_filesize option).

  


  The weird part is the process is still running (if you check it using a top or ps command) when it fails, but it has to be rebooted to resume the transmision.

  


  Any clues will be most welcome !
Thank you.
