  • FFmpegKit : "Operation not permitted" in many android devices [closed]

    26 août 2023, par Mrm

    I'm using FFmpegKit 5.1.LTS in my application. A lot of my users have reported that they cannot edit videos (10%). When I tried to obtain their logs, I noticed that many of them are encountering an 'Operation not permitted' error. My users have granted all the necessary storage permissions (READ_EXTERNAL_STORAGE, WRITE_EXTERNAL_STORAGE).

    


    Here is an example :

    


    User device :

    


    Manufacturer : Sony
    
Model : SOG05
    
ABI : [arm64-v8a, armeabi-v7a, armeabi]

    Command :

  • yt_dlp gives a strange message : "Seek to desired resync point failed. Seeking to earliest point available instead." and "File ended prematurely"

    16 septembre 2023, par nikita goncharov

    I have a discord bot (discord.py) in python and it can play music. Lastly it had trouble in playing the music, giving some random warnings but it mostly worked. But now it gives me this message :

    


    [matroska,webm @ 000001570fe92d40] Seek to desired resync point failed. Seeking to earliest point available instead.


    


    [matroska,webm @ 000001570fe92d40] File ended prematurely


    


    and also this one

    


    Warning: program compiled against libxml 211 using older 209


    


    As I saw this is a very common warning but I still have no Idea how to fix it.

    


    I will leave the code of the bot down bellow :

    


    Ytdlp setup (I have renamed the librarie to be youtube_dl)

  • FFmpeg : Re-Streaming RTSP to RTMP (via Nginx) crash randomly with "Connection reset by peer" Error

    5 octobre 2023, par Xav

    I try to Re-stream a RTSP stream from my local network to a RTMP stream (using Nginx), using the following command :

    


    ffmpeg -re -rtsp_transport tcp -i "rtsp://some_ip/Streaming/Channels/101" -vcodec libx264 -f flv -filter:v fps=5 rtmp://127.0.0.1:3500/live/stream


    


    It always starts well and I can watch the resulting stream

    


    But after some random time, it crashes with this output :

    


    av_interleaved_write_frame(): Connection reset by peer49.40 bitrate=6002.5kbits/s speed=0.755x                                        
[flv @ 0x55b00cbd7140] Failed to update header with correct duration.                                                                 
[flv @ 0x55b00cbd7140] Failed to update header with correct filesize.                                                                 Error writing trailer of rtmp://127.0.0.1:3500/live/stream: Connection reset by peer  


    


    Most of time it crashes after 'a few' frames (400 - 800), but some times only after 10 minutes or a day.

    


    I have tried a lot of things found on several forums

    


    The original prompt was

    


    ffmpeg -re -i "rtsp://some_ip/Streaming/Channels/101" -f hevc -filter:v fps=5 rtmp://127.0.0.1:3500/live/stream


    


    with the same error, but at every try and never more than 200 frames.

    


      

    • I added -rtsp_transport tcp -> Same error , but some warnings disappear
    • 


    • I changed the video codec from hevc to flv (I read somewhere hevc was not well supported by rtmp) -> I have seen some improvement. It seems to prevent crashes, but not all the time.
    • 


    


    Thank you for your help
