• 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)

  


  youtube_dl.utils.bug_reports_message = lambda: ''


ytdl_format_options = {

    'no_warnings': False,
    'default_search': 'auto',
    'source_address': '0.0.0.0',  # bind to ipv4 since ipv6 addresses cause issues sometimes
}

ffmpeg_options = {
    'options': '-vn',
}

ytdl = youtube_dl.YoutubeDL(ytdl_format_options)


class YTDLSource(discord.PCMVolumeTransformer):
    def __init__(self, source, *, data, volume=0.5):
        super().__init__(source, volume)

        self.data = data

        self.title = data.get('title')
        self.url = data.get('url')
        self.duration = data.get('duration')
        img = ""
        imgs = ['']
        for image in data.get("thumbnails"):
            img = image["url"]
            imgs.append(image["url"])
        self.image = img
        self.thumbnails = imgs


  


  The play command :

• 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 :
ffmpeg -y -ss 12.789 -to 32.654  -i "/storage/emulated/0/Movies/lts/lts_20230824_100739.mp4" -filter_complex "[0:v:0] scale=1080:2520,setsar=1/1[v0];[0:a:0]atempo=1.0,volume=1.0[a0]; [v0] [a0] concat=n=1:v=1:a=1[conv][cona];[conv] drawtext=fontfile=/system/fonts/Roboto-Regular.ttf:text=lts edit:x=(w-text_w-69.55932):y=(h-text_h-36.61017):fontsize=84:fontcolor=white:shadowcolor=black:shadowx=5.4915257:shadowy=5.4915257[conv]" -map "[conv]" -map "[cona]"  -c:v libx264 -force_key_frames 'expr:gte(t,n_forced*1)' -preset ultrafast  -r 30  -shortest /storage/emulated/0/Movies/lts/lts_20230826_092915_edited.mp4

• Ffmpeg : How to fix error "Please choose an encoder manually" ?

  9 juillet 2023, par Alex

  I am trying to convert a x265 videofile to a x264 format so it can be played on a television. I am trying the following command

  


  ffmpeg -i input.mkv -f mp4 -vcodec libx264 -preset fast -profile:v main -acodec aac -map 0:0 -map 0:1 -map 0:2 test.mp4


  


  to select videos stream 0:0 for video, stream 0:1 for audio and stream 0:2 for the subtitle. However I get an error

  


  Automatic encoder selection failed Default encoder for format mp4 (codec none) is probably disabled. Please choose an encoder manually.
Error selecting an encoder


  


  How to fix this command ?

  


  P.S. I am not an expert in ffmpeg or videos conversion/formats/encodings/audio formats/subtitle formats.

  


  I found EXACTLY ONE google search result with the exact error phrase HERE. And that is not helping as I do not even understand the first sentence.

  


  Below is the output for the first three streams :

  I found a related question HERE whose answer I do not fully understand. However, I tried the following command

  


  ffmpeg -i input.mkv -f mp4 -vcodec libx264 -preset fast -profile:v main -acodec aac -map 0:0 -map 0:1 -map 0:2 -c:s mov_text  test.mp4


  


  but got a new error

  


  Error initializing output stream: Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height


  


  I thought I am defining an "encoder" for output stream "#0:0" (which I think is video), namely libx264. So what else to do here ?

  


  I tried -acode copy and also to use -qp 0 in the command line which all did not work.
