FFmpeg's common filter "v360" missing
26 septembre 2021, par Niklas E.I'm trying to convert a 180° fisheye video to a normal/regular video using the
v360
filter of FFmpeg.

This is the command I tried :

ffmpeg -i in.mp4 -vf "v360=input=fisheye:output=flat:iv_fov=180:v_fov=90" out.mp4


But the output says clearly
No such filter: 'v360'
, although v360 is a common filter listed in docs and other filters I used before worked just fine. I tried updating/reinstalling and looking for solutions, not fixing it.

Why is the filter missing ? How can I debug this ? Should I doe the task using another program entirely ?

Why is my Youtube Video not downloading completely ? "Input buffer exhausted, packet corrupt"
15 septembre 2021, par user16909319Introduction :


I'm working on a Discord Music Bot for personal use only. Basically, when I play a 2min song with the bot, it plays the song for 1min 30secs, then skips it and plays the next one in the queue. The error is shown below :




Error in Pull Function

IO error : Error number -10054 occurred

[mov,mp4,m4a,3gp,3g2,mj2 @ 0000018f86a6f4c0] Packet corrupt (stream = 0, dts = 11154432).

Input buffer exhausted before END element found

Invalid Data found when processing Input

[mov,mp4,m4a,3gp,3g2,mj2 @ 0000018f86a6f4c0] stream 0, offset 0x3e805c : partial file



The code block which I think is causing the problem :


Search song method


async def search_song(self, amount, song, get_url=False):
 info = await self.bot.loop.run_in_executor(None, lambda: youtube_dl.YoutubeDL(ytdl_format_options).extract_info(
 f"ytsearch{amount}:{song}", download=False, ie_key="YoutubeSearch"))
 if len(info["entries"]) == 0: return None

 return [entry["webpage_url"] for entry in info["entries"]] if get_url else info



Play_song method


async def play_song(self, ctx, song):
 url = pafy.new(song).getbestaudio().url
 ctx.voice_client.play(discord.PCMVolumeTransformer(discord.FFmpegPCMAudio(url, executable="C:/ffmpeg/bin/ffmpeg.exe")),
 after=lambda error: self.bot.loop.create_task(self.check_queue(ctx)))
 ctx.voice_client.source.volume = 0.5



Formatting Options I provided :


ytdl_format_options = {
 'format': 'bestaudio/best',
 'outtmpl': '%(extractor)s-%(id)s-%(title)s.%(ext)s',
 'restrictfilenames': True,
 'noplaylist': True,
 'nocheckcertificate': True,
 'ignoreerrors': True,
 'logtostderr': False,
 'quiet': True,
 'no_warnings': True,
 'default_search': 'auto',
 'source_address': '0.0.0.0'
}



Solutions that I've tried :


- 

- Running it on both Replit and locally.
- Redownloading FFmpeg
- Ensuring FFmpeg, pafy, and youtube_dl are all up to date.








Things to Note :


- 

- Playing a 2mins song, it stops after 1min 30 seconds and displays the error above. (75% of the song)
- Playing a 1hr song, it still continues after 10 minutes.






I do not have much experience in this yet so I'm not entirely sure where in my code is actually causing this issue or other ways which I can use to test and fix the issue.
