Hello everyone,

I am converting .mp4 to hls and m3u8 and it works fine. However, for some videos, I am getting the following error.

here is my code:

 video = ffmpeg_streaming.input(s3_bucket_url)
 logger.info(f"starting hls conversion")
 hls = video.hls(Formats.h264())
 logger.info(f"starting hls representations")
 hls.auto_generate_representations()
 logger.info(f"done with hls representations")
 timestamp_str = DT.now().strftime("%Y%m%d%H%M%S")
 hls_name = f"{video.id}_{timestamp_str}__hls.m3u8"
 hls_object_key_local = (
 f"{settings.MEDIA_ROOT}/videos/{video.id}/{hls_name}"
 )
 logger.info(f"starting with hls output")
 
 hls.output(hls_object_key_local)
 logger.info(f"done with hls output")

The code crashes at hls.output(hls_object_key_local) for some videos but not all

The error message:
