  • What is the best ffmpeg command keeping the best quality to convert a m3u8 file into a mp4 file ?

    16 novembre 2019, par Nicryc

    Ok so I downloaded a .m3u8 file on the Internet. I saw that this file extension corresponds to a HTTP Live Streaming protocol also called HLS. This protocol consists of an index file (the m3u8 file) that is a text file containing several URL redirecting to .ts files. Those .ts files are video files where each one are a little part of the whole video. Then I searched and found on Wikipedia and on the Apple website that this protocol embeds the MPEG-4 (H.264) video format.

    If I’m not mistaken .mp4 is the file extension of the MPEG-4 (H.264) video format. So a mp4 file is always a MPEG-4 (H.264) video. I use ffmpeg to convert this .m3u8 file into a "normal" video file. Currently I use this command :

    ffmpeg -protocol_whitelist "file,http,https,tcp,tls" -i input.m3u8 output.mp4

    Although even if the video quality is almost perfect it’s a little below the quality of the original m3u8 file. I know I’m really pernickety but is there a better command to keep the original quality ? Or does the ffmpeg convertion command involve inevitably a quality loss ?

  • How to copy metadata exported from mp3 file (with ffmpeg) int another mp3 file

    11 septembre 2022, par Sruly

    I have 2 mp3 files with the same content but with different speed and volume level. I would like to copy the metadata from one to the other and only the metadata. I have seen this post, and was able to extract the metadata to a file. But now when I try to copy the metadata to the second file as described in that post, it copies the whole file as well. This then overwrites the audio itself as well as the metadata.

    


    How can I only copy the metadata into the second file without copying the actual audio.

    


  • How would I delete a file after a remux has been completed using a batch automation file ? [closed]

    10 août 2024, par Voidmaster01

    Ive already automated the process of remuxing to a new file even with new names and all, but how would i go about deleting the original file after the process is completed. currently if i were to run the batch file it would supposedly delete the original file as it was starting the remux, also the remux can take anywhere from a couple of seconds to a couple of hours due to file sizes.

    


    @Echo off
set /p newname=Enter new file name:
ffmpeg -i "V:\Before Remux\01.mkv" -c copy -map 0 "M:\1 REMUX HUB\%newname%.mp4"
Del "V:\Before Remux\01.mkv"
pause


    


    Ive tried using the Del function to delete the file automatically but it deleted the file prematurely causing the file to not be completely processed.
