.TS to MP4/MKV (Lossless?)

[pir8skin]

Hello everyone,

I have a few questions I hope someone could answer for me...

I downloaded a few music videos from vevo.com using ffmpeg

ffmpeg -i "URL_GOES_HERE.m3u8" -c:v copy -c:a copy -bsf:a aac_adtstoasc "NAME_GOES_HERE.mp4"

I'm not very familiar with ffmpeg or video conversion in general, I'd like to make sure that the resulting video file is the same quality as the original.
Will using the above code give me an MP4 file without any loss of quality?


I believe the video file in its original form is a .ts extension, which I can download without any conversion using Internet Download Manager, however, I would still need a way to convert from .ts to mp4/mkv losslessly. Oh, and the reason I want to convert from .ts in the first place is because I experience problems with the video when seeking.

Thanks,
Pir8skin

MKVmerge in the mkvtoolnix package can create the MKV.

No quality loss, but re-wrapping into MP4 or MKV usually won't help with seeking. Can you describe in more detail what those problems are ?

Did you try another video player ? e.g. VLC, MPCHC, Potplayer, SMPlayer ?

Hey poisondeathray,

Thanks for replying, I actually got the ffmpeg code from one of your forum posts LOL. So that code doesn't re-encode the video to mp4... it just re-wraps or remuxes, is that correct? I used vlc player to play the .ts file and when I would try to skip ahead in the video the picture would be blurry with artifacts for like 5 seconds or so before returning to normal. When I play the .mp4 with VLC this does not occur.

Thanks,
