The VideoLAN Forums

Hi, i'm using the latest version of vlc for ios(3.4.6) on iOS 16.5.1 and i noticed that some videos are lagging compared to others which are smooth. By activating the debug log option I noticed that in films where the lag occur these error messages appear which in films that go smoothly instead do not appear. I attach below the log messages that appear repeated every time the video lags. I hope you can understand the problem and if you need other info don't esitate to ask me.

What kind of content is this? is this MPEG TS recorded from a digital TV source?

It is a .mkv H.265 movie, I watch many movies through SMB protocol but I don't understand why some movies lag all the time in the same spot even on different devices. There is no problem about SMB because I tried movie with very high bitrate and it run so smootly. I posted in the iOS section but this problem also happens on other devices, I tested my Mac getting the same results. it seems very strange to me because if I play the movie from the windows pc running the SMB server I have no problem playing it.
