Main article: Optical disc recording modesĪudio-CDs can be recorded in either disc at once (DAO) or track at once (TAO) mode. Even if two tracks are decompressed and merged into a single track, a pause will usually remain between them. Also, the encoder delay may vary from encoder to encoder, making automatic removal difficult. The popular MP3 format defines no way to record the amount of delay or padding for later removal. Other formats may require extra metadata for the player to achieve the same. Ogg Vorbis), where the start and end are precisely defined, the padding is implicitly trimmed off in the decoding process. Lossless formats are not prone to this problem.įor some audio formats (e.g. If not trimmed off upon playback, the two silences played consecutively over a track boundary will appear as a pause in the original audio content. These silences increase the playtime of the compressed audio data. Lossy audio compression schemes that are based on overlapping time/frequency transforms add a small amount of padding silence to the beginning and end of each track.
Most recent players and newer versions of old players now support gapless playback directly. Some of these rely on third-party gapless audio plug-ins to buffer output. Many older audio players on personal computers do not implement the required buffering to play gapless audio. The two decoded pieces of audio must be fed to the hardware continuously over the transition, as if the tracks were concatenated in software. To account for the whole chain of delays, the start of the next track should ideally be readily decoded before the currently playing track finishes. In extreme cases, the hardware is even reset between tracks, creating a very short "click".
The gap can be as much as half a second or more - very noticeable in "continuous" music such as certain classical or dance genres. If not accounted for, the listener is left waiting in silence as the player fetches the next file (see harddisk access time), updates metadata, decodes the whole first block, before having any data to feed the hardware buffer. Various software, firmware and hardware components may add up to a substantial delay associated with starting playback of a track. When the HDR function was enabled by HDMi 1, it seemed to work ok for the 2 UHD discs I’ve tried.Causes of gaps Playback latency I did notice that without connecting to Port 1, 4K UHD discs were unwatchable though. It streams HDR / 4K material perfectly well and there is no distinction between the type of disc played - in fact DVD’s are probably worse than blu ray discs.
Clementine player stutters during playback tv#
Thinking back, since acquiring the Samsung TV I have had nothing but problems when connecting BD players to it. It also occurs in simple scene changes where there is no processing difficulty that might cause it. I thought it was during big, motion sequences or frantic action sequences but that is not the case.
The tiny little freezes of which there are many (approx 10-15 during last night’s experiment) seem to occur totally randomly. No matter what I tried in the settings this player would not play audio (only video) through HDMI Port 1 (the only one with UHD Color capability) so I connected to Port 2, and lo and behold the exact same issue was there. I wil certainly try the 4.2.2 setting on the Panasonic player to see if it makes a difference but I conducted an experiment last night with a 3rd, non-4K BD player borrowed from a friend.
