Whilst XBMC is playing media on screen you can activate the codecinfo pop-up/overlay. This normally appears as white text on a black background bar located near the top of the screen (dependent on the skin being used).
The codecinfo popup displays a number of real time variables describing detailed information on the codecs currently in use.
As of Dharma CodecInfo looks as following:
D(Audio: ac3, 48000hz, 5.1, s16, 448 kb/s) P(aq:99%, kB/s:440.98) D(Video: mpeg2video, yuv420p, 720x480 [PAR 32:27 DAR 16x9], 9800 kb/s) P(vq: 98%, dc:libmpeg2, Mb/S: 3.45, drop:0, pc:2) C( ad: 0.000, a/v: 0.047, edl:-, dcpu: 0% acpu: 0% vcpu:4%) W( fps:23.98 CPU 4 core(s) average: 2.7% )
Sample | Meaning |
---|---|
Audio: ac3, 48000hz, 5.1 | audio codec, sample rate, audio channels |
s16 | bits per sample? |
448 kb/s | current bitrate |
aq:99% | audio queue saturation |
kB/s:440.98 | average bitrate? |
Video: mpeg2video | video codec |
yuv420p, 720x480 | colorspace, resolution |
[PAR 32:27 DAR 16x9] | pixel aspect ratio / display aspect ratio |
9800 kb/s | average bitrate |
vq: 98% | video queue saturation |
dc:libmpeg2 | demux |
Mb/S: 3.45 | current video bitrate |
drop:0, pc:2 | dropped frames, pullup correction pattern length |
ad: 0.000, a/v: 0.047, edl:- | audio delay, a/v sync, edit decision list |
dcpu: 0%, acpu: 0%, vcpu:4% | demuxer cpu, audio cpu, video cpu |
fps:23.98 | frames per second |
CPU 4 core(s) average: 2.7% | 4 cores, CPU usage |
The following example shows some realistic sample data in the approximate form it is displayed:
audio:(mp3lib MPEG layer-2, layer-3) br:128000 sr:48.00 khz chns:2 video:FFmpeg MPEG-4 fps:23.98 512x384 early/late:3/2 fps:23.93 cpu:0.00 dropped:1 Q:0 cache:80% ct:0.05 ac:-0.01
Sample | Full Variable Name | Meaning |
---|---|---|
audio:(mp3lib MPEG layer-2, layer-3) | Audio Codec | Audio decoder used to decode current audio stream |
br:128000 | Bitrate | Bitrate of audio stream (very inaccurate, often plain wrong) |
sr:48.00 khz | Sample rate | Sample rate of audio stream |
chns:2 | Audio Channel Count | Number of audio channels present (very inaccurate, often plain wrong) |
video:FFmpeg MPEG-4 | Video Codec | Video decoder used to decode video stream |
fps:23.98 512x384 | Source Frames Per Second | Frames Per Second in source video |
early/late:3/2 | Early Frames / late Frames | Number of frames that have arrived earlier than expected and later than required. |
fps:23.93 | Actual Frames Per Second | Actual Frames per Second shown onscreen (can vary if you show video in a different resolution than source material) |
cpu:0.00 | CPU Usage | Assume Zero due to some mod quirk? (Bug report on SF 1728041) |
dropped:1 | Dropped Frames | Number of dropped frames |
Q:0 | ? | ? |
cache:80% | Cache | XBMC caches the media locally to ensure continuous uninterrupted playback. If this figure drops it is due to either XBMC or the network struggling to keep up with the data throughput. |
ct:0.05 | Sync Correction | total A-V sync correction done |
ac:-0.01 | ? | ? |
