@@ -20,8 +20,18 @@ clip | expectation | results
720-mp4-h264-60fps | ~~my computer struggles to play this~~ think just a laggy video | plays suprisingly well - never lags on custom start
1080-avi-mpeg4.avi | i think this should play ok | does play - sometimes struggles to load the next loop though - similar to the other 1080 one but a bit better (seems to load if current video is paused)
1080-flv-flv1.flv | wouldnt expect/need flv with custom codec | omx doesnt reconise codec
1080-mkv-h264-60mbps.mkv | dont expect this to work | suprizingly this video played though on pi (didnt even open on my computer.) however is showing a weird new bug where when the video finished , the next one wont load but also wont error...
1080-mp4-h264.mp4 | hopefully this plays okay ?? | this wouldnt load , error getting video length : `dbus exception no reply` (although it played ok in normal omxplayer)

error-mkv-mpeg4.mkv | should fail but not sure how.. | just wont load
an interesting note : all the videos above behaved the same on hdmi and composite out except for 1080-mp4-h264 which didnt have the failing to load next problem , instead , would flash green for a bit at the start of each clip even on custom starts
an interesting note : ~~all the videos above behaved the same on hdmi and composite out except for 1080-mp4-h264 which didnt have the failing to load next problem , instead , would flash green for a bit at the start of each clip even on custom starts~~ this also started happening on hdmi out - seems to be unpredictable how it handles 1080p files
## the same mp4 video at different resolutions
i use adobe premiere to edit videos. i imported a raw 10s mts file from a digital camera and exported 3 times : 480 , 720 and 1080. these three were loaded and tested on recur :
- 480 played fine - no lags when custom starting (both on hdmi and composite)
- 720 played ok - video played through and loaded all good. sometimes would lag on custom start point , seemed to be better / not do this when composite out mode
- ~~1080 doesnt work - the video can play through once alright , but it seems like the omxplayer/dbus connection cant load another 1080 file while an existing 1080 file is playing~~
UPDATE: turns out the 1080 files couldnt load because the pi hadnt been assigned enough memory to its gpu . i added `gpu_mem=448` to the config.txt and now 1080 videos seem to load and loop just fine. (still sometimes lags when change is triggered/ custom start)
