I tried porting my windows opencv application to my linux board, olimex a20 (armhf) and i get,
No accelerated colorspace conversion found from yuv420p to bgr24 warning continuously when reading an mp4 or avi file.
And performance is extremely poor.
After a bit of searching i found that the problem is with ffmpeg, so i manually built ffmpeg to the latest snapshot,
libavutil 55. 11.100 / 55. 11.100
libavcodec 57. 20.100 / 57. 20.100
libavformat 57. 20.100 / 57. 20.100
libavdevice 57. 0.100 / 57. 0.100
libavfilter 6. 21.101 / 6. 21.101
libswscale 4. 0.100 / 4. 0.100
libswresample 2. 0.101 / 2. 0.101
libpostproc 54. 0.100 / 54. 0.100
but still it didnt help. Then i compiled opencv 3.0.0 on the board. But still the problem persists. Please help!
