Hi, I am Dylan Fernando. I am a Computer Science student from Australia. I am new to FFmpeg and I wish to apply for GSoC this year. I would like to do the Video filtering with OpenCL project and I have a few questions. Would trying to implement an opencl version of vf_fade be a good idea for the qualification task, or would I be better off using a different filter?
Also, I’m having a bit of trouble with running unsharp_opencl. I tried running: ffmpeg -hide_banner -nostats -v verbose -init_hw_device opencl=ocl:0.1 -filter_hw_device ocl -i space.mpg -filter_complex unsharp_opencl output.mp4 but I got the error: [AVHWDeviceContext @ 0x7fdac050c700] 0.1: Apple / Intel(R) Iris(TM) Graphics 6100 [mpeg @ 0x7fdac3132600] max_analyze_duration 5000000 reached at 5005000 microseconds st:0 Input #0, mpeg, from 'space.mpg': Duration: 00:00:21.99, start: 0.387500, bitrate: 6108 kb/s Stream #0:0[0x1e0]: Video: mpeg2video (Main), 1 reference frame, yuv420p(tv, bt470bg, bottom first, left), 720x480 [SAR 8:9 DAR 4:3], 6000 kb/s, 29.97 fps, 29.97 tbr, 90k tbn, 59.94 tbc Stream mapping: Stream #0:0 (mpeg2video) -> unsharp_opencl unsharp_opencl -> Stream #0:0 (mpeg4) Press [q] to stop, [?] for help [graph 0 input from stream 0:0 @ 0x7fdac0418800] w:720 h:480 pixfmt:yuv420p tb:1/90000 fr:30000/1001 sar:8/9 sws_param:flags=2 [auto_scaler_0 @ 0x7fdac05232c0] w:iw h:ih flags:'bilinear' interl:0 [Parsed_unsharp_opencl_0 @ 0x7fdac0715a80] auto-inserting filter 'auto_scaler_0' between the filter 'graph 0 input from stream 0:0' and the filter 'Parsed_unsharp_opencl_0' Impossible to convert between the formats supported by the filter 'graph 0 input from stream 0:0' and the filter 'auto_scaler_0' Error reinitializing filters!

Should I be running it on a different video file?
