[kdemultimedia] [Bug 416466] GoPro footage thumbnails are just noise in Dolphin
https://bugs.kde.org/show_bug.cgi?id=416466 --- Comment #12 from Iyán Méndez Veiga --- Despite latest changes in Dolphin, this is still true with latest version. Kdenlive creates thumbnails perfectly, but Dolphin doesn't. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=416466 --- Comment #11 from Iyán Méndez Veiga --- Of course, the naive patch doesn't solve the real problem (and it breaks the thumbnails for good videos). While keep reading the code, ffmpeg docs, etc., I found these issues with GoPro videos that may be related. https://github.com/opencv/opencv/issues/15352 So I closed the MR and I'm afraid I cannot help more without external help. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=416466 --- Comment #8 from Iyán Méndez Veiga --- It looks like some problem with the swscaler. This is the output of running ffmpegthumbtest with the two files I provided before.

Also, when trying the command suggested by Christoph I have no issues at all. I have also tried to disable the filmstrip effect, but same issue. What is weird is that some videos have a thumbnail but others (most of them) not. Here I leave two files so you can compare and try to debug. https://file.io/qY9Dr5lR (thumbnail not working) https://file.io/dVpq7bha (thumbnail working) Both videos are taken directly from the gopro and they are not edited. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=416466 --- Comment #1 from Christoph Feck --- The thumbnailer just uses FFMPEG libraries to extract the frame image. Please try this command in Konsole (try with different time-stamps): ffmpeg -ss 00:00:10 -i GXxx.MP4 -vframes 1 testoutput.jpg If the testoutput.jpg shows the same errors, then the bug needs to be reported to FFMPEG developers. -- You are receiving this mail because: You are watching all bug changes.
