Package: ffmpeg Version: 7:4.0.2-2+b1 Severity: normal Dear Maintainer,
* What led up to the situation? I am just following the FFmpeg wiki https://trac.ffmpeg.org/wiki/Hardware/VAAPI, and things are not working as documented. * What exactly did you do I first tried the simplest one which should "allows the decoder to work standlone to make decoding faster without any additional options", then I tried to feed the vaapi pixfmt to a vaapi encoder, but both are not working (see below) * What was the outcome of this action? For the first one: $ ffmpeg -hwaccel vaapi -i cut.mp4 -c:v libx264 output.mp4 -y Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'cut.mp4': Metadata: major_brand : isom minor_version : 512 compatible_brands: isomiso2avc1mp41 encoder : Lavf57.56.101 Duration: 00:00:19.99, start: 0.008005, bitrate: 451 kb/s Stream #0:0(und): Video: h264 (High) (avc1 / 0x31637661), yuv420p(tv, bt470bg/unknown/unknown), 640x480 [SAR 1:1 DAR 4:3], 361 kb/s, 29.97 fps, 29.97 tbr, 90k tbn, 2k tbc (default) Metadata: handler_name : VideoHandler Stream #0:1(und): Audio: aac (LC) (mp4a / 0x6134706D), 44100 Hz, stereo, fltp, 111 kb/s (default) Metadata: handler_name : SoundHandler Stream mapping: Stream #0:0 -> #0:0 (h264 (native) -> h264 (libx264)) Stream #0:1 -> #0:1 (aac (native) -> aac (native)) Press [q] to stop, [?] for help [AVHWFramesContext @ 0x7fc91004d2c0] Failed to read image from surface 0x4000018: 20 (the requested function is not implemented).
