[FFmpeg-vaapi][mpeg2 decode] failed setup for format vaapi_vld: hwaccel initialisation returned error

[Andrey]

How to reproduce:

ffmpeg -y -hwaccel vaapi -vaapi_device /dev/dri/renderD128 -hwaccel_output_format vaapi -i <1920x1080p_29.97_6mb_mpeg2_high.mpv> -frames 600 -c:v h264_vaapi -b:v 3000k -minrate:v 3000k -maxrate:v 3000k -compression_level 4 -g 256 -bf 2 0008_HD09_1_0.h264

FFmpeg version:
N-93001-g87c165c237

Output:

[mpeg2video @ 0x5615b85d3180] Failed setup for format vaapi_vld: hwaccel initialisation returned error.
Impossible to convert between the formats supported by the filter 'Parsed_null_0' and the filter 'auto_scaler_0'
Error reinitializing filters!
Failed to inject frame into filter network: Function not implemented

This has currently little similarities with a valid ticket: Please provide the command line you tested together with the complete, uncut console output and an input sample that allows to reproduce.

Reproducable only with these streams:
​http://fate-suite.ffmpeg.org/mpeg2/hhi_burst_422_short.bits
​http://fate-suite.ffmpeg.org/mpeg2/xdcam8mp2-1s_small.ts

With all other from ​http://fate-suite.ffmpeg.org/mpeg2/ - works fine.

4:2:2 profile for mpeg2 is not supported by driver(iHD).

$ mediainfo xdcam8mp2-1s_small.ts
Video
ID : 256 (0x100)
Menu ID : 1 (0x1)
Format : MPEG Video
Format version : Version 2
Format profile : 4:2:2@Main

$ vainfo

VAProfileMPEG2Simple : VAEntrypointVLD
VAProfileMPEG2Simple : VAEntrypointEncSlice
VAProfileMPEG2Main : VAEntrypointVLD
VAProfileMPEG2Main : VAEntrypointEncSlice
VAProfileH264Main : VAEntrypointVLD

Moreover, ffmpeg only enables hardware decode support for mpeg2 420 in mpeg12dec.c
4:2:2 hardware accelerate is not supported.

static const enum AVPixelFormat mpeg2_hwaccel_pixfmt_list_420[] = {
#if CONFIG_MPEG2_NVDEC_HWACCEL 
    AV_PIX_FMT_CUDA,
#endif
#if CONFIG_MPEG2_XVMC_HWACCEL 
    AV_PIX_FMT_XVMC,
#endif
#if CONFIG_MPEG2_VDPAU_HWACCEL 
    AV_PIX_FMT_VDPAU,
#endif
#if CONFIG_MPEG2_DXVA2_HWACCEL 
    AV_PIX_FMT_DXVA2_VLD,
#endif
#if CONFIG_MPEG2_D3D11VA_HWACCEL

#endif
#if CONFIG_MPEG2_VAAPI_HWACCEL 
    AV_PIX_FMT_VAAPI,
#endif

    AV_PIX_FMT_VIDEOTOOLBOX,
#endif
    AV_PIX_FMT_YUV420P,
    AV_PIX_FMT_NONE
};

static const enum AVPixelFormat mpeg12_pixfmt_list_422[] = {
    AV_PIX_FMT_YUV422P,
    AV_PIX_FMT_NONE
};

So this issue is invalid and could be closed.
