| Summary | AMD Radeon 5700 / Navi: VAAPI encoding generates garbled output |
| Product | DRI |
| Version | DRI git |
| Hardware | x86-64 (AMD64) |
| OS | Linux (All) |

Using ffmpeg to encode video to h264/hevc with constant or variable bitrate results in completely garbled output video on navi/radeon 5700 gpu. ffmpeg command used: ffmpeg -init_hw_device vaapi=foo:/dev/dri/renderD128 -hwaccel vaapi -hwaccel_output_format vaapi -hwaccel_device foo \ -i <input file> -filter_hw_device foo -vf 'format=nv12|vaapi,hwupload' -c:v hevc_vaapi -b:v 5000k -maxrate 5000k -f matroska <output file> -This issue also applies to h264 encoding (replace "hevc_vaapi" with "h264_vaapi" above). HW used: AMD Radeon 5700 XT SW used: linux-amd-staging-drm-next-git-5.4.858569.1c2677f991d3-1-x86_64 mesa-git 1:19.3.0_devel.116641.f11ea226664 libva-utils 2.5.0 ffmpeg 1:4.2.1 This issue sounds a bit like BUG 109538, however #109538 speaks of "garbled line at the bottom" where I get completely garbled output, not just at the bottom. In additon, ffmpeg stalls/crashes sometimes as described in #109538 with: [drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring vcn_enc0 timeout, signaled seq=150025, emitted seq=150027 [drm:amdgpu_job_timedout [amdgpu]] *ERROR* Process information: process ffmpeg pid 228611 thread ffmpeg:cs0 pid 228612
