Common Issues
| Symptom | What to check |
|---|---|
Unknown decoder/encoder | Use ffmpeg -version and ffmpeg -encoders/-decoders to verify the active build |
| MPP/RGA device cannot be opened | Check device nodes, user groups, kernel drivers, and the DTS |
RGA reports No hw context provided | Add -hwaccel_output_format drm_prime when decoding |
| RGA rejects a format or size | Try a common format such as nv12, and check dimension and crop-coordinate alignment |
| CPU usage remains high with hardware acceleration | Check whether software filters are causing hwdownload and hwupload operations |
| A format cannot be hardware-decoded | Check whether the target SoC supports the codec, bit depth, profile, and resolution |
