They both give me the same error, for example:Ĭode: Select all $ ffmpeg -i Test.webm -c:v h264_v4l2m2m Test.mp4 h264_vaapi H.264/AVC (VAAPI) (codec h264)įfmpeg tells me that it is aware of the codec h264 with two encoders. h264_v4l2m2m V4L2 mem2mem H.264 encoder wrapper (codec h264) So I looked for an encoder in ffmpeg that I might be able to use.Ĭode: Select all $ ffmpeg -encoders | grep 264 It indicates that the encoder is disabled, which you can see in the output above, "-disable-decoder=aac" seems like an accurate assessment.

To add to the confusion, ffmpeg is also incapable of creating mpeg4 files.
The CODEC is, in fact installed as shown by rpm
