MediaCodec & Android: crashes with generic error

[filnik]

I've tried to compile by hand the ffmpeg-kit adding the mediacodec. The build should be successful since I'm able to use libopenh264 correctly.

However, if I set the codec to h264_mediacodec I got a generic error :

[amediacodec @ 0xb400007947296700] android.media.MediaCodec$CodecException: Error 0xffffffc3
[h264_mediacodec @ 0xb4000079e3740800] MediaCodec configure failed, Generic error in an external library

and I cannot find a way to make it work. The command I'm using is the following:

val VIDEO_WIDTH = 1080
val VIDEO_HEIGHT = 1920
val BITRATE_MBS = 7 * 1000000 // 7 Mbps
val cmd = mutableListOf(
    "-y",
    "-i", tempInputFile.absolutePath,
    "-vf", "scale=w=$VIDEO_WIDTH:h=$VIDEO_HEIGHT:force_original_aspect_ratio=decrease",
    "-c:v", "h264_mediacodec",
    "-b:v", "$BITRATE_MBS",
    outputPath
)

Any idea to solve the issue would be really appreaciated! Thank you :)

ffmpeg CLI does not support h264_mediacodec or any mediacodec encoder/decoder.

Do you have any reference ffmpeg CLI not supporting h264_mediacodec?
