What you were trying to accomplish?
I am trying to transcode an mp4 file using the mediacodec encoder support
recently added by Zhao Zhili here
(https://git.ffmpeg.org/gitweb/ffmpeg.git/commit/0ff18a7d6d496f89d9e007ddd1cad7116baf5c7c)
The problem you encountered:
Currently, only on emulators with OS API levels less than API 31, The
output video is simply gibberish with a repetitive pattern of red, purple,
or random colors
The exact command line you were using:
-hwaccel mediacodec -hwaccel_output_format mediacodec -i
"/data/user/0/com.test.ffmpeg_kit_android_demo/cache/test_input.mp4" -c:v
h264_mediacodec -ndk_codec 1 -y
"/data/user/0/com.test.ffmpeg_kit_android_demo/cache/test_output.mp4"
-loglevel trace
