Unit testing android ffmpeg Android Studio The '-acodec' preceding the '-i' option only influences the input audio decoding, not the audio encoding.Posted on March 15, 2023, 5:42 p.m. For example:įfmpeg -acodec libfaad -i input.mov -b 300kbit/s -ar 22050 -o test.flv This uses the libfaad AAC decoder, which is said to be a bit slower than the ffmpeg-builtin, but which decodes the AAC without complaining. Solution: Upgrade to latest ffmpeg and faad library version and add ' -acodec libfaad ' in front of the '-i' switch. In fact it could well be that they'll handle it as an invalid input file. It doesn't look like this will be handled by ffmpeg very soon. This is documented in various bugs (see ffmpeg issues #800, #871, #999, #1733.). The reason for the problem as I understood it is that the ffmpeg-builtin AAC codec cannot handle an audio stream stream with index '1.0'. Still the input video is playable in all standard players (VLC, in Windows.). The resulting video is either unplayable or has no sound.

The message 'Error while decoding stream #0.0' is repeated continuously. Stream #0.1(eng): Audio: libmp3lame, 22050 Hz, 2 channels, s16, 64 kb/sĬhannel element 1.0 is not allocated MOV file you might get the following error: If you are using recent ffmpeg versions to decode a. Update: The workaround for the problem doesn't work for ffmpeg versions more recent than as libfaad support was dropped in favour of the now stable native ffmpeg AAC encoder! If you still have a separate compilation of libfaad you can workaround using the 'faad' encoder tool as described in this post.
