For a TV Project we want to transcode the source videofiles to other formats. The Sourcefiles are fragmented mp4 files. Destination format could be mp4 or any other format. The sourcefile contains multiple audio tracks for different codes (aac, eac3, aac-otherlanguage).
Something with this files is odd. I can play them without problems on quicktime or VLC. Import them into Premiere for example ends up with the video but without sound.
Converting them on AWS MediaConvert results in weird issues as well like (depending on the settings):
- No audio frames decoded on [selector-(Audio Selector 1)-track-1-drc] (selecting aac audiotrack (Track:1))
- Decoder: [Dolby decoder error: failed to configure to stream in first 100 frames] (selecting eac3 audiotrack (Track:2) )
I'm able to convert the files with Handbreak and the result is a MP4 file with one audiotrack which is working everywhere. I'm trying to figure out whats odd with this file to make them working with AWS MediaConvert.
Here is the ffprobe output of one of the files:
