Create MP4 video with sound compatible with many media players and devices

edited February 2014 in Support
-Objective : Create an out of the box MP4 video with sound compatible with many media players and devices
-Status: Failed partially (it is possible to create an MP4 video that unfortunately must not contain audio track or else it will have a very limited compatibility)
1. Container
a. Type=MP4 (Passed - included in Camstudio 2.7.2)
2. Video track
a. Encoding Format=H.264/MPEG-4 AVC (Passed aided by third party codec; used x264vfw though may not be the only one)
b. Profile=High (Passed - profile available in x264vfw)
3. Audio track
!a.Encoding Format=Low Complexity AAC (LC-AAC)(Failed: I couldn't find any encoder for this)
1. LC-AAC encoder;
2. Camstudio always PCM bug
-Known workarounds:
1. Generate SWF instead of MP4 (needs quality set to 100 to avoid visible quality loss; unfortunately this reduces video's compatibility across devices and media players);
2. Use PCM instead of LC-AAC (also reduces compatibility)
3. Use PCM and then use a transcoder to encode the audio track into LC-AAC (best workaround, but it needs an extra step; for transcoder anything from WinFF to MediaCoder will do)
-Final note: This discussion has as objective the resolving of the 2 issues mentioned above.
