[FFmpeg-user] Transcoding captured videos to make them viewable in both iOS/Android HTML5 WebViews

Wed Mar 16 21:59:55 CET 2016

Hello,
I wish for ffmpeg transcoded videos sourced from the cameras of Android 6 (3gpp) and iOS 9 (h264) to be viewable on each other's devices in their HTML5 WebView components, but so far whatever arguments I use for ffmpeg, the resulting videos only play on the same phone/platform the video was captured from. The commands for ffmpeg have always succeeded and produced their output. Might you know what is the problem?
Command lines I have used for ffmpeg 2.7.6-0ubuntu0.15.10.1:
1. ffmpeg -i video.3gp -c:v libx264 -crf 23 -profile:v baseline -level 3.0 -pix_fmt yuv420p -c:a aac -ac 2 -strict experimental -b:a 128k -movflags faststart output.mp4
2. ffmpeg -i video.3gp -c:v libx264 -profile:v baseline -c:a aac -strict experimental -ac 2 -b:a 128k -movflags faststart output.mp4
3. ffmpeg -i video.3gp -c:v libx264 -profile:v main -level 3.1 -crf 23 -x264-params ref=4 -c:a aac -ac 2 -strict experimental -b:a 128k -movflags +faststart output.mp4
4. ffmpeg -i video.3gp -acodec aac -ab 128k -strict experimental -vcodec mpeg4 -b:v 1200k -mbd 2 -flags +4m -cmp 2 -subcmp 2 output.mp4
Output:
