Is the concat protocol limited to certain filetypes?
I am trying to transcode and join 2 MP4 files, recorded
by a Panasonic HC-V10 camcorder.
Source files:
http://x32.elijst.nl/S1000001.MP4
http://x32.elijst.nl/S1000002.MP4
Commandline:
ffmpeg.exe -i concat:"S1000001.MP4|S1000002.MP4" -vf scale=384:288 \
-aspect 4:3 -sws_flags bicubic -vcodec libx264 \
-b 320k -r 25 -strict -2 -acodec aac -ab 96k -ar 48000 -ac 2 \
-x264opts

mp4concat-ffmpeg.mp4
Output:
http://x32.elijst.nl/mp4concat-ffmpeg.mp4
The output is byte by byte identical to a transcode of the
first file alone. FFmpeg just stops after the first one.
If I transcode the files one by one all goes as expected.
Is there any way to do a concat on these MP4 files?
Complete and uncut output follows below.
