[gst-devel] ffmux_mov: Failed to write file header - check codec settings

[Angelo Difino]

Hi all,
i've a problem with ffmux_mov (scenario is: copy elementary streams
from inside a mov to another mov). If i demux/mux an <h263 + raw
audio> no trouble
are reached, but if it try to do the same with <h263 +mp3> a "Failed
to write file header - check codec settings" message is reached.
Are there are any known compability issue between mov and mp3?

the correct media chain is: gst-launch-0.10 --gst-debug-level=3
filesrc location=testav_h263-raw.mov ! ffdemux_mov_mp4_m4a_3gp_3g2_mj2 name=d
{ d.video_00 ! queue ! identity ! queue ! m.video_00 }
{ d.audio_00 ! queue ! identity ! queue ! m.audio_00 }
ffmux_mov name=m ! filesink location=finale.mov

the bad media chain: gst-launch-0.10 --gst-debug-level=3
filesrc location=testav_h263-mp3.mov ! ffdemux_mov_mp4_m4a_3gp_3g2_mj2 name=d
{ d.video_00 ! queue ! identity ! queue ! m.video_00 }
{ d.audio_00 ! queue ! identity ! queue ! m.audio_00 }
ffmux_mov name=m ! filesink location=finale.mov
