Thanks for the suggestion but that didn't work for me I get the error
message:
Output #0, flv, to 'ceilidh_item.flv':
Stream #0.0: Video: flv, yuv420p, 640x480, q=2-31, 0 kb/s, 90k tbn, 30
tbc
Stream #0.1: Audio: pcm_u8, 11024 Hz, mono, s16, 88 kb/s
Stream mapping:
Stream #0.0 -> #0.0
Stream #0.1 -> #0.1
[NULL @ 0x6d3950]flv does not support that sample rate, choose from (44100,
22050, 11025).
Could not write header for output file #0 (incorrect codec parameters ?)
I tried with "-ar 11025" but that didn't work either I got the exact same
error message.
