AMV, these S1 MP3 players claim to support MP4 videos but in reality suport the. Video:4339kB audio:675kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: 0.Many of you must have seen highly popular and very cheap chinese MP3/MP4/MTV players su pporting a not so well known video format. Guessed Channel Layout for Input Stream #0.1 : monoĭuration: N/A, start: 0.000000, bitrate: N/A (This file has been generated by broken software.) Try -block_size 1378Ĭould not write header for output file #0 (incorrect codec parameters ?): Invalid argumentĭo you know, what I am missing in the command or how I could make it work? I am quite new in ffmpeg.ītw: One AMV video that I tried to copy by ffmpeg to find out how it is made get following result during copying if it helps: deprecated pixel format used, make sure you did set range correctly The errors: Pure channel mapping detected: 0 I've also tried to change it to mono as following but there were just got even more errors:įfmpeg.exe -i "c:\source160x120.mp4" -c:v amv -c:a adpcm_ima_amv -pix_fmt yuvj420p -vstrict -1 -s 160x120 -ar 22050 -b:a 40400 -af pan="mono| c0=FL" "c:\destination.amv" Parameters such as bit_rate, rate, width or height While opening encoder for output stream #0:1 - maybe incorrect However I am still getting following errors: Only mono is supported Error initializing output stream 0:1 - Error So I've created a video with the same size and tried various types of commands, following at last:įfmpeg.exe -i "c:\source160x120.mp4" -c:v amv -c:a adpcm_ima_amv -pix_fmt yuvj420p -vstrict -1 -s 160x120 -ar 22050 -b:a 40400 "c:\destination.amv"
So I've found that there should be bitrate for sound 22050 for sound with adpcm_ima_amv sound format, pixel format should be probably yuvj420p and the video size should be probably 160x120. I've searched through web about the appropriate formatand and also tried to check another AMV video parametrs. I am trying to convert a MPEG4 video to AMV via ffmpeg.
