  Issues with conversion after ffmpeg version upgrade

  Hi,

  We are using ffmpeg to covert audios and videos from one format to other format.

  New version Details:

  We are facing issues with following conversions.
  1. .MP4, .M2TS, .MOV and NTSC encoded video files to MKV/FLV/AVI formats

  Commands used :
  a. To FLV
  ffmpeg.exe -i “D:Test DataVideosVideos all1_02_livingdead_NTSC.mov” -sameq -acodec libmp3lame -ac 2 -ar 22050 -ab 96000 -filter:v yadif -nr 500 -r 20 -g 500 -b 1200000 -me_range 20 -s 128X96 -report -y “D:Test DataVideosT_OutputFLV1_01_02_livingdead_NTSC.flv”
  b. To MKV
  ffmpeg.exe -i “D:Test DataVideosVideos all1_02_livingdead_NTSC.mov” -sameq -acodec libmp3lame -ac 2 -ar 22050 -ab 96000 -filter:v yadif -nr 500 -f flv -r 20 -g 500 -b 1200000 -me_range 20 -s 128X96 -report -y “D:Test DataVideosT_OutputMKV1_01_02_livingdead_NTSC.mkv”
  c. To AVI
  ffmpeg.exe -i “D:Test DataVideosVideos all1_02_livingdead_NTSC.mov” -sameq -acodec libmp3lame -ac 2 -ar 22050 -ab 96000 -vcodec mpeg4 -filter:v yadif -nr 500 -f avi -r 20 -g 500 -b 120k -me_range 20 -s 128X96 -report -y “D:Test DataVideosT_OutputAVI1_01_02_livingdead_NTSC.avi”

  2. .RAM, .APE, .RA, .AIFF audio files to MP3/MP4/WMA formats

  Commands Used:
  a. To MP3
  ffmpeg.exe -i “D:Test DataAudioTESTSRCdoublesize.ram” -ab 128000 -ac 2 -acodec libmp3lame “D:Test DataAudioTESTMP30_doublesize.mp3”
  b. To MP4
  ffmpeg.exe -i “D:Test DataAudioTESTSRCdoublesize.ram” -ab 128000 -ac 2 -acodec libmp3lame “D:Test DataAudioTESTMP40_doublesize.mp4”
  c. To WMA
  ffmpeg.exe -i “D:Test DataAudioTESTSRCdoublesize.ram” -ab 128000 -ac 2 -acodec wmav2 “D:Test DataAudioTESTWMA0_doublesize.wma”

  When I run these commands, It throws error like
  “Could not write header for output file #0 (incorrect codec parameters ?): Operation not permitted” and a 0KB file is created as output.

  Am I going wrong somewhere.. Do I need to do some rectifications in the commands?
  Any Pointers will be helpful.
