    • Does ffmpeg not support H264?

    Is this bug or feature that ffplay can’t playing video without audio/video stream? I need to run ffplay programmatically from my java test application to view loadout of my service.

    P.S: I also tried adding the options "-nodisp -an", but that provided the same result as mentioned above.

  • FFmpeg : Error occurred while encoding audio stream from ac3 to aac

    4 December 2015, by akki_2891

    I am using following command to encode my video to h264 and aac audio codec :

    ffmpeg -i sample.mp4 -codec:v libx264 -profile:v high -level:v 4.0 -codec:a libvo_aacenc -b:a 128k output_file.mp4

    I am really not able to find what possibly could be wrong. I dont want to copy audio codec , i wish to encode it from ac3 to aac

    Also any suggestion to make it lossless
