  • lossless video to h.265 - [error] : main10 profile not compatible with i422 input chroma subsampling

    24 février 2021, par spierce7

    I have a lossless .mov video and I'm trying to encode using h.265 for firetv and some other android tv devices. The spec that they support is :

    


    Based on their native H.265 support, I'm trying to export a Main 10 Profile with level 4.1.

    


    The command I'm running is :

    


    ffmpeg -i 001_lossless.mov -c:v libx265 -preset slow -profile:v main10 -level:v 4.1 -c:a aac -b:a 128k output.mp4


    


    Which yields the following error :

    


    x265 [error]: main10 profile not compatible with i422 input chroma subsampling.


    


    What is the best way to work around this ? I can request the lossless video in different formats also, but I'm not exactly sure what to ask for.

    


  • ffmpeg errors out with Error initializing output stream 0:0 for the setting `-profile:v main`

    17 octobre 2020, par Vishwasa Navada K

    We are using ffmpeg for generating HSL streaming files (.m3u8, .ts) from multiple type of input video and audio like avi, mp4, mp3, mkv, m4a etc. We are trying to encode everything into h264 streams to support modern browsers. But we are facing issues in converting few videos of type avi and mp4 (not all). Below is the ffmpeg command (it's using ffmpeg fluent on NodeJS).

    


    ffmpeg(fileName)
  .outputOptions([
    '-c:v h264',
    '-profile:v main',
    `-vf scale=1280:-2`,
    '-hls_list_size 0',
    '-start_number 0',
    '-hls_time 10',
    '-loglevel error',
  ])
  .output(output_file_path)


    


    When we try to run this with some set of specific avi and mp4 samples, it errors out saying
Error: ffmpeg exited with code 1: Error initializing output stream 0:0 -- Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height.

    


    I tried changing few commands (like providing crf value) and tried to run them, The only time it successfully converted converted them was when I removed the output option -profile:v main. I am not sure about the reason behind it.

    


    I ran ffprobe to get the information from the videos that were not able to generate streams. I have them uploaded to gist here : https://gist.github.com/vishwasnavadak/91b5c978e2a3cb7a7c7a2bb505487263

    


    Is there something I am missing ? What is the reason for it to error out when -profile:v main option is present ?
