  • Is there any possibility to transcode a h264 hls/m3u8 live stream into another HEVC (h265) hls/m3u8 live stream using FFmpeg in real time ?

    2 septembre 2024, par Ghenadie Pripa

    The command I used :

    


    ffmpeg -i  https://tezaurtv.md/wp-content/uploads/live/index.m3u8 -c:v libx265 -b:v 1500k -tag:v hvc1 -c:a aac -b:a 128k -f hls -hls_time 10 -hls_list_size 10 -hls_flags delete_segments+append_list+program_date_time -hls_playlist_type event -hls_segment_type mpegts -hls_segment_filename "D:/BRUT/HLS/test/stream_%d.ts" -vsync 2 -rtbufsize 500M -loglevel debug D:/BRUT/HLS/test/stream.m3u8


    


    I tried a lot of commands and parameters but nothing helps. The experiment is on local Windows. Transcode with ffmpeg and play with FFplay.

    


    The problem is the following : After I start stream.m3u8 to play after a few seconds the picture and sound stops. What is wrong in the FFmpeg command ?

Error while opening encoder for output stream #0:1 - maybe incorrect parameters such as bit_rate, rate, width or height

    It seems the problem is with audio’s bit per frame.
    Which might be the right solution ?

  • FFMPEG Error while opening decoder for input stream

    6 mars 2016, par Chris

    While this command his been working for a couple of months, I suddenly began running into the following error when encoding video via my php application. Testing the encoding parameters on the command line yielded the same results, while the verion of ffmpeg on my local machine has no problem reading the input

    Command I used :

    ffmpeg -i clip_20121022150813.mp4 -acodec libfaac -ab 44100 encoded.mp4

    And the output (error on last line) :
