  • FFmpeg/MP4 - Force all existing frames to play at fixed frame rate

    16 mai 2020, par MJoseph

    I have an MP4 video file that I suspect is corrupt, in that mediainfo reports a variable frame rate, but I believe the frames present are meant to be played at a fixed frame rate. This discrepancy causes video stuttering. Is there any way to force an MP4 container (by editing header info, or frame timing tables) to simply play back all existing frames at a fixed frame rate (i.e. 24fps). Every tip I've read assumes you want to drop and/or add frames to achieve a new frame rate, while keeping all the old frame timings (i.e. ffmpeg -r or ffmpeg -filter). These methods end up preserving the stutter and altering the size of the file. I would like to throw out the frame timings, but keep all frames, and just play them back at a constant rate. Is this possible ?

    


  • How to convert MPEG2-TTS to MPEG2-TS format to playback using ffplay

    29 février 2024, par Asustor

    I know some OSS such as ffmpeg or gstreamer don't support to play-back MPEG2-TTS stream.
Then, I tried to convert 192 bytes TTS packet to 188 bytes TS packet by deleting first 4 bytes like :

    


    def conv_tts2ts(rtp_payload):

    payload_len = len(rtp_payload)
    if payload_len % 192 != 0:
        raise

    pkt_num = int(payload_len / 192)
    ts_data = bytearray()
    for i in range(pkt_num):
        spos = 192 * i
        epos = spos + 192
        tmp = rtp_payload[spos:epos]
        ts_data.extend(tmp[4:])

    return ts_data

# after this, send ts_data with RTP header received from MPEG2-TTS streamer via UDP/IP.



    


    However, ffplay and ffprobe don't reaction.

    


    I expect to be able to play-back using ffplay as MPEG2-TS format.
Please tell me how to convert TTS to TS in order to deocde by ffmpeg ?

    


  • Orange pi 4 lts multimedia acceleration on rk3399 ( 4k hevc ) with MPP and hevc_rkmpp decoder

    7 juillet 2023, par DEMOSS-PRO

    Dear friends and specialists in SBC. Need your help in understanding how to get media acceleration with a decoder h264_rkmpp and hevc_rkmpp. I read the theme in armbian forum about multimedia library for rk3399, but it is old theme and not for OPI4 LTS version. i can't find any image contain armbian buster for my OPI.
I find some theme in Friendly elec forums, Github sources, but after two weeks of continuous attempts to compile a working version of ffmpeg and mpv, nothing worked for me. My hands drop. This task seems already overwhelming, but maybe someone can still help to get acceleration for mpv without using DM.

    


    https://www.armbian.com/orange-pi-4-lts/ - there is page for OPI 4 LTS image of armbian
Media Process Platform (MPP) module - there is information about MPP. i have succesfull compile it
https://forum.armbian.com/topic/23146-media-acceleration/ some questions about MM aceleration. some URLs is outdated
