  • MP3 + JPG of same name

    23 avril 2016, par user6162407

    For every mp3 file in my folder I have a certain jpg file with the same name, what I’m trying to achieve with cmd is making that name into one variable name without the file extension

    This is my code using only a mp3 name

    for %%a in ("*.mp3") do ffmpeg -i "%%a.mp3" -loop 1 -i Cover.jpg -c:v libx264 -tune stillimage -c:a aac -strict experimental -b:a 320k -pix_fmt yuv420p -vf scale=3000:3000 -shortest "%%~na.mp4"

  • What are supported ffmpeg rtp_mpegts Muxer options ? (mpegts Muxer options are ignored)

    7 mars 2020, par drake7

    I created a UDP stream with -f mpegts and some options like -mpegts_transport_stream_id.

    I received the stream with "StreamXpert - Real-time stream analyzer" that shows all options are in the output. See my ffmpeg parameters and the StreamXpert at the end.

    The same Muxer options seem to be ignored with -f rtp_mpegts.

    I have tried to use -f mpegts and pipe it to -f rtp_mpegts like so :

    ffmpeg -i ... -f mpegts pipe: | ffmpeg pipe: -c copy -f rtp_mpegts "rtp://239.1.1.9:1234?pkt_size=1316"

    The options are still ignored.

    This ticket "support options for MPEGTS muxer when using RTP_MPEGTS" also notices the ignored option. Furthermore in this comment, "thovo" gives an analysis and suggests a solution.

    Obviously the problem still exists. Anybody found a workaround for this ?

    My additional question : I have not questioned if my project really needs rtp in the first place. Maybe my coworker didn’t know better and requested rtp when udp would be sufficient as well.

    The aim was to receive the RTP stream with a TV using DVB via IP. This was successful an a Panasonic TV.

    The SAT>IP Specification on page 10 requires rtp for Media Transport :

    The SAT>IP protocol makes use of :

    • UPnP for Addressing, Discovery and Description,
    • RTSP or HTTP for Control,
    • RTP or HTTP for Media Transport.

    Is udp out of the equation ?
