Transcoding mjpeg stream from http://192.168.0.100:8080/video (address to IPWebcam stream in local network) and streaming it by HLS via ffmpeg app
Usage - now for test manually:
  • 1. Download ffmpeg and put it to: /mtd_rwcommon
    2. Set permissions:

    Code: Select all

    chmod +x /mtd_rwcommon/ffmpeg
    3. Create the directory: /dtv/www/hls
    4. Add new channel to TV channel list (*scm file) and to TvList.xml:

    Code: Select all

        <item>
          <tvid>999</tvid>
          <source>OnlineTV</source>
          <title>My IPWebCam</title>
          <link>http://127.0.0.1:1080/hls/playlist.m3u8</link>
          <image>None</image>
          <type>HLS</type>
          <ch_category>
            <id_category />
          </ch_category>
          <description> </description>
        </item>
    
    5. Put command via telnet:

    Code: Select all

    /mtd_rwcommon/ffmpeg -f mjpeg -r 8 -i "http://192.168.0.100:8080/video" -vcodec mpeg4 -r 25 -f ssegment -segment_list /dtv/www/hls/playlist.m3u8 -segment_list_type hls -hls_flags delete_segments -segment_list_size 10 -segment_list_flags +live -segment_time 10 /dtv/www/hls/out%03d.ts
    6. Run OnlineTV and play new channel
    7. Watch your stream... :D
For me it work's :D

Use CPU ~8%

This needs to be automated (in listCH.sh) and add scripts to delete unnecessary files from the directory: /dtv/www/hls
Any idea to use similar approach to transcode dvb subtitles into the video.

I managed to do it on my pc with static files but I can't do it on the tv with live video

ffmpeg -i video.ts -filter_complex '[0:v][0:s]overlay[v]' -map '[v]' -map 0:a video.mp4

This is the stream which I am trying to transcode

Code: Select all

    Metadata:
      service_name    : TV 1
      service_provider: TV
    Stream #0:0[0x1979]: Video: mpeg2video (Main) ([2][0][0][0] / 0x0002), yuv420p(tv, top first), 720x576 [SAR 64:45 DAR 16:9], 15000 kb/s, 25 fps, 25 tbr, 90k tbn, 50 tbc
    Stream #0:1[0x197c]: Audio: mp2 ([3][0][0][0] / 0x0003), 48000 Hz, stereo, s16p, 192 kb/s
    Stream #0:2[0x197b](bul): Subtitle: dvb_subtitle ([6][0][0][0] / 0x0006)
    Stream #0:3[0x197e]: Data: bin_data ([6][0][0][0] / 0x0006)
I can see the transcoded subtitles but the framerate is slow here is the complex command which I am testing

Code: Select all

ffmpeg -f mpegts -r 8 -i "http://streamIp/tv.ts"  -vcodec mpeg4 -r 25 -f ssegment -segment_list playlist.m3u8 -segment_list_type hls -hls_flags delete_segments -segment_list_size 10 -segment_list_flags +live -segment_time 10 -filter_complex '[0:v][0:s]overlay[v]' -map '[v]' -map 0:a out%03d.ts
When I start it on the tv I am getting this:

Code: Select all

edit
Does it work on your PC for live video also?

At the first place some codecs are missing, I just updated my post with logs from the tv.

So we need to crosscompilled from the latest source right? Do you know which switches we should use? Thanks

I did a cross compile for a default configure of args.
It works for me also for windows compilation with args:

Code: Select all

configuration: --enable-gpl --enable-version3 --disable-w32threads --enable-dxva2 --enable-libmfx --enable-nvenc --enable-avisynth --enable-bzlib --enable-libebur128 --enable-fontconfig --enable-frei0r --enable-gnutls --enable-iconv --enable-libass --enable-libbluray --enable-libbs2b --enable-libcaca --enable-libfreetype --enable-libgme --enable-libgsm --enable-libilbc --enable-libmodplug --enable-libmp3lame --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libopenh264 --enable-libopenjpeg --enable-libopus --enable-librtmp --enable-libschroedinger --enable-libsnappy --enable-libsoxr --enable-libspeex --enable-libtheora --enable-libtwolame --enable-libvidstab --enable-libvo-amrwbenc --enable-libvorbis --enable-libvpx --enable-libwavpack --enable-libwebp --enable-libx264 --enable-libx265 --enable-libxavs --enable-libxvid --enable-libzimg --enable-lzma --enable-decklink --enable-zlib
my cross compilation args:

Code: Select all

configuration: --disable-yasm --disable-ffplay --disable-ffprobe --disable-doc --disable-txtpages --disable-podpages --disable-manpages --disable-htmlpages --disable-fft --cross-prefix=/opt/arm-2014.05/bin/arm-none-linux-gnueabi- --enable-cross-compile --target-os=linux --arch=armv7 --enable-static --disable-shared --disable-cuda --enable-pic --extra-cflags=--static --extra-libs=-static
First we need to find which arguments allow to add subtitle to a video :D
edit
it works nice on PC (without slow motion and with best video quality):

Code: Select all

ffmpeg -i "http://my_stream" -f ssegment -segment_list playlist.m3u8 -segment_list_type hls -hls_flags delete_segments -segment_list_size 10 -segment_list_flags +live -segment_time 10 -filter_complex [0:v][0:s]overlay[v]  -map [v] -map 0:a -c:v libx264  -c:a copy out%03d.ts

Probably we need new cross compile with two new args:

Code: Select all

--enable-libfontconfig   enable libfontconfig, useful for drawtext filter [no]
--enable-libx264         enable H.264 encoding via x264 [no]
