  • Re-encode video stream only with ffmpeg (and with all audio streams)

    25 septembre 2016, par razr

    I’m looking for a way to re-encode the video stream of a movie only and keep all other streams as they are using ffmpeg or more specific streamio/streamio-ffmpeg (Github - StreamIO-FFMPEG).

    I already tried various combinations of -map 0 or -map a:0 -map s:0, but in all combinations I tried, either nothing is encoded at all, or not all other streams are copied to the new file. In most cases there is only one audio stream after encoding, when there were two before, and sometimes the subtitle streams are lost, too. Also most times the info what language the streams are in gets lost.

    So when I have a movie file (mkv) with the following streams :

    0: video [H.264, 1080p]
    
1: audio [english, mp3]
    
2: audio [french, mp3]
    
3: subtitle [english (forced)]
    
4: subtitle [english]

    What should the ffmpeg parameters be, if I want to encode the video file to H.265 and 720p and keep all other streams as they are ?

    What should the parameters be, if I additionally want to encode the audio streams as AAC ?

    Thanks in advance !

  • hw_base_encode : make recon_frames_ref optional

    hw_base_encode : make recon_frames_ref optional

    Vulkan supports some stupidly odd hardware, that unfortunately,
    
most modern GPUs happen to be.
    
The DPB images for encoders may be required to be preallocated
    
all at once, and rather than be individual frames, be layers of
    
a single frame.
    

    As the hw_base_encode code is written with the thought that either
    
the driver or the device itself supports sane image allocation,
    
Vulkan does not leave us with this option.
    

    So, in the case that the hardware does not support individual
    
frames to be used as DPBs, make the DBP frames context optional,
    
and let the subsystem manage this.

  • ffmpeg how to convert pgs subtitles to srt

    20 mai 2015, par 8ofspades

    I’m having an issue with extracting subtitles from ffmpeg 2.6.2. I have an mkv file with 6 subtitle streams, and I would like to generate srt files for all of them. My ffprobe output for the streams is below.

        Stream #0:0(eng): Video: h264 (High), yuv420p, 1280x720 [SAR 1:1 DAR 16:9], 29.97 fps, 29.97 tbr, 1k tbn, 59.94 tbc (default)
    
Stream #0:1(ita): Audio: ac3, 48000 Hz, stereo, fltp, 448 kb/s (default)
    
Stream #0:2(ita): Audio: dts (DTS), 48000 Hz, 5.0(side), fltp, 1536 kb/s

Stream #0:8(spa): Subtitle: hdmv_pgs_subtitle

  title           : Spanish

    The russian (subrip) subtitles work fine with

    ffmpeg -i input.mkv -c:s:0 copy sub_ru.srt

    however when I try and select and of the other (pgs) subtitle streams, it ignores the stream I selected and outputs the russian (stream 0:3) subtitles.

    I’m not sure if this an issue with my ffmpeg command or the fact that the other streams are pgs.

    Thanks
