  • Not getting required audio codec in ffmpeg

    5 juin 2020, par user13546893

    I am using Colab to run the code.

    



    import os, sys, re

video_file_path = "/content/drive/My Drive/1111/Mrs.Serial Killer 2020 1080p 10bit NF WEBRip Hindi DD+5.1 Atmos x265 HEVC ESub - MoviePirate - Telly.mkv" #@param {type:"string"}
os.environ['fileName'] = filename_raw
os.environ['fileExtension'] = file_extension_raw

!ffmpeg -hide_banner -i "$inputFile" -c copy -strict -2 "$outputPath"/"$fileName".mp4


    



    But the problem is after conversion of mkv video in mp4 format my html5 player can't play the audio. Video is running fine.
Output :

    What changes should I do in the Code ?

    


  • Set H264 high quality encoding in FFMPEG

    25 décembre 2015, par hiitiger

    I’m working on a function, using ffmpeg to encode a serial images to a MP4 file.
    I use H264 codec, and want to have a high quality output.

    Other things now goes well, but the video quality looks obvious loss.

    After some Google, I set codec context like this

    video_st = avformat_new_stream(oc, 0); 
    
....
    
pVideoCodec  = avcodec_find_encoder(fmt->video_codec); //AV_CODEC_ID_H264
    
....
    
avcodec_get_context_defaults3(video_st->codec, pVideoCodec);
    
video_st->codec->codec_id =  fmt->video_codec;
    
video_st->codec->width = m_outWidth;
    
video_st->codec->height = m_outHeight;
    
video_st->codec->time_base.den = m_fps;
    
video_st->codec->time_base.num = 1;
    
video_st->codec->pix_fmt = AV_PIX_FMT_YUV420P;
    

    
AVDictionary *param = nullptr;
    
av_dict_set(&param, "qp", "0", 0);
    
av_dict_set(&param, "preset", "medium", 0);

    I also try to set bit_rate. But all turned out to be bad.

    I want a visually loss less output video.

    So what parameters should I set or anything else did I missed ?

    Merge branch ’frame-parallel’ to enable frame parallel decode in master branch.

    In frame parallel decode, libvpx decoder decodes several frames on all
    cpus in parallel fashion. If not being flushed, it will only return frame
    when all the cpus are busy. If getting flushed, it will return all the
    frames in the decoder. Compare with current serial decode mode in which
    libvpx decoder is idle between decode calls, libvpx decoder is busy
    between decode calls. VP9 frame parallel decode is >30% faster than serial
    decode with tile parallel threading which will makes devices play 1080P
    VP9 videos more easily.

    * frame-parallel :
    Add error handling for frame parallel decode and unit test for that.
    Fix a bug in frame parallel decode and add a unit test for that.
    Add two test vectors to test frame parallel decode.
    Add key frame seeking to webmdec and webm_video_source.
    Implement frame parallel decode for VP9.
    Increase the thread test range to cover 5, 6, 7, 8 threads.
    Fix a bug in adding frame parallel unit test.
    Add VP9 frame-parallel unit test.
    Manually pick "Make the api behavior conform to api spec." from master branch.
    Move vp9_dec_build_inter_predictors_* to decoder folder.
    Add segmentation map array for current and last frame segmentation.
    Include the right header for VP9 worker thread.
    Move vp9_thread.* to common.
    ctrl_get_reference does not need user_priv.
    Seperate the frame buffers from VP9 encoder/decoder structure.
