• Ffmpeg Android - First image is skipped while making a slideshow

  17 mars 2021, par M. Bilal Asif

  Issue : I have 7 images in a list (with different size, resolution and format). I am adding an mp3 audio file and fade effect while making a slideshow with them, as i am trying to do it by following command

  


  val inputCommandinitial = arrayOf("-y", "-framerate", "1/5")&#xA;val arrTop = ArrayList<string>()&#xA;&#xA; //Add all paths&#xA;    for (i in images!!.indices) {&#xA;        arrTop.add("-loop")&#xA;        arrTop.add("1")&#xA;        arrTop.add("-t")&#xA;        arrTop.add("5")            &#xA;        arrTop.add("-i")&#xA;        arrTop.add(images!![i].path)&#xA;    }&#xA;&#xA;    //Apply filter graph&#xA;    arrTop.add("-i")&#xA;    arrTop.add(audio!!.path)&#xA;    arrTop.add("-filter_complex")&#xA;&#xA;    val stringBuilder = StringBuilder()&#xA;&#xA;    for (i in images!!.indices) {&#xA;        stringBuilder.append("[$i:v]scale=720:1280:force_original_aspect_ratio=decrease,pad=720:1280:(ow-iw)/2:(oh-ih)/2,setsar=1,fade=t=in:st=0:d=1,fade=t=out:st=5:d=1[v$i];")&#xA;    }&#xA;&#xA;    for (i in images!!.indices) {&#xA;        stringBuilder.append("[v$i]")&#xA;    }&#xA;&#xA;    //Concat command&#xA;    stringBuilder.append("concat=n=${images!!.size}:v=1:a=0,fps=25,format=yuv420p[v]")&#xA;&#xA;    val endcommand = arrayOf("-map", "[v]", "-map", "${images!!.size}:a", "-c:a", "copy", "-preset", "ultrafast", "-shortest", outputLocation.path)&#xA;    val finalCommand = (inputCommandinitial &#x2B; arrTop &#x2B; stringBuilder.toString() &#x2B; endcommand)&#xA;</string>

  


  But, it skips the first image and shows the rest 6 images and video output duration is 30 seconds, i've been trying since 3 days now

  


  Requirement :
making a slideshow with different format, size, resolution etc, i.e. picked by user from gallery and show in slideshow adding an audio behind, with fade effect

• Google Speech API returns empty result for some FLAC files, and not for the others although they have same codec and sample rate

  15 mars 2021, par Chad

  Below code is what I used to make request for transcription.

  


  import io
from google.cloud import speech_v1p1beta1 as speech
def transcribe_file(speech_file):
    """Transcribe the given audio file."""

    client = speech.SpeechClient()

    encoding = speech.RecognitionConfig.AudioEncoding.FLAC
    if os.path.splitext(speech_file)[1] == ".wav":
        encoding = speech.RecognitionConfig.AudioEncoding.LINEAR16
    with io.open(speech_file, "rb") as audio_file:
        content = audio_file.read()

    audio = speech.RecognitionAudio(content=content)
    config = speech.RecognitionConfig(
        encoding=speech.RecognitionConfig.AudioEncoding.FLAC,
        sample_rate_hertz=32000,
        language_code="ja-JP",
        max_alternatives=3,
        enable_word_time_offsets=True,
        enable_automatic_punctuation=True,
        enable_word_confidence=True,
    )

    response = client.recognize(config=config, audio=audio)
    #print(speech_file, "Recognition Done")
    return response


  


  As I wrote in title, the results of response has empty list for some files, and not for some files.
They have same sample rate and codec(32000, FLAC)

  


  Below is the result of ffprobe -i "AUDIOFILE" -show_streams for one of each cases.

  


  Left one is empty one. The only difference is duration of file.

  


  How can I get non empty results ?

  


  Result of ffprobe

  


  Edit :

  


  Result of ffprobe show stream show format

  


  Something not captured in one screen

  


  Sadly, re-mux didn't work.

  


  I used ffmpeg-git-20210225

• ffmpeg - 'hevc' codec changed to 'rawvideo' after copying video codec

  11 mars 2021, par Md Yeamin

  I am trying to convert some mkv videos with hevc codec to avi format. For this I run the following command :

  


  ffmpeg -i input.mkv -vcodec copy -acodec copy out.avi


  


  For some video this command works without any issue. But in some cases video does converted, but I can not play those files in any video player. I've tried several video players including VLC, SMPlayer, Deepin Movie etc.

  


  After looking into the video codec of converted video I can see that the video codec got transformed from hevc to rawvideo. Hers is the stream information of the original and the converted video files :
