  • av_interleaved_write_frame return 0 but no data written

    11 août 2015, par Jerikc XIONG

    I use the ffmpeg to stream the encoded aac data , i use the

    av_interleaved_write_frame()

    to write frame.

    The return value is 0,and it means success as the description.

    Write a packet to an output media file ensuring correct interleaving.

    The packet must contain one audio or video frame. If the packets are already correctly interleaved, the application should call av_write_frame() instead as it is slightly faster. It is also important to keep in mind that completely non-interleaved input will need huge amounts of memory to interleave with this, so it is preferable to interleave at the demuxer level.

    Parameters

    s media file handle

    pkt The packet containing the data to be written. pkt->buf must be set to a valid AVBufferRef describing the packet data. Libavformat takes ownership of this reference and will unref it when it sees fit. The caller must not access the data through this reference after this function returns. This can be NULL (at any time, not just at the end), to flush the interleaving queues. Packet’s stream_index field must be set to the index of the corresponding stream in s.streams. It is very strongly recommended that timing information (pts, dts duration) is set to correct values.

    Returns

    0 on success, a negative AVERROR on error.

    However, I found no data written.

    What did i miss ? How to solve it ?

  • Spaces in variable

    13 avril 2012, par Roger

    I am facing some problems with spaces in variables :

    ALBUM=&#39; -metadata album="Peregrinações Alheias"&#39;

    This command :

    ffmpeg -i $R_IMG -r 1 -b 1800 -i $SOUND -acodec libmp3lame -ab 128k "$ALBUM" -y $OUT

    Returns :

    Unable to find a suitable output format for &#39; -metadata album="Peregrinações Alheias"&#39;

    And if I take out the "" from the variable :

    ffmpeg -i $R_IMG -r 1 -b 1800 -i $SOUND -acodec libmp3lame -ab 128k $ALBUM -y $OUT

    Returns :

    Unable to find a suitable output format for &#39;Alheias"&#39;

    And I am sure I am missing something in the bash sintax...

    UPDATE :

    So it looks that the matter is not with spaces but with the "-metadata" argument...

    The problem is that I have many metadata and I'd like to put them in just one variable. Like this :

    META=&#39; -metadata album="Peregrinações" -metadata title="Passeio ao PETAR" -metadata author="Rogério Madureira" -metadata date="2012" -metadata description="Áudio de um passeio ao PETAR" -metadata comment="Áudio capturado com TACAM DR-07MKII e Foto capturada com Canon PowerShot S5IS" &#39;

    And then :

    ffmpeg -i $R_IMG -r 1 -b 1800 -i $SOUND -acodec libmp3lame -ab 128k $META -y $OUT
