ffprobe - getting video info from file chunk
13 septembre 2015, par andrzej1_1On my site users can upload videos, which are encrypted on the fly and stored on another server. I want to store video bitrate, frame rate etc., but I have not direct access to them and I can not just use the following command :
ffprobe -show_streams -i file.mp4
I tried saving last chunk on my server, which contain moov atom, but ffprobe is outputting :
Format mov,mp4,m4a,3gp,3g2,mj2 detected only with low score of 1, misdetection possible!
moov atom not found
C:\file.mp4: Invalid data found when processing inputI checked and truncating at least one byte cause this, although moov atom is intact.
What is the proper way to get video metadata from file fragment containg moov atom ? What about getting informations from piece of mdata atom ?

FFmpegWriter::setAudioOptions not accepting the codec in info object of the reader
9 août 2015, par Pradyumna DasI am using libopenshot library for video editing.
I am trying to edit a video and write the edited video using the same audio and video codecs used in the source video. This is what I am doing :
FFmpegReader* ivr = new FFmpegReader("testvid.mp4");
FFmpegWriter w("outpiut.mp4");
w.SetAudioOptions(true, ivr->info.acodec, ivr->info.sample_rate, ivr->info.channels, ivr->info.channel_layout, ivr->info.audio_bit_rate);
w.SetVideoOptions(true, ivr->info.vcodec, openshot::Fraction(24,1), 720, 480, openshot::Fraction(1,1), false, false, 300000);While debugging I can see that ivr->info.acodec = "aac" and ivr->info.vcodec = "h264".
This code keeps throwing the error :
[mov,mp4,m4a,3gp,3g2,mj2 @ 0x112ed40] multiple edit list entries, a/v desync might occur, patch welcome
[mov,mp4,m4a,3gp,3g2,mj2 @ 0x11365e0] multiple edit list entries, a/v desync might occur, patch welcome
terminate called after throwing an instance of 'openshot::InvalidCodec'Need some help figuring out what I am doing wrong here.
